New technique can detect human eye diseases early

Updated on: 28-Dec-2016
With the coming of new technologies, a software analysis can now highlight the subtle differences between a diseased and healthy retina.

Researchers have developed a new technique that shows promise of early detection of diseases of the human eye and could also help design a smart phone based retinal diagnostic app. New technique can detect human eye diseases early


Optical coherence tomography (OCT) is a non invasive imaging test that enables physicians to monitor alterations in the thickness of the retinal layer as disease progresses in the human retina.

Researchers at IISER Kolkata, L.V. Prasad Eye Institute in Hyderabad and Bhabha Atomic Research Centre in Mumbai have developed a software analysis that was able to parse through the differences between a healthy retina and retinal layers of diabetic macular edema (DME) subjects from OCT images.

N.K. Das, IISER Kolkata says, "However, subtle changes in the retinal layers due to early disease progression are often not discernible. Our analysis can overcome that drawback and pinpoint early disease progression. The software can directly tell us."

N.K. Das also says,"In the future, we can develop affordable and portable devices for early detection, including a smart-phone app where images can be fed through an optic fibre."
