The purpose of the study was to investigate the clinical course of patients with idiopathic vitreomacular adhesion (VMA).
A noncomparative case series of patients who had clinical symptoms and spectral-domain optical coherence tomography findings consistent with VMA. The VMA was graded based on the optical coherence tomography findings at initial and follow-up examinations. Grade 1 was incomplete cortical vitreous separation with attachment at the fovea, Grade 2 was the Grade 1 findings and any intraretinal cysts or clefts, and Grade 3 was the Grade 2 findings and the presence of subretinal fluid.
One hundred and six eyes of 81 patients were identified as having VMA by spectral-domain optical coherence tomography at 3 retina clinics. The mean age was 73 years and the mean time of follow-up was 23 months. Forty-three eyes (41%) had Grade 1 VMA, 56 eyes (52%) had Grade 2 VMA, and 7 eyes (7%) had Grade 3 VMA. By the last follow-up, spontaneous release of VMA occurred in 34 eyes (32%), and pars plana vitrectomy was performed in 5 eyes (4.7%). Mean best-corrected visual acuity was 0.269 logarithm of the minimum angle of resolution or 20/37 at baseline (range, 20/20–20/200) and logarithm of the minimum angle of resolution 0.251 or 20/35 at the last examination (range, 20/20–20/400).
In this selected patient cohort with mild symptoms, the clinical course of patients with VMA managed by initial observation was generally favorable.
