RESUMO
PURPOSE: This study aimed to investigate the correlation between serum vitamin D levels and disease activity in patients with noninfectious uveitis. METHODS: We conducted a prospective case-control study, assessing 51 patients with noninfectious uveitis, categorized into active (n=22) and inactive (n=29) groups, along with 51 healthy controls. Serum 25-hydroxy vitamin D [25(OH)D] levels were measured. The uveitis group also completed a questionnaire regarding sunlight exposure habits and vitamin D supplementation. RESULTS: Patients with inflammation-related uveitis exhibited low serum 25(OH)D levels in 68% of cases. The median 25(OH)D level in patients with active uveitis was 17.8 ng/mL (interquartile range [IQR], 15-21 ng/mL), significantly lower compared to the 31.7 ng/mL (IQR, 25-39 ng/mL) in patients with inactive uveitis (p<0.001) and the 27 ng/mL (IQR, 23-31 ng/mL) in the Control Group (p<0.001). Significantly, nearly all patients with uveitis taking vitamin D supplementation were in the Inactive Group (p<0.005). Moreover, reduced sunlight exposure was associated with active uveitis (p<0.003). Furthermore, patients with 25(OH)D levels below 20 ng/mL had ten times higher odds of developing active uveitis (p=0.001). CONCLUSIONS: This study revealed a prevalent 25(OH)D deficiency among patients with noninfectious uveitis and suggested a link between low 25(OH)D levels and disease activity. To prevent future episodes of intraocular inflammation, vitamin D supplementation and controlled sunlight exposure could be viable options.

RESUMO
ABSTRACT Purpose: The aim of this study was to describe the epidemiological profile of uveitis cases treated at University Hospital Clementino Fraga Filho and to identify the presentation pattern of intraocular inflammation on the basis of clinical, anatomical, etiological, and demographic criteria. Methods: A retrospective study was conducted using data from the medical records of 408 patients with active disease who attended the ophthalmology service between March and October 2018. Age, sex, visual acuity at the time of diagnosis, anatomical and etiological diagnoses, the clinical aspect, and the main symptoms reported during anamnesis were described. Results: Of the 408 patients in the study, 52% were male and 48% were female. The patients' mean age was 42 years, and most (84%) were between 19 and 64 years old. Anterior uveitis was observed in 37.75% of the patients; posterior uveitis, in 49.75%; panuveitis, in 4.66%; and intermediate uveitis, in 3.43%. Only 18 patients (4.41%) presented with scleritis. Of the 390 patients with anatomical classifications, 76% had known etiologies, with the most prevalent diagnoses being toxoplasmosis (35.4%), followed by juvenile idiopathic arthritis (6.4%), ankylosing spondylitis (5.9%), and syphilis (4.9%). Infectious uveitis corresponded to 49.7% of the patients, while 26.6% of the cases were of noninfectious origin. Anterior uveitis had the highest number of cases classified as idiopathic (49.4%). In the cases of posterior uveitis, the etiology was established 94% of the time. The most frequent symptoms were ocular pain (71.8%) and blurring vision (56.8%). Conclusions: The present study confirmed the historical importance of infectious uveitis in our population, especially ocular toxoplasmosis. Uveitis appears to have no predilection for sex but mainly affects young people of working age, thus generating social and economic consequences. Despite the evolution of diagnostic methods, idiopathic uveitis remains one of the major etiologies. Epidemiological studies point to different presentation patterns of uveitis in different populations, but these may reflect the distinct characteristics of each institution.
RESUMO Objetivo: Descrever o perfil epidemiológico das uveítes atendidas no Hospital Universitário Clementino Fraga Filho - UFRJ. Identificando o padrão de apresentação da inflamação intraocular a partir de critérios clínicos, anatômicos, etiológicos e demográficos. Métodos: Estudo retrospectivo, com base em prontuários de 408 pacientes com doença ativa, atendidos no serviço de oftalmologia no período de março a outubro de 2018. Foram descritos a idade, sexo, acuidade visual no momento do diagnóstico, diagnóstico anatômico e etiológico, aspecto clínico, além dos principais sintomas relatados durante a anamnese. Resultados: Dos 408 pacientes do estudo, 52% eram do sexo masculino e 48% do feminino. A idade média dos pacientes foi de 42 anos, a maioria (84%) entre 19 e 64 anos. Uveíte anterior foi observada em 37,75% dos pacientes, uveíte posterior em 49,75%, panuveíte em 4,66% e uveíte intermediária em 3,43%; apenas 18 pacientes (4,41%) apresentaram diagnóstico de esclerite. Dos 390 pacientes com classificação anatômica, a etiologia foi determinada em 76% deles, com os diagnósticos mais prevalentes sendo Toxoplasmose (35,4%), artrite idiopática juvenil (6,4%), espondilite anquilosante (5,9%) e sífilis (4,9%). ) A uveíte infecciosa correspondeu a 49,7% desses pacientes, enquanto 26,6% eram de origem não infecciosa. A uveíte anterior teve o maior número de casos classificados como idiopáticos (49,4%), enquanto a uveíte posterior teve a etiologia estabelecida em 94% das vezes. Os sintomas mais frequentes foram dor ocular (71,8%) e visão embaçada (56,8%). Conclusões: O presente estudo confirmou a importância histórica da uveíte infecciosa em nossa população, principalmente a toxoplasmose ocular. As uveítes parecem não ter predileção por sexo, mas afetam principalmente jovens em idade ativa, gerando consequências sociais e econômicas. Apesar da evolução nos métodos diagnósticos, a uveíte idiopática continua sendo uma das principais causas. Estudos epidemiológicos apontam para diferentes padrões de uveíte nas populações, estes podem refletir características particulares de cada instituição.

