Abstract
To report the anatomical and functional outcomes of intravitreal bevacizumab in both young and old Chinese patients with myopic choroidal neovascularization. Consecutive series of 56 eyes (52 patients) with myopic choroidal neovascularization treated exclusively with intravitreal bevacizumab were reviewed retrospectively. Data from clinical examination, fundus photography, fluorescein angiography, and optical coherence tomography were collected. Vision significantly improved after intravitreal bevacizumab in this patient series (P < 0.0001), with an average of 2.2 injections. Higher myopia was positively correlated to a worse outcome (r = -0.3, P = 0.036). Stratifying by age, the correlation between spherical equivalent and final outcome showed statistical significance (r = -0.44, P = 0.027) only in younger patients. In younger patients, both spherical equivalent (P = 0.036) and initial visual acuity (P = 0.004) were predictive factors for visual outcome after adjusting for age, spherical equivalent, and number of injections, whereas in older patients, only initial visual acuity (P < 0.0001) was predictive of visual outcome after similar adjustments. Younger patients do not have a better outcome when compared with older patients. Initial visual acuity, regardless of age, plays a more significant role. Both initial visual acuity and spherical equivalent are predictive factors for final visual acuity in young Chinese patients.
