As an eye care provider, you are well aware that the sun’s UV rays can damage your patients’ eyes, and this is why you have likely worked toward educating them on this premise. New research from Case Western Reserve University in Ohio has proven a correlation between cataracts and chronic exposure to UV. As the leading cause of blindness in the world, cataracts are expected to affect more than 50 million Americans, nearly double the current number, according to the National Eye Institute (NEI).
The study, which was partially funded by the NEI, has shown that UV light causes glycation. Glycation is the destruction of proteins in the eye, which is seen in both cataracts and cells that are damaged by oxidative stress. When the proteins in the lens of the eye are destroyed, a cataract is formed. The researchers confirmed the process using a mouse model.
Follow-up research is planned to delve deeper into the process for better understanding, but the hope is that the current research will help prevent some of these cases from occurring. And with proper patient education, backed up by sound research, eye care professionals can help patients avoid this ailment with the right …
