RESUMO
ABSTRACT Purpose: To determine the relationship of ocular surface disease, the number of glaucoma medications prescribed and its influence on treatment adherence. Methods: In this cross-sectional study, demographic data of patients with glaucoma were collected, and patients completed the ocular surface disease index questionnaire and the glaucoma treatment compliance assessment tool. Ocular surface parameters were assessed by "Keratograph 5M." Patients were stratified into two groups according to the amount of prescribed ocular hypotensive eye drops (Group 1, one or two classes of medications; Group 2, three or four classes) Results: In total, 27 eyes of 27 patients with glaucoma were included: 17 using 1 or 2 topical medications (Group 1) and 10 eyes using 3 or 4 classes (Group 2). For the Keratograph assessment, patients using ≥3 medications had significantly smaller tear meniscus height (0.27 ± 0.10 vs. 0.43 ± 0.22; p=0.037). The analysis of Ocular Surface Disease Index questionnaire showed higher scores among the groups using more hypotensive eye drops (18.67 ± 13.53 vs. 38.82 ± 19.72; p=0.004). Regarding the glaucoma treatment compliance assessment tool, Group 2 had worse scores in components of forgetfulness (p=0.027) and barriers due to lack of drops (p=0.031). Conclusion: Patients with glaucoma using more hypotensive eye drops had worse tear meniscus height and ocular surface disease index scores than those using fewer topical medications. Patients using three or four drug classes had worse predictors of glaucoma adherence. Despite worse ocular surface disease results, no significant difference in self-reported side effects was found.
RESUMO Objetivo: Determinar a relação entre doença da superfície ocular (OSD), número de medicamentos prescritos para o glaucoma, e como isso influencia na adesão ao tratamento. Métodos: Neste estudo transversal, pacientes com glaucoma foram submetidos à coleta de dados demográficos, preenchimento do questionário Ocular Surface Disease Index e do Glaucoma Treatment Compliance Assessment Tool. Os parâmetros da superfície ocular foram avaliados pelo "Keratograph 5M". Indivíduos foram estratificados em 2 grupos de acordo com a quantidade de colírios hipotensores oculares prescritos (Grupo 1: uma ou duas classes de medicamentos; Grupo 2: três ou quatro classes). Resultados: No total, 27 olhos de 27 pacientes com glaucoma foram incluídos: 17 usando 1 ou 2 medicamentos tópicos (Grupo 1) e 10 olhos usando 3 ou 4 classes (Grupo 2). Na avaliação do Keratograph, os pacientes em uso de 3 ou mais medicamentos apresentaram altura do menisco lacrimal significativamente menor (0,27 ± 0,10 vs. 0,43 ± 0,22; p=0,037). Análise do questionário OSDI mostrou escores mais altos entre o grupo que usou mais colírios hipotensores (18,67 ± 13,53 vs. 38,82 ± 19,72; p=0,004). Em relação ao Glaucoma Treatment Compliance Assessment Tool, o Grupo 2 apresentou piores escores nos componentes de esquecimento (p=0,027) e barreiras por falta de colírios (p=0,031). Conclusão: O estudo demonstrou que pacientes com glaucoma usando mais colírios hipotensivos apresentaram piores escores de altura do menisco lacrimal e Ocular Surface Disease Index, em comparação com aqueles que usaram menos medicamentos tópicos. Pacientes em uso de 3 ou 4 classes de colírios tiveram piores preditores de adesão ao glaucoma. Apesar dos piores resultados de doença da superfície ocular, não houve diferença significativa nos efeitos colaterais relatados.

