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.

Eligibility

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

Why should I take part in a clinical trial?

Participating in a clinical trial provides early access to potentially effective treatments and directly contributes to the healthcare advancements that benefit us all.

How long does a clinical trial take place?

The duration of clinical trials varies. Some trials last weeks, some years, depending on the phase and intention of the trial.

Do I get compensated for taking part in clinical trials?

Compensation varies per trial. Some offer payment or reimbursement for time and travel, while others may not.

How safe are clinical trials?

Clinical trials follow strict ethical guidelines and protocols to safeguard participants' health. They are closely monitored and safety reviewed regularly.
