Purpose: Conjunctival retention cysts may recur if not completely removed.However, the cyst wall often ruptures during surgical excision, making complete removal difficult.In order to ensure complete cyst excision, we used a method of staining the inner cyst wall using trypan blue augmented by Methyl cellulose.Observation: Interventional study.

Staining was performed by injecting trypan blue using an insulin needle.Then the needle was kept in place and methyl cellulose was injected to make the cyst content viscous to avoid its read more collapse after removing the needle.By using this technique, it was possible to excise the lesion as a whole.Three patients were included (unilateral).

Two patients had cysts that were secondary to trachoma and were followed for up to 2 years without recurrence.A third patient had a conjunctival cyst following strabismus surgery was not successfully removed.Conclusion: This method is simple and effective for complete excision of conjunctival retention cysts exception for cysts post strabismus surgery.Keywords: Conjunctival cyst, Trypan blue, jilungin dreaming tea Ophthalmic viscosurgical devices, Methyl cellulose.
