Regular Eye Exams Can Stop You Going Blind
Posted by Charlie Prost on December 15th, 2010
As a suburban Optometrist performing eye exams every day, you see a lot of normal healthy eyes. And then someone will come along that shakes you up a bit and reminds us all of the value of regular checkups.
Case 1: A 46 year old lady came in to have her children’s eyes tested. After a little persuasion, she had her eyes examined too. She wasn’t going to because she felt fine, nothing was bothering her about her vision and gee, life is busy! It had been three years since her last eye examination with me.
The glasses examination (refraction) was all very straight forward. She did have great vision on the letter chart. However, when I looked inside her eyes I noticed a classic pattern on her retinas that indicates loss of neural tissue.
We did a computerised Visual Field Analysis to confirm that she has already lost up to 15% of her peripheral vision to Glaucoma. Remember that she felt fine and hadn’t noticed anything wrong. Glaucoma is insidious in this way. You have to lose a lot of vision before you can tell anything is out of the ordinary.
An eye exam will detect these changes much earlier and help you to save your vision. Glaucoma is treatable, loss of vision is preventable.
Case 2: A 78 year old woman was brought in by her daughter for an eye exam after breaking her glasses. No-one was quite sure when her last checkup was and she insisted the old glasses were fine, they just needed fixing.
On covering her right eye, she kept moving her head away from the occluder paddle to see around it. She had no vision in her right eye and she had not noticed.
How does that happen? Most people usually use both eyes together and wouldn’t even think to check their vision in each eye separately. She had advanced cataract in the right eye and a medium level in the left eye. Fixing her glasses was unfortunately not going to help anything!
I referred her for cataract surgery to a local Ophthalmologist and now she has her vision back. She can read, watch tv and do the crosswords. What a difference! Why go blind when it can be so easily helped?
Case 3: A 42 year old man came in for a checkup and to get some reading glasses for the first time to help with seeing the fine print and on the computer.
During the examination, I noticed an interesting colored lump at the far edge of his iris (colored part of the eye). With a sinking feeling, the thought in my head was “Melanoma” Oh no.
Melanoma is a very active type of skin cancer that you can also get within the eye, at the front or at the back on the retina. As these lesions are usually detected quite late, it often means the eye needs to be removed.
I referred him for an ultrasound and photography of the lesion. We were both so pleased when it came back that it was only a mole. Just like moles on the skin, they require monitoring for changes to detect it quickly if it does turn cancerous. He now has annual eye exams to “keep an eye on it” and to keep his eye.
