Abstract
To compare the efficacy and security of conbercept and ranibizumab combined with trabeculectomy and panretinal photocoagulation for neovascular glaucoma (NVG). One hundred and sixty patients with NVG were randomly divided into a conbercept group comprised of 80 patients and a ranibizumab group comprised of 80 patients. The postoperative and preoperative visual acuities, intraocular pressures frequency of anti-glaucoma medications, and surgical complications were recorded. The expressions of vascular endothelial growth factor (VEGF), vascular endothelial growth factor receptor (FLT-1), and placenta-like growth factor (PLGF) in the aqueous humor were determined using an enzyme-linked immunosorbent assay. Examining the fundus and obtaining photographs used indirect ophthalmoscopy. Kaplan-Meier and log-rank analyses estimated the success rates. All patient follow-up periods were at 1year. The differences observed in IOP and the frequencies of anti-glaucoma medications at various follow-up time points were not statistically significant (all P > 0.05). The differences observed in both the group visual acuities at various follow-up time points were not statistically significant (P > 0.05). Rates of surgery complications were 18.75% and 25.00% in the conbercept group and ranibizumab group, respectively. The expressions of VEGF, FLT-1, and PLGF significantly decreased (all P < 0.05). The recurrence percentages were 30.00% and 36.25% after conbercept and ranibizumab treatment, respectively. The conbercept effects were similar with that of ranibizumab. Intravitreal injection of conbercept was effective for NVG treatment, which provides a new therapeutic drug for NVG treatment.
