Roberts-Bistner blepharoplasty for correction of bilateral eyelid agenesis in a cat

Abstract

Eyelid agenesis, also known as palpebral coloboma, is the most frequent congenital abnormality of feline´s eyelid compromising the patient's ocular health. The treatment of choice is blepharoplasty, which can be performed using different surgical techniques, depending on the extent of the coloboma. This paper reports a feline case diagnosed with coloboma in approximately 50% of the temporal and bilateral upper eyelid, which was treated using the Roberts-Bistner technique. Attention to the primary surgical care and delicate manipulation of tissues allowed maximum use of the wholly healed flaps. Trichiasis is  a common complication inherent to traditional coloboma correction techniques and despite this was observed in both eyes a few weeks after surgery, the, reconstructive blepharoplasty provided adequate eyelid function and good cosmesis for the correction of eyelid agenesis in this patient.
