A New Simple Technique for Removal of Subconjunctival Cyst under the Slit Lamp Microscope

Purpose: We present a new simple technique to remove subconjunctival cyst under the slit lamp microscope. Case summary: A cotton swab was used to verify whether or not the cyst was freely movable under the conjunctiva. After topical anesthesia, we incised the conjunctiva near the cyst using a 30-gauge needle and extracted the cyst through the wound using forceps under the slit lamp microscope. Four cases of subconjunctival cyst were successfully removed with our new technique. During the average five month (2-10 month) follow-up period, there was no recurrence or procedure- related complications. Conclusions: Some subconjunctival cysts such as an epithelial inclusion cyst which is freely movable without attachment to surrounding tissues can be easily removed with a 30-gauge needle and forceps under the slit lamp microscope. This could be considered as the primary procedure instead of simple aspiration. J Korean Ophthalmol Soc 2011;52(12):1531-1536
