Abstract

A series of cards each containing a two dimensional array of identical Snellen 'E's' was used to determine best eccentric visual acuity in patients with macular disease having Snellen visual acuity of 20/70 or worse. Each 'full field E' card simultaneously presents the same letter to foveal and parafoveal areas. This test can therefore determine quickly if potentially useful vision is present in any area of the central visual field. In our study of 37 eyes, 70% demonstrated potential visual acuity at least 2 times better than visual acuity measured by conventional methods, and 20% demonstrated at least a 4-fold improvement. This suggests that most patients with macular disease do not spontaneously employ their best remaining area of retina for fixation.
