IntroductionWith declining exposure to the ophthalmologic examination in medical school, medical students and their instructors need a simple, effective method for teaching direct ophthalmoscopy.ObjectiveEvaluation of canisters as direct ophthalmoscopy teaching aids for medical students.MethodsTwo ounce plastic canisters were designed to simulate an eye with 35 mm fundus photographs placed at the base and an 8mm hole drilled in the center of the cap to simulate a dilated pupil. These tools were used as an optional supplement to the instruction of ophthalmoscopy. Participants included 102 second-year medical students from the Medical College of Wisconsin and 11 residents and instructors from The Eye Institute in Milwaukee, Wis.ResultsEffectiveness and ease of use of the canisters were assessed by analyzing questionnaires completed by the medical students and instructors. According to 76% of students and 93% of instructors, the canisters "supplemented their learning/teaching." Most students (90%) and instructors (88%) found them "easy to use."ConclusionThis device is a simple and effective tool for teaching direct ophthalmoscopy to medical students.
