Autotransplantation of the recurrently prolapsed third eyelid gland in dogs

Recurrence of third eyelid gland prolapse after surgical replacement occurs in 5-10% of cases. Re-operation is not always possible and re-operated cases are not always successful. This video shows an autotransplantation of part of the third eyelid gland into the conjunctival fornix as an alternative means of maintaining the aqueous tear film in patients with recurrence of glandular prolapse after surgical replacement using a pocket technique. Surgeon: Dr. João Alfredo Kleiner DVM, MSc. Vetweb Oftalmologia Veterinária.

  6. 6. OBJECTIVES • Evaluation of the clinical effects of autotransplantation of part of the third eyelid gland into the conjunctival fornix • Alternative means of maintaining the harmony of the preocular tear film • Gland produces 30 to 50% of the aqueous part of the precorneal tear film.
