Abstract
Purpose
To report a new modified method using a mixture of sodium hyaluronate and indocyanine green solution to facilitate the complete removal of a large conjunctival cyst.
Case summary
Two patients with a large conjunctival cyst on the bulbar conjunctiva were treated. In order to achieve complete removal, a mixture of 1% sodium hyaluonate and indocyanine green solution was injected through a 27-G needle into the cyst. The procedure provided excellent visualization of the cyst boundaries while maintaining cyst integrity allowing for an easy and complete resection. Apocrine hidrocystoma and a simple retention cyst were confirmed on histopathologic examination, respectively.
