RESUMO

La neurorretinopatía macular aguda es una condición rara con patogenia microvascular. Se presenta con un inicio agudo con escotomas paracentrales correspondientes a lesiones paramaculares evidentes. Los avances en las imágenes multimodales permitieron caracterizar este trastorno de retina y crear nuevos conceptos. Serraf, en el 2013, identificó dos formas por medio de la tomografía de coherencia óptica dominio espectral: el tipo 1 conocido como maculopatía paracentral aguda media en la cual se observa una banda hiperreflectiva en la capa nuclear interna, y el tipo 2 en el cual la banda hiperreflectiva se ubica en la capa nuclear externa, que involucra la zona elipsoide y la zona de interdigitación con el epitelio pigmentario de la retina. Hasta el momento no existe cura; pero se puede actuar sobre los factores de riesgo. Por ser una condición rara y por no existir reportes hasta el momento en Cuba es que se presentan a continuación dos pacientes con cuadros clínicos similares de estas dos variantes; concluyendo la importancia que presentan las imágenes multimodales como medio auxiliar diagnóstico(AU)


Acute macular neuroretinopathy is a rare condition with complex pathogenesis and microvascular cause. It appears with acute onset, with paracentral scotomas corresponding to obvious paramacular lesions. Advances in multimodal imaging made it possible to characterize this retinal disorder and to create new concepts. Serraf, in 2013, identified two forms by spectral domain optical coherence tomography: type 1, known as paracentral acute middle maculopathy, in which a hyperreflective band is observed in the inner nuclear layer; and type 2, in which the hyperreflective band is located in the outer nuclear layer, involving the ellipsoid zone and the zone of interdigitation with the retinal pigment epithelium. Up to this moment, there is no cure; but it is possible to act on the risk factors. Because it is a rare condition and because there are no reports so far in Cuba, two patients with similar clinical pictures of these two variants are presented; concluding the importance of multimodal images as an auxiliary diagnostic tool(AU)

RESUMO

Introducción: El síndrome de Vogt-Koyanagi-Harada pertenece a los síndromes uveomeníngeos y es una de las principales enfermedades que amenazan la visión. Se caracteriza por una uveítis bilateral que se asocia frecuentemente con manifestaciones neurológicas, auditivas y tegumentarias. Recientemente un fenotipo particular de engrosamiento macular se ha descrito como desprendimiento bacilar asociado a esta enfermedad. Objetivo: Describir el desprendimiento bacilar de la retina mediante la tomografía de coherencia óptica de dominio espectral en un caso de Vogt Koyanagi Harada en fase uveítica. Presentación de caso: Paciente femenina de 46 años de edad atendida en el Instituto Cubano de Oftalmología "Ramón Pando Ferrer" con disminución de agudeza visual en ambos ojos y panuveitis bilateral. Fue diagnosticada con síndrome de Vogt-Koyanagi-Harada en su fase uveítica aguda con presencia de manifestaciones neurológicas y desprendimiento de la capa bacilar de la retina identificado mediante la tomografía de coherencia óptica de dominio espectral. Conclusiones: El síndrome de Vogt-Koyanagi-Harada aguda y el desprendimiento bacilar de la capa de la retina pueden diferenciarse de otros signos mediante la tomografía de coherencia óptica de dominio espectral. Su desaparición pudiera tener una relación con la mejoría de la agudeza visual(AU)


Introduction: Vogt-Koyanagi-Harada syndrome belongs to the uveomeningeal syndromes and is one of the major vision-threatening diseases. It is characterized by bilateral uveitis, which is frequently associated with neurological, auditory and integumentary manifestations. Recently a particular phenotype of macular thickening has been described as bacillary detachment associated with this disease. Objective: To describe bacillary retinal detachment using spectral domain optical coherence tomography in a case of Vogt Koyanagi Harada in uveitic phase. Case presentation: 46-year-old female patient attended at the Cuban Institute of Ophthalmology "Ramón Pando Ferrer" with decreased visual acuity in both eyes and bilateral panuveitis. She was diagnosed with Vogt-Koyanagi-Harada syndrome in its acute uveitic phase with presence of neurological manifestations and detachment of the bacillary layer of the retina identified by spectral domain optical coherence tomography. Conclusions: Acute Vogt-Koyanagi-Harada syndrome and bacillary retinal layer detachment can be differentiated from other signs using spectral-domain optical coherence tomography. Their disappearance could be related to the improvement of visual acuity(AU)

