Photoreceptor outer segments in aqueous humor: key to understanding a new syndrome

Retinal detachment with oral dialyses and tears of the nonpigmented epithelium of the ciliary body sometimes accompanies aqueous cells and high intraocular pressure with its marked fluctuation. The aqueous cells consist predominantly of photoreceptor outer segments which obstruct aqueous outflow at the trabecular meshwork and induce high intraocular pressure as ghost cells do in ghost cell glaucoma. A new clinical entity with the combination of these signs, namely, rhegmatogenous retinal detachment with "photoreceptor outer segment glaucoma" is designated as Schwartz-Matsuo syndrome in this report. The detection of photoreceptor outer segments in the anterior chamber indicates that a communication between subretinal space and aqueous humor has been established by some mechanism. The new syndrome should be included in differential diagnoses of iritis and glaucoma.

Variable indenter to modify indentation during biomicroscopy of the peripheral fundus

A modified scleral indentation attachment to the Goldmann three-mirror lens permitted visualization of the same area with and without indentation. Intraocular pressure increased only at the time of indentation. A plastic funnel replaced the metal one, thus reducing the entry of air bubbles between the glass and cornea.
