RESUMO
A series of 22 patients with crystals in the anterior segment of the eye was examined by specular microscopy. Of 10 patients with hypermature cataract and hyperrefringent bodies in the anterior chamber cholesterol crystals were identified in four patients and in six of the 10 in whom aspirate was obtained cholesterol crystals were demonstrated in three, two of these having shown crystals on specular microscopy. In 10 patients with intracorneal crystalline deposits, cholesterol crystals were found on specular microscopy, including one case of Schnyder's crystalline corneal dystrophy. Of two patients with multiple myeloma, corneal crystals were demonstrated in one. Crystals of the anterior segment of the eye are most likely to be cholesterol, and identification is important for future treatment.

The Pocklington (Keeler-Konan) wide field specular microscope has been in use for 18 months at the Corneal Diseases Unit, The Royal Victorian Eye and Ear Hospital, Melbourne. In this study, the microscope has been applied clinically to assess the state of the corneal endothelium and to evaluate comparative endothelial cell density and morphology in certain anterior segment microsurgical procedures. The clinical conditions studied are primary posterior chamber intraocular lens implantation, secondary intraocular lens implantation, intraocular lens exchange, and penetrating keratoplasty.

A clinical study of posterior corneal rings in human eyes was undertaken using the Pocklington (Keeler-Konan) contact wide field specular microscope designed by Sherrard. The method used to reproduce identical posterior corneal rings in the same human cornea, in vivo, using the contact wide field specular microscope camera, without the aid of a contact lens, is described. The technique enables the clinician to relocate and evaluate a selected area of human endothelial cells in the same eye.
