Abstract

Photostress testing can provide information not visible by ophthalmoscopy and can be used to detect early macular disease and possibly detect recovery prior to visual improvement.¹ Recovery times have been variable even in groups of age-matched normals.^{2 3} Macular photostress recovery tests must be reproducible, easy to perform with good patient compliance, and require a minimal amount of time and space. We report our experience with a new instrument designed by one of the authors (PB), testing 90 normal individuals and groups of patients with drusen, macular degeneration or diabetic retinopathy.
