Conjunctival Cysts

Conjunctival cysts form on the conjunctiva of the eye and are of two types – retention cyst and inclusion cysts although they are often grouped into the same diagnosis.


  • Often described by patients as a blister or water filled blister on front of eye
  • Can cause mild discomfort and increased tearing
  • Often asymptomatic


  • Retention cysts usually stem from a blocked duct which allows the build up of secretions from glands within the eye
  • Inclusion cysts are normally linked to a piece of epithelium from the conjunctiva folded over into the conjunctiva beneath it which then fills with serous fluid.


  • Usually none- they can self-resolve
  • Topical lubricant
  • Rarely referral for surgical intervention
