Plain English summary of protocol
Background and study aims
Hemangioma is a benign tumor that is found to grow within the orbit. Most commonly located behind the eye globe, it can push the eye forward causing eye-bulging doctors call proptosis.
The tumor can be removed through surgery entering via the lower eyelid (transconjunctival orbitotomy) using cryotherapy. Cryotherapy uses imaging guidance, a needle-like applicator called a cryoprobe, and liquid nitrogen or argon gas to create intense cold to freeze and destroy diseased tissue, including cancer cells.
The aim of this study is to evaluate the safety and efficacy of cryo-assisted transconjunctival orbitotomy for the extraction of intraconal cavernous hemangiomas.
Who can participate?
Patients with intraconal cavernous hemangiomas
What does the study involve?
The transconjunctival approach will be used for cryo-assisted lesion extraction. Cases will be followed for six months after the surgery.
What are the possible benefits and risks of participating?
Benefits: excision of the orbital tumors, avoid compression of the optic nerve and avoid exposure keratitis
Risks: trauma to the optic nerve, trauma to the globe, rupture of the mass and inability to remove the tumor
Where is the study run from?
Mansoura ophthalmic center (Egypt)
When is the study starting and how long is it expected to run for?
April 2017 to September 2018

| Intervention type | Procedure/Surgery |
| Primary outcome measure | The success of the operation and complications measured using direct interview of patients after six months |
| Secondary outcome measures | None |
