Abstract:AIM: To evaluate the one-year outcome of intravitreal conbercept injections for the treatment of choroidal neovascularization secondary to pathological myopia(pm-CNV)by optical coherence tomography angiography(OCTA).
METHODS: The medical records of 26 consecutive eyes of 23 patients who received intravitreal injections of conbercept for pm-CNV with a follow-up of 1y were retrospectively reviewed. All the patients were diagnosed by fundus fluorescein angiography(FFA)and OCTA at the first visit. All approaches were performed as “1+PRN” treatment. Outcomes included best-corrected visual acuity(BCVA), central foveal thickness(CFT)and the mean CNV area by OCTA.
RESULTS: Mean BCVA improved from(0.66±0.51)at baseline to(0.39±0.38)at 1y(t=3.528, P=0.004). The CFT before treatment and after 1y after were(275.08±48.74)μm and(205.15±43.74)μm respectively(t=4.630, P=0.001). The mean pm-CNV areas before treatment and after 1y treatment were(0.48±0.24)mm2 and(0.15±0.11)mm2 respectively, with a significant difference among them(t=5.329, P=0.000). Twenty-one eyes had no needs after the first treatment. Four eyes received 2 injections and only one eye received 3 injections. No severe adverse events were noted relevant to the therapy.
CONCLUSION: Intravitreal conbercept can improve the vision and relieve CFT and CNV area for the treatment of pm-CNV with “1+PRN” by OCTA for 1y, however, long-term follow-up still need to be performed.