INTRODUCTION/PURPOSE: The aim of this study was to compare two surgical revision techniques in failed trabeculectomies after 6 months. METHODS: Patients diagnosed with open-angle glaucoma who underwent trabeculectomy in at least one eye with uncontrolled intraocular pressure (IOP) after trabeculectomy performed at least 6 months before were enrolled in this prospective trial. All participants underwent a complete ophthalmological examination at baseline. Randomization was performed to one eye per patient to double-masked trabeculectomy revision or needling. Patients were examined on the first day, 7 days, 14 days, and then monthly until completing 1 year after surgical intervention. All follow-up visits included the following: patients reported ocular and systemic events, best-corrected visual acuity, IOP, slit-lamp examination, and optic disc evaluation for cup-to-disc ratio. Gonioscopy and stereoscopic optic disc photographs were taken at baseline and 12 months. After 1-year, the IOP and number of medications were compared between the groups. Absolute success criteria in the study were IOP <16 mm Hg, for 2 consecutive measurements without using a hypotensive medication. RESULTS: Forty patients were included in this study. Among them, 38 completed 1-year follow-up (18 in revision group and 20 in needling group). The age ranged from 21 to 86 years, with a mean of 66.82 ± 13.44. At baseline, the average IOP was 21.64 ± 5.12 mm Hg (range from 14 to 38 mm Hg) in the entire group. All patients were using at least two classes of hypotensive eye drops, and 3 patients were using oral acetazolamide. The mean use of hypotensive eye drop medications was 3.11 ± 0.67 at the baseline for the entire group. In the present study, 58% of the patients presented complete success, 18% qualified success, and 24% failed in both groups. After 1-year treatment, both techniques were similar for IOP parameters and also for number of medications (p = 0.834 and p = 0.433, respectively). Regarding intra- or postoperative complications, one patient in each group needed a new surgical intervention, one in the needling group due to shallow anterior chamber and one in the revision group due to spontaneous Seidel sign, and one patient in the needling group underwent posterior revision due to fail. CONCLUSIONS: Both techniques were safe and effective for IOP control after 1 year of follow-up in patients who underwent to trabeculectomy more than 6 months before.

This prospective study aimed to compare vascular parameters (endothelin-1 [ET-1] blood levels, laser Doppler imaging [LDI] of distal phalanxes, and nailfold capillaroscopy) between open-angle glaucoma patients with low- and high-tension optic disc hemorrhages (LTDH and HTDH, respectively). The 33 enrolled patients (mean age, 62.3 ± 13 years) were classified as LTDH or HTDH if they presented at the time of DH detection an intraocular pressure (IOP) < 16 mmHg or ≥ 16 mmHg, respectively. Demographic and ophthalmological data, ET-1 concentrations, LDI (before and 1, 10, and 20 min after cold stimulation), and nailfold capillaroscopy findings were evaluated. The ET-1 blood level was 65% higher in the LTDH (2.27 ± 1.46 pg/ml) than in the HTDH (1.37 ± 0.57 pg/ml; p = 0.03) group. Moreover, there was a statistically significant negative correlation between ET-1 blood concentration and IOP at the time of DH detection (r = -0.45, p = 0.02). Blood flow measurements 10 and 20 min after cold stimulation were lower in the LTDH group than in the HTDH group (p < 0.01). Patients developing DH with lower IOPs have higher ET-1 blood levels and more peripheral vascular dysfunction as estimated by LDI than those with higher IOPs. These findings suggest that distinct underlying mechanisms may be involved in patients developing DH within different IOP ranges.

INTRODUCTION: COVID-19 is a major public health concern in this century. The causative agent SARS-CoV-2, is highly contagious and spreads continuously across territories. Spatial analysis is of enormous importance in the process of understanding the disease and its transmission mechanisms. We aimed to identify the risk areas for COVID-19 and analyze their association with social vulnerability in Maceió, Alagoas. The study was conducted in 2020. METHODOLOGY: This is an ecological study to evaluate the incidence, mortality and case fatality rate of COVID-19 and their relationship with 12 indicators of human development and social vulnerability. Multivariate and spatial statistics were applied. A 95% confidence interval and a 5% confidence level were considered. RESULTS: The spatial scan statistic revealed the existence of six high-risk clusters for the incidence of COVID-19. The regression model showed that social indicators, such as literacy of people, residents of private households, households with more than four residents, and resident brown population, were associated with COVID-19 transmission in Maceió-AL. The disease affected localities whose populations are exposed to a context of intense socioeconomic vulnerability. CONCLUSIONS: Based on the results, it is necessary to adopt measures that take into account the social determinants of health in order to minimize the damage caused by the pandemic.

