Limbal cyst following blunt trauma in an operated case of congenital cataract: a rare scenario

A 15-year-old male patient with the history of bilateral operated congenital cataract surgery 5 years back now presents with gradual painless diminution of visual acuity in left eye following a blunt trauma with a fist. Ocular examination showed a well-defined slightly bluish-tinged limbal-based conjunctival cyst without any irregularities in the anterior chamber/pupil. Intraocular pressures were 16 mm Hg in the right eye and 10 mm Hg in the left eye; retinal examination showed findings consistent with hypotonic maculopathy. Anterior segment ultrasound biomicroscopy revealed a well-defined limbal cyst with anterior chamber communication. Under local anaesthesia, the cyst was completely excised with the reconstruction of the sclerocorneal defect. At the end of 6 months, the patient is symptom-free with pretraumatic visual acuity.
