This teaches actual fundus pathology as well as the skill of creating the visual montage. The mannequin model is limited, however, in that only one examiner can be taught at a time. To simultaneously teach fundus pathology and direct ophthalmoscopy skills to groups of students, a partial occluder for use with projected fundus photographs was devised.