RESUMO

BACKGROUND: Cataract surgery with multifocal IOLs could give patients good vision and great satisfaction, at the same time generating high expectations; therefore, its precise indication is essential if we are to reach our goal. The use of optical coherence tomography may be a valuable tool in the screening of macular diseases, which often cannot be detected in routine clinical examinations. This study evaluates the benefit of including spectral domain optical coherence tomography (SD-OCT) in routine preoperative cataract surgery protocols for better case selection in multifocal IOLs. METHODS: Observational and retrospective clinical study that includes patients with an indication for multifocal IOL implantation who underwent retinal fundus exam and SD-OCT examination between 2018 and 2019. The clinical examination with ophthalmoscopy and SD-OCT imaging results were evaluated to observe their influence on the final choice of the lens implanted lens in cataract surgery. RESULTS: 405 eyes from 207 patients with multifocal IOL indication were included. It was found that 220 (54.2%) of all indicated multifocal or trifocal IOLs were in fact implanted. The most important reason for not implanting the indicated IOL was financial, in 116 (59.46%) eyes. The second cause were retinal abnormalities detected by SD-OCT, 63 eyes (15.6%). Those abnormalities included dry age-related macular degeneration (AMD) (50.7%), neovascular AMD (3.1%), vitreomacular adhesion (11.1%), diabetic macular edema (3.1%), epiretinal membrane (ERM) (25.3%) and other macular abnormalities (6.3%). Of the 63 eyes with an abnormal SD-OCT result, 44 (69.8%) were also identified by fundus examination. Nineteen (30.2%) eyes had abnormalities detected only by SD-OCT imaging with a normal clinical exam. CONCLUSIONS: Routine use of SD-OCT imaging may help diagnose pre-existing macular pathologies not identified by clinical exam, helping both physicians and patients choose the ideal IOL individually and has the potential to prevent unsatisfactory functional results.

RESUMO

BACKGROUND: To describe the spontaneous closure of a degenerative lamellar macular hole with epiretinal proliferation (LHEP) as documented with tracked spectral domain optical coherence tomography (SD-OCT). CASE PRESENTATION: A 54-years-old diabetic female patient presented with progressive vision loss in the left eye. SD-OCT illustrated LHEP associated with cystic fluid in the outer nuclear layer. Sequentially tracked SD-OCT showed progressive closure of the degenerative lamellar macular hole and resolution of the CME over almost 4 years, in the absence of any surgical intervention. DISCUSSION/CONCLUSION: LHEP may represent a specialized form of degenerative epiretinal membrane associated with Muller cell activation. Spontaneous degenerative LMH closure may rarely occur with these lesion types, in the absence of surgical intervention, possibly due to Muller cell proliferation preceded by PVD.

RESUMO

PURPOSE: To present a case of stellate nonhereditary idiopathic foveomacular retinoschisis (SNIFR) resolution associated with vitreomacular adherence (VMA) release and propose a potential contributing association between SNIFR and vitreomacular interactions. OBSERVATIONS: A 67-year-old female patient was diagnosed and followed for SNIFR in OD with spectral-domain optical coherence tomography (SD-OCT) scans at presentation and subsequent visits at 3, 6, 16 and 22 months. VMA and foveomacular retinoschisis remained unchanged on SD-OCT during the first 6 months of the follow-up. At 16-month follow-up visit, SD-OCT revealed VMA release and an important improvement of the macular schisis. At 22 months of follow-up, SNIFR cavities completely resolved in the presence of posterior hyaloid separation from the macular area without any adjunct treatment. The authors could not identify any other possible cause to justify the resolution of SNIFR other than VMA release in this case. Patient did not undergo any treatment for OD other than phacoemulsification 3 months after initial visit. CONCLUSION: The present case illustrates with SD-OCT scans a possible association between SNIFR resolution and VMA release, highlighting a potential tractional component of the posterior vitreous on the internal limiting membrane and consequent glial cells stretching with schisis formation.

