Neovascular Glaucoma and Diabetic Macular Edema in a Patient with Monolateral Pseudoexfoliative Glaucoma and Type 2 Diabetes: Therapeutic Effects of Two-Sided Intravitreal Triamcinolone Acetonide Treatment

Abstract

Background: To report on the safety and efficacy of intravitreal injections of triamcinolone acetonide in a patient with diabetic macular edema in the right eye and pseudoexfoliative glaucoma complicated by iris neovessels in the left eye.Case presentation: Two intravitreal injections of triamcinolone acetonide were given (one per eye) in a 75 year-old caucasian male with macular edema in the right eye and neovascular glaucoma in the left eye. Changes in visual acuity, intraocular pressure, ophthalmoscopic examination of the anterior and posterior segment and flicker ERG response were regularly detected during a period of 6 months. Conclusion:Bilateral visual acuity improvement was obtained after each injection and maintained for the whole observation period. Central retinal thickness in the right eye decreased after intravitreal injections of triamcinolone acetonide and remained stable until the last observation 6 months later. Iris neovessels in the left eye disappeared after the injection in the left eye. Flicker ERG implicit time in the right eye improved after intravitreal injections of triamcinolone acetonide, and remained stable in the left eye. No side effects of the treatment were observed. Intraocular pressure in the right eye remained within normal values without any intraocular pression-lowering drug, whereas it showed even some decrease in the left eye, despite the presence of glaucoma.
