  • Abstract
  • Look Inside

Utilizing the optics of hand fundus camera, a wide angle direct ophthalmoscope (30° view-ing angle) was built and clinical trial has been performed. This monocular portable ophthalmo-scope has 6 times as wide a field as regular direct ophthalmoscope (12° viewing angle), and it can eliminate corneal and lens reflexes. It was found that this ophthalmoscope had a capa-bility to review widely extended fundus lesions more easily and precisely.
