Multimodal Imaging in Retinal Vasculitis.

Background: Retinal vasculitis is an inflammatory condition that affects the retinal blood vessels.

Summary: It can manifest as an idiopathic disorder or be secondary to various infectious or non-infectious diseases, mimicking syndromes, isolated ocular disorders, or drug-induced reactions. Recognizing its distinctive features is crucial for early diagnosis and accurate treatment.

Unraveling the Complexities of Severe Acute Respiratory Syndrome Coronavirus 2: A Comprehensive Ophthalmic and Systemic Perspective.

The editorial explores the profound implications of the Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) pandemic, which emerged in December 2019 and rapidly evolved into a global health crisis. Despite initial focus on respiratory symptoms, the virus revealed significant ocular implications, prompting a reevaluation of the eye's role in its transmission, diagnosis, and systemic effects. The paradoxical nature of SARS-CoV-2-simultaneously novel and familiar within the coronavirus family-has been central to guiding the global medical response, including the swift development of vaccines.

Clinical patterns and risk factors in scleritis: a multicentric study in Colombia.

Purpose: This study aims to describe the clinical characteristics of scleritis in a large cohort of Colombian patients and identify factors associated with the clinical presentation.

Methods: Retrospective case series of patients with scleritis from 2015 to 2020. Clinical records were obtained from seven uveitis referral centers in Colombia.

Early microvascular changes in patients with prediabetes evaluated by optical coherence tomography angiography.

Background: Timely detection of early microvascular changes in patients with prediabetes could help reduce the likelihood of progression of diabetes-related retinal complications.

Aim: To determine early microvascular changes in patients with prediabetes using optical coherence tomography angiography (OCT-A).

Methods: In this single-center retrospective case-control study, macular OCT-A images of superficial capillary plexus (SCP) and deep capillary plexus (DCP) were analyzed in non-diabetic controls, and prediabetic and diabetic subjects.
