CONJUNCTIVAL CYSTIC PTERYGIUM

Conjunctival cysts are thin walled cysts . They usually progress gradually. They are symptomless during early stages but as they increase in size, they can lead on to cosmetic disfiurement, reduced ocular motility, foreign body sensation and dry eye. They can be primary or secondary. Primary cyst are congenital and usually hidden in the fornix and increase in size slowly. The secondary cyst can be implantation cyst following trauma, parasitic cyst, cystic pterygium or degenerative cyst. Treatment is complete excision where care must be given for intact removal to prevent recurrence. In some cases of parasitic cysts, even lateral orbititomies may be needed to remove the cyst completely.
