Keywords:cow calf, eye dermoid, lidocaine, surgery, xylazine
A white colored 1-month-old Thari breed cattle calf was brought in the Veterinary Surgery Clinic of Sindh Agriculture University Tandojam for surgery (Surgical manipulation), because of dermoid tissue development on both the eyes by birth. The physical examination of eye showed a dermoid tissue development on both eyes. Dermoid tissue of approximately 1cm size was formed on lower part of eye lid in cornea, causing irritation of eye ball and mild signs of pain on direct palpation. The calf was sedated with 20% Xylazine HCl @ 0.05 mg/kg body weight intravenously. The animal was placed in right lateral position for surgical intervention on a table. Local anesthetic 2% Lidocaine HCl @ 4ml per side was injected locally at site of incision and manipulation. The surgical site was washed with disinfectant and, hairs around eye were removed. Dermoid tissue on lower eye lid was grasped with curved artery forceps and was excised gently by superficial keratectomy procedure. There was no bleeding and then wound was closed with Safil 5/0 (Polyglycolic acid) absorbable suture. It is reported that eye dermoid is genetically transmitted diseases in animals. In conclusion corneal dermoid surgery can be performed using Xylazine and lidocaine by superficial keratectomy procedure.
