Does anyone have experience of an Adie’s pupil (pupil is abnormally large and does not constrict in response to light). I have been told mine is due to MS. My vision in the affected eye is increasingly blurry, but no optic neuritis in the affected eye (although I have optic neuritis in the other eye).

I understood that MS is caused by demyelination, and I've seen quite a few lists of MS symptoms, including some rare ones, I've never seen Adie's eye listed anywhere. So maybe no connection?
Wishing everyone a great day with a cure for our MS not too far away!! 💕 😊

Vision problems can manifest differently in people with MS. Since you're experiencing blurry vision and pupil issues, it's important to have these symptoms evaluated by both your neurologist and a neuro-ophthalmologist - a specialist who focuses specifically on neurological disorders affecting the eyes.

Vision problems can manifest differently in people with MS. Since you're experiencing blurry vision and pupil issues, it's important to have these symptoms evaluated by both your neurologist and a neuro-ophthalmologist - a specialist who focuses specifically on neurological disorders affecting the eyes.

MS can affect vision in multiple ways, and symptoms may vary between eyes. While you mention having optic neuritis in one eye, the blurriness in your other eye should be monitored closely to ensure appropriate treatment. Common MS-related vision symptoms can include:
• Double vision (diplopia)
• Uncontrolled eye movements (nystagmus)
• Eye floaters
• Changes in color perception
• Blurred vision
• Light sensitivity

It's crucial to report any new or changing vision symptoms to your healthcare team, as they can help track disease progression and adjust treatment plans accordingly.
