Surgical excision |
Alcohol epitheliectomy for the corneal component and partial lamellar scleroconjunctivectomy with 3 to 4mm margins for the conjunctival component. Frozen sections may be used to ensure tumour‐free margins. Modified enucleation involves removing the affected conjunctiva with a 4mm margin together with the eyeball. Exenteration involves complete removal of orbital tissue including the periosteum of the bony walls. The eyelids may or may not be spared. |
