Researchers bring to light tooth-enamel content in eyes with dry AMD

NEI (National Eye Institute) researchers have come up with this starling discovery that a protein which deposits mineral enriched calcium in tooth enamel may also come under scrutiny for calcium deposits at the back of the eye in people with dry Age Related Macular degeneration (AMD). The protein named Amelotin may be the cause for the eye-sight impairment disease. This was a find published by NEI, a part of National Institutes of Health.

Considering a cross-section of an epithelial cells for observation, it was found that mineral rich calcium content, Amelotin responsible for tooth enamel deposited itself in the back of the eye due to stress of some kind. It was also corroborated by the chief of Molecular Structure and Functional Genomics that this deposit was also visible on the back of the eyes of a human donor with dry AMD.

The research states that there are two types of AMD-wet and dry. Wet AMD can be slowed down but there are no treatments still consistent with dry AMD. Dry AMD is also called geographic atrophy. Dry AMD comprises content of cholesterol, lipids, proteins and minerals that are gathered at the back of the eye.  A few of them are called Soft Drusen that are acutely different from deposits that are found dispersed in wet AMD.

New has it that, researchers found a calcium rich mineral compound called hydroxyapatite (HAP) in dry AMD deposits. HAP is a principal ingredient of tooth enamel and bone.
