Alzheimer’s Detection In The Eye

altzheimer1There are many devastating diseases of aging like hypertension, diabetes and heart disease. However, none impacts the family quite as much as the emotional and psychological impact of Alzheimer’s disease.    

A relatively new eye scan instrument called an OCT –  OcularOCT machineCoherence Tomography – has been used to evaluate glaucoma, macular degeneration and retinal holes and detachments. Now, researchers have determined a connection between OCT results and early Alzheimer’s detection.

Early detection can help with early treatments – though treatments are far less than medicine would like. However, early detection would help in early diagnosis and provide for life’s adjustment in a more comfortable fashion – both for the patient and for developing family support.

Though very technical, the OCT instrument scans the back of the eye in real time. The entire process takes less than 1 minute and requires no drops or medicines to perform.

Below is an image created by the OCT of a detailed picture of the retina at the back of the eye.  Deposits in the retina (drusen) or reduction of the number of transmission  nerve fiber layer may be indicators of oncoming Alzheimer’s.

Imre Lengyell, PhD discusses in this short video his thoughts over drusen and Alzheimer’s.

It is awesome that research continues not only in this ocular area but in all areas of medicine to discover causes, early detection and possible treatments for this horrific disease which strips a person of his cognitive abilities and yet physically he or she still lives.
