Pupil Abnormalities

Pupil abnormalities refer to changes in the size or reaction of the pupils in response to light and focus. In neuro-ophthalmology, these changes can indicate issues in the brain or nervous system. For example, pupils that are uneven may suggest pressure on the optic nerve or a neurological condition. Fixed or dilated pupils might signal serious problems such as brain injury or stroke. Assessing pupil responses helps doctors understand underlying health issues, guiding diagnosis and treatment.
