Lip Commissure to Eyelid Transposition Flap to Correct Eyelid Agenesis in Cats in a Shelter Setting - a Case Series.

Five cats were diagnosed with eyelid agenesis in a 6-month period at the Miami-Dade Animal Services, and a total of 9 blepharoplasties were performed using the lip commissure to eyelid transposition flap (LCET) technique. Eyelid agenesis affected 50%-80% of the superiolateral lid in all cats. Postoperatively, partial necrosis of the flap was observed in 4 and partial dehiscence was observed in 1 of the corrected eyelids, occurring where the buccal mucosa was sutured to the conjunctival mucosa. No cats with partial necrosis of the flap were known to have developed trichiasis due to scar tissue formed at the necrotic site. The single case in which dehiscence occurred developed slight trichiasis that may warrant further intervention to ensure permanent hair ablation. Eyelids were cosmetically acceptable and functional at final examination. Patients showed no evidence of initial discomfort at the surgical sites, nor discomfort or progression of corneal disease during the follow-up time. This case series documents a suitable technique to treat cat eyelid agenesis when referral to a specialist is not an option due to lack of resources, such as in shelters or low-cost veterinary clinics. The surgical technique, outcome and complications presented in this case series are evaluated, and discussed.
