Diagnosis
Asteroid hyalosis. Note the following: 1. Full-thickness limbal scar with suture in the corneal stroma. 2. Corneal stromal downgrowth through the limbal scar and spreading into the angle and onto the iris surface. 3. On one side the angle has clear spaces at the site of a haptic from an intraocular lens prosthesis. 4. In the vitreous near the far peripheral retina (near the ora serrata), there are acellular, basophilic particles that are birefringent with cross-polarized light. These are asteroid hyalosis particles. 5. The retinal ganglion cell layer is severely attenuated throughout the retina, secondary to chronic glaucoma from the angle closure. 6. The retinal photoreceptors are attenuated to a variable degree throughout the retina. 7. The optic nerve has thickened pial septae and loss of the axon bundles along with cupping of the nerve head; these features indicate glaucomatous optic atrophy. KEY WORD: corneal scar, angle closure, glaucoma, asteroid hyalosis, optic atrophy, pseudophakia, retinal degeneration, photoreceptor degeneration.
