Omega-3 may keep blindness at bay
New research suggests omega-3 fatty acids can help prevent retinopathy, an eye disease that can lead to blindness in premature babies and people with diabetes.
Retinopathy causes abnormal blood vessels to grow in the retina, the light-sensitive tissue lining the inner surface of the eye.
This growth can cause the retina to detach from the back of the eye leading to vision loss.
"For people who have had diabetes for 25 years, more than half of them will have retinopathy," says Dr Lois Smith, a professor of ophthalmology at the Harvard Medical School .
