Overview
This study was conducted to investigate the levels of ocular biomarkers from the patients with chorioretinal diseases including diabetic retinopathy, retinal vascular diseases, age-related macular degeneration (dry and wet), and retinal degeneration.
Description
This prospective, case-control study included 50 patients(50eyes) with chorioretinal diseases including diabetic retinopathy, retinal vascular diseases, age-related macular degeneration (dry and wet), and retinal degeneration. and 50 patient with nondiabetic retinopathy or cataract. Ocular fluids and blood samples were taken before injection of anti-vascular endothelial growth factor agent or pars plana vitrectomy for other retinal disease. Ocular biomarkers were analyzed.

- control patients asking cataract surgery or vitrectomy for posterior segment nonproliferative disorders.
Exclusion Criteria:
