    Author: Barman M, Finger PT, Milman T.
    Journal: Ophthalmology; 2012 Dec; 119(12):2631-6. PubMed ID: 22858126.
    Abstract:
    OBJECTIVE: To evaluate the outcome of scleral patch grafts in a series of patients undergoing management for uveal and ocular surface tumors. DESIGN: Case series. PARTICIPANTS: Ten patients underwent scleral patch grafting. Five patients had uveal melanoma with extrascleral extension, 2 patients had scleromalacia secondary to plaque radiotherapy for uveal melanoma, 2 patients had suspicious uveoscleral nevi, and 1 patient had invasive conjunctival squamous cell carcinoma with scleral necrosis. METHODS: Retrospective, interventional, noncomparative chart review of patients undergoing treatment for ocular tumors followed by scleral grafts in a tertiary eye care center in the United States between September 2003 and January 2011. Sclera was reconstructed with allogenic scleral grafts. Clinical observations were performed after grafting. MAIN OUTCOME MEASURES: Structural integrity, appearance, and stability of the grafts. RESULTS: Ten patients were reviewed. All melanoma cases received plaque radiotherapy with palladium 103. The cases with nevi and squamous cell carcinoma underwent local resection with cryotherapy as primary treatment. In 8 cases, scleral grafting was performed as part of the initial surgery. In all of these cases, satisfactory anatomic and functional outcomes were achieved. In 2 cases with scleromalacia secondary to radiotherapy for uveal melanoma, grafts were placed several years after the initial treatment. In these 2 cases, one showed signs of graft retraction, whereas another showed graft thinning. No patients experienced graft infection, rejection, or tumor recurrence. CONCLUSIONS: In this series, scleral grafts were well accepted when placed as part of the primary tumor management despite synchronous radiotherapy, scleral resection, or cryotherapy. Grafting was less successful when performed as a late procedure for radiation-induced scleromalacia.
