About

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.

Full 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.

Enrollment: 100 estimated patients

Sex: All

Ages: 20 to 80 years old

Volunteers: Accepts Healthy Volunteers

Inclusion criteria

• age over 20 years
• patients requiring ophthalmologic treatments for different degrees of decreasing of visual acuity.
• patients with chorioretinal diseases including diabetic retinopathy, retinal vascular diseases, age-related macular degeneration (dry and wet), and retinal degeneration.
• control patients asking cataract surgery or vitrectomy for posterior segment nonproliferative disorders.

Exclusion criteria

• under the age of 20 years
• patients that received any anti-vascular endothelial growth factor agent for proliferative disease before taking sample of aqueous humor
• patients that did not signed the informed consent of the trial
• patients with intraocular inflammations or infections that requiring any pharmaceutical agent
• patients with recent ocular trauma
