In Brief Purpose: To examine predictive factors for visual acuity in highly myopic eyes. Methods: Consecutive patients with high myopia (≥6 diopters [D]) no other pathology such as lacquer cracks the fovea, choroidal neovascularization, or macular schisis, were evaluated. The study was performed 2 retina centers, one United States and Japan. Enhanced depth imaging optical coherence tomography obtained, central foveal, outer retinal hyporeflective layer inner segment to pigment epithelium aggregate, subfoveal thicknesses measured. Correlations calculated among measured variables acuity. Generalized estimating equation models used identify predictors of Results: New York cohort composed 35 eyes 25 who had a mean age 57 years (standard deviation, ±18.1 years) refractive error −10.9 D (±3.6 D).