RESUMO

PURPOSE: To report normal values of macular and choroidal thickness obtained from a healthy Hispanic population using Optovue (Optovue Inc, Freemont CA, USA) spectral domain optical coherence tomography (SD-OCT). DESIGN: Observational, cross-sectional, correlation study. METHODS: A total of 290 eyes (145 healthy subjects) were included; 69% of subjects were female. The median age was 39 ± 29 years (IQR), with a range between 18 and 89 years. The study sample was stratified into three age groups: Group 1, 18-40 years (50.3%), Group 2, 41-60 years (30.7%), and Group 3, older than 61 years (19%). Central macular, perifoveal (inner quadrants), and parafoveal (outer quadrants) thicknesses were estimated. In addition, central and peripheral choroidal thicknesses were estimated. Data analysis was performed to calculate the standardized mean difference according to the variance (Student's t-test) and its differences with Epidat 4.1. RESULTS: Median macular central thickness was 250 ±30 µm (IQR) with Optovue. Median central choroidal thickness was 263 ± 48 µm (IQR). Median central choroidal thickness was greater than mean peripheral thickness. Macular evaluation showed a statistically significant difference in central, perifoveal, and parafoveal thicknesses, with lower values being recorded for the study sample compared with the manufacturer's data. CONCLUSIONS: SD-OCT has become a useful tool to obtain high-resolution images of the macula and choroid. This method allows precise assessment of the retinal and choroidal layers to diagnose and follow up posterior segment diseases. We are reporting normal cut-off values of macular and choroidal thicknesses in healthy Hispanic subjects evaluated with Optovue SD-OCT as new diagnostic normal parameters for research and clinical activities.

RESUMO

PURPOSE: To describe pertinent imaging studies and clinical features of a torpedo maculopathy presumably associated with congenital Zika syndrome. OBSERVATION: A 23-month-old child, with no prematurity or microcephaly at birth, was examined in the Ophthalmology department of the University Hospital of Fort-de-France (Martinique, French West Indies), as part of a systematic screening of malformations in children suspected of maternal-fetal exposure to Zika virus. Zika infection was confirmed in the mother's serum by Reverse Transcriptase Polymerase Chain Reaction during the third trimester of pregnancy. Fundus examination found a unilateral hypopigmented retinal lesion, temporal to the macula, with an apex pointing to the fovea. Explorations in spectral-domain optical coherence tomography showed a subretinal cleft with broadening and attenuation of the interdigitation zone, elevation of the outer limiting membrane and the ellipsoid zone, without thinning of the outer retinal layers. CONCLUSION AND IMPORTANCE: There is a proven risk of congenital eye defects after Zika infection during pregnancy. We report here the first case of torpedo maculopathy without microcephaly, in a child suspected of maternal-fetal exposure to Zika.

RESUMO

PURPOSE: To describe the long-term outcome of a patient with multifocal choroiditis, who underwent surgical removal of a type 2 choroidal neovascular membrane employing 23 G pars plana vitrectomy. OBSERVATIONS: A 50-year-old man was treated with 3 monthly intravitreal bevacizumab injections, but despite treatment, visual acuity continued to worsen from 20/40 to 20/100, and bleeding was not receding. A minimal invasive pars plana vitrectomy was performed for surgical removal of the neovascular complex without any complicating incident. Subsequent visual acuity was 20/25 for more than eleven years. CONCLUSIONS AND IMPORTANCE: Surgical removal of choroidal neovascular membranes employing minimal invasive surgery in addition to anti-VEGF therapy, and OCT evaluation can be a viable approach for selected cases of juxtafoveal type 2 CNV.

