Conjunctival cysts may be congenital or acquired. A common cause of acquired conjunctival inclusion cysts is the implantation of conjunctival epithelium after surgery or trauma. These cysts often form at the site of muscle reattachment after strabismus surgery. They may disappear spontaneously, but persistent cases often require surgical excision. We report a new technique using cauterization under slit-lamp visualization to treat conjunctival inclusion cysts that can form after strabismus surgery. This procedure is fast, effective, and well tolerated by patients.
Careful and intact removal of conjunctival cyst is important to prevent recurrence. Minor modifications in surgical technique according to the size, site and nature of cyst help in intact removal and prevent recurrence.
During excision of cyst conjunctiva along with tenon’s was held with non-traumatic forceps gently above the cyst, a small incision was given and the blunt tip of scissors introduced between cyst and tenon’s to separate the cyst from the surrounding tissue. Conjunctiva above the cyst was left as such, which helped to hold the cyst firmly during blunt dissection. Care was taken to keep the tip of the corneal scissors away from the cyst. After separating the cyst from all sides, its base was dissected carefully, as the base of the cyst ruptures most commonly during the dissection. Conjunctiva above the cyst was pulled in the opposite direction of the dissection area, so that fibrous attachments at the base of the cyst were stretched and became easily visible which helped in intact cyst removal.
Cysts smaller than 3 mm size and multiple small cysts in lymphatic cyst were removed along with the adjoining sub conjunctival tissue. Cysts with pterygium were excised along with pterygium tissue. Reverse peeling of pterygium was performed in all patients to avoid rupture of cyst, which was particularly located at the head of pterygium. In reverse peeling, body of pterygium was cut near the canthus and reflected back on the cornea, then it was peeled off by holding the pterygium tissue near the limbus.
