SURGICAL TREATMENT OF ENTROPION CASE IN 15 DOGS

Abstract

Entropion is the inward curving of part or all of the eyelid margin to contact the corneal surface. It is
the most common eyelid anomaly in dogs. Entropion may develop due to primary causes such as
congenital or developmental entropion or secondary causes such as spastic and cicatricial entropion.
Entropion can be lateral, medial, angular or total. It can affect the lower and/or upper eyelid, or both.
Before permanent surgical intervention of entropion, spastic causes must be eliminated.
The aim of this study was to evaluate the outcome of the Hotz–Celsus and Modified Hotz–Celsus
techniques used for the operation of a total of fifteen dogs with lateral canthus and lower eyelid entropion. Eight of the fifteen cases had bilateral lateral canthus entropion, one case had unilateral
lateral canthus entropion, four cases had unilateral lateral lower eyelid entropion, and two cases had
bilateral lateral lower eyelid entropion. Symptoms such as epiphora, photophobia, blepharospasm and
mucoid discharge were observed in all cases. In five cases with superficial keratitis; corneal irritation,
increased corneal opacity, neovascularization, epiphora, photophobia, blapharospasm, conjunctival
hyperemia were detected. Conjunctivitis was seen in eight cases. Among these, conjuctivitis was
bilateral in six cases and unilateral in two cases. Epiphora, photophobia, blepharospasm and mucoid
discharge were detected with conjunctivitis.
Nine dogs diagnosed with lateral canthal entropion were operated using the Modified Hotz-Celsus
technique, and six dogs diagnosed with lower eyelid entropion were operated using the Hotz-Celsus
technique. For post-operative antibacterial therapy, amoxicillin-clavulanic acid (PO at a dose of 12.5
mg/kg) was administered twice a day for five days. Each patient was fitted with a protective
Elizabethan collar. Stitches were removed within 14-16 days after surgery. For the treatment of
entropion-induced superficial keratitis, 0.5% levofloxacin, 0.15% sodium hyaluronate drops and
carbomer gel were applied topically for 21 days after surgery.
No complications were observed in thirteen dogs after eyelid surgery. Revision operations were
required in two cases. In the follow-up examinations performed one year later, it was determined that
the dogs did not have any eye problems. As a result, it was determined that Modified Hotz-Celsus and
Hotz-Celsus methods were successful for the treatment of lateral canthal entropion and lower eyelid
entropion in dogs. In general, no complications related to the operation techniques were encountered.
