Optical coherence tomography angiography in myopic choroidal neovascularization after intravitreal ranibizumab

To describe the optical coherence tomography angiography characteristics of myopic patients with choroidal neovascularization secondary to pathologic myopia during ranibizumab therapy. Nineteen patients were enrolled in this prospective study (13 females, 6 males, mean age 55.25？±？9.63？years) for a total of 20 eyes examined (14 right eyes, 6 left eyes). Images were analyzed independently by two examiners. Mean follow-up was 5.75？±？1.88？months, with a mean intravitreal injections of 1.90？±？0.44. Mean best-corrected visual acuity at baseline was 0.39？±？0.18 logMAR versus 0.26？±？0.16 logMAR 6？months after treatment. The neovascular area (Z？=？–2.091, p？=？0.037) was significantly reduced after treatment, whereas vessel density was not (Z？=？–1.848, p？=？0.065). Moreover, the best-corrected visual acuity was increased (Z？=？–3.055, p？=？0.002). Neovascular area was significantly correlated with best-corrected visual acuity, at both baseline and follow-up (p？<？0.05). Our data suggest that optical coherence tomography angiography is a reproducible non-invasive examination with which to monitor changes in the neovascular area in patients with pathologic myopia treated with ranibizumab
