INTRODUCTION: We describe a technique using an sclerocorneal endograft sewed through the cornea to solve late scleromalacia following exoresection and brachytherapy of a ciliary body melanoma.
METHODS: Vitrectomy ports were placed. A perforating 400-micron trepan keratoplasty of the cornea was performed allowing the prepared donor graft to be inserted and sutured in place. Intravitreal Perfluorocarbon liquid (PFCL) was used to stabilize the pressure throughout and maintain the graft in place. Once sutured in place, the PFCL was removed and 5000cs of silicone oil introduced. An amniotic membrane was placed surrounding the scleromalacia. The cornea was closed with running sutures.
RESULTS: At one month, the anterior segment optical coherence tomography showed successful endograft placement with no aqueous humor leakage nor hypotony. Currently, the conjunctiva is becoming slightly thicker due to light inflammation, and the eye has recovered the whiteness at the scleromalacia.
CONCLUSIONS: This internal graft technique provides advantages when dealing with poorly healing radiated tissue and reduces the risk of post-operative aqueous humor leakage. Surgeons may consider this approach in cases with a high risk of poor healing or complications resulting from lack of tissue.
