Comparison of Visual Acuity Loss in Patients with Different Stages of Stargardt's Disease

Patients with stage 1 Stargardt's disease exhibiting fundus flecks limited to the posterior pole are more likely to maintain a level of VA at 20/200 or better when compared with patients with stage 2/stage 2-3 disease who have diffuse fundus flecks. Nevertheless, over 80% of the patients with stage 2/stage 2-3 Stargardt's disease still maintained VA of 20/200 or better. Only 5.9% of patients with stage 2/stage 2-3 had VA levels worse than 20/400. In our cohort of patients with Stargardt's disease and diffuse fundus flecks, the majority of patients did not lose VA to a greater extent than those with localized flecks.
