Peripunctal tumors usually account for as low as 6.3% of all punctal lesions. Peripunctal nevus is benign in nature, but it can cause epiphora by its sheer mass effect or cosmetic blemish. Anterior segment optical coherence tomography has recently been used in various lower punctal pathologies. A 60‑year‑old lady presented with a painless, benign peripunctal nevus and underwent excision biopsy. Anterior segment optical coherence tomography was used for its in vivo assessment and defining features of the lesion. It showed a hyperreflective epithelial thickening and gradient hyporeflective layers with punctal occlusion.

Schwannomas are slow-growing, well-defined, and pseudo-encapsulated arising from the Schwann cells of the peripheral nerves. Usually, schwannomas are presented intracranially. Intraorbital schwannomas' incidence is as low as 1-2% of all orbital tumors. Ab-ducens nerve schwannoma in the orbit originating from the terminal branches which supply to the lateral rectus is extremely rare. A 45-year-old lady presented with painful proptosis of 10 mm with no extraocular muscle movement restriction. She underwent lateral orbitotomy with excision biopsy and was histopathologically diagnosed as schwannoma. On follow-up, she had total recovery of the abducens nerve.
