Study Summary

This project will evaluate the effect of two doses of levodopa (L-DOPA) in a randomized, placebo-controlled, double-masked clinical trial to see if vision can be improved in individuals with albinism. The hypothesis is that providing L-DOPA to the retinas of these individuals may increase melanin pigment production. Increased melanin has previously been shown to be associated with improved vision.

Primary Outcome

Binocular best-corrected visual acuity-The visual acuity test is used to determine the smallest letters you can read on a standardized chart (Snellen chart) or a card held 20 feet (6 meters) away. Special charts are used when testing at distances shorter than 20 feet (6 meters). Ranges are 20/10 vision to 20/200 vision. 20/10 being the best and 20/200 being the worse.