PURPOSE: To correlate optical coherence tomography (OCT) measurements with clinical parameters in idiopathic intracranial hypertension (IIH). METHODS: A cross-sectional study was conducted with 22 patients with IIH and 11 controls. All participants underwent comprehensive ophthalmological examination followed by spectral-domain OCT (SD-OCT) and standard automated perimetry using the 30-2 program of the Humphrey visual field analyzer. Correlations between ganglion cell complex (GCC) thickness and retinal nerve fiber layer (RNFL) thickness, as measured by SD-OCT, and clinical parameters were assessed using generalized estimating equations. RESULT: The mean age of the participants was 35.0 ± 10.83 years. The groups were similar regarding age, but were significantly different regarding sex and visual acuity (p=0.001 and p=0.038, respectively). The GCC was significantly thinner in the IIH group, with a mean of 90.535 ± 9.766 µm compared to 98.119 ± 6.988 µm for the controls (p=0.023). There was a significant association between GCC thickness and optic disc pallor (p=0.016) and between edema and visual acuity (p=0.037). No significant difference was found in RNFL thickness between patients and controls. CONCLUSION: The GCC was thinner in the patients with IIH compared to the controls, and there was an association between GCC and optic disc pallor. This might suggest a role for OCT parameters when the structural changes that occur in IIH are investigated, possibly guiding clinical decision making.
RESUMO
INTRODUCTION: This study aimed to evaluate the characteristics of the filtering bleb in failed late trabeculectomy and the agreement between glaucoma specialist assessment and anterior segment-optical coherence tomography (AS-OCT) system assessment in terms of the presence of subconjunctival fluid in the filtering bleb. METHODS: Patients with a diagnosis of glaucoma who were scheduled to undergo trabeculectomy in at least one eye and with uncontrolled intraocular pressure (IOP) were enrolled. All participants underwent a complete ophthalmological examination. The presence of fluid under the filtering bleb was first evaluated by a glaucoma specialist using biomicroscopy evaluation and then using the OCT 1000 AS-OCT Version 3.0.1.8 (Carl Zeiss Meditec, Dublin, CA, USA) system. A Kappa statistical test was used to evaluate the agreement between AS-OCT and the examiner. The correlation between conjunctiva and tenon thickness and clinical parameters was also assessed. RESULTS: Forty eyes of 40 patients were evaluated in this study. The ages ranged from 21 to 86 years, with a mean of 66.55 ± 12.33. The average IOP was 21.20 ± 4.44 mm Hg (range 14-38 mm Hg) in the entire group. The mean thickness of the conjunctiva and tenon was 302.03 ± 406.76 µm (range 251-1,616 µm). There was a significant negative correlation between the mean thickness of the conjunctiva and tenon and IOP (p = 0.045; confidence interval = -0.558, 0.024). Additionally, there was a significant negative correlation between the mean thickness of the conjunctiva and tenon, and the number of medications used at baseline (p = 0.043; confidence interval = -0.538, 0.051). There was significant negative correlation between the horizontal measurement of the bleb and the use of glaucoma medications (p = 0.017; confidence interval = -0.560, 0.004). A total of 26 patients were determined to have fluid by the examiner (glaucoma expert), and the presence of fluid in AS was confirmed in 19 patients by AS-OCT. Of the 14 patients who were determined to have an absence of fluid, this was confirmed by AS-OCT in 7 patients (Kappa = 0.231; agreement of 65.00%). CONCLUSION: There is fair agreement between glaucoma specialist assessment and AS-OCT assessment in terms of the presence of fluid in trabeculectomy. Our findings highlight the importance of AS-OCT in some patients before deciding upon a new intervention.

PURPOSE: To determine visual field findings in Boston type 1-KPro (BI-KPro) patients without glaucoma. Characterize normal threshold values and global indices using standard automated perimetry and characterize visual field amplitude using Goldmann's manual perimetry. METHODS: This cross-sectional prospective noninterventional study included patients (n=6 patients, 6 eyes) with BI-KPro who had normal optical coherence tomography and fundoscopic evaluation of the optic disc and retina. None had a previous history of glaucoma. Visual acuity, reliable and reproducible standard automated perimetry (24-2 and 30-2), and manual perimetry examinations were obtained from all patients. Each patient answered the National Eye Institute Visual Function Questionnaire, and the results were correlated with visual field indices. RESULTS: The mean visual acuity was 0.35±0.31 logMAR (0.84 to 0.10). All visual fields had good reliability indices. The standard automated perimetry mean deviation values were -7.25±3.63 decibels (dB) and -7.75±3.23 (24-2 and 30-2 values, respectively), whereas pattern SD values were 2.72±0.82 and 3.30±1.13 (24-2 and 30-2, respectively). The manual visual field mean values of the 4 quadrants (superior, temporal, inferior, and nasal), were 39.7±4.5, 61.8±6.2, 54.0±4.3, and 48.2±7.6 degrees, respectively. The authors found a significant correlation between the VFQ-25 indexes of general sight and close-range activities with the values of total deviation at 10 degrees. VFQ-25 peripheral vision indexes also correlated significantly with values of total deviation at 30 degrees (outermost locations in the 30-degree area). CONCLUSIONS: Patients with BI-KPro presented reliable and reproductive visual field measurements. The authors found a consistent reduction in visual field extension and a global sensitivity reduction in these patients. Despite visual field changes, our patients had a good quality of life scores. Overall, these results could be useful to improve early glaucoma diagnosis and to follow-up BI-KPro patients.

