Injections Improve Macular Edema Treatment


New research shows that supplementing laser eye treatment with eye injections can significantly improve vision in patients with diabetic macular edema. Researchers found that patients who had been given ranibizumab eye injections were able to read smaller type at a greater distance, allowing them to better perform in a standard optician's eye exam.

Ranibizumab injections halt chemical signals that cause blood vessels to grow in the eye, thus eliminating one of the causes of macular edema - faulty blood vessels leaking into tissue around the retina known as the macular. Researchers studied the eye health of 691 patients and found that patients, with diabetic macular edema, were up to 50% more likely to experience significantly improved vision following treatment involving both injections and laser therapy.

Researchers hope that their findings will lead to better treatment of diabetic macular edema - a condition that is affecting a growing number of people worldwide. The researchers will be continuing this study for a further three years in order to fully ascertain how effective the treatment remains after time has elapsed.
