Tectonic corneal lamellar grafting for surgically-induced necrotizing scleritis after strabismus surgery: Case report & literature review.

PURPOSE: To report the first case of infectious surgically-induced necrotizing scleritis following strabismus surgery which was treated successfully with a tectonic corneal graft.

OBSERVATIONS: We report a case of surgically-induced necrotizing scleritis after strabismus surgery in a 61-year-old gentleman with gout and a subconjunctival abscess. Surgical drainage of the subconjunctival abscess led to a diagnosis of scleral melt which was subsequently treated with a tectonic corneal graft along with aggressive medical management. Over the following eight months, the patient showed no signs of endophthalmitis, graft necrosis, nor graft dehiscence, and serial anterior segment optical coherence tomography imaging demonstrated anatomic stability.

CONCLUSIONS AND

IMPORTANCE

This case offers further insights into a rare but vision-threatening and potentially life-threatening diagnosis. In conjunction with aggressive local and systemic treatment, tectonic lamellar keratoplasty provides good therapeutic and tectonic results for scleral necrosis after strabismus surgery. This case also demonstrates the importance of screening for associated systemic risk factors in any patient with scleritis for appropriate, targeted therapy.
