Abstract:
Objective To observe the efficacy and safety of intravitreal injection of conbercept for wet age-related macular degeneration.Methods Retrospective clinical study.Sixty eyes of 60 cases diagnosed as wet age-related macular degeneration (AMD) definitely were intravitreally injected conbercept 0.5 mg from March 2014 to March 2016.Follow-up time was 6 months to 12 months,averaged (8.5 ± 2.4) months.Visual acuity (ETDRS charts letter),central macular thickness (CMT),leakage of choroidal neovasculaxization (CNV) and area of CNV and complications before and after the treatment were analyzed.Results Conbercept injection therapeutic times were 1-5,the average therapeutic times were 2.80 ± 0.89.At 1 month,2 months,3 months and 6 months after treatment and the last follow up,the mean letter of ETDRS charts increased (14.76 ± 5.89) letters,(19.88 ± 7.13) letters,(24.75 ± 6.74) letters,(23.94 ±6.15) letters,(22.89 ± 8.53) letters compared with pre-operation,respectively (all P ＜0.05).CMT decreased (70.19 ± 60.56) μm,(82.07 ± 57.97) μm,(95.40 ± 87.92) μm,(97.57 ± 46.68) μm,(107.46 ± 56.82) μm compared with pre-operation,respectively (all P ＜ 0.05).Before treatment,the area of CNV leakage was (12.32 ± 5.67) mm2,and at postoperative 3 months,6months the area were statistically significant different (all P ＜ 0.05).Four cases had subconjunctival flake bleeding,intraocular pressure increased slightly in 3 cases and they all recovered at 1 week after treatment.There was no serious ocular and system complication.Conclusion Intravitreal injection of conbercept for wet AMD can improve the visual acuity,decrease CMT and inhibit the CNV regression without serious complication.
