Transscleral cyclophotocoagulation and extra-panretinal photocoagulation in treatment of neovascular glaucoma

Objective To observe the clinical results of transscleral cyclophotocoagulation(TSCPC)and extra-panretinal photocoagulation(E-PRP)in patients with neovascular glaucoma.Methods Twenty-nine eyes of 29 patients with uncontrolled neovascular glaucoma by medication were treated with TSCPC and E-PRP.All patients were followed up for 12 months.Postoperative intraocular pressure(IOP),visual acuity,and complications were observed.Results The average IOP were(44.38±10.62)mmHg(1 kPa=7.5 mmHg),(34.43±9.68)mmHg,(25.31±7.27)mmHg,(22.94±9.74)mmHg,(20.90±11.07)mmHg,(18.30±12.00)mmHg,and(18.91±5.27)mmHg,respectively,at preoperation,postoperative 1 day,1 week,1 month,3 months,6 months and 1 year.No significant difference was found in average IOP between preoperation and at postoperatie 1 day,but significant difference was found between each of the other preoperative times and preoperation(all P0.01).Visual acuity decreased in 4 eyes,improved in 7 eyes and maintained in 18 eyes.Complications were ophthalmalgia in 14 cases,uveitis in 23 cases and hyphema in 2 cases.Conclusion TSCPC and E-PRP can improve the state of retinal ischemia,reduce IOP effectively and be with few complications.It is a safe,effective treatment for neovascular glaucoma.