Purpose: To evaluate and establishe the number of patients with ocular manifestations in the early phase of systemic COVID-19 infection.Methods: A cross-sectional study was performed in a COVID-19 referral center regarding ocular findings in patients with COVID-19 in the first few days of the disease. The patients were submitted to a clinical examination, an ophthalmic exam and a RT-PCR for SARS-COV-2.Results: Out of 1740 patients, we reported 108 patients with ocular manifestations. Forty-nine with markedly conjunctivitis had conjunctival swab positive for SARS-COV-2, four of them developed keratitis. There were mostly no evidence of retinopathy nor decrease in visual acuity. They had no marked clinical symptoms, which can contribute and demonstrate that the virus may cause ocular disease as an only finding or in the very early stage of the infection.Conclusion: Patients were in the first days of COVID-19 infection, presented ocular manifestations suggested to be related to the virus and need to be aware of the pathways of transmissions.

ABSTRACT This study aimed to analyze the anterior lens capsule specimens from both eyes of a patient with systemic sclerosis and compare them to the eyes of a control patient. No significant differences between systemic sclerosis and control eyes were observed in the results from the hematoxylin-eosin and picrosirius staining. In the samples obtained from both systemic sclerosis and control eyes, there were expressions of caspase, a molecule expressed in cell death by apoptosis. Heparanase was overexpressed in the systemic sclerosis sample compared to the control sample. Therefore, the anterior lens capsule of the patient with systemic sclerosis is probably affected by the disease since it showed marked expression of heparanase 1.(AU)
RESUMO Analisamos as amostras das cápsulas anteriores do cristalino de uma paciente com esclerose sistêmica e comparamos com as de um paciente controle. Não foram observadas diferenças significativas entre esclerose sistêmica e controle nos resultados da coloração com hematoxilina-eosina e picrosirius. Nas amostras obtidas da esclerose sistêmica e do controle, obtivemos expressão de caspase, uma molécula expressa na morte celular por apoptose. A heparinase foi expressa de forma mais marcante na amostra de esclerose sistêmica quando comparada ao controle. Portanto, a cápsula anterior do cristalino da paciente com esclerose sistêmica provavelmente foi afetada pela doença, uma vez que mostrou expressão aumentada de heparinase 1.(AU)

