A Longitudinal Study To Identify Early Non-invasive Ocular Markers of Diabetic Complications

This is a human subject study looking at the complications arising in newly diagnosed diabetic patients using non-invasive measures, optical coherence tomography (OCT) and corneal confocal microscope (CCM), indicative of peripheral neuropathy and diabetic retinopathy. Through the use of these devices we would like to determine the onset of corneal nerve fiber alterations and retinal thinning in newly diagnosed diabetics. This information could help investigators find early and reversible biomarkers to target for therapeutic options.

Investigating Face Processing Behavior and Neural Circuitry

The ability to recognize faces varies across people. We are studying this variability in behavior and in brain responses in young adults (ages 21-25 years) in the Lab of Developmental Neuroscience at Penn State. If eligible, you will do face recognition tasks on the computer and answer survey questions. You may also be asked to participate in another session in which we take pictures of your brain using MRI. Volunteers are paid $10/hr for time in the lab.

Inherited Retinal Degeneration: Disease Registry and Longitudinal Analysis of Clinical Endpoints

This is a human subject study looking to establish a disease registry for patients with inherited retinal dystrophy. The project will gather data using the following ophthalmological measurements: Goldmann visual fields, full field ERG, multi focal ERG, fundus photos and OCT imaging. The database is necessary for the development of a Retinal Dystrophy Center at the Penn State Eye Center.
