結膜下睫毛の27ゲージ針による除去：5例における新規低侵襲手技

Subconjunctival migration of eyelashes is an extremely rare phenomenon, and most reported cases are asymptomatic and managed conservatively. In this report, we describe five cases in which subconjunctival eyelashes were successfully and safely removed using a 27-gauge needle. Subconjunctival cilia were identified in five eyes of five female patients aged 42, 52, 53, 78, and 89 years. Under topical anesthesia with benoxinate hydrochloride and slit-lamp observation, a 27-gauge needle was used to puncture the conjunctiva beneath the eyelash, gently guiding its central portion toward the conjunctival surface, after which the eyelash was extracted using fine forceps. In all cases, the procedure was completed within one minute and was associated with minimal intraoperative and postoperative hemorrhage. To our knowledge, this is the first report demonstrating that subconjunctival eyelashes can be rapidly and effectively removed using a 27-gauge needle. This minimally invasive and simple technique can be performed in an outpatient setting without the need for an operating room and may represent a practical and effective option for future clinical management.
