Surgery for idiopathic macular holes associated with extensive subretinal fluid.

Purpose: To study the baseline characteristics and outcomes of surgery for idiopathic macular holes associated with localized macular detachment. Methods: In this case-control study, eight consecutive patients with idiopathic macular hole associated with localized macular detachment (cases) and 30 randomly selected patients with idiopathic macular hole not associated with macular detachment underwent macular hole surgery. Results: The mean age (62.1 versus 68.2 years; P = 0.086), mean refractive error (-0.13 versus +0.23 diopters; P = 0.68), average duration of symptoms (5.9 versus 4.6 months; P = 0.47), and macular hole stage (P = 0.43) were similar in the cases and controls. The baseline visual acuity ranged from 20/50-20/80 (1 [13%] versus 1 [3%]) to 20/100 -20/200 (2 [25%] versus 24 [80.0%]) to <20/200 (5 [63%] versus 5 [17%]) (P = 0.10). Single-operation anatomic success was achieved in 2 (25%) cases and 24 (80%) controls (P = 0.007). Visual acuity 3 months after the last macular hole surgery was worse in cases compared to controls: 20/40 in 0 Versus 6 (20%), 20/50-20/80 in 1 13%) versus 13 (43%), 20/100-20/200 in 4 (50%) versus 10 (33%), and <20/200 in 3 (38%) Versus 1 (3%) (P = 0.003). The mean improvement in visual acuity was 0.2 logMAR units in cases versus 0.4 logMAR units in controls (P = 0.054). Conclusions: Surgical outcomes for idiopathic macular hole associated with a localized macular detachment compare poorly with the outcomes for macular hole not associated with extensive surrounding subretinal fluid.
