A member asked:

Is pupil dilitation normal to happen if you have meoobiam gland dysfunction? my right pupil gets huge when the oil comes down my eye

A doctor has provided 1 answer

Cyclical Mydriasis: The pupil is innervated by the inferior branch of the third cranial nerve and the nasociliary nerve. The meibomian glands are oil secreting glands in the lids which acts as a surfactant to stabilize the tear film. Cyclical migraine and pharmacologic dilation are more likely than a Horner's or Adie's pupil, but need to exclude a CN III lesion. See a neuro-ophthalmologist for a definitive diagnosis.
