OBJECTIVE
To describe a case of inflammatory Terrien's marginal degeneration (TMD) in a young Chinese girl complicated by a corneoscleral cyst who ultimately underwent surgical treatment with cyst excision, corneal patch graft and amniotic membrane graft.
METHODS
Case report.
RESULTS
A 12-year-old Chinese female presented initially with redness and discharge from her right eye with bilateral superior corneal thinning. The patient was diagnosed with TMD. She subsequently developed a corneoscleral cyst 2 years later which doubled in size within 1 year. The patient underwent a cyst excision with lamellar corneal patch graft and amniotic membrane grafting. Histopathological examination of the cyst wall showed a lining of squamous epithelium, consistent with a corneoscleral cyst.
CONCLUSIONS
This is an interesting case highlighting the rare complication of corneoscleral cyst in a young patient with inflammatory TMD. Excision of the cyst with a corneal patch graft and amniotic membrane grafting without any chemical cautery is effective in preventing recurrence.
