A noninflamed, translucent subconjunctival mass may develop if conjunctival epithelium is buried during muscle reattachment or incision closure (Fig 14-5). Occasionally, the cyst resolves spontaneously. Topical steroids may be helpful; persistent cases may require surgical excision. In some cases, the cyst is incorporated into the muscle tendon, so careful exploration is mandatory to identify this complication.
