Indications

Procedure

  • surgical creation of a small hole in the sclera covered by a thin trap-door in the sclera
  • aqueous humor drains through the trap-door to a small reservoir reservoir between the sclera & conjunctiva to form a small drainage bleb that is usually hidden under the upper eyelid.
  • the trap-door is sutured in a way that prevents aqueous humour from draining too quickly
  • by draining aqueous humour, trabeculectomy reduces pressure on the optic nerve & prevents or slows further damage & further loss of vision in glaucoma
  • control of the eye pressure with a trabeculectomy will not restore vision already lost from glaucoma
  • trabeculectomy often performed under local anaesthesia, though it may also be performed under general anaesthesia