RESUMO

PURPOSE: To describe the spectral domain optical coherence tomography (SD-OCT) features of a punctate inner retinitis, a rare ocular manifestation of syphilis, in an HIV positive adult patient. OBSERVATIONS: In the right eye, SD-OCT images during the active period showed hyperreflectivity of the full thickness of the inner retina, precluding the individualization of the layers. In addition, multifocal areas with higher hyperreflectivity were identified within the affected retina. Once the lesion became inactive, SD-OCT images revealed inner retina layers atrophy, disruption of the ellipsoid layer, and multifocal damage to the retinal pigment epithelium layer. CONCLUSION AND IMPORTANCE: Punctate inner retinitis affects the full thickness retina, leading to severe retinal damage, along with multifocal damage of the retinal pigment epithelium. The multifocal white retinal lesions observed within the affected retinal area correlated with the presence of intense hyperreflective dots within the retina showed by SD-OCT. These lesions are deeper than was described in other reports.

RESUMO

PURPOSE: The aim of this study was to evaluate the correlations between fundus autofluorescence and morphologic parameters as well as visual function in patients with diabetic macular oedema treated with intravitreal ziv-aflibercept. METHODS: A total of 34 eyes of 20 patients with untreated diabetic macular oedema received an intravitreal injection of ziv-aflibercept at baseline, and 1 and 2 months later. The baseline, 1-month, and two-month best corrected visual acuity determination, contrast sensitivity, spectral domain optical coherence tomography, mean central macular thickness, mean macular cube volume, mean macular cube average thickness, and fundus autofluorescence (decreased, normal, or increased; and single or multiple spots) were measured. Correlation analysis with a determination of Spearman's rank correlation coefficient, regression analysis, agreement between investigators, and Friedman's test were used for statistical analyses. RESULTS: A direct correlation was observed between baseline fundus autofluorescence and macular cube average thickness at 1 month (r = 0.51, p = 0.020) and between fundus autofluorescence at 1 month and baseline macular cube average thickness (r = 0.50, p = 0.021). Regression analysis showed a coefficient of determination of 0.29 (p = 0.016) between baseline fundus autofluorescence and macular cube average thickness at 1 month. CONCLUSION: In patients with diabetic macular oedema, the pretreatment baseline degree of foveal fundus autofluorescence might be helpful in predicting macular cube average thickness in patients undergoing treatment with intravitreal ziv-aflibercept in the short term.

RESUMO

PURPOSE: To evaluate the expansion of the hyperautofluorescent ring and the retinal structure changes over time in cone-rod dystrophy (CRD) patients, using fundus autofluorescence (FAF) and spectral-domain optical coherence tomography (SD-OCT). METHODS: Retrospective case series study. Six eyes of three CRD patients with a parafoveal hyperautofluorescent ring were studied. The diagnosis of CRD was established by the presence of the implicit time shift at 30-Hz flicker and prevalent decrease of photopic over scotopic responses on electroretinography. External and internal ring expansion was evaluated by measurements of its area at baseline and at 24-month follow-up using FAF. SD-OCT analyzed the retinal structure of the ring and the length of devoid ellipsoid zone (EZ) was measured over time. RESULTS: The mean age of study patients was 21 years old and the mean baseline visual acuity was 20/200. The external and internal FAF rings involving the fovea were identified in all study eyes. SD-OCT showed a normal retinal structure outside the ring. At the transitional zone of the ring, disorganization of both EZ and external limiting membrane (ELM) was observed. Inside the hyperautofluorescent ring, EZ and ELM were not identified. At 24-month follow-up examination, the mean % area increase of external and internal rings were 18.32% and 20.42%, respectively, and was concordant with the EZ band defect length enlargement. CONCLUSION: Progressive expansion of hyperautofluorescent macular ring with a correspondent EZ band defect enlargement was observed over time in CRD patients.

RESUMO

PURPOSE: To report the fundus manifestations and spectral-domain optical coherence tomographic (SD-OCT) features of dengue fever presenting as Purtscher-like retinopathy. METHODS: Retrospective review of two cases of dengue fever. RESULTS: Color fundus photograph revealed the presence of cotton-wool spots in a Purtscher-like configuration in the posterior pole of all study eyes. SD-OCT demonstrated increased reflectivity signal in the inner retinal layers, and after a variable follow-up period, there was complete disappearance of cotton-wool spots and persistence of the hyperreflectivity signal. CONCLUSION: We report two unique cases of dengue fever associated with retinal lesions in a configuration of Purtscher-like retinopathy.

