The Eyes Have It (TEHI) app is designed to teach medical and optometric students, and to assist physicians, optometrists, ophthalmic technicians, nurses and other health care providers in diagnosing and managing eye care problems. Written by respected University of Michigan ophthalmologist Jonathan D. Trobe, MD, the text contains hyperlinks to supplemental images, narrated animations, and videos that illustrate the clinical and teaching points. A picture-based multiple-choice quiz allows users to assess their knowledge. With 134 eye conditions, 410 images, more than 40 narrated animations and patient videos, 6 screening examination videos and an eye anatomy review section, this pocket resource can be your go-to source for eye information! A quiz of multiple-choice questions allows users to test themselves on their knowledge of eye conditions and their management.
