SYMPTOMS Typically asymptomatic but could experience diplopia
SIGNS A smooth, painless mass that is typically superior temporal. If deeper in the orbit, it can cause a ptosis, EOM restriction, strabismus, and proptosis
WORK-UP Pupils, EOMs, Cover test, Ptosis evaluation, Exophthalmometry, Full eye exam
TREATMENT No treatment typically needed especially if patient is asymptomatic and/or dermoid is stable

Once the dermoid is treated by an oculoplastic specialist/pediatric ophthalmologist and the eye is stable, the patient should be seen back in 6-12 months
ADDITIONAL LAB | TESTS Typically none but a CT or MRI of the orbit may be needed for dermoids that are deeper in the orbit
ETIOLOGY Congenital choristoma of the orbit
