Relating to the conjunctiva.

conjunctival

pertaining to or emanating from conjunctiva.

congenital conjunctival membrane
partial or complete obstruction of the lacrimal puncta occurs when a conjunctival membrane or flap is present over the opening.
conjunctival flap
surgical movement and fixation of conjunctiva, either bulbar or palpebral, to cover defects in conjunctiva or, more commonly, to cover lacerations or nonhealing, progressive or deep ulcerations of the cornea especially those with desmetoceles. The flaps serve to protect the corneal lesion from eyelid trauma and encourage migration and proliferation of fibroblasts and blood vessels into the area. There are many techniques; some utilize the nictitating membrane.
conjunctival grafts
defects of conjunctiva may be grafted with conjunctiva obtained from elsewhere in the same eye or the opposite eye. Buccal mucosa has also been used for this purpose.
conjunctival granuloma
see nodular fasciitis.
conjunctival sac
the tear-filled space, lined by conjunctiva, between the eyelids and the eyeball.
conjunctival squamous metaplasia
cancer eye. See ocular squamous cell carcinoma.

Fibrin glue has been used as an alternative to sutures for securing the conjunctival grafts.
Recurrence rates following bare sclera resection range from 24% to 89%, 4-5 following bare sclera resection with mitomycin application between 0% and 38%, (3-6,7) and following pterygium resection with conjunctival graft placement between 2% and 39%.
The conjunctival graft was then placed on the scleral bed, with epithelial side up without losing the limbal orientation [figure 8] and the whole graft was compressed gently into position with lens spatula for 5 to 6 minutes to counter any small hemorrhage or fluid accumulation beneath the graft [figure 9] then after stabilization [figure 10] antibiotic-steroid ointment was inserted into the conjunctival sac and the eye was bandaged for 24 hours.
Since then, a considerable number of surgical techniques have been described for its management: simple resection or bare sclera technique, (3,4) avulsion, (5) removal and primary closure, (3,6,7) pterygium head transplant, (8-10) concomitant beta irradiation (13), conjunctival autograft (15,19), limbal conjunctival autograft 15-18, and the use of amniotic membrane with and without conjunctival grafts 20 .
Accordingly, inclusion of limbal epithelium in the conjunctival graft for pterygium surgery would achieve better anatomic and functional reconstruction after pterygium removal and, by restoring barrier function of the limbus, could reduce recurrence.
