Scleral depression

Abstract

Indirect ophthalmoscopic examination of the peripheral retina is greatly enhanced through the use of scleral indentation. This procedure enables the examiner to better diagnose and manage peripheral retinal anomalies. In this study, the anatomical landmarks and structures relevant to examination of the peripheral fundus are reviewed, along with the various types of instrumentation used in performing scleral indentation. The mechanical techniques used in scleral indentation are discussed as are many of the common errors committed by those learning to perform this procedure. Scleral indentation can be especially valuable in determining the exact nature of lesions noted in the retinal periphery. Case studies in which this procedure was vital to reaching an accurate diagnosis have been included.