RESUMO Este trabalho visou evidenciar a importância da detecção precoce da coroidite interna punctata e destacar sua fisiopatologia inflamatória e possíveis diagnósticos diferenciais dentro das white dot syndromes. O destaque foi dado principalmente à coroidite multifocal e à panuveíte, ao se demonstrar sua epidemiologia peculiar em mulheres jovens, caracterizar sua apresentação clínica típica na fundoscopia e explorar as vantagens e as desvantagens de realizar os exames complementares que fazem parte da análise multimodal útil para o diagnóstico (especialmente a angiografia fluoresceínica, a tomografia de coerência óptica e a indocianina verde). Descreve-se o caso de uma mulher de 28 anos diagnosticada com coroidite interna punctata com membrana neovascular coroidal em olho direito. O tratamento foi realizado com injeção intravítrea de aflibercepte e corticoterapia sistêmica 1mg/kg ao dia. Este relato é importante por permitir debater o manejo da coroidite interna punctata durante a gestação e a decisão de realizar o tratamento mediante uma diversidade de opções terapêuticas.
ABSTRACT This work aimed to demonstrate the importance of early detection of punctate inner choroidopathy, highlighting the pathophysiology of inflammation and the differential diagnoses among white dot syndromes. Special attention was given to multifocal choroiditis and panuveitis, by demonstrating the peculiar epidemiology in young women, characterizing the typical clinical presentation in ophthalmoscopy, and exploring the advantages and disadvantages of performing the complementary examinations, which are part of the multimodal analysis useful for diagnosis (particularly fluorescein angiography, optical coherence tomography, and indocyanine green). We report the case of a 28-year-old female, diagnosed as punctate inner choroidopathy with choroidal [N.T. no título aparece subretinal = subrretiniana] neovascular membrane in the right eye. She was treated with intravitreal injection of aflibercept and systemic corticosteroid 1 mg/kg/day. This case report is important for addressing the management of punctate inner choroidopathy during pregnancy, and the decision to carry out treatment considering diverse therapeutic options.

Resumo Apresentamos um caso de neurosífilis em um homem jovem, com queixa de baixa acuidade visual (BAV) em olho esquerdo. Cursou com lesões eritemato-descamativas nas palmas das mãos, plantas dos pés e úlceras orais, sem lesões genitais. O exame oftalmológico revelou arterite em arcada nasal superior no olho afetado. Apresentou VDRL (1:4096) e FTA-Abs positivos. O exame do líquor cefalorraquidiano foi negativo. O tratamento foi realizado com ceftriaxona 2g/ dia por 14 dias, associado à prednisona 0,5mg/kg oral 48h após início do antibiótico. Após 15 dias de tratamento, houve melhora da AV, regressão da vasculite e redução da titulação do VDRL para 1:128.
Abstract We present a case of neurosyphilis in a young man with a complaint of low visual acuity in the left eye. He had erythematous-scaly lesions on the palms of the hands, soles of the feet and oral ulcers, without genital lesions. The ophthalmic examination revealed arteritis in the upper nasal arcade in the affected eye. He presented VDRL (1: 4096) and FTA-Abs positive. The cerebrospinal fluid cerebrospinal fluid test was negative. The treatment was performed with ceftriaxone 2g / day for 14 days, associated with prednisone 0.5mg / kg oral 48h after antibiotic onset. After 15 days of treatment, there was improvement of AV, regression of vasculitis and reduction of VDRL titration to 1: 128.

Resumo A esporotricose humana e animal é uma infecção subaguda a crônica causada pelo fungo dimórfico Sporothrix schenckii. A esporotricose ocular tem ganhado destaque em função da epidemia de esporotricose urbana enfrentada pelo estado do Rio de Janeiro na última década e se apresenta classicamente como conjuntivite granulomatosa, mas formas atípicas podem ocorrer. Este artigo tem por objetivo relatar 2 casos atípicos de esporotricose ocular em pacientes imunocompetentes, ambos apresentando quadro clínico compatível com a síndrome oculoglandular de Parinaud associada à dacriocistite em um caso e presumivelmente à coroidite no outro caso.
Abstract Human and animal sporotrichosis is an infection caused by the dimorphic fungus Sporothrix schenckii, which is classified from subacute to chronic. Ocular sporotrichosis has been highlighted due to the epidemic of urban sporotrichosis faced by the state of Rio de Janeiro in the last decade and presents classically as granulomatous conjunctivitis, but atypical forms may occur. This article aims to report two atypical cases of ocular sporotrichosis in immunocompetent patients, both presenting a clinical picture compatible with Parinaud oculoglandular syndrome associated with dacryocystitis in one case and presumably to choroiditis in the other case.

