This term describes a temporary anisocoria that resolves on its own and may be caused by benign conditions such as a migraine headache, especially when there are no other associated symptoms present. Aberrant regeneration of the oculomotor cranial nerve.Autonomic neuropathies such as those as a result of diabetes or a vitamin B12 deficiency.Tonic pupilĪ tonic pupil is one that responds poorly to light stimuli but briskly when focusing on nearby objects and the position of the pupil is maintained for a prolonged period, thus the description of the pupil being tonic.Ĭonditions associated with this situation include: The clinical presentation of acute angle closure includes pain, edema of the cornea, increased intra-ocular pressure, and a light-fixed mid-position pupil. Acute angle closure causes a sudden rise in intraocular pressure and is a very important cause of mechanical dysfunction of the iris that leads to poor reactivity of the pupil. Mechanical damageĭamage to the muscle of the iris itself due to trauma, infection, or even surgery may result in anisocoria. The pupil here will fail to respond to light stimuli and the rest of the examination won't yield any other abnormalities involving the anatomy and function of the affected eye. If one pupil is involved then the condition is referred to as pharmacological anisocoria. The accidental or intentional administration or instillation of atropine, or atropine-like medications, can cause dilatation of one or both pupils. ![]() Out of all the causes of anisocoria, a pharmacologically induced dilatation of the pupil is the largest in this scenario. Therefore, the affected side is the one where the pupil remains open despite stimulation to light. The side of the brain where the oculomotor nerve palsy occurs results in a pupil that remains dilated (mydriatic) and is poorly reactive to light. Oculomotor (third) nerve palsy that affects the dilation of the pupil is often caused by compressive issues in the area of the brain where the nerve is located. ![]() Together with anisocoria, the signs and symptoms of Horner syndrome include a decreased pupil size (miosis), a drooping eyelid (ptosis), and decreased sweating (anhidrosis) all involving the affected side.