The chest wall chondrosarcoma (CWC) is a rare slowly growing primary tumor of the chest wall with an incidence of <0.5 per million person-years. We present the case of a giant CWC that caused a mass effect on the mediastinum, heart, and lung. Large tumors with thoracic structures compression may be life threatening, and its resection and subsequent chest wall reconstruction represent a significant multidisciplinary surgical challenge. In this case, despite the large tumor dimensions, the preoperative planning-sparing key reconstructive options without compromising the tumor resection-allowed a complete en bloc tumor excision of a grade III chondrosarcoma with negative histologic margins. Successful reconstruction of the large full-thickness chest wall defect, with a latissimus dorsi muscle flap and methyl methacrylate incorporated into a polypropylene mesh in a sandwich fashion, was accomplished. Patient recovery was uneventful with good functional and aesthetic outcomes, and no evidence of recurrence at 1.5 years follow-up. This case report illustrates the main clinical, radiological, and histologic features of a CWC while discussing the surgical goals and highlighting the principles for chest wall reconstruction following extensive resection of a large and rare entity.

HTLV-1/2 are transmitted sexually, by whole cell blood products and from mother-to-child (MTC), mainly through breastfeeding. HTLV-1/2 prevalence in pregnant women is high in Rio de Janeiro, however there were no local studies addressing the rate of adverse pregnancy outcomes (APO) and MTC transmission. The aim was to study sociodemographic characteristics which may be associated to HTLV-1/2 infection and describe pregnancy outcomes and MTC transmission in HTLV-1/2-positive women. The cross-sectional study screened 1,628 pregnant women in of Rio de Janeiro (2012-2014) and found 12 asymptomatic carrier mothers (prevalence = 0.74%). Pregnancy outcome information was retrieved from medical records. Sociodemographic characteristics were similar between the positive and negative groups except for maternal age, which was higher in carrier mothers. The incidence of adverse pregnancy outcomes was similar in infected and non-infected patients (p = 0.33), however there was a high rate of premature rupture of membranes (PROM) amid infected mothers (3/12). Multilevel logistic regression found that for each additional year of age, the chance of being HTLV-1/2-positive increased 11% and that having another sexually transmitted infection (STI) increased 9 times the chance of being infected. Carrier mothers had more antenatal visits (OR = 5.26). Among the children of HTLV-1/2-positive mothers there was one fetal death, one infant death and one loss of follow-up. After two years of follow-up there was one case of MTC transmission (1/9). The mother reported breastfeeding for one month only. Knowledge about factors associated to HTLV-1/2 infection, its impact on pregnancy outcomes and the MTC transmission rate is important to guide public health policies on antenatal screening and management.

OBJECTIVE: To synthesize the knowledge produced in studies about the association between violence and STI during pregnancy. METHODS: In this systematic review, we conducted basic activities of identification, compilation, and registration of the trials. The instruments of data collection were studies that investigated, explicitly, relationships between violence, gestation, and STI, from July 2012 to July 2017, using PubMed, Cochrane Library, SciELO, and LILACS. RESULTS: In all, 26 articles were chosen to form the basis of the analysis of this study. The relationship between violence and STI was observed in 22 of the 26 studies, and in eight of them, the violence was practiced during the gestation period. In two studies, there was no evidence of this relationship. In one study, the lack of care for STI was attributed to the unpreparedness of health professionals. Mental disorders were cited as resulting from STI in three articles and in another as a result of violence. One study found more frequent violence against adolescents, while two others cited gestation as a protective factor. CONCLUSIONS: IPV combines characteristics that have a different expression when the woman is in the gestational period. The literature points to a relationship between IPV against women and the presence of STI. The monitoring of pregnancy, whether in the prenatal or postpartum period, offers unique opportunities for the health professional to identify situations of violence and thus provide assistance.