RESUMO

El agujero macular idiopático es causado por fuerzas traccionales tangenciales, asociadas al desprendimiento de vítreo posterior perifoveal degenerativo, cuyo tratamiento es actualmente quirúrgico, en pacientes con estadio 2, 3 o 4. Presentamos un caso clínico donde se describen las alteraciones anatómicas y funcionales producidas por el edema macular quístico posterior a la cirugía de agujero macular idiopático estadio 3, y que luego de un cierre exitoso anatómico y funcional de este comenzó con edema macular quístico recurrente, sin reapertura del agujero macular; respondió al uso de esteroides locales recomendable en estos casos y logró mejorar los resultados visuales iniciales posquirúrgicos(AU)


The idiopathic macular hole is caused by tangential tensile forces associated with degenerative perifoveal posterior vitreous detachment, and the treatment is currently surgical in stage 2, 3 or 4 patients. We presented a clinical case in which we described the anatomical and functional alterations produced by cyst macular edema after idiopathic macular hole surgery in a stage 3 patient. After a successful anatomical and functional closure, it began with cystic macular edema; and the reopening of the macular hole did not occur, responding to the use of recommended local steroids for these cases, and finally the initial visual results after surgery were improved(AU)

RESUMO

PURPOSE: The aim of this study was to compare physician preferences regarding the commercially available spectral-domain (SD) optical coherence tomography angiography (OCTA) and swept-source (SS) OCTA prototype device. DESIGN: Comparative analysis of diagnostic instruments was performed. PATIENTS AND METHODS: Subjects at the University of Washington Eye Institute and Harborview Medical Center were prospectively recruited and imaged with the Zeiss SD OCTA (HD-5000, Angioplex) and Zeiss SS OCTA (Plex Elite, Everest) devices on the same day. The study included 10 eyes from 10 subjects diagnosed with a retinal/choroidal disease. Deidentified images were compiled into a survey and sent to retina specialists in various countries. The survey presented masked SD and SS images of each eye for each retinal sublayer side by side. Respondents were asked about their image preference and impact on clinical management. A priori and post hoc preferences for SD vs SS were collected. RESULTS: Fifty-four retina specialists responded to the survey. Median years in practice was 3.00 (interquartile range [IQR] 1.50-17.00). At baseline, 23 (48%) physicians owned an OCTA machine. The majority of physician responses showed a preference for the SS over SD OCTA, independent of the retinal pathology shown (n=454 overall responses, 74%). Nevertheless, the majority indicated that both SD and SS would be equally valuable in informing clinical decisions (n=374 overall responses, 61%). CONCLUSION: These findings indicate that the majority of retina specialists surveyed prefer SS over SD OCTA based on image quality, regardless of the retinal pathology shown. Regarding the clinical utility of each modality, the majority of physicians perceive SD and SS as equally effective.

RESUMO

BACKGROUND: Retrospective review of one acute syphilitic posterior placoid chorioretinitis (ASPPC) case with serological evidence of syphilis who had ocular signs and symptoms not attributable to other diseases. Enface and spectral-domain optical coherence tomographySD-OCT were analyzed at the time of presentation and at 1-month visit following initiation of treatment. The study patient underwent standard treatment for neurosyphilis. RESULTS: Ophthalmic examination and imaging studies were consistent with the diagnosis of ASPPC. The patient age was 33 year-old and the baseline visual acuity was 20/400 and 20/80 in the right and left eyes, respectively. At presentation, SD-OCT scans showed disruption and loss of the ellipsoid zone (EZ), small nodular elevations on retinal pigment epithelium (RPE) and punctate hyperreflectivity in the choroid. Enface OCT at the level of RPE and EZ demonstrated multiple hyperreflective dot-like lesions simmetrically distributed within the macular area. These dot-like lesions corresponded to the small nodular elevations on RPE and to disruption/loss of EZ observed with SD-OCT. One month after neurosyphilis therapy, the visual acuity improved and the outer retinal changes partially reversed in both eyes. CONCLUSIONS: We report the outer retinal findings and its correlation using both en-face and SD-OCT in a patient with ASPPC. En-face OCT imaging provides a more precise outer retinal layers analyses allowing a better understanding of the ASPPC pathophysiology.

