Abstract
Soontornvipart K., N. Tuntivanich, H. Kecova, P. Rau‰er:Conjunctival Pedicle Graft in Dogs and Cats: A Retrospective Study of 88 Cases. Acta Vet. Brno 2003, 72: 63-69. Seventy-eight dogs and ten cats with corneal lesions, including deep corneal stromal ulcers (n = 32), keratomalacia and recurrent erosions (n = 25), descemetocoeles (n = 18), staphylomas and perforating corneal defects (n = 5) and feline corneal sequestrations (n = 8) were treated with 3 types of conjunctival pedicle grafts. Breed, age, sex of the patients, size and depth of corneal lesions, suture material used, surgical technique and postoperative application of antibiotics were evaluated to determine their influence on the success rate of conjunctival pedicle graft. The success rate of the therapy was high (93.18%) and depended chiefly on the surgical technique employed.
Highlights
Seventy-eight dogs and ten cats with corneal lesions, including deep corneal stromal ulcers (n = 32), keratomalacia and recurrent erosions (n = 25), descemetocoeles (n = 18), staphylomas and perforating corneal defects (n = 5) and feline corneal sequestrations (n = 8) were treated with 3 types of conjunctival pedicle grafts
(5), Cocker Spaniel (5), Pug (4), Great Dane (2), crossbreed dogs (18), other breeds (8)) and 10 cats (Persian cats (4) and crossbreed cats (6)) with corneal lesions managed with conjunctival pedicle grafts at the Department of Surgery and Orthopaedics of Small Animal Clinic at University of Veterinary and Pharmaceutical Sciences, Brno, Czech Republic and at the Ophthalmology Clinic, Department of surgery at Chulalongkorn University, Bangkok, Thailand in period 2001-2002 were evaluated
We evaluated the influence of type and size of the lesion on the success rate of conjunctival pedicle graft (Table 1)
Summary
Seventy-eight dogs and ten cats with corneal lesions, including deep corneal stromal ulcers (n = 32), keratomalacia and recurrent erosions (n = 25), descemetocoeles (n = 18), staphylomas and perforating corneal defects (n = 5) and feline corneal sequestrations (n = 8) were treated with 3 types of conjunctival pedicle grafts. Conjunctival grafts are performed both in dogs and cats and can originate from either the bulbar or palpebral conjunctiva These are used to strengthen the weakened corneal stroma, provide fibroblasts, blood vessels, and epithelial cells, which repair defects and offer antimicrobial and antiprotease/anticollagenase activities (Gelatt and Gelatt 1995). Conjunctival grafts have been described in a variety of patterns, the rotational bulbar pedicle graft being the optimal for small animal cornea (Wilkie and Whittaker 1997; Wanichanon et al 1996). Assessment of corneal health and pupil dilation is performed with a pedicle graft, and topical drug penetration is not inhibited (Tuntivanich et al 2001)
