Risperidone-related bilateral cystoid macular edema: a case report.

Background: A report of the second known case of bilateral cystoid macular edema in a patient taking risperidone.

Case Presentation: We report a case of a 69-year-old African American woman using risperidone who presented with worsening visual acuity and was found to have bilateral cystoid macular edema. Upon decreasing the dosage of risperidone, the cystoid macular edema resolved and visual acuity markedly improved.

Variability of measurement of retinal vessel diameters.

Purpose: To examine the effects of various cardiovascular, ocular, and lifestyle factors on retinal vessel diameters over short periods of time.

Methods: Subjects were invited to have photographs of their retina taken at each of three study visits. The same eye was photographed each time.
