Diabetes is known to take its toll on the vision of the patient. Though most of the time the damage to vision may not be quick, with the passage of time, a diabetic is likely to feel the deterioration of vision.
Conditions such as cataracts, glaucoma or diabetic retinopathy are sometimes diagnosed in diabetics. Among these, diabetic retinopathy ( i.e. the unwanted growth of capillaries in the retina) is possibly considered a leading cause of vision loss among diabetics.
Hope for those diagnosed with diabetic retinopathy now comes from a team of scientists and engineers at the University of British Columbia. They have developed a new drug delivery device, which if planted deep in the eye socket can release the required drug for treatment on-demand by the body.
The study and design was led by PhD mechanical engineering graduate Fatemeh Nazly Pirmoradi and Mechanical Engineering Assoc. Prof. Mu Chiao.
