Table 1.
Subjects are separated by diagnosis

Number of patients per condition is listed with number of eyes tested per method. Mean age, median visual acuity and mean dark-adapted rod ERG amplitude are listed with standard deviations. Affected subjects with measureable ERGs met the visual field criteria. Values assigned for acuities unmeasurable by ETDRS vision chart were as follows: CF 1.7 logMAR, LP 2.0 logMAR and NLP 3.0 logMAR
