[Retinal hemorrhages after Ahmed glaucoma valve implantation].

A 31-year-old male patient developed uncontrolled elevation of intraocular pressure (IOP) under maximum tolerated therapy after severe blunt trauma to the right eye. For IOP control an Ahmed glaucoma valve implantation was necessary. On the first postoperative day the patient presented with retinal hemorrhages typical for decompression retinopathy. After a period of 6 months the hemorrhages had almost resolved and visual acuity was unaffected. The clinical picture of the case and possible mechanisms of this rare entity, which usually appears after incisional glaucoma surgery, are presented.
