(ophthalmologic)Difficulty moving the eye in one or more directions due to impaired function of the rectus muscles.
Frequency: 65-80% of patients
Pain with eye movement
(ophthalmologic)Sharp or aching pain when moving the eyes, especially when looking toward the affected side.
Frequency: 50-65% of patients
Headache
(neurologic)Dull or throbbing headache, often localized around the forehead or eye region.
Frequency: 45-60% of patients
Eyelid drooping
(ophthalmologic)Drooping or sagging of the upper eyelid, which may partially cover the pupil.
Frequency: 40-55% of patients
Eye bulging
(ophthalmologic)Forward displacement of the eye from the orbit, causing the eye to appear more prominent.
