Electron Microscopic Evidence of Photoreceptor Outer-segments in the Trabecular Meshwork in a Case of Schwartz-Matsuo Syndrome.

Purpose: To describe a case of photoreceptor outer segment glaucoma (Schwartz-Matsuo syndrome) with electron microscopic evidence of photoreceptor outer segments in the trabecular meshwork (TM).

Design: This is a clinicopathologic case report.

Participant: A 48-year-old Filipino man.

Methods: Specimens of aqueous humor and TM in a clinical case of Schwartz-Matsuo syndrome were examined by electron microscopy.

Main Outcome Measures: Electron photomicroscopy.

Results: Electron microscopy showed evidence of retinal photoreceptor outer-segments in both an aqueous humor and a TM specimen.

Conclusion: Schwartz-Matsuo syndrome is associated with the presence of photoreceptor outer segments in the TM.
