Trochleitis is the swelling of structures in the eye
that help control eye movement, specifically the oblique tendon and
surrounding tissues. Trochleitis may be isolated (occur alone or with
migraine) or develop in association with an inflammatory condition, such
as lupus or arthritis. Signs and symptoms include aching and/or
stabbing pain in the inner orbit of the eye (e.g., near the nose and
inner eyebrow). The pain tends to worsen when looking up and down, and
when gentle pressure is applied. Trochleitis
usually affects a single eye, but can involve both eyes. Ultrasound
imaging and noting a rapid improvement with locally injected corticosteroids aids in diagnosis. Treatment may involve
oral or locally injected corticosteroids. Long-term outlook is good with
symptoms resolving within weeks to months in most cases.
