Trochlear pain: clinical characteristics and treatment outcomes

Abstract

Trochlear pain is frequently overlooked as published data regarding the clinical characteristic and current treatment are limited. The aim of this study is to evaluate this information from our experiences with trochlear pain. Medical records of 43 patients with trochlear pain from HRH Princess Maha Chakri Sirindhorn Medical Center between November 2010 and April 2017 were reviewed. Most patients were female (88%), with a median age of 51 years. Common characteristic symptoms of trochlear pain were acute, episodic, dull or pressure-like, periorbital pain, often radiating to the forehead, and aggravated by eye movements, especially reading. The causes of trochlear pain were idiopathic or primary trochlear headache (n = 33, 77%) and trochleitis (n = 10, 23%). Treatments included oral NSAIDs or dexamethasone injection into the trochlear region. At a median follow-up of 11 months (range 0–64), 67% of the patients reported complete remission using oral medication. Local steroid injection is useful in non-responding patients to oral therapy with an overall remission of 86%. Successful treatment outcome was achieved in most patients. © 2017, Springer-Verlag GmbH Germany, part of Springer Nature.
