Did you know that we can even detect brain tumors from looking at your eyes? Tumors can produce a visual field loss (blind spot) which can tell us where in the brain the tumor may be located (like a road map basically). Although visual field loss is invisible to you, neurologically we can pick it up on testing. Your pupil size and reactivity to light can also tell us if you have a retinal detachment or a possible tumor. It is called an APD (Afferent Pupil Defect).
Pupils should always be equal round and reactive. Anisocoria is an unequal size pupil but can be normal. When the pupil is suddenly different in size that it becomes a concern. A chemical in your eye can also cause it to change but your pupil will go back to normal within a day or two. Any of the above should be investigated and followed.
Now let’s say you had a problem, red eye, painful, etc. and you saw the doctor. If everything has been examined and you have been given meds, you should start to improve in about three to four days on average. If not, something is wrong, we need to change meds or increase the dosage for your difficult case. This is a standard rule, and you should be followed closely by your eye doctor until you are better.
