Active clinical trials for "Eye Diseases"

To investigate prevalence of dry eye disease in Norwegian patients with age-related macular degeneration receiving intravitreal injections, as well as to reveal possible risk factors of DED in this population.

The purpose of this clinical trial is to evaluate the effect of light-emitting diodes (LEDs) with a continuous spectrum of 430-780 nm for lighting in the classroom on myopia prevention among children in Grades 2 and 3.

A Multi-Centre, Randomised, Controlled, Masked Phase 2 Study of the Safety and Efficacy of KIO-101 Ophthalmic Solution, versus Vehicle Control in the treatment of Dry Eye Disease in Patients with Autoimmune Disease

To establish a deep learning system of various ocular fundus disease analytics based on the results of multimodal examination images. The system can analyze multimodal ocular fundus images, make diagnoses and generate corresponding reports.

To compare the prevalence of eye disease between children and adolescents with diabetes mellitus and healthy people, and to analyze the related factors of eye diseases in diabetic patients.

The primary objective of this project is to understand the reasons why patients agree / disagree to take part in ophthalmology research. This will be done by asking participants to complete a Research Questionnaire.

This study offers evaluation and treatment for patients with corneal or retinal diseases, such as corneal opacities or diabetic retinopathy. The protocol is not designed to test new treatments; rather, patients will receive current standard of care treatments. The purpose of the study is twofold: 1) to allow ophthalmologist at Chang Gung Memorial Hospital (CGMH) to increase their knowledge of altered microenvironment in the corneal or retinal disorders and identify new pathways of possible research in this area; and 2) to establish a list of patients who may be qualified for new research as they are recruited. (Participants in this protocol will not be required to join a new study; the decision is dependent on the patients themselves.) Participants will be followed at least 3 months. Follow-up visits are scheduled according to the standard of care for the individual patient's ocular problems. Visual acuity and intraocular pressure will be checked at each visit, and some of the screening tests described above may be repeated to follow the progress of disease and evaluate the response to treatment.

The investigators are conducting a 5-year prospective, cluster-randomized controlled trial, funded by the Centers for Disease Control (CDC), which provides vision screenings to underserved, vulnerable New York City residents living in affordable housing buildings in Harlem and Washington Heights.

Characterize potential biomarkers of sight-threatening eye diseases based on the information acquired in clinical practice at CEC, AIBILI

Background: - Best Vitelliform Dystrophy (Best disease), Late-Onset Retinal Degeneration (L-ORD), and Age-Related Macular Degeneration (AMD) all affect the retina, the light sensing area at the back of the eye. Doctors cannot safely obtain retinal cells to study these diseases. However, cells collected from hair follicles, skin, and blood can be used for research. Researchers want to collect cells from people with Best disease, L-ORD, and AMD, and compare their cells with those of healthy volunteers. Objectives: - To collect hair, skin, and blood samples to study three eye diseases that affect the retina: Best disease, L-ORD, and AMD. Eligibility: Individuals affected with ocular condition is one year of age or older. Individuals affected with Best disease, L-ORD, or AMD is 18 years of age or older. Unaffected individuals are seven years of age or older. Design: The study requires one visit to the National Eye Institute. Participants will be screened with a medical and eye disease history. They will also have an eye exam. Participants will provide a hair sample, a blood sample, and a skin biopsy. The hair will be collected from the back of the head, and the skin will be collected from the inside of the upper arm.
