    Abstract:
    PURPOSE: The aim of this study was to demonstrate the spatial pattern of retinal pigment epithelium (RPE) tear development and progression after antivascular endothelial growth factor therapy for neovascular age-related macular degeneration. METHODS: We retrospectively reviewed six eyes with neovascular age-related macular degeneration that showed RPE tears after administration of intravitreal antivascular endothelial growth factor agents and were followed up for 12 months. The patterns of RPE tear development and progression were evaluated by analyzing positional relationships among the locations of the choroidal neovascularization membrane and pigment epithelial detachment (PED) area at baseline and the tear area using spectral-domain optical coherence tomography, color photography, fluorescein angiography, and fundus autofluorescence images. RESULTS: Pretear OCT images revealed fibrovascular PED in all eyes, one of which showed complications of hemorrhagic PED after treatment. In five eyes, RPE tears developed at the PED edge located on the opposite side of the choroidal neovascularization membrane. In the eye showing hemorrhagic PED, the RPE tear developed along the wide area of the PED edge. The torn RPE monolayer contracted toward the side of the choroidal neovascularization membrane in all eyes, and RPE loss involved the fovea in five eyes that showed significantly worse visual acuity (VA) after 12 months in comparison with the baseline value before the tear (logMAR VA; 0.3 vs. 1.29; P < 0.02). CONCLUSION: The location of choroidal neovascularization membrane in PED determines the spatial pattern of RPE tear development and progression and helps to predict the visual outcome after RPE tears.
