ObjectiveTo evaluate the macular visual function of patients with myopic choroidal neovascularization (MCNV) before and after intravitreal injection of conbercept.MethodsA prospective, uncontrolled and non-randomized study. From April 2017 to April 2018, 21 eyes of 21 patients diagnosed as MCNV in Shanxi Eye Hospital and treated with intravitreal injection of conbercept were included in this study. There were 9 males (9 eyes, 42.86%) and 12 females (12 eyes, 57.14%), with the mean age of 35.1±13.2 years. The mean diopter was −11.30±2.35 D and the mean axial length was 28.93±5.68 mm. All patients were treated with intravitreal injection of conbercept 0.05 ml (1+PRN). Regular follow-up was performed before and after treatment, and BCVA and MAIA micro-field examination were performed at each follow-up. BCVA, macular integrity index (MI), mean sensitivity (MS) and fixation status changes before and after treatment were comparatively analyzed. The fixation status was divided into three types: stable fixation, relatively unstable fixation, and unstable fixation. The paired-sample t-test was used to compare BCVA, MI and MS before and after treatment. The x² test was used to compare the fixation status before and after treatment.ResultsDuring the observation period, the average number of injections was 3.5. The logMAR BCVA of the eyes before treatment and at 1, 3, and 6 months after treatment were 0.87±0.32, 0.68±0.23, 0.52±0.17, and 0.61±0.57, respectively; MI were 89.38±21.34, 88.87±17.91, 70.59±30.02, and 86.76±15.09, respectively; MS were 15.32±7.19, 21.35±8.89, 23.98±11.12, 22.32±9.04 dB, respectively. Compared with before treatment, BCVA (t=15.32, 18.65, 17.38; P＜0.01) and MS (t=4.08, 3.50, 4.26; P＜0.01) were significantly increased in the eyes 1, 3, and 6 months after treatment. There was no significant difference in the MI of the eyes before treatment and at 1, 3, and 6 months after treatment (t=0.60, 2.42, 2.58; P＞0.05). Before treatment and at 1, 3, and 6 months after treatment, the proportion of stable fixation were 28.57%, 38.10%, 38.10%, 33.33%;the proportion of relatively unstable fixation were 47.62%, 47.62%, 52.38%, 57.14% and the proportion of unstable fixation were 23.81%, 14.28%, 9.52%, 9.52%, respectively. The proportion of stable fixation and relatively unstable fixation at 1, 3 and 6 months after treatment were higher than that before treatment, but the difference was not statistically significant (x²=1.82, 1.24, 1.69; P＞0.05).ConclusionBCVA and MS are significantly increased in patients with MCNV after intravitreal injection of conbercept.
