“…2,3 In the 42 cases reported in the literature, 21 of 42 (50%) had a best-corrected visual acuity of 20/25 or better, 5 of 42 (12%) between 20/30 and 20/40, and 16 of 42 (38%) below 20/40. 3,5–26 The factors related to decreased visual acuity are macular edema, 11,13 amblyopia, 11 vitreomacular traction and surrounding foveal traction with an epiretinal membrane, 2,6,11 and tractional macular hole formation. 12,25 Interestingly, mild surrounding retinal traction is a common finding and may provide the pathophysiological basis for the development of foveal traction and macular holes.…”
