ABSTRACT Objective: To analyze the perception and knowledge that diabetic patients treated in the Outpatient Endocrinology Department have about diabetic retinopathy. Methods: This study was conducted during the first semester of 2024 and involved diabetic patients from the Endocrinology Department of the HSCMV. All patients over 18 years of age with a diagnosis of diabetes mellitus who signed the Informed Consent Form were included. The variables analyzed, collected through a questionnaire and supplemented with data from the electronic medical records, […]

ABSTRACT Diabetic retinopathy is the leading cause of vision loss among working-age adults in the Western world. Although it has traditionally been considered a microvascular disease, growing evidence suggests that neurodegenerative changes may occur even before the appearance of microvascular damage. The aim of this review was to provide a comprehensive summary of the current evidence regarding neurodegenerative changes in diabetic retinopathy. This is a narrative review, in which we performed a comprehensive literature search from August 15, 1998, to […]

ABSTRACT Objective: To outline the clinical and epidemiological profile of patients attended at the ophthalmology outpatient clinic of a university hospital, with emphasis on the presence of diabetes mellitus, diabetic retinopathy, and the type of ophthalmological follow-up. Methods: This was a cross-sectional, observational, and retrospective study in which electronic medical records of patients attended at the Ophthalmology Outpatient Clinic were analyzed during the period from March to August 2023 and compared with the same period in 2024. Medical records with […]

ABSTRACT An 81-year-old male patient with systemic hypertension, diabetes mellitus, and dyslipidemia presented with sudden visual acuity loss in the right eye (RE) due to a branch retinal artery occlusion (BRAO) associated with macular edema. Despite treatment with intravitreal bevacizumab, the patient developed persistent inner retinal ischemia, evidenced by optical coherence tomography (OCT) findings of retinal inner plexiform layer (RIPL) alterations. Years later, he suffered an ischemic stroke, highlighting the association between retinal ischemic changes and systemic vascular risk. This […]

ABSTRACT Diabetic retinopathy and diabetic macular edema are leading causes of preventable vision loss, with a rising global impact due to the increasing prevalence of diabetes mellitus. This review article synthesizes current evidence regarding the management of diabetic retinopathy, addressing pathophysiological mechanisms and evidence-based therapeutic recommendations from major clinical trials. Key topics include screening strategies, updated classification systems, systemic control, and ocular therapies such as anti-vascular endothelial growth factor (anti-VEGF) agents, corticosteroids, laser photocoagulation, and vitrectomy. Emerging medication approaches, sustained-release […]

ABSTRACT Objective To gather the available evidence in the literature on the prevalence and associated factors of diabetic retinopathy (DR) in Latin America. Methods This scoping review was developed according to the PRISMA-ScR. Prevalence data were summarized by weighted mean, considering the type of DM and country. For the analysis of associated factors, meta-analyses were performed with the most homogeneous studies, and the ORs and their 95%CIs were calculated. Results Forty-two articles published between 2004 and 2020 were included in […]

ABSTRACT Currently the “pandemic” of diabetes mellitus is noted. The incidence and prevalence of diabetes and diabetic retinopathy, the most common microvascular complications of diabetes, are exponentially growing due to increased life expectancy in many parts of the world. The increasing number of people suffering from diabetic retinopathy not only highlights medical issues, but also an economic burden, representing a medical and social challenge. It is extremely important to identify a disease as soon as possible and successfully treat it. […]

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 […]
