“For the first time, we have been able to connect these specific high-risk cardiovascular diseases to a specific form of AMD, the one with subretinal drusenoid deposits (SDDs),” explains lead creator R. Theodore Smith, MD, PhD, Professor of Ophthalmology on the Icahn School of Medicine at Mount Sinai. “This study is the first strong link between the leading cause of blindness, AMD, and heart disease, the leading cause of death worldwide. Furthermore, we also have strong evidence for what actually happens: the blood supply to the eye is directly diminished by these diseases, either by heart damage that diminishes blood supply throughout the body, or from a blocked carotid artery that directly impedes blood flow to the eye. A poor blood supply can cause damage to any part of the body, and with these specific diseases, the destroyed retina and leftover SDDs are that damage. Retinal damage means vision loss, and can lead to blindness”.

In this examine, researchers analyzed the eyes of 200 AMD sufferers and requested them to reply a questionnaire about their historical past of coronary heart illness. Of the 200 sufferers, 97 had deposits within the sub-retinal area of the eyes (subretinal drusenoid deposits (SDDs)) and 103 had drusen within the retinal area. Forty-seven of the 200 had extreme coronary heart illness (19 had coronary heart injury from coronary heart failure or coronary heart assault, 17 critical valve illness, and 11 stroke stemming from the carotid artery). Forty of the 47 (86 p.c) had SDDs. The researchers concluded that AMD sufferers with these extreme cardiovascular ailments and stroke have been 9 occasions extra more likely to have SDDs than these with out them (1 Trusted Source
