Free Migration of Intraocular Glass in Aphakia after Glaucoma Surgery.

PURPOSE: To describe a case of free migration of intraocular glass in aphakia after glaucoma surgery. METHODS: We report the case of a 27-year-old man with a history of perforating injury to the right eye 10 years previously and glaucoma surgery 1 year previously presenting with 1 month of pain and frequent floaters in front of the right eye. On examination, the glass fragment was seen to lie free in the anterior chamber or migrate backwards through the pupil, remaining mobile on the inferior retinal surface when the patient was prone or supine, respectively. RESULTS: The fragment was surgically removed. CONCLUSION: Late migration of glass intraocular foreign bodies is a rare clinical entity, and the exact mechanism causing the migration of intraocular glass remains controversial. Early intervention must be weighed against the hazards of removal and the necessity of close follow-up.
