I had a bad case of optic neuritis in my eye a year ago w/ ms. I notice that pupil is almost always dilated larger still. Normal? Or cause for concern
Dilated pupil. Presumably what happened is that you sustained optic nerve damage & the nerve is not transmitting enough light data to tell the pupil to contract more. The "afferent limb" of the "direct" light reflex is damaged. If a light shined in your other eye causes the dilated pupil to contract, then the "consensual" light reflex is intact. That's called a Marcus-Gunn pupil.
Not surprising. Your eye likely still displays what is called an afferent pupillary defect, and dilates with light exposure. Do not be alarmed. But, if you have a diagnosis of MS, why do you not list an MS disease modifying agent, which would be critical in controlling future issues? Do you not have a neurologist who focuses in MS??
