Ceratoplastia com enxerto autógeno lamelar livre de córnea e pediculado de conjuntiva fixados com adesivo de cianoacrilato em cães

The cornea is frequently exposed to traumas, lacerations, perfurations and ulcers, needing in most cases surgical correction.  The conjunctival pedicle grafts are indicated in these cases, giving protection and support for ulcers, but obstructing the visual capacity of the affected eye.  The lamelar grafts are other indications for treatment, mainly when preventing the visual loss. The cianoacrylate adhesive was discovered at the end of the forthies, but started to be used in ophtalmology in the begigning of the sixties.  Due to its properties, as good tissue adhesion, quick dried and polimerization, it has been indicated in the treatment of deep or refractive corneal ulcers, descemetoceles and in punctiform corneal perforations. With the objective to test the cianoacrylate adhesive in the fixation and maintenance of corneolamelar grafts and conjunctival pedicle grafts in corneal ulcer, 10 male and female mongrel dogs from the Central Bioterio of Santa Maria Federal University were used.  After anesthesia protocol and routine eyeball fixation, a trephination was performed, involving 2/3 of the corneal stroma, being 5.5mm in diameter in the left eye and 5mm in the right eyes.  The lamelar corneal grafts from the left eyes were fixed in the recipient cornea of the right eyes, using the adhesive in the margin of the graft.  In the left eyes, a conjunctival pedicle flaps were fixed in the corneal deffects, using the same adhesive in the margins. Daily ophtalmologic control was made during 30 days.  The corneal lamelar grafts were incorporated to the recipient cornea.   The fixation technique was rapid and easily performed, with low cost.  The eyes had 20% opacities with the use of the lamelar corneal graft, and 80% with no vascularization and opacities present in 30 days.  When conjunctival flaps technique was used, it has 100% dehiscence of the cases.
