iExaminer for iPhone 4 Liberates Fundus Exams

Ophthalmoscopes are widely used to help diagnose a variety of conditions, but much like traditional microscopes they can only be used by one person at a time and sharing what one sees requires, as the old saying goes, a thousand words.

The iExaminer from Intuitive Medical Technologies in Shreveport, Louisiana is a simple iPhone 4 attachment for the (Read more...)

iPhone-Based Device Monitors Macular Degeneration

A new iPhone app could enable patients with degenerative eye diseases to track their vision loss at home. Known as myVisionTrack, the technology allows patients with diabetic retinopathy or macular degeneration to accurately check their vision in less than 90 seconds, according to its developers. myVisionTrack is designed specifically to treat pati (Read more...)

Gold and Lasers May Help Restore Vision to Many

At Australia’s Swinburne University of Technology research is underway to develop a method of activating optic nerves by laser stimulation.  The idea is to embed gold nanoparticles within the eye that can then be excited by lasers from within a pair of glasses.  If successful, this technology will help people suffering from eye diseases like (Read more...)

San Francisco Artist Seeks Funding for a Prosthetic Eye Camera

Tanya Vlach, a San Francisco based artist, lost her left eye in a car accident in 2005. She was given an ocular prosthesis to use, however, the prosthetic eye offers only cosmetic benefits since it’s just a dumb device meant to look like an eye.

Fascinated by advances in medical technology, she researched possible solutions to make her artificial e (Read more...)

Pediatric Vision Scanner Detects “Lazy Eye” Earlier

Lazy eye, or ambylopia, is the leading cause of vision loss in childhood, but it can be difficult to detect in small children who are unable to reliably use eye charts.  A new handheld scanning device identifies this ocular anomaly at the early stages, when it can be treated most effectively.

The test, which incorporates a low-power laser and takes (Read more...)

Frugal Solution to Cataract Diagnosis in Remote Places

Researchers at MIT have developed a cheap and easy to use system, called Catra, that uses a cameraphone clip-on device to map out cataracts.

The technology functions by sweeping the eye with a beam of light and using the phone’s camera to detect fuzzy spots. It can provide both a map of the cataracts and maybe help make an overall assessment (Read more...)

Bioengineering Students Create Device to Diagnose Dry Eyes

Keratoconjunctivitis sicca, better known as “dry eye”, is an annoying and sometimes painful condition in which the eyes often itch and burn because a person cannot produce sufficient tears to bathe and cool the eyes. Ophthalmologists usually diagnose dry eye through a series of tests that often analyze the tear fluid and its interaction (Read more...)
