A retrospective review of the medical records was performed on patients with THS between March 2016 and January 2020. A total of eleven patients fulfilling the International Classification of
Headache Disorders (ICHD-3 beta) diagnostic criteria for THS were included in this study.
RESULTS: The average age of the patients with THS was 57.18 ± 15.32 years and the mean duration of recovery was 26.91 ± 24.35 days. All eleven patients had orbital or periorbital
pain as the first symptom followed by
diplopia. Ptosis was found in five patients (45.45 %) in the involved eye. Sixth cranial nerve (CN)
palsy was most common (eight cases, 72.73 %), followed by third and fourth CN
palsy (five cases, 45.45 %, respectively),
optic neuritis (two cases, 18.18 %), and trigeminal nerve and facial nerve
palsy (one case, 9.09 %, respectively). One patient with
optic neuritis failed to recover visual acuity and the other ten patients completely recovered their ocular motor limitation. All patients were initially treated with
steroids. One patient relapsed after five weeks and one patient had a history of THS five years earlier.
CONCLUSIONS: THS responded well to
steroid treatment, but if it was accompanied by
optic neuritis as optic nerve involvement, we suggest follow-up with high dose
steroid treatment especially was important.
