Title: Smartphone-based Ophthalmic Examination System

Invention: This smartphone-based ophthalmic examination device is coupled with accessories and software applications for ocular diagnosis. This multi-operative device/system possesses many capabilities for preliminary ocular examinations namely; (bio-) microscope or opthalmoscope function, ophthalmic slit-lamp, a pupillometer, fundoscope, scheimpflug camera, and stereo imaging (stereo-photo) device. This device/system is intended to be portable and handheld as well as compatible with telemedicine.

Background: Ensuring clinical access to health care requires that mobile approaches be explored. Researchers at the U of A are developing a comprehensive smartphone-based ophthalmic examination device that is coupled with accessories and software applications for ocular diagnosis in remote or austere locations where ophthalmic or optometric support is unavailable.
