To report a case of sclerocorneal cyst found in a 4-year-old female following strabismus surgery treated with cyst wall excision and scleral graft.

A 4-year-old female with a history of strabismus surgery performed 1.5 year prior presented with a whitish lesion in cornea and sclera which developed 1 month ago. Slit-lamp examination revealed a 4.2 × 3.5 mm-sized cyst at the superotemporal part of the cornea, extending into the sclera at 3-o'clock. Cyst fluid, precipitate aspiration, and cyst wall excision were performed. Scleral patch graft was used to cover the scleral defects after excision. Upon histopathological examination, the cyst wall was lined with nonkeratinized stratified squamous epithelium and numerous degenerated epithelial cells were present in the cyst aspirate.

Sclerocorneal cyst can rarely develop following trauma or surgery. In this report, the sclerocorneal cyst, possibly induced by previous strabismus surgery, was treated successfully without recurrence using cyst wall resection.
