Title: Smartphone-Based Handheld Ophthalmic Examination Device

Invention: Researchers at the University of Arizona have developed a comprehensive ophthalmic system with a handheld smartphone-based examination device for ocular diagnosis that uniquely monitors of both eyes to detect disease, drug use or fatigue. This multi-operative device/system possesses many capabilities for preliminary ocular examinations namely; (bio-) microscope or ophthalmoscope function, ophthalmic slit-lamp, a pupillometer, fundoscope, scheimpflug camera, and stereo imaging (stereo-photo) device. This invention is a portable, hand-held, device/system that is compatible with medicine-related telecommunication.

Background: The ability to provide standard examination procedures in a setting outside a clinic has become an increasing technological trend. Not everyone has access to clinical care and, as a result, it is pertinent to explore more mobile approaches to health care.  Demand for mobile medical devices is therefore increasing and is highly applicable in at-home care, space, military forward operating bases, ships afloat, disaster areas, on-field sporting events, and/or humanitarian missions.

 

Applications:

  • Fundoscopy/fundus cameras
  • Pupillometry
  • Macro and micro imaging of ocular surfaces and interior structures
  • Slit-lamps
  • Scheimflug imaging
  • Use outside a clinical setting

 

Advantages:

  • Portable and hand-held
  • Telecommunication aids in early diagnosis of ocular conditions
  • Applicable to a variety of clinical fields
