The authors report the histopathologic features of a human enucleated eye with an Ex-PRESS shunt (Optonol, Ltd., Neve Ilan, Israel). An 86-year-old man with a blind painful eye underwent enucleation. He had a history of glaucoma with an Ex-PRESS shunt implanted. Histopathologic evaluation of the specimen showed a thin layer of fibrotic tissue surrounding the implant. In this case, the Ex-PRESS shunt was relatively well tolerated in the human eye.
