Patients with<unk>  typically experience a dull fluctuating aching over the trochlear region developing over a few days. Some may also feel occasional sharp pains punctuating the ache. In patients with migraines,<unk>  may occur simultaneously with headache. Presentation is usually unilateral with palpable swelling over the affected area supranasal to the eye. The trochlear region is extremely tender to touch. Pain is exacerbated by eye movements looking down and inwards, and especially in supraduction (looking up) and looking outwards, which stretches the superior oblique muscle tendon. Notably, there is no restriction of extraocular movements, no diplopia, and often no apparent ocular signs such as proptosis. However, occasionally mild ptosis is found. The absence of generalized signs of orbital involvement is helpful in eliminating other more common causes of periorbital pain.
