Alzheimer’s disease is a type of dementia, which distorts the function of the brain and gradually affects the thinking and memory of the affected person. It is common among people who are above the age of 60. This disease can affect every aspect of a person’s life such that it can cause visual problems.

Alzheimer’s affects the brain and the way it interprets images being seen by the eyes. This leads to misinterpretation of images which can pose a safety risk as well as create other visual problems in the following ways:-

  • Problems of correctly identifying things or people being seen.
  • Problems recognising colours in the blue-violet range.
  • Decreased peripheral vision. This means reduced side vision. People with Alzheimer’s will most likely not notice objects opposite them. This results in bumping into or falling over things when walking.
  • Loss of depth perception. This means an inability to distinguish between flat pictures and three-dimensional objects and/or problems calculating distances with the eyes.

 Diagnosing Alzheimer’s visual related problems

Alzheimer’s changes the way the light that gets into the eyes reflects off the retina. This can be identified when a comprehensive eye test is carried out on the patient. Early diagnosis will decrease the risk of developing additional vision problems and will also help in the proper management of current eye conditions.

Managing your eyesight after diagnosis

Going for your routine eye exams as recommended by your eye doctor is an important step to managing your eyesight after being diagnosed with the disease. Comprehensive eye exams will help to monitor your vision and enable your doctor to give you the right treatment plan per time to slow down the progression of the disease.

Also, living a consistently healthy lifestyle is key for Alzheimer’s disease patients. A healthy diet comprising mainly of fresh vegetables and lean protein, engaging in safe, regular exercises are all recommended for healthy eyes.
