A 16-year-old boy presented with a painless swelling of the left upper eyelid for 1 month, with no history of trauma. Examination revealed 2 hard, well-defined whitish projections arising from a fullness in the medial third of the upper eyelid (A). Computed tomography demonstrated a well-defined hyperdense structure with crown–root morphology arising from the left orbital roof, extending into the preseptal space and projecting externally with 2 tooth-like projections on its surface (B). Surgical excision revealed a mature canine tooth (C, D) without teratomatous elements, consistent with an ectopic tooth of the superior orbit.

A patient presented with an unusual case of a nasal subconjunctival Mydriasert insert in the right eye, detected 3 weeks after uneventful cataract surgery. The insert had been placed pre-operatively to achieve mydriasis, and sub-Tenon’s anesthesia was performed in the inferonasal quadrant. At the routine postoperative visit, the patient was asymptomatic and satisfied with the visual outcome but noted a small nasal conjunctival swelling. Slit-lamp examination revealed the Mydriasert insert within the subconjunctival space, which was removed easily under aseptic conditions at the slit lamp. The most likely mechanism was migration of the insert through the sub-Tenon entry site created during anesthesia. This case highlights the importance of confirming removal of the Mydriasert insert before surgery and carefully inspecting the conjunctival fornices thereafter to prevent retention and possible postoperative complications.
