Summary

The scleral depressed exam is an important routine technique for evaluating the retinal periphery for various reasons. During such examination, an instrument is used to bring the anterior part of the retina in the field of view of the physician. The downside of this examination technique is the patient discomfort. Different instruments can be used to do depress the sclera. The objective of our research is to compare three commonly used scleral depressor based on their performance for the ophthalmologist and their subjectively induced discomfort. Patients will be randomly allocated to one of the 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

Who is the study for?

This trial is for individuals who need a retinal examination, which involves pressing on the eye's surface (sclera) to view the retina. Participants must be comfortable with random assignment to have one of their eyes tested with either a Schocket scleral depressor, Josephberg-Besser scleral depressor, or cotton tip applicator.

What is being tested?

The study aims to compare three tools used in eye exams: Schocket and Josephberg-Besser scleral depressors, and cotton tip applicators. Patients will have different tools used on each eye randomly to determine which causes less discomfort while being effective for the doctor.

What are the potential side effects?

Potential side effects may include discomfort or pain in the eyes during or after using any of these instruments. The severity can vary depending on individual sensitivity and reaction to pressure applied by each tool.
