An 84-year-old woman presented with a 3-month history of conjunctival chemosis in the left eye. At the first examination, the chemosis neighbored the lacrimal caruncle and was localized in the inferomedial region of the conjunctiva. During eyelid closure, only the left lacrimal caruncle was exposed. One month later, the chemosis further extended to the inferolateral region. We debulked the lacrimal caruncle to prevent the exposure of the caruncle. One month after the surgery, conjunctival chemosis had resolved completely. At the postoperative 6-month follow-up, the patient showed no recurrence of chemosis.