Resumo A Síndrome de Blau é uma doença de caráter hereditário autossômico dominante a qual também pode ocorrer de forma esporádica via mutação "de novo". Em geral, tem aparecimento precoce ainda na primeira infância e sua tríade clássica inclui artrite, dermatite e uveíte. Este trabalho visa relatar as manifestações clínicas e principalmente oftalmológicas de uma paciente diagnosticada com Síndrome de Blau com ênfase ao achado incomum de infiltrados corneanos subepiteliais, raramente descrito na literatura.
Abstract The Blau syndrome is an autosomal dominant hereditary disease which can also occur sporadically via "de novo" mutation. Overall it has early onset and its classic triad includes arthritis, dermatitis and uveitis. This paper describes clinical and mainly especially ophthalmologic manifestations of a patient diagnosed with Blau syndrome with emphasis on an uncommon finding of corneal subepithelial infiltrates, rarely described in the literature.

Resumo Relatamos um caso atípico de uma paciente de 40 anos com apresentação completa da Síndrome de Vogt-Koyanagi-Harada (SVKH) que após 17 anos do diagnóstico inicial evoluiu com descolamento seroso de coroide. A paciente procurou atendimento com queixa de dor em olho esquerdo (OE). O exame oftalmológico revelou acuidade visual (AV) igual a de movimento de mãos, à biomicroscopia foi observada reação inflamatória granulomatosa na câmara anterior, a tonometria foi igual a 0 mmhg, e a fundoscopia indevassável pela pouca midríase e turvação de meios em OE. O descolamento seroso de coroide foi avaliado através de ultrassonografia ocular. A abordagem terapeutica intituida para paciente consistiu em prednisona 1mg/kg/dia via oral, dexametasona 1mg/mL e atropina 1% colírios. A evolução do quadro foi satisfatória, com melhora da AV para 20/40, ausência de reação inflamatória em câmara anterior, normalização da pressão intraocular e resolução do descolamento seroso de coroide em OE. Concluimos que a fase crônica da SVKH, apesar da manifestação classicamente descrita ser uveíte anterior, pode ter outras apresentações e o descolamento seroso da coroide é uma rara complicação.
Abstract We report an atypical case of a 40-year-old woman with complete presentation of Vogt-Koyanagi-Harada Syndrome (VKH) who presented with unilateral serous choroidal detachment 17 years after the diagnosis. The patient complained of pain in the left eye, the ophthalmologic examination revealed visual acuity (VA) equal to hand motion; biomicroscopy revealed a granulomatous inflammatory reaction in the anterior chamber, tonometry was equal to 0 mmhg, and the fundoscopy was impracticable. Serous choroidal detachment was assessed by ocular ultrasonography. The therapeutic approach proposed for the patient consisted of prednisone 1mg / kg / day orally, dexamethasone 1mg / mL and atropine 1% eye drops. The evolution of the condition was satisfactory, with VA improvement to 20/40, absence of inflammatory reaction in anterior chamber, normalization of intraocular pressure and resolution of serous choroidal detachment in OS. We conclude that the chronic phase of VKH, although classically described as anterior uveitis, may have other presentations and the serous choroid detachment is a rare complication.

Resumo Objetivo: Avaliar em qual fase da síndrome de Vogt-Koyanagi-Harada (SVKH) os pacientes recebem o primeiro atendimento em serviço especializado. Métodos: Foram analisados prontuários de 14 pacientes atendidos no Setor de Uveítes do Hospital Universitário Clementino Fraga Filho da UFRJ no período de janeiro de 2014 a março de 2017. Nesta análise, foram observados o sexo, a idade, a fase da doença e a acuidade visual destes pacientes com ao menos doença provável da SVKH. Resultados: Observamos que 35,4% dos pacientes apresentavam a doença ainda na fase uveítica e que 78,5% destes pacientes apresentava acuidade visual igual ou pior que 0,05. Destes pacientes, 78,5% eram do sexo feminino e 21,5% do sexo masculino e a mediana de idades foi de 34 anos. Conclusão: Os pacientes analisados obtiveram dificuldade em ter acesso precoce a um setor especializado, afetando assim, diretamente o tratamento e prognóstico visual.
Abstract Objective: To evaluate in which phase of Vogt-Koyanagi-Harada (VKH) syndrome the patients receive the first attendance in specialized service. Methods: A retrospective study was conduted to evaluate medical records of 14 patients with VKH in the Clementino Fraga Filho University Hospital of the Federal University of Rio de Janeiro from January 2014 to March 2017. In this analysis, gender, age, stage of disease and visual acuity of these patients with at least probable VKH were recorded. Results: Of these patients, 78.5% were female and 21.5% male and the median age was 34 years. We observed that 35.4% of the patients had the disease still in the uveitic phase and that 78.5% of these patients had visual acuity equal to or worse than 0.05. Conclusion: There is a delay in the admission of these patients to a specialized sector, thus affecting directly the treatment and visual prognosis.

