Purpose: To compare the optical coherence tomographic assessment of retinal thickness and the fluorescein angiographic appearance after macular translocation surgery for subfoveal choroidal neovascularization.
Design: Retrospective, noncomparative, interventional case series.
Participants: Twenty-three consecutive eyes.
Intervention and testing: Optical coherence tomography and fluorescein angiography were performed before and 6 to 15 months (mean +/- standard error [SE], 10.4+/-0.7) after macular translocation surgery with a 360 degrees retinotomy in 23 patients, ages 48 to 79 years, with age-related macular degeneration (12 eyes), polypoidal choroidal vasculopathy (2 eyes), and high myopia (9 eyes). The diameter of the choroidal neovascularizations ranged from 0.3 to 2.6 disc diameters (mean +/- SE, 1.2+/-0.2), and the angle of rotation of the retina ranged from 11 degrees to 45 degrees (mean +/- SE, 29.1+/-2.1 degrees ).
Results: The preoperative best-corrected visual acuity ranged from hand motions to 20/100, and the postoperative best-corrected visual acuity ranged from 20/667 to 20/25. Optical coherence tomography demonstrated a concave foveal configuration after surgery in all 23 eyes, with a mean foveal thickness of 150+/-11 micro m (mean +/- SE). Fluorescein angiography showed various degrees of fluorescein leakage with a pattern similar to cystoid macular edema in 16 of 23 eyes (70%).
Conclusions: The newly located macula after macular translocation surgery with a 360 degrees retinotomy had cystoid macular edema on fluorescein angiography and normal macular configuration with normal thickness in optical coherence tomography.
