Abstract:AIM: To observe the clinical effect of ranibizumab injection combined with vitrectomy,panretinal photocoagulation(PRP)and trabeculectomy in the treatment of neovascular glaucoma(NVG).
METHODS: Retrospective study. From March 2017 to October 2018, 44 NVG patients(44 eyes)were treated, 22 patients(22 eyes)were treated with intravitreal injection of ranibizumab + vitrectomy + PRP+trabeculectomy(group A), and 22 patients(22 eyes)were treated with intravitreal injection of ranibizumab + trabeculectomy+PRP(group B).The patients were followed up for 6mo, the visual acuity, intraocular pressure(IOP), IOP control rate, neovascularization and complications were observed.
RESULTS: There was no significant difference in IOP between the two groups before treatment(46.2±9.41mmHg vs 49.1±10.15mmHg, P>0.05). The IOP of group A was lower than that of group B at 1wk, 1mo and 6mo after treatment(P<0.05). 6mo after treatment, the visual acuity, IOP control rate(95%)and neovascularization regression(91%)in group A were better than those in group B(P<0.05), but there was no difference in the incidence of complications between the two groups during the follow-up period(P>0.05).
CONCLUSION: It is safe and effective to treat NVG with intravitreal ranibizumab injection combined with vitrectomy, PRP and trabeculectomy, which can control IOP steadily and improve visual acuity of some patients.
