High Resolution Retinal Imaging

Studying the morphology and function of the normal and diseased retina in vivo is needed for advancing the detection, diagnosis, and treatment of retinal disease. This protocol uses an adaptive optics scanning laser ophthalmoscope (AOSLO) to image the normal and diseased retina with individual cellular resolution non-invasively. The primary objective ...

Phase N/A

Natural History Study of Patients With X-linked Retinal Dystrophy Associated With Mutations in Retinitis Pigmentosa GTPase Regulator (RPGR)

X-linked Retinitis Pigmentosa (XLRP) is a severe form of RP with early onset of nyctalopia and progression to legal blindness by the 3rd to 4th decade. Most affected males show symptomatic night blindness before the age of 10 years, are often myopic and show fundus abnormalities and ERG changes in ...

Phase N/A

Phenotype Correlates Genotype of Inherited Retina Dystrophies Retinitis Pigmentosa Con>Rod Dystrophies.

Patients with retina dystrophies (retinitis pigmentosa, cone>rods dystrophies, Usher and syndromic, etc.) will be correlated with genotype and validate inheritance mode by segregation analysis. Ocular exam of proband, parents and two unaffected siblings is needed, retina analysis, autofluorescence and ocular coherence tomography (OCT) are needed as well as family map. ...

Phase N/A

Genetics of Charcot Marie Tooth (CMT) - Modifiers of CMT1A New Causes of CMT2

This project is to understand modifier genes and how they influence the severity of disease expression, along with identifying new forms of CMT which have not been genetically determined. Subjects who are eligible will either have CMT type 1A (CMT1A) or an unknown form of CMT. Blood will be drawn ...

Phase N/A

Evaluation of Objective Perimetry Using Chromatic Multifocal Pupillometer

Pupil light reflex (PLR) will be measured by a chromatic multifocal pupillometer in response to short and long wavelength light with small spot stimulus in 76 points of the 30 degree visual field. A computerized infrared video pupillometer will be used to record changes in pupil diameter in response to ...

Phase N/A

Inherited Retinal Degenerative Disease Registry

My Retina Tracker provides three different portals for data entry and review. An entry in My Retina Tracker is initiated by a participant, not a clinician. Using the Participant Portal, the participant establishes a username and password, is guided through on-line informed consent, and can then use an interactive guide ...

Phase N/A

Experimental and Clinical Studies of Retinal Stimulation

The study will test new ways to make the retinal prosthesis visual perception easier with auditory-visual training and how to make the retinal prosthesis work better at perceiving shapes.

Phase N/A

Treatment of RP and LCA by Primary RPE Transplantation

Early Phase I Study of the Safety and Preliminary Efficacy of Human primary Retinal Pigment Epithelial (HuRPE) Cells Subretinal Transplantation in Retinitis Pigmentosa (RP) and Leber Congenital Amaurosis (LCA) Patients

Phase N/A

The Effects of Cannabis on Visual Functions in Healthy and Retinitis Pigmentosa Patients

Twenty five healthy subjects and 25 retinitis pigmentosa patients will be recruited and will sign an informed consent form. An initial eye exam will include visual acuity and stereo vision, eye movements and eye movement recording, a full slit lamp eye exam, intra-ocular pressure measurement, visual field, OCT and electrophysiology. ...

Phase N/A

New Enrollment Post-Approval Study of the Argus II Retinal Prosthesis System

Safety data will be monitored to ensure continued acceptability of risks to study subjects. The utility (i.e. visual function and functional vision) and reliability of Argus II System will also be evaluated. There is no study hypothesis.
