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.
