Purpose: The aim of this study was to investigate the presenting sign of retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations, a rare autosomal dominant condition caused by mutations in the TREX1 gene, and to explore the potential efficacy of bevacizumab in preventing capillary occlusions.
Methods: Observational case report with the use of ultra-widefield fluorescein angiography, optical coherence tomography, and optical coherence tomography angiography.
Results: A 31-year-old man with a family history of retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations presented with a scotoma in his left eye. The visual acuity was 20/20 in both eyes, and his examination was notable for scattered cotton wool spots in the retina of both eyes as well as an area of paracentral acute middle maculopathy in the left eye. Ultra-widefield fluorescein angiography revealed peripheral capillary nonperfusion and vascular leakage corresponding to the cotton wool spots. Spectral domain optical coherence tomography and optical coherence tomography angiography confirmed the presence and distribution of superficial capillary plexus and deep capillary plexus ischemia. Neurologic examination and imaging were normal. A trial of monthly intravitreal bevacizumab injections to the left eye over 6 months resulted in diminished capillary leakage.
Conclusion: Retinal vasculopathy with cerebral leukoencephalopathy and systemic manifestations is a rare genetic condition manifested most commonly by cerebral and retinal ischemia. This retinal vasculopathy leads to occlusions of small-caliber retinal vessels in the superficial plexus and deep plexus with resulting cotton wool spots and paracentral acute middle maculopathy, respectively. Recognition of the retinal findings by ophthalmologists and neurologists may avoid unnecessary brain biopsies in diagnosing this rare disorder.

Objective: Diabetic retinopathy (DR) is a retinal microangiopathy caused by diabetes mellitus. miRNAs have been shown to be involved in DR-associated micro vessel formation, influence the DR progression, and may be a therapeutic strategy for DR. miRNA-19a-3p is highly expressed in the vitreous of DR patients, however, its mechanism in the occurrence and development of DR is unclear.

Localized oxidative stress plays a key role in the development of retinal degenerative diseases, with diabetic retinopathy (DR) being one of them, contributing significantly to this vision-threatening complication of diabetes. Increased oxidative burden leads to dysfunction across various retinal cell types, including vascular endothelial cells, neurons, glial cells and pericytes. Importantly, even after achieving normalized glycemia, the detrimental effects of oxidative stress persist.

We evaluate the administration protocols, diagnostic utility, and safety of oral fluorescein angiography (OFA) in pediatric ophthalmological diseases, with a secondary objective of comparing OFA to intravenous fluorescein angiography (IVFA) in terms of image quality and clinical utility. A comprehensive search of PubMed, Embase, and Web of Science was conducted, focusing on studies involving pediatric patients. Fifteen studies were included, with 11 assessing the utility and safety of OFA and 4 comparing it to IVFA.

Background: In recent years, artificial intelligence and machine learning algorithms have been used more extensively to diagnose diabetic retinopathy and other diseases. Still, the effectiveness of these methods has not been thoroughly investigated. This study aimed to evaluate the performance and limitations of machine learning and deep learning algorithms in detecting diabetic retinopathy.

Background: Retinal artery occlusion due to infective endocarditis is rare, and only a few cases have been reported in literature. Systematic and comprehensive studies of patients with this ophthalmological disease may help uncover serious underlying medical conditions.
Case Presentation: We present a case of an 80-year-old Brazilian woman with bilateral retinal artery occlusion as the initial presentation of Erysipelothrix rhusiopathiae endocarditis.
