Tolosa-Hunt syndrome

Tolosa-Hunt syndrome (THS) is a rare condition that causes painful inflammation behind or around the eye socket (the bony cavity that holds the eye). This inflammation affects a specific area called the cavernous sinus or the superior orbital fissure — narrow passages through which important nerves and blood vessels travel to and from the eye. When these nerves become inflamed, they can no longer work properly, leading to the hallmark symptoms of the disease. The most recognizable symptoms are severe, stabbing or boring pain around one eye, combined with double vision or drooping of the eyelid. These happen because the nerves that control eye movement and the eyelid become compressed or irritated by the inflamed tissue. Symptoms usually affect only one side of the face. The condition can come and go, with episodes lasting days to weeks if untreated. The good news is that Tolosa-Hunt syndrome typically responds very well to corticosteroid medications, such as prednisone. Most people experience dramatic pain relief within 24 to 72 hours of starting treatment. However, relapses can occur, and long-term monitoring is important. Because THS is rare and its symptoms overlap with other serious conditions, getting the right diagnosis can take time. It is sometimes also called painful ophthalmoplegia, referring to the combination of eye pain and paralysis of eye muscles.
