Question 1

what causes anisocoria?

Accepted Answer

Need to: Eliminate adie's and argyll-robertson pupil (formner reacts, does not accomodate, the latter the opposite), but elevated intercranial pressure. Parasympathetics constrict the pupil, sympathetics dilate it. Overaction of one on one eye will make the size of the pupile vary.

Question 2

what causes anisocoria to occur?

Accepted Answer

Several things.: Anisocoria is when one pupil is larger than the other. Anisocoria may be congenital, caused by lesions in the brain or eye or induced by asymmetric topical application of meds. I believe david bowie has congenital anisocoria.

Question 3

what causes alternating anisocoria?

Accepted Answer

Medications: I believe this is probably medications either deliberately or unintentionally being placed in the eye. Sometimes pulmonary meds or powders can inadvertently get in the eyes... It only takes a small amount.

Question 4

how do i know if i have anisocoria?

Accepted Answer

Anisocoria: Measure the size of both pupils in the dark and under bright light conditions

Question 5

is there a way to manage anisocoria?

Accepted Answer

Yes, sometimes: I have found that some patients respond to dilute Pilocarpine drops for anisocoria, but it depends on the underlying cause of the condition.

Question 6

what are the signs of having anisocoria?

Accepted Answer

Anisocoria: One pupil smaller or larger than the other. If accompanied by confusion & severe headache, suspect brain lesion.

Question 7

could anisocoria be concealed with colored lenses?

Accepted Answer

Yes: Cosmetic contact lenses are available to mask both anisocoria and aniridia. An eyemd can guide you on where to find them!

Question 8

what are problems to look for if someone has anisocoria?

Accepted Answer

Droopy lid: ...(horner's syndrome) how long it's been there (congenital rarely a problem), double vision (could be third nerve palsy).

Question 9

can aneurisme cause seesaw anisocoria that comes and goes? or would aneurisme cause constant singlesided anisocoria?

Accepted Answer

If you have: true anisocoria, this is a sign of serious disease.   Get to a doctor immediately.  Anisocoria is unequal pupil size, so it is one sided by definition.

Question 10

if anisocoria is physiologic, is it normal for it to occur spontaneously in adulthood? is it common for the discrepancy to increase in dim light?

Accepted Answer

Anisocoria: Yes possible but must be rare if greater than 1 mm which would be hard to detect in most folks. What does your Dr. think is going on? There is a good discussion at Wikipedia.
