Osseous Metaplasia of the Eyelid in a Child.

Osteoma cutis is a term applied to bone formation in the dermis or subcutaneous tissue. It is deemed primary when occurring de novo without prior disease or secondary when associated with pre-existing inflammation, neoplasia or trauma. The authors describe a longstanding focal calcified and ossified lesion of the upper eyelid in a healthy 10-year-old girl along with a sterile corneal ulcer. The lesion most likely represented an ossified tarsal cyst or chalazion.

Postrefractive infectious keratitis: prevention, diagnosis, management, and prognosis.

PURPOSE OF REVIEW: Improve outcomes from an elective procedure by preventing a rare but sight-threatening complication. RECENT FINDINGS: Advancement in anti-infective prophylaxis, and therefore shift in the causative organism permits better diagnostic and empiric management. SUMMARY: Infectious keratitis presents in different patterns depending on the refractive procedure. Atypical causative organisms may respond poorly to empiric therapy and impair vision. Therefore, microbial identification is of utmost importance and therapy is adjusted accordingly.
