Cause of Dry Macular Degeneration Discovered

Researchers in Montreal, Canada have identify the underlying cause of dry macular degeneration.  With the discovery of what causes dry macular degeneration, researchers are hopeful that new therapies and treatments can be developed for this eye disease.

Sainte-Justine Hospital and Universite de Montreal scientists said they now have a better understanding of processes that cause accumulations of lipids (fats) in the inner back of the eye (retina) which can lead to eye damage associated with macular degeneration.

“This discovery brings us one step closer to treating dry macular degeneration, which could significantly improve the quality of life of seniors who are most affected by this eye disease,” said Universite de Montreal professor and study co-author Huy Ong, PhD.

Currently, there is no cure for age-related macular degeneration.  Drug treatments are only available for the wet macular degeneration.  Treatment thus far for the dry macular degeneration involves dietary supplements of antioxidants which have been shown to slow the progression of the eye disease.

With an understanding of what causes dry macular degeneration, patients suffering from the most common form of this eye disease may have a brighter future as therapies and treatments stem from this discovery.

Study results were published in the February issue of the medical journal PLoS Medicine.
