Abstract: Objective To evaluate the effectiveness of EYESI binocular indirect ophthalmoscope simulation training system (EYESI) as a training and assessment platform for indirect ophthalmoscope operation and fundus mapping skills of ophthalmic residents. Design Comparative teaching study. Participants Twenty residents in Ophthalmology Department. Methods  The participants were divided into 0 group, 1 month group, 3 month group and 6 month group according to the experience of using indirect ophthalmoscope. Participants finished the examination on EYESI to evaluate the effectiveness of the system as a method of assessment. Five of the residents were trained by this system. The training contents of operation and fundus mapping were completed for 2 weeks each. The results were compared with other 5 residents who received the traditional practice training for 2 months. Main Outcome Measures The operation or drawing time, light exposure time, drawing accuracy and total score. Results The length of operation time in group 0 was the longest (1359.25±729.82) s, while in other groups it decreased with the increase of experience. The longest time of light exposure was (442.00±188.79) s in group 0. The time of drawing fundus map decreased gradually with the increase of experience in indirect ophthalmoscope use. The longest drawing time of group 0 (1860.50±188.80) s and the drawing shortest time of group 6 month(968.75±336.58) s were significantly different (P=0.026). The operation time in EYESI training group decreased from (1226.67±832.76) s to (761.00±307.32) s, and the decreasing percentage was 30.58%±19.22%. However, the operation time in traditional practice training group decreased from (765.00±306.92) s to (595.67±158.71) s, and the decreasing percentage was 19.09%±12.87%. In EYESI training group the drawing time decreased from (1001.00±507.72) s to (667.00±333.75) s, and the decreasing percentage was 33.90%±1.46%. The accuracy of drawing increased from 81.28%±3.50% to 88.88%±1.45%, and the increasing percentage was 9.41%±2.93%. After two months of traditional practical training, the drawing time decreased from (1810.00±424.08) s to (1429.67±180.47) s, the shortening percentage was 19.40%±10.40%. The accuracy of drawing increased from 75.13%±11.29 % to 81.62%±10.31%, the increasing percentage was 15.59%±12.26%. Conclusion EYESI system is an effective and accurate platform for ophthalmologists to study indirect ophthalmoscopes.
