NCT00493064

Brief Summary

The purpose of this study is to determine whether Niacin, a B vitamin, may act as a vasodilator to encourage earlier formation of collateral blood vessels that may serve to bypass the obstructed vein in the eye. The topical steroid eye drops are aimed at reducing swelling in the retina, until the collateral vessels have a chance to develop.
