    Abstract:
    PURPOSE: The purpose of this study was to investigate the predictors of retinal pigment epithelium (RPE) tear development after treatment for neovascular age-related macular degeneration using swept source optical coherence tomography angiography. METHODS: This prospective study included 152 treatment-naïve eyes with neovascular age-related macular degeneration without high myopia that were followed up for 1 year after treatment. Eligible eyes were classified into eyes with or without RPE tear development. They were matched in a 1:2 ratio. The areas of choroidal neovascularization (CNV) and RPE detachment (pigment epithelial detachment [PED]) were measured from optical coherence tomography angiography and OCT en face images, respectively. The optical coherence tomography angiography-specific parameters representing CNV status were analyzed. RESULTS: Eight (5.3%) of the 152 eyes developed RPE tears (RPE tear group). After matching, 16 eyes without RPE tears were analyzed (non-RPE tear group). The ratio of the CNV/PED area was lower in the RPE tear group than that in the non-RPE tear group (P = 0.007). The PED area was broader (P = 0.008), and PED height was greater in the RPE tear group (P = 0.04). Optical coherence tomography angiography-specific parameters did not differ between the two groups. CONCLUSION: Neovascular age-related macular degeneration with pretreatment broad PED, high PED, and small CNV area relative to the PED area has a high risk of RPE tear development after therapy. However, CNV status may not have an association.
