Molecular medicine "could prevent sight loss"

The use of molecular medicine could help to prevent "catastrophic" vision loss in the planet"s adult population in the coming years, according to one expert in the field.

Dr Richer, director of Ocular Preventive Medicine and an Associate Professor, Family & Preventive Medicine, at the James A Lovell Federal Health Facility in Chicago, made the comments at International Conference on Recent Trends in Therapeutic Advancement of Free Radical Science, in Chennai, India.

According to the expert, molecular medicine using small molecules which pass through the blood-retinal barrier and influence genes are "very promising".

He noted that early studies have indicated that vision loss can be prevented in later years and eyesight can even be restored in patients with advanced macular degeneration.

Dr Richer explained: "I have now documented three consecutive cases where molecular medicine appears to have restored the normal architecture of the human retina and measurably improved visual function that could not be accomplished with conventional care."

In other research, a recent study published by the Kennedy Krieger Institute found that an unexpected biological pathway, which appears to contribute to the development of glaucoma and its resulting vision loss.
