Treatment

Medical Care

Excisional biopsy is the treatment of choice. Topical cytotoxic therapy (ie, 5-fluorouracil [5-FU], mitomycin C [MMC]) has been used to treat CIN and to debulk large carcinomas prior to surgical excision.

Surgical Care

  • Surgical excision is best performed under the operating microscope.
  • Removal of a cuff of normal conjunctival tissue surrounding the lesion is prudent, and an episclerectomy at the base of the lesion is also advisable if it is adherent to the sclera in order to remove any superficial cells infiltrating the sclera.
  • Involved corneal tissues may be best removed following treatment with 100% ethanol. The tissues superficial to the Bowman layer are removed easily in a single sheet and sent to the laboratory for analysis. Care should be taken not to incise into the Bowman membrane.
  • Cryotherapy is performed, in a double freeze-thaw manner, to the edges of the uninvolved conjunctiva and Tenon capsule. It also can be applied to the involved limbal area.
  • The exposed sclera occasionally is treated with 100% ethanol to devitalize any remaining tumor cells.
  • All excised tissues are submitted for histopathologic analysis.
  • Reconstruction is performed with direct closure, local flaps, or free conjunctival grafts.
  • Extensive lesions with orbital involvement require exenteration.
  • Radiation therapy may be used as adjunctive therapy in cases of extensive lesions with poorly defined margins and as palliative therapy in cases where the patient cannot tolerate extensive surgery.

Consultations

An oncologist should be consulted if metastatic disease is suspected.
