I'm hoping to get some help from other forum users about Argyll Robertson pupil. I've heard that it can be unilateral, but I'm not sure if that's true. Can anyone confirm this, or provide any additional information about the topic? Has anyone here had any experience with this condition? Any help would be greatly appreciated.

Can Argyll Robertson pupil be unilateral?

Yes, it can. An Argyll Robertson pupil is a type of pupil that is characterized by a small, irregularly shaped pupil that constricts in response to accommodation, but does not react to light. It is found most commonly in neurosyphilis, but can also be seen in other neurological diseases such as multiple sclerosis, Arnold-Chiari malformation, and tumors of the posterior hypothalamus. It can be unilateral or bilateral.

Yes, it is possible for an Argyll Robertson pupil (ARP) to be unilateral. This is a condition in which one pupil is constricted, while the other pupil is normal. It is usually caused by damage to the autonomic nervous system, and it can be seen in some cases of neurosyphilis, brain tumor, and other neurological conditions. Treatment for unilateral ARP usually involves treating the underlying condition, although some medications may also help to reduce the pupil's constriction.

The Argyll Robertson pupil (ARP) is a condition in which the eyes exhibit a small, irregular, and non-reactive pupil. It is most commonly associated with neurosyphilis, although it can also be seen in other neurological disorders. ARP can be unilateral, meaning it affects only one eye, or bilateral, meaning it affects both eyes. Therefore, the answer to the question is yes, the Argyll Robertson pupil can be unilateral.

Yes, an Argyll Robertson pupil can be unilateral if caused by conditions such as third nerve palsy, Horner syndrome, Adie syndrome, and other neurological diseases such as multiple sclerosis or stroke. Unilateral Argyll Robertson pupils may also be caused by certain medications or drugs such as antipsychotics, anticholinergics, and neostigmine. Generally, an Argyll Robertson pupil constricts maximally and reacts normally to light, but does not react to accommodation. This is a diagnostic sign of certain neurological diseases, so if a unilateral Argyll Robertson pupil is present, further testing should be done to determine the underlying cause.
