Trigeminal neuralgia associated with ophthalmic surgery: a c
Trigeminal neuralgia is a rare cause of postoperative pain after ophthalmic surgery and has only been described twice in the international literature: one case of pain after vitrectomy with a crystalline lens extraction and another case of an unspecified surgery type.

Published in the Journal of Medical Cases, the authors report three cases of ophthalmic surgery-induced trigeminal neuralgia.

Trigeminal neuralgia was diagnosed in three patients after ophthalmic surgery. Patient 1 was a 63-year-old man with an epiretinal membrane and cataract in his left eye. Phacovitrectomy was performed.

Patient 2 was a 38-year-old man with a perforating wound in his right eye. Primary closure of the cornea with removal of the necrotic iris was performed.

Patient 3 was a 52-year-old Caucasian man referred 15 days after suffering blunt trauma to his right eye. Vitrectomy was performed to remove the crystalline lens, which was luxated to the vitreous.

On postoperative days, these three patients were admitted to an emergency ward due to sudden, shock-like, one-sided facial pain activated by numerous stimuli.

After consultation with specialists from the anesthesia and neurology departments, a diagnosis of trigeminal neuralgia was made. This diagnosis was based on the presence of four of the nine clinical criteria described by the International Headache Society, which were met in these three cases.
