Tarsoconjunctival flap for scleromalacia related to treatments for conjunctival melanoma

To describe the use of a tarsoconjunctival pedicle flap for the repair of scleral melt secondary to treatment of conjunctival melanoma.

A 67-year-old woman developed progressive scleromalacia after multiple treatments for an American Joint Committee on Cancer cT2d category conjunctival melanoma. Prior to referral, she underwent synchronous topical chemotherapy (interferon, 5-fluorouracil, mitomycin). Then, incomplete tumor regression led to excision with adjuvant cryotherapy. Lastly, systemic metastasis treated with systemic immunotherapy provided durable remission. However, her multiple treatments (e.g., topical chemotherapy, resection, cryotherapy) were associated with progressive nasal bulbar scleromalacia treated by conjunctival advancement and amniotic membrane grafts. Sclera reinforcement was achieved after a tarsoconjunctival flap was affixed to the eye to cover, and thus vascularize the scleral defect. The tarsoconjunctival flap provided 5 years of tectonic support.

Tarsoconjunctival pedicle flaps can provide scleral integrity for a patient with progressive scleral melting.