RESUMO OBJETIVO: Sintetizar o conhecimento produzido em estudos sobre a associação entre violência e IST na gestação. MÉTODOS: Nesta revisão sistemática, envolvemos as atividades básicas de identificação, compilação e registro dos ensaios. Os instrumentos de coleta de dados foram os estudos que investigaram, explicitamente, as relações entre violência e gestação e IST, no período de julho de 2012 a julho de 2017, utilizando PubMed, Biblioteca Cochrane, SciELO e Lilacs. RESULTADOS: Ao todo, 26 artigos foram escolhidos para formar a base da análise deste estudo. A relação entre violência e IST foi observada em 22 dos 26 estudos, sendo que em oito deles a violência foi praticada durante o período de gestação. Em dois estudos, não houve evidências dessa relação. Em um estudo, a falta de cuidados com a IST foi atribuída ao despreparo dos profissionais de saúde. Transtornos mentais foram citados como resultantes de IST em três artigos e em outro como resultado de violência. Um estudo encontrou violência mais frequente contra adolescentes, enquanto outros dois citaram a gestação como um fator de proteção. CONCLUSÕES: A VPI combina características que possuem uma expressão diferenciada quando a mulher está no período gestacional. A literatura aponta para uma relação entre a VPI contra as mulheres e a presença de IST. O acompanhamento da gravidez, seja no pré-parto, seja no pós-parto, oferece oportunidades únicas para o profissional de saúde identificar situações de violência e, assim, prestar assistência.

ABSTRACT A 89-year-old Black female with a 6-year history of advanced open-angle glaucoma was referred to the Glaucoma Service of the Ophthalmology Department - Federal University of São Paulo (UNIFESP). Best-corrected visual acuity was 20/400 in the right eye and 20/60 in the left eye. Pseudoexfoliation material was observed at the iris border, angle, and the anterior lens surface. Anterior biomicroscopy revealed exfoliation material forming an evident peripheral zone and a central disc separated by a clear intermediate zone on the anterior lens surface OU. Gonioscopy showed an open-angle Sampaolesis's line and whitish material deposits OU. Fundus examination revealed a cup-to-disc ratio of 1.0 OU with peripapillary atrophy. Genetic analysis for single nucleotide polymorphisms of the lysyl oxidase-like 1 gene linked to exfoliation syndrome identified two such single nucleotide polymorphisms, rs1048661 and rs216524.
RESUMO Uma mulher negra de 89 anos com um histórico de seis anos de glaucoma avançado de ângulo aberto avançado foi encaminhada ao Serviço de Glaucoma do Departamento de Oftalmologia da Universidade Federal de São Paulo (UNIFESP). A acuidade visual melhor corrigida era 20/400 no olho direito e 20/60 no olho esquerdo. Material pseudo-exfoliativo foi observado na borda iriana, ângulo e superfície anterior do cristalino. A biomicroscopia de segmento anterior demonstrou material exfoliativo formando uma zona periférica evidente e um disco central separado por uma zona intermediária livre na cápsula anterior do cristalino. A gonioscopia mostrou uma linha de Sampaolesi de ângulo aberto e depósitos esbranquiçados. O exame de fundo de olho revelou disco óptico com escavação total em ambos os olhos com atrofia peripapilar. A análise genética para polimorfismos de nucleotídeo único do gene semelhante à lysyl oxidase-like 1 ligado à síndrome de esfoliação identificou dois desses polimorfismos de nucleotídeo único, rs1048661 e rs216524.

PURPOSE: To analyze the correlation between structural characteristics of intraorbital optic nerve (ION) and lateral geniculate nucleus (LGN) measured by 3-Tesla magnetic resonance imaging (3T MRI), and the severity of glaucomatous damage. METHODS: In this cross-sectional study, 41 glaucoma patients and 12 age- and sex-matched controls underwent standard automated perimetry (SAP) and frequency doubling technology (FDT) as functional evaluation; optic disc stereophotograph, spectral-domain optical coherence tomography (OCT) and confocal scanning laser tomography as ocular structural evaluation; and 3T MRI. Structure-structure and structure-function correlation were performed using bootstrap resampling method for clustered data. RESULTS: The ION mean diameter and cross-sectional area were different between glaucoma and control groups at 5mm and 10mm (all, p≤0.011) from the globe, but not at 15mm (both, p≥0.067). LGN height was significantly lower in glaucoma group (p = 0.005). OCT rim area and functional parameters (SAP and FDT) correlated significantly with all ION segments, showing stronger correlations at 10 and 15 mm. ION parameters at 10 and 15 mm presented mild-to-moderate correlation with OCT peripapillary nerve fiber layer thickness, and ION at 15mm had mild association with the neuroretinal rim area on stereophotographs. Although LGN height was significantly smaller in glaucoma group (p = 0.005), LGN parameters were not associated with any ocular structural or functional parameter. CONCLUSION: Assessment of central and peripheral nervous systems using 3T MRI confirmed that glaucoma patients had smaller ION dimensions and LGN height compared to the control group. In general, ION dimensions presented mild to moderate correlations with functional and ocular structural parameters. Although ION had significant correlations at any distance from the eye, the ION distal locations correlated better with OCT results and functional parameters. However, LGN parameters were not associated with functional or ocular structural parameters.

