Treatment of non-age-related macular degeneration submacular diseases with macular translocation surgery.

PURPOSE: To evaluate the use of macular translocation surgery 360 in blinding submacular diseases other than age-related macular degeneration.

METHODS

A retrospective, consecutive case review was performed of subjects treated with macular translocation surgery 360 for a submacular disease other than age-related macular degeneration. Primary outcome was change in visual acuity. Clinical data were collected and analyzed, including demographics, visual acuity, imaging features, surgery details, and complications.

RESULTS

The review identified 16 subjects who had undergone macular translocation surgery 360 from 1996 to 2009 for submacular diseases other than age-related macular degeneration. These diseases included Best disease (n = 2), angioid streaks (n = 1), pathologic myopia (n = 3), punctate inner choroidopathy (n = 2), presumed ocular histoplasmosis syndrome (n = 3), central serous chorioretinopathy (n = 1), adult-onset vitelliform macular dystrophy (n = 3), and North Carolina macular dystrophy (n = 1). Mean preop visual acuity was 20/135 (range, 20/50-20/500). A ≤ 3-line acuity loss was seen in 13 of 16 (81%) subjects. Mean postop visual acuity was 20/110 (range, 20/40-20/1,000). The most common postop complications included epiretinal membrane (50%), cystoid macular edema (31%), residual diplopia (25%), retinal detachment (13%), and recurrent choroidal neovascularization (13%). Mean follow-up was 28 months (range, 4-61 months).

CONCLUSION

Macular translocation surgery 360 may be considered in subjects with progressive bilateral vision loss from various conditions other than age-related macular degeneration. Although a significant number of complications occurred, a large percentage of subjects gained >3 lines of visual acuity (38%) and achieved a final visual acuity of ≥ 20/50 (31%).
