Electrooculogram responses on the left from a control individual with no known retinal pathology. There is a clear dark trough around 13 minutes (arrow down) and a light peak around 25 minutes (arrow up). The Arden ratio, or the light peak to dark trough ratio, is 2.54, indicative of normal retinal pigment epithelium function (normal > 1.80, abnormal < 1.65). On the right-hand side, there is a representative image from an individual with Best macular dystrophy. Note the reduced responses for both the dark and light phase. There is a reduced Arden ratio of 1.23, suggestive of abnormal retinal pigment epithelium function. An abnormal Arden ratio is universal in Best vitelliform macular dystrophy and is the most common electroretinographic change in this disease. Other bestrophinopathies such as autosomal recessive bestrophinopathy may have normal EOG. EOG testing was completed on the Diagnosys ColorDome.

The patient is a 48 year old female who was noted to have an abnormal fundus on routine examination. Her past medical history is unremarkable. Her past family history is remarkable for her father being diagnosed with macular degeneration at age 72. Visual acuity was 20/20-1, J-2, OD and 20/20, J-1, OS. Amsler grid examinaton was normal, OU. All 6 of the AOHRR screening plates were identified correctly, OU. The 45 minute rod psychophysiologic threshold was normal, OU. ERG responses were normal for both rod and cone amplitudes. The cone implicit times were normal. The EOG was normal.
