Purpose: Using anterior segment fluorescein angiography(AFA), we evaluated the relationship between the effect of vitrectomy combined with endophotocoagulation for neovascular glaucoma and the postoperative angiographic changes.
Subjects and methods: Seven eyes of 7 patients (six eyes of 6 patients had proliferative diabetic retinopathy and 1 eye of 1 patient had central retinal vein occlusion) with neovascular glaucoma underwent both vitrectomy combined with endophotocoagulation and AFA before and after surgery.
Results: Of the 7 cases, the three eyes(42.9%), ther received one vitreous surgery alone had a reduction in intraocular pressure (IOP). The other 4 with uncontrollable IOP underwent trabeculectomy additionally, and three of them achieved good control of IOP. AFA showed less dye leakage in the iris after surgery in all cases. Three of 4 eyes with less dye leakage in the chamber angle showed good IOP control. Two of 3 eyes without the change in dye leakage were treated additionally by trabeculectomy.
Conclusion: AFA is a sensitive technique in the assessment of neovascularization in the anterior segment, so that it is useful in evaluating the effect of vitrectomy combined with endophotocoagulation for neovascular glaucoma.
