Abstract:Objective: To investigate the efficacy of intravitreal injection of Ranibizumab in the treatment of neovascular age-related macular degeneration (nAMD) and its effects on serum C-reactive protein (CRP), vascular endothelial growth factor (VEGF), intraocular pressure and visual acuity of patients.Methods: Seventy-four patients with nAMD in our hospital were selected as the research subjects, and they were categorized as the Ranibizumab group and the Conbercept group with random number table method, with 37 cases in each group.The two groups were treated by intravitreal injection.The visual acuity [best corrected visual acuity (BCVA)], central retinal thickness (CRT), intraocular pressure and levels of serum CRP and VEGF before treatment and 4 weeks and 12 weeks after treatment and choroidal neovascularization (CNV) leakage at 12 weeks after treatment were compared between the two groups, and the clinical efficacy was evaluated, and the occurrence of complications were recorded during treatment.Results: There was no significant difference in intraocular pressure before and after treatment between the groups and within the groups (P>0.05).Comparison of visual acuity, CRT, serum CRP and VEGF before and after treatment in the two groups all showed before treatment> at 4 weeks after treatment>at 12 weeks after treatment (P<0.05).The CRT, serum CRP and VEGF in Ranibizumab group 4 and 12 weeks after treatment were lower than those in Conbercept group (P<0.05).There was no significant difference in visual acuity between the two groups 4 and 12 weeks after treatment (P>0.05).There were no significant differences in clinical efficacy and occurrence of complications during treatment between the two groups (P>0.05).Conclusion: In the case of intravitreal injection for nAMD, the efficacy and safety of Conbercept are comparable to those of Ranibizumab, but Ranibizumab has significant advantages in improving CRT and reducing expressions of CRP and VEGF, and it has high clinical application value.
