Intravitreal triamcinolone acetonide for cataract surgery with iris neovascularization

A 73-year-old patient with proliferative diabetic retinopathy presented with marked iris neovascularization and dense cataract that prevented retinal laser coagulation. To prevent postoperative progression of the iris neovascularization, the patient had standard cataract surgery with implantation of a foldable posterior chamber lens in combination with an intravitreal injection of 25 mg triamcinolone acetonide. During the 5.5-month follow-up, visual acuity increased from 0.10 to 0.20. With no additional retinal ablative treatment, the iris neovascularization markedly regressed within the first 5 postoperative weeks, after which a peripheral retinal laser treatment was performed, resolving the iris neovascularization. Intraocular pressure was within the normal range.
