Conjunctival grafting with or without corneal scarification for management of deep corneal ulcers in dogs

The study was done on 13 clinical cases to evaluate different surgical techniques for management of deep corneal ulceration in dogs. The animals were operated under general anaesthesia using diazepam 0.5 mg/kg b.wt and ketamine 5 mg/kg b.wt combination and maintained on isoflurane inhalation anaesthesia. The animals were divided in two groups, in group I (n=8) conjunctival grafting technique was used and in group II (n=5) conjunctival grafting along with corneal scarification was done. The animals were reviewed for 15 days to evaluate surgical outcome and postoperative complications. Success rate was determined by recording the healed cornea using different techniques. Postoperative complication included breakage of the graft, scar formation on ulcer site and varying degrees of corneal opacity in animals of both groups. On the whole good success rate of 87.5% and 80% was observed in group I and II, respectively.
