To evaluate the effectiveness of smartphone ophthalmoscope (SO) in teaching ophthalmoscopy, compared with direct ophthalmoscope (DO). In this cross-over study, 45 final-year medical students attending sessions at a single institution were randomly allocated to two groups (A and B). Both groups attended two training sessions. In the first session, Group A students were taught ophthalmoscopy using DO and Group B students using SO. In the second session, the training sessions were crossed over. A series of eye models with 10 letters placed on the inner surface were designed to assess the students' skill on ophthalmoscopy. Students performed ophthalmoscopy on the eye models, recorded their findings, and completed a questionnaire of feedback on DO and SO. The main outcome measure was the score of ophthalmoscopy, assessed by the student correctly recording each letter (score 1 for each letter). For Group A, the mean score of ophthalmoscopy on the eye model using DO and SO was 3.9±2.4 and 8.2±2.2, respectively. For Group B, the mean score of ophthalmoscopy on the eye model using SO and DO 8.7±1.8 and 5.7±3.5 . Students scored significantly higher in ophthalmoscopy when using SO than DO (<0.001). They expressed better visualization of the fundus using SO than DO (4.49±0.65 vs 4.13±0.81, =0.004). Students' performance of ophthalmoscopy was better when SO was used compared with DO. The use of SO as an adjunctive tool is recommended to improve the effectiveness of teaching ophthalmoscopy.
为了评估智能手机检眼镜（SO）在眼科检查教学中的有效性，与直接检眼镜（DO）进行比较。在这项交叉研究中，45 名在一个机构参加课程的最后一年医学生被随机分配到两组（A 组和 B 组）。两组都参加了两个培训课程。在第一节课中，A 组学生使用 DO 进行检眼镜教学，B 组学生使用 SO 进行教学。在第二节课中，培训课程进行了交叉。设计了一系列带有 10 个字母的眼模型，放置在内表面上，以评估学生的检眼镜技能。学生在眼模型上进行检眼镜检查，记录他们的发现，并完成关于 DO 和 SO 的反馈问卷。主要观察指标是检眼镜的评分，通过学生正确记录每个字母来评估（每个字母得 1 分）。对于 A 组，使用 DO 和 SO 在眼模型上进行检眼镜的平均得分为 3.9±2.4 和 8.2±2.2。对于 B 组，使用 SO 和 DO 在眼模型上进行检眼镜的平均得分为 8.7±1.8 和 5.7±3.5。学生使用 SO 进行检眼镜检查的得分明显高于 DO（<0.001）。他们表示使用 SO 比 DO 更好地观察眼底（4.49±0.65 比 4.13±0.81，=0.004）。与 DO 相比，学生使用 SO 进行检眼镜检查的表现更好。建议将 SO 用作辅助工具，以提高眼科检查教学的效果。
