Will the change in size of the pupil subside on its own?

Question

Hello doctor,

I am around 38 years old and noticed a change in pupil size approximately six weeks ago. The doctor diagnosed physiological anisocoria and said there was a difference of 1 mm. But I have noticed the difference to be more on some days. What could be the reason for this? Will it subside on its own? Kindly help.

Hi,

Welcome to icliniq.com.

I understand your concern. Physiological anisocoria of one mm is normal. The size of the pupil keeps changing depending on the light exposure. Therefore, the correct method to check pupil size is scotopic pupil size which is checked by pentacam and other instruments in the dark. In case of doubt, we need to check afferent and efferent pupillary pathways. It is done by checking the direct and consensual pupillary response. We can check accommodation reflex and near reflex also. And if all of these are normal, then there is nothing to worry about. I hope this helps. Thank you.
