Summary
This study tests whether high-dose nicotinamide (vitamin B3) can protect vision in people with Leber's hereditary optic neuropathy (LHON), a rare genetic disease that causes sudden vision loss. Researchers will give 13 participants 2 grams of nicotinamide daily for 12 months and measure changes in eyesight. The goal is to see if this simple supplement can support eye cell health and slow or improve vision loss.
