To propose the objectives of undergraduate training in direct ophthalmoscopy (DO).
Narrative review of the literature on (i) opinions about the expected proficiency from students in DO, and (ii) estimates of its diagnostic value.
(i) Authorities disagree on the proficiency in DO that they expect from students. Textbooks of physical diagnosis differ in their coverage of DO. Surveys have indicated that US physicians expect students to be able to detect optic nerve head abnormalities. The Association of American Medical Colleges expects students to perform ophthalmoscopic examination and describe observations. The International Council of Ophthalmology expects students to recognize also diabetic and hypertensive retinopathies. The Association of University Professors in Ophthalmology requires that students recognize papilloedema, cholesterol emboli, glaucomatous cupping and macular degeneration. (ii) There is evidence that DO, even by ophthalmologists, is inadequate for screening for glaucoma, diabetic and hypertensive retinopathies. Two studies have suggested a limited value of DO in detecting clinical emergencies.
The evidence that DO, even by ophthalmologists, is sub-optimal in detecting common abnormalities challenges existing the notions of training medical students. On pending the results of additional studies of the value of DO in detecting emergencies, we suggest that undergraduate teaching of DO should impart the following: (i) an ability to identify the red fundus reflex and optic disc; (ii) an ability to recognize signs of clinical emergencies in patients, mannequins or fundus photographs; and (iii) knowledge about, but not an ability to detect, other retinopathies.
提出直接检眼镜(DO)本科培训的目标。
对(i)关于学生在 DO 方面预期熟练程度的意见,以及(ii)对其诊断价值的估计的文献进行叙述性综述。
(i)权威机构对学生在 DO 方面的熟练程度存在分歧。物理诊断教科书在 DO 的涵盖范围上有所不同。调查表明,美国医生希望学生能够发现视神经头异常。美国医学协会希望学生能够进行眼科检查并描述观察结果。国际眼科理事会希望学生也能识别糖尿病和高血压性视网膜病变。大学眼科教授协会要求学生识别视乳头水肿、胆固醇栓塞、青光眼杯和黄斑变性。(ii)有证据表明,即使是眼科医生进行的 DO 检查也不足以筛查青光眼、糖尿病和高血压性视网膜病变。有两项研究表明 DO 在检测临床急症方面的价值有限。
有证据表明,即使是眼科医生进行的 DO 检查在检测常见异常方面也不理想,这对现有的培训医学生的观念提出了挑战。在等待 DO 在检测急症方面的额外研究结果的同时,我们建议本科 DO 教学应传授以下内容:(i)能够识别红色眼底反射和视盘;(ii)能够在患者、人体模型或眼底照片中识别临床急症的迹象;(iii)了解但不具备检测其他视网膜病变的能力。
