Abstract:AIM: To evaluate the efficacy and safety of intravitreal injection of conbercept in patients with neovascular age-related macular degeneration (AMD). METHODS: Retrospective review of 66 eyes of 63 patients with neovascular AMD. All patients received 0.5 mg intravitreal injections of conbercept monthly for 3 consecutive months, and then pro re nata treatment was performed. The changes of best-corrected visual acuity (BCVA) and central macular thickness (CMT) were observed before and after treatments. Minimum follow-up time was 12mo. SPSS 22.0 statistical software was used for statistical analysis. RESULTS: The mean BCVA and CMT of 66 eyes (63 patients) were 1.11±0.60, 533.20±219.95 μm at baseline, and were 0.68±0.38, 310.28±125.60 μm at 3mo. No subjects were lost during the first three months, the improvements were all significantly (P<0.05). During the whole follow-up time of 12mo, 15 subjects (18 eyes) were lost. The mean BCVA and CMT of the rest 48 eyes with the follow-up time at least 1y were 0.83±0.46 and 547.59±196.77 μm at baseline, after 3mo and 12mo of conbercept injections became 0.55±0.41, 318.24±141.29 μm and 0.55±0.51, 333.87±173.25 μm. The differences were significant (P<0.05). No serious complications were observed. CONCLUSION: Intravitreal injection of conbercept appears to significantly improve visual acuity and anatomical outcomes in patients with neovascular AMD, no serious adverse reactions and complications are observed.
