Construct and face validity of the eyesi indirect ophthalmoscope simulator

Purpose: To evaluate construct and face validity of the Eyesi Binocular Indirect Ophthalmoscope Simulator. Methods: The performance of 25 medical students (Group A) was compared with that of 17 ophthalmology and optometry trainees (Group B) on the Eyesi Binocular Indirect Ophthalmoscope Simulator. During the course of a single session, each participant viewed an orientation module followed by an instruction session and a demonstration case, and performed 6 cases of progressively increasing difficulty (4 levels) and a 10-question face validity questionnaire. Outcomes included total score, total examination time, percent retina examined, and duration of eye exposure to light. Results: Group B achieved significantly better total scores than Group A on all difficulty levels (P = 0.02, P = 0.001, P = 0.001, and P = 0.0001, for Levels 1–4, respectively) and had a significantly faster mean duration of examination (8 minutes 58 seconds vs. 5 minutes 21 seconds, P
