Oral Metformin for Treatment of ABCA4 Retinopathy

ABCA4 RetinopathyStargardt Disease2 more

Background: ABCA4 retinopathy is a genetic disease in which the ABCA4 protein is absent or faulty. It can cause waste material to collect in the eye and may cause cells to die. The cell death can lead to vision loss. Researchers want to see if an oral drug called metformin can help. Objective: To see if metformin is safe and possibly helps to slow the rate of ABCA4 retinopathy. Eligibility: People age 12 and older who have ABCA4 retinopathy and have problems with their vision. Design: Participants will be screened under a separate protocol. Participants will have a medical and family history. They will complete a questionnaire about their vision and daily activities. They will have a physical exam. They may have blood drawn through a needle in the arm. Participants will have an eye exam. Their pupils may be dilated with eye drops. Their retina may be photographed. Participants will have a visual field test. They will sit in front of a large dome and press a button when they see a light within the dome. Participants will have an electroretinogram. It examines the function of the retina. They will sit in the dark for 30 minutes. Then their eyes will be numbed with eye drops. They will wear contact lenses that can sense signals from the retinas. They will watch flashing lights. Participants will have optical coherence tomography. This non-invasive procedure makes pictures of the retina. Participants will have fundus autofluorescence. A bright blue light will be shone into their eye. Participants will take metformin by mouth for 24 months. Participants will have study visits every 6 months. Participation will last for at least 36 months....

Minocycline for Chronic Autoimmune Uveitis

MinocyclineUveitis1 more

Autoimmune uveitis is one kind of non-infectious, sight-threatening, relapsing and severe ocular disease. Approximately 20%-25% autoimmune uveitis patients suffer from the dilemma of blindness for the chronic and persistent inflammatory state in the eyes, which results in continuous destroy in the structure of the eyes and gradually leads to irreversible damage on visual function. However, it shows limiting efficacy of current treatment including glucocorticoids, immunosuppressant and biologics for chronic autoimmune uveitis. Minocycline has been regarded to have anti-apoptosis and immunemodulatory function for decades and it has been illustrated to be beneficial in several neuro-degenerative and neuro-inflammatory diseases. This trial aims to investigate the efficacy and safety of minocycline for chronic autoimmune uveitis with retinal degenerative changes.

Pistachios and Neural Macular Pigment

Macular DegenerationRetinal Degeneration2 more

Age-related macular degeneration (AMD) is the leading cause of irreversible vision loss as people age. Studies have shown that lutein and zeaxanthin, nutrients found in green leafy vegetables and egg yolks, can help protect against AMD in older adults. These nutrients form a pigment in the retina (macular pigment) that can help protect the retina from light damage. Pistachios are rich sources of both lutein and zeaxanthin; thus, dietary intake of pistachios could serve as a beneficial food source for eye health.

Bimodal and Coaxial High Resolution Ophtalmic Imaging

Retinitis PigmentosaMaculopathy10 more

The knowledge of the pathogenesis of retinal affections, a major cause of blindness, has greatly benefited from recent advances in retinal imaging. However, optical aberrations of the ocular media limit the resolution that can be achieved by current techniques. The use of an adaptive optics system improves the resolution of ophthalmoscopes by several orders of magnitude, allowing the visualization of many retinal microstructures: photoreceptors, vessels, bundles of nerve fibers. Recently, the development of the coupling of the two main imaging techniques, the Adaptive Optics Ophthalmoscope with Optical Coherence Tomography, enables unparalleled three-dimensional in vivo cell-scale imaging, while remaining comfortable for the patients. The purpose of this project is to evaluate the performance of this system for imaging micrometric retinal structures.