OBJECTIVE: Bevacizumab has been widely used as a vascular endothelial growth factor antagonist in the treatment of retinal vasoproliferative disorders in adults and, more recently, in infants with retinopathy of prematurity. Recently, it has been proposed that vascular endothelial growth factor acts as a protective factor for neurons and glial cells, particularly in developing nervous tissue. The purpose of this study was to investigate the effects of bevacizumab on the developing retinas of juvenile rabbits. METHODS: Juvenile rabbits received bevacizumab intravitreously in one eye; the other eye acted as an untreated control. Slit-lamp and fundoscopic examinations were performed both prior to and seven days after treatment. At the same time, retina samples were analyzed using immunohistochemistry to detect autophagy and apoptosis as well as proliferation and glial reactivity. Morphometric analyses were performed, and the data were analyzed using the Mann-Whitney U test. RESULTS: No clinical abnormalities were observed in either treated or untreated eyes. However, immunohistochemical analyses revealed a reduction in the occurrence of programmed cell death and increases in both proliferation and reactivity in the bevacizumab-treated group compared with the untreated group. CONCLUSIONS: Bevacizumab appears to alter programmed cell death patterns and promote gliosis in the developing retinas of rabbits; therefore, it should be used with caution in developing eyes.

PURPOSE: The primary objective of this case series was to get electroretinographic data in subjects with sickle cell disease. The secondary purpose was to identify ocular changes, their frequency and stage of evolution. METHODS: 90 patients aged between 8 and 75 years were evaluated. They were subjected to complete ophthalmological examination, indirect ophthalmoscopy, retinography, angiography and electroretinography. Electroretinograms with amplitude of wave b less than 400 mW were considered subnormal. Prevalence study was conducted using the Chi-square test, P<0.001. RESULTS: The electroretinogram was subnormal in 27 (30%) of 90 patients, but of these, only 4 (4.4%) had proliferative retinopathy. The sign of comma in 95% of individuals, the retinal vascular tortuosity in 36.6% and black sunburst in 24.4% were the most frequent changes. CONCLUSION: No correlation between sickle cell disease and electroretinographics changes, as described in other studies, were noted. On the other hand, the ocular findings corroborate the previous researches.

OBJETIVO: O objetivo principal desta série de casos foi obter dados eletrorretinográficos em indivíduos portadores de síndrome falcêmica. O objetivo secundário foi identificar alterações oculares, sua frequência e o estágio de evolução. MÉTODOS: Foram avaliados 90 portadores de doença falciforme, com idade entre 8 e 75 anos, submetidos a exame oftalmológico completo, mapeamento de retina, retinografia, angiografia fluoresceínica e eletrorretinografia. Eletrorretinogramas com amplitude da onda b inferior a 400 mW foram considerados subnormais. Foi realizado estudo de prevalência, utilizando o teste do Chi-quadrado, sendo P<0,001. RESULTADOS: O eletrorretinograma se mostrou subnormal em 27 (30 por cento) dos 90 pacientes, mas destes, apenas 4 (4,4 por cento) apresentavam retinopatia proliferativa. O sinal da vírgula em 95 por cento dos indivíduos, a tortuosidade vascular retiniana em 36,6 por cento e o "black sunburst" em 24,4 por cento foram as alterações mais encontradas. CONCLUSÃO: Não foi observada correlação entre a doença falciforme e alterações eletrorretinográficas, como descrito em outros estudos. Por outro lado, os achados oculares corroboram pesquisas anteriores.

RESULTS: The electroretinogram was subnormal in 27 (30 percent) of 90 patients, but of these, only 4 (4.4 percent) had proliferative retinopathy. The sign of comma in 95 percent of individuals, the retinal vascular tortuosity in 36.6 percent and black sunburst in 24.4 percent were the most frequent changes. CONCLUSION: No correlation between sickle cell disease and electroretinographics changes, as described in other studies, were noted. On the other hand, the ocular findings corroborate the previous researches.

