A simple eye model for practicing indirect ophthalmoscopy and retinal laser photocoagulation

摘要

Purpose—To describe a simple and inexpensive model eye that allows lifelike simulation of indirect oph‐thalmoscopy and retinal photocoagulation.Methods—A 60 D examination lens, a bulb syringe, foam poster-board, a manila folder, a hobby knife, afine pair of scissors, a glue gun, and a 2.5 cm square Optos color fundus photograph printed at 1200 dpiresolution on glossy photographic paper were used to create a model eye.Results—This model produces a high-quality, inverted, and aerial image that closely simulates clinicalindirect ophthalmoscopy. Pupil size and retinal pathology can be easily changed. Binocular indirect laserphotocoagulation can also be simulated, because white laser burns will appear on the glossy inkjet photo‐graph.Conclusions—Binocular indirect ophthalmoscopy and indirect laser photocoagulation are technicallychallenging diagnostic and therapeutic techniques. This simple and easy-to-build eye model allows for life‐like simulation of indirect ophthalmoscopy and indirect laser retinal photocoagulation.
