The Role of OCTA in Evaluating Diabetic Retinopathy Progression: A Meta-Analysis.

Background: Diabetic retinopathy (DR) substantially threatens ocular health, necessitating the accurate and prompt assessment of its onset and progression. Optical coherence tomography angiography (OCTA) is a valuable tool for evaluating periocular microvascular indicators, offering insights crucial for diagnosing and treating DR.

Objective: This meta-analysis aims to evaluate the progression of diabetic retinopathy (DR) by examining periocular microvascular indicators using optical coherence tomography angiography (OCTA).
