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
|
|
Refer to an oculoplastic specialist or pediatric ophthalmologist for surgical removal of the dermoid if the patient is experiencing proptosis and/or diplopia, if the dermoid is growing in size, or if patients wants the dermoid removed for cosmetic reasons
|
|
FOLLOW-UP

See patient back in 12 months in order to monitor dermoid
|
|
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

|
DIFFERENTIAL DX