PURPOSE: To evaluate and to correlate the central corneal thickness with the ocular axial length in patients with primary open-angle glaucoma, primary angle-closure glaucoma and individuals with normal eyes. METHODS: The sample was composed of 94 patients' eyes, divided into three groups constituted of 33 eyes of 33 primary open-angle glaucoma patients, 30 eyes of 30 primary angle-closure glaucoma patients and 31 normal eyes of 31 individuals. The central corneal thickness and the axial length were measured by ultrasonic pachymeter and biometry by A-scan ultrasound, respectively. RESULTS: The results showed a mean of 535.1 mm central corneal thickness in primary angle-closure glaucoma group, 520.6 mm in primary open-angle glaucoma group and 519.2 mm in normal eyes (p=0.18). The ocular axial length on primary angle-closure glaucoma group was 22.16 mm and on primary open-angle glaucoma and normal eyes group was 22.68 mm and 22.64 mm, respectively (p=0.13). There was no significant correlation between corneal thickness and axial length in the primary angle-closure glaucoma group (r=-0.085; p=0.65), the open-angle glaucoma group (r=-0.070; p=0.69) and the normal eyes group (r=-0.120; p=0.52). CONCLUSIONS: The results of this assay suggest that there is no correlation between the central corneal thickness and the axial length in patients with glaucoma and individuals with normal eyes.

PURPOSE: To measure, using the retinal thickness analyzer, the mean foveal thickness and the mean perifoveal thickness values on patients suffering from mild non-proliferative diabetic retinopathy without clinically detectable macular edema (classified by the ETDRS study), and compare them with healthy individuals. METHODS: Observational analytical retrospective case-controlled study, on a sample of 79 eyes (39 affected and 40 control). The sample was selected from by exams previously taken at Centro Brasileiro de Cirurgia de Olhos (CBCO) (from 1999 to 2003) stored in the retinal thickness analyzer. The control group was selected according to specific criteria. The affected group was formed according to the research inclusive and exclusive criteria. The results were submitted to statistical tests for reliability. RESULTS: In the control group the values obtained for mean foveal thickness were around (mean=147.4 micra+/-15.4 micra standard deviation) and for mean perifoveal thickness were around (mean=193.8 micra+/-24.6 micra standard deviation). Patients with mild non-proliferative diabetic retinopathy presented foveal thickness around (mean=198.9 micra+/-48.3 micra standard deviation) and perifoveal thickness around (mean=194.2 micra+/-26.4 micra standard deviation). CONCLUSION: An increase of mean foveal thickness on diabetic patients who have not shown clinical signs of macular edema was noted, which was proved by statistical tests. Such results are similar to the values found in medical literature.

OBJETIVO: Correlacionar a espessura corneana central com o comprimento axial ocular nos portadores de glaucoma primário de ângulo aberto, com glaucoma primário de fechamento angular e indivíduos com olhos normais. MÉTODOS: A amostra foi constituída de 94 olhos de 94 pacientes, divididos em três grupos compostos por 33 olhos de 33 pacientes portadores de glaucoma primário de ângulo aberto, 30 olhos de 30 pacientes com glaucoma primário de fechamento angular e 31 olhos normais de 31 indivíduos. A espessura corneana e o comprimento axial do olho foram obtidos pela paquimetria ultrassônica e ecobiometria, respectivamente. RESULTADOS: A média da espessura corneana central foi de 535,1 mm no glaucoma primário de fechamento angular; 520,6 mm no glaucoma primário de ângulo aberto e 519,2 mm nos olhos normais (p=0,18). A média do comprimento axial do globo ocular nos portadores de glaucoma primário de fechamento angular foi de 22,16 mm e nos grupos com glaucoma primário de ângulo aberto e olhos normais foram de 22,68 mm e 22,64 mm, respectivamente (p=0,13). Não houve correlação significativa entre a espessura corneana central e comprimento axial do globo ocular nos grupos com glaucoma primário de fechamento angular (r=-0,085; p=0,65), glaucoma primário de ângulo aberto (r=-0,070; p=0,69) e olhos normais (r=-0,120; p=0,52). CONCLUSÃO: Os resultados deste trabalho sugerem não haver correlação entre a espessura corneana central e o comprimento axial do globo ocular nos portadores de glaucoma e indivíduos com olhos normais.
