Official title

A Pilot Study for the Evaluation of Minocycline as a Microglia Inhibitor in the Treatment of Central Retinal Vein Occlusions

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

Background: \- Central retinal vein occlusion (CRVO) is a blockage of the main vein that carries blood away from the retina in the back of the eye. It can lead to macular edema, a swelling of the retina that is a common source of vision loss. Studies suggest that inflammation might be a cause. Minocycline is a drug that might help prevent cells involved in inflammation from becoming activated. It is approved for use as an antibiotic, but it has not yet been tested to see if it can treat CRVO. Objectives: \- To test the safety and effectiveness of minocycline as a treatment for central retinal vein occlusion. Eligibility: \- Individuals at least 18 years of age who have central retinal vein occlusion in at least one eye, with vision between 20/32 and 20/200. Design: * This study lasts 2 years, with at least 25 visits. * Participants will be screened with a physical exam and medical history. They will also have blood tests and an eye exam. One eye will be selected as the study eye to receive the medicine. * Participants will take minocycline or a placebo pill twice a day, about 12 hours apart, for 2 years. * Participants will have monthly visits for blood tests and full eye exams to study the effect of the treatment. Other exams may include thyroid tests and eye imaging studies. Those in the study may also receive injections of a drug to prevent the growth of new blood vessels in the eye.
