ABSTRACT Purpose To evaluate the retinal blood vascular network of the retinographies of patients with different grades of diabetic retinopathy. Methods Ninety Retinographies (MESSIDOR database) were used, with different grades of diabetic retinopathy divided into 4 groups: no retinopathy (n=23), grade one (n=20), grade two (n=20) and grade three (n=27) diabetic retinopathy. The grades of diabetic retinopathy were classified according to the number of microaneurysms, number of hemorrhages and the presence of neovascularization. The images were skeletonized and quantified by […]

ABSTRACT Objective To evaluate the impact of diabetic retinopathy (DR) screening using color retinography in diabetic patients. Methods Retrospective descriptive study, evaluating reports of all retinographs performed since the implementation of the protocol for screening for diabetic retinopathy in diabetic patients followed up at the endocrinology outpatient clinic of a tertiary hospital of the Unified Health System, from May 2018 to May 2020. Results 727 diabetic with age range from 14 to 91 years old, the majority being 60 years […]

ABSTRACT The objective of this article was to review the disorganization of inner retinal layers as a biomarker in diabetic macular edema. A systematic search was conducted in PubMed®/MEDLINE®, Cochrane and Embase until August 2021. The keywords used were: “disorganization of inner retinal layers (DRIL)”, “diabetic macular edema (DME)” and “biomarkers”. No restrictions were imposed on the types of study to be included. The studies selected for eligibility were those that included the diagnosis of diabetic macular edema (center involved, […]

ABSTRACT Objective: To assess effectiveness of fundus photography and fluorescein angiography in diagnosis and screening of diabetic retinopathy. Methods: A retrospective study of 398 diabetic patients, based on analysis of results of both tests. Results: Results of fluorescein angiography and fundus photography coincided in 77.4% of cases, and there was no significant difference in staging and identification of retinopathy by both methods. Conclusion: There was no significant difference between both methods regarding the capacity to diagnose the disease, showing no […]

ABSTRACT Objective: To estimate the prevalence of diabetic retinopathy in patients with diabetes, from a Brazilian capital city, and to correlate with the risk factors present in the studied population. Methods: A cross-sectional observational study, based on the report of care provided by a campaign, in 2018. The report was filled out by ophthalmologists during the joint effort, with information on patient’s gender, age, classification of diabetes mellitus, duration of illness, use of insulin, body mass index, lifestyle (smoking and […]

Abstract Objective: To evaluate the choroidal thickness (CT) in healthy Brazilian subjects using spectral-domain optical coherence tomography (SD-OCT) and to compare with choroidal thickness measured in Brazilian patients with diabetic macular edema (DME), neovascular age-related macular degeneration (AMD) and high myopia. Methods: A retrospective analysis of spectral domain optical coherence tomography (SD-OCT) images of 181 Brazilian subjects. A total of 74 eyes were included in the normal control group, 50 eyes in the nvAMD group, 44 eyes in the DME […]

Purpose: Determine the effectiveness of the use a portable handheld fundus camera as a screening method for diabetic retinopathy, compared to regular digital retinography. Methods: This is a cross-sectional, observer-masked study, evaluating 100 eyes of 51 diabetic patients undergoing a routine dilated retinography for diabetic retinopathy. Fundus images pre and post-dilation we captured by Pictor Plus (Volk Optical Inc., Mentor, USA), followed by routine digital retinography by IMAGEnet (Topcon Medical Systems, New Jersey, USA). All exams were performed by a […]

Objetivos: Comparar o efeito do ranibizumabe intravítreo (0,3mg) e triacmicinolona (4mg) em diferentes parâmetros do domínio espectral da OCT e sua relação com a acuidade visual de pacientes com edema macular diabético. Métodos: Este estudo foi concebido como um estudo prospectivo randomizado. Os pacientes foram divididos aleatoriamente em 2 grupos que receberam Ranibizumab Pro rata intravitreal (0,3mg) ou acetonido de Triamicinolona (4mg), a quem foi realizada a Spectral Domain OCT, bem como a melhor acuidade visual de Log MAR corrigida.
