About this study
Environmental and genetic factors may play a role in the progression of ocular diseases (cataract, retinopathy, age-related macular degeneration, glaucoma, retinal detachment, ocular tumor, etc.). The goal of this project is to establish a series of case-control studies to evaluate risk factors of ocular diseases in China.
Read the detailed description
This study is designed to investigate the epidemiologic, genetic, laboratory and clinical characterization of individuals with ocular diseases (cataract, retinopathy, age-related macular degeneration, glaucoma, retinal detachment, ocular tumor, etc.). We will accrue approximately 800 patients as experimental group. The control group consists of age/sex frequency-matched subjects who will be confirmed without ocular diseases. We will explore the environmental (including family history, life style, diet, physical activity, neuropsychological functioning，plasma levels of oxidative stress and angiogenic factors, etc.) and genetic (including oxidative stress and angiogenic factors, etc.) risk factors. We will study the association between various environmental risk factors with the clinical characterization and correlation between the genetic polymorphisms and the presence of various ocular diseases.

An observational study of Ocular Diseases, run by Nanjing Medical University at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 3 inclusion and 0 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: status not confirmed, as of the sponsor's last update on 23 May 2008. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
Results are not available in the source record.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 May 2008.
