Summary

The scleral depression exam is an important routine technique for evaluating the retinal periphery for various reasons. During this examination, an instrument is used to bring the anterior part of the retina into the physician's field of view. The downside of this technique is the discomfort it may cause the patient. Different instruments can be used to depress the sclera.

The objective of this research is to compare three commonly used scleral depressors based on their performance for the ophthalmologist and the discomfort they subjectively induce in patients.

Patients will be randomly allocated to one of three examination groups:

Group A: One eye examined with the Schocket scleral depressor, the other eye with the Josephberg-Besser scleral depressor.

Group B: One eye examined with the Schocket scleral depressor, the other eye with the cotton-tip applicator.

Group C: One eye examined with the cotton-tip applicator, the other eye with the Josephberg-Besser scleral depressor.
