Supplementary Material for: Infected inclusion cyst of a conjunctival nevus treated with a mini-incision: A case report.

Introduction Conjunctival cysts are usually asymptomatic but they can cause foreign body sensation and contribute to dry eye disease. The purpose of this case report is to describe the presentation and treatment of an infected inclusion cyst of a conjunctival nevus in a healthy 36-year-old patient. Case Presentation A healthy 36-year-old-man presented to the emergency department for a redness and pain in his left eye for 1 day. Slit lamp examination revealed a conjunctival hyperemia and conjunctival nevus with 4 inclusion cysts, one of which was filled with a purulent material. Fluoresceine staining of the conjunctival epithelium was negative. Α mini-incision of the white cyst was performed using a 30 G needle, followed by a bimanual drainage and topical treatment with tobramycin and moxifloxacin drops every 3 hours for a week. A swab of the purulent drainage was positive for Gram+ flora. One week after the drainage of the cyst, the patient was asymptomatic and on slit lamp examination, the 4 inclusion cysts were filled with a transparent liquid, there was not any vessel dilation and staining with fluorescein was negative. Conclusion Conjunctival inclusion cysts, although considered benign, can become infected and form a conjunctival abscess. A mini-incision on the slit-lamp combined with bimanual drainage and followed by topical antibiotic drops seems to be a safe and effective treatment.
