My Daddy is seeing grid patterns and honeycomb patterns

[ridewine]

My Daddy has glaucoma which has been managed for 50 + years. He has had surgeries for cataracts, glaucoma, etc.
He is 83 years old.

He is now seeing grids when he looks at things. They go from grids to honeycombs shape. He has talked to his opthamologist, family doctor, neurologist, no ones has ever heard of this problem. They tell him they will do some research but they have no answer.
PLEASE has anyone ever had these symptons? PLEASE!!!

Thank you very much.       Joanne

I see the same thing as your dad. Just got back from an ophthalmologist who said that it is not a problem with my eyes but with how my brain is interpreting the pictures my eyes are taking.I just read an article on the Internet saying that research has shown that anastesia can cause visual hallucinations in the form of grid patterns. Google try googling: neurology and grid patterns. I started seeing the yellow, honeycomb grids after having a hysterectomy.

I have just started seeing the honeycomb patterns on the ceilings and walls when I first wake up, they are perfect in shape and quite amazing really.  But my very first images were like green lazer beams in a perfect grid pattern. I've also had a hysterectomy, but that was two years ago.  I would love to know what is causing this.

There are several things considered on this discussion and elsewhere. If major pathology of the eye especially the macula it should be there all or most of the time. An eye MD exam with macular OCT should detect this problem. If just when awake (long thread on this) and goes away quickly its usually just the eye shifting from dark adaptation to light adaptation. If comes in spells lasting 5-30+minutes and can be seen with eye shut its often eye (ophthalmic migraine) or TIA (transient ischemic attack)

For completeness sake in rare instances it would be atypical seizure disorder like temporal lobe focus

Too many causes to give you a specific reason. Could be due to eye problem, glasses problem or just the stress of driving. JCH MD

Dr. Hagan I have a lot of confidence in your opinion, so I would like to ask you another question.
My eyes tire easily when I am driving, what can cause this?

I think the dot/honeycomb pattern I see sometimes is related to my extensive computer use, the pattern looks like pixels from a computer screen, and they go away. My overall vision is very clear.
Can overuse of a computer cause something like this?

[islandgirl1947]

would a person that has macular degeneration see a dotted pattern in both eyes.

[islandgirl1947]

Not a blind spot just a dotted pattern. My central vision is clear.

[islandgirl1947]

Please disregard the emails, I have my answer. Do not answer these two.

[JohnHaganMD]

As a generalization I would say that is correct. If something new, different and concerning develops then a repeat exam would be required. JCH MD

I have had an eye exam just a few months ago and the doctor said everything was fine, no macular degeneration or glacoma or anything like that, just an astigmatism change.
So as long as the after image goes away I shouldn't have anything to worry about. Correct?
