DRISTI -
Diabetic Retinopathy Identification Software for
Timely Intervention
Diabetic Retinopathy (DR) is
the damage caused to retina by complications of
diabetes which can eventually lead to blindness.
Proper and systematic screening for DR have been
shown to be effective in prevention and
management of DR.
However, in developing
countries like India there is an enormous
disparity in ratio between trained
ophthalmologists to patients which makes
screening programs less effective. Computer
Aided Detection can play a pivotal role in
addressing prevention of avoidable blindness by
increasing screening efficiency of DR.
DRISTI, using quantitative
image analysis algorithms, analyses retinal
fundus images for DR lesions and directs DR
suspicious cases for detailed ophthalmologist's
review. Most of the DR negative cases are
screened out without an ophthalmologist's
intervention.