A simple method based on sputtering deposition of Pd onto mesoporous SiO2 (SBA-15) was employed to produce supported Pd nanoparticles (NPs) that can be used as hydrogenation catalysts. The use of sputtering deposition eliminates contaminants and avoids additional drawbacks of traditional chemical methods applied to prepare heterogeneous supported metal catalysts. A mechanical resonant stirrer was used to revolve the SBA-15 powder and ensure homogeneous distribution of the Pd NPs over the support. The SBA-15 pores act as templates for Pd NPs and drive nanostructure growth. Consequently, the NPs obtained have the same diameter as that of the SBA-15 channels (~5 nm) and elongated particles are formed as sputtering deposition increases. The SBA-15 supported Pd NPs (Pd NPs/SBA-15) were tested in a probe hydrogenation of cyclohexene reaction to evaluate the catalytic activity of the Pd NPs. Turnover frequency (TOF) of 2000 min-1 were achieved with the lower Pd NPs concentration (0.15 wt%) catalyst.

OBJECTIVE: To evaluate retinal changes in patients who underwent solid organ or bone marrow transplantation. METHODS: A retrospective analysis of medical records of patients evaluated from February 2009 to December 2016. All patients included underwent funduscopy. Clinical and demographic data regarding transplantation and ophthalmological changes were collected. RESULTS: A total of 126 patients were analyzed; of these, 108 underwent transplantation and 18 were in the waiting list. Transplantation modalities were heart, lung, kidney, liver, pancreas, combined pancreas and kidney and bone marrow transplantation. The main pre-transplantation comorbidities were diabetes and arterial hypertension. Of the 108 transplanted patients, 82 (76%) had retinal changes. All patients who underwent pancreas or combined pancreas and kidney transplantation had diabetic retinopathy. The main retinal changes found were diabetic retinopathy, hypertensive retinopathy, retinal vascular occlusions, chorioretinal infections and central serous chorioretinopathy. CONCLUSION: Retinal changes were either related to preexisting conditions, mainly diabetic retinopathy, or developed postoperatively as a complication of the surgical procedure, or as an infection related to the immunosuppressive status, or due to drug toxicity. These patients may present with complex ophthalmological changes and should be carefully evaluated prior to surgery and further followed by an ophthalmologist skilled in the management of diabetic retinopathy and posterior pole infections. OBJETIVO: Analisar as alterações retinianas de pacientes submetidos a transplantes de órgãos sólidos ou de medula óssea. MÉTODOS: Análise de prontuário dos pacientes avaliados no período de fevereiro de 2009 a dezembro de 2016. Todos os pacientes incluídos foram submetidos à avaliação fundoscópica. Foram coletados dados demográficos e clínicos, referentes ao transplante e às alterações oftalmológicas encontradas. RESULTADOS: Foram avaliados 126 pacientes, sendo 108 submetidos a transplantes e 18 que aguardavam o procedimento. Foram avaliados pacientes submetidos a transplantes de coração, pulmão, rim, fígado, pâncreas, pâncreas-rim e medula óssea. As principais comorbidades pré-transplante foram diabetes e hipertensão arterial. Dos 108 pacientes transplantados, 82 (76%) apresentaram alterações retinianas. Todos os pacientes submetidos ao transplante de pâncreas ou pâncreas-rim apresentaram alterações retinianas relacionadas ao diabetes. As principais alterações retinianas detectadas foram retinopatia diabética, retinopatia hipertensiva, oclusões vasculares retinianas, infecções coriorretinianas e coriorretinopatia serosa central. CONCLUSÃO: As alterações retinianas estavam relacionadas a doenças preexistentes, principalmente à retinopatia diabética, ou surgiram após o transplante, como complicação do procedimento cirúrgico, ou como complicação infecciosa associada à imunossupressão, ou ainda por toxicidade medicamentosa. Tais pacientes podem apresentar alterações oculares complexas, devendo ser submetidos à avaliação retiniana pré-operatória cuidadosa e ao acompanhamento pós-operatório por oftalmologista especializado no manejo da retinopatia diabética e de doenças infecciosas do segmento posterior ocular.
