Extract

The widespread use of smartphones provides a unique opportunity for telemedicine. In ophthalmology, smartphones are used for visual acuity assessments and to document examinations, particularly in settings like the emergency department, where the usual ophthalmic tools and photographic services are unavailable.1 However, to our knowledge, these devices have not been used for systematic, remote review of clinical photographs in ophthalmology as they have in radiology and dermatology.2- 3 We performed a pilot investigation to compare the quality of nonmydriatic fundus photographs displayed on an iPhone 3G (Apple Inc) vs a desktop computer.