Resultado: La angiografía por tomografía de coherencia óptica identificó cambios estructurales y zonas de isquemia en la macula de un paciente asintomático no identificados en la angiografía fluoresceinica asociado a adelgazamiento de las capas retinianas externas. Conclusión: El presente reporte de caso demuestra la ventaja que posee la angiografía por tomografía de coherencia óptica sobre la angiografía fluoresceinica para identificar cambios compatibles con vasculopatía isquémica a nivel del plexo vascular profundo en la macula de en un paciente con manifestaciones tempranas de retinopatía por anemia de células en la periferia. Evidencia que las alteraciones vasculares podrían causar adelgazamiento de las capas retinianas externas.


Objective: To report a case of sickle cell retinopathy using optical coherence tomography angiography. Design: Case Report. Methods: Case report of an asymptomatic male patient with type SS sickle cell anemia. Results: Optical coherence angiography identified structural changes and nonperfusion in the macula of an asymptomatic patient that were not identified with fluorescein angiography associated to outer layer retinal thinning. Conclusion: The present report demonstrates the advantage of optical coherence tomography angiography over fluorescein angiography to identify changes compatible with ischemic vasculopathy in the deep capillary plexus of the macula of patient with early signs of sickle cell retinopathy at the periphery. It provides evidence that the ischemic vascular alterations aff ect the deep capillary plexus and could cause outer retinal thinning.

RESUMO

BACKGROUND: Outer retinal tubulations (ORTs) are branching tubular structures located in the outer nuclear layer of the retina. The goal of this study is to determine the prevalence of ORTs observed in eyes with choroidal neovascularization (CNV) undergoing treatment with anti-angiogenic intravitreous injection (IVI) with anti-VEGF (vascular endothelial growth factor) at the Ophthalmology Department of a tertiary hospital in São Paulo, Brazil. METHODS: This is a descriptive study based on medical charts and Spectral-domain Optical Coherence Tomography (Sd-OCT) scans of 142 patients (158 eyes) treated between 2012 and 2014 with IVI of anti-VEGF for CNV. The patients' data was analysed according to age, gender, pathology, presence of ORTs, and best corrected visual acuity (BCVA). Patients with and without ORTs were compared according to the last BCVA obtained using Chi square corrected by the Yates factor. RESULTS: ORTs were found in a total of 40 out of 158 eyes (25.31 %) with CNV; in 33 out of 119 eyes (27.7 %) with neovascular age-related macular disease (AMD); in 5 out of 8 eyes (62.5 %) with neovascular angioid streaks; and in 2 out of 12 eyes (16.67 %) with myopic neovascular membranes. Most patients with ORTs had BCVA worse than 20/200, significantly worse BCVA than patients without ORTs. CONCLUSIONS: Recent studies have considered that the presence of ORTs is indicative of a photoreceptor degeneration process and may represent a final stage of multiple retinal degenerative pathologies. The prevalence of ORTs in eyes with CNV has not been well described, especially when considering the Brazilian population treated in a public health care system. In our study, ORTs were observed in only three different pathologies: neovascular AMD, neovascular angioid streaks and myopic neovascular membranes. The correct recognition of ORTs is fundamental for its differentiation from intraretinal cysts, for the latter is related to the activity of neovascular diseases, and usually guides anti-angiogenic therapy. We conclude that ORTs have a high prevalence in the population studied, and their correct identification presents relevant therapeutic implications.

RESUMO

Detection of progression and measurement of rates of change is at the core of glaucoma management, and the use of Spectral Domain Optical Coherence Tomography (SD-OCT) has significantly improved our ability to evaluate change in the disease. In this review, we critically assess the existing literature on the use of SD-OCT for detecting glaucoma progression and estimating rates of change. We discuss aspects related to the reproducibility of measurements, their accuracy to detect longitudinal change over time, and the effect of aging on the ability to detect progression. In addition, we discuss recent studies evaluating the use of combined structure and function approaches to improve detection of glaucoma progression.
