Stargardt's disease, or fundus flavimaculatus, is an autosomally recessive inherited disorder that typically presents in the first 10 - 20 years of life. It is characterized by a decrease in visual acuity and bilateral atrophic foveal lesions. Ultimately, visual acuity will reach 20/200 to 20/400. In general, cone ERG waveforms will be reduced in amplitude, and rod amplitudes may be as well. Generally, a somewhat prolonged period of dark adaptation (45 minutes) is necessary to record maximal rod amplitudes.
