Causes of Ectropion
Ectropion can develop for several different reasons.
In many dogs, it is related to their natural facial shape and eyelid structure. This is the most common form and is frequently seen in breeds such as Bloodhounds, Spaniels, and St Bernards, where the lower eyelids may naturally be looser or droop away from the eye.
Other causes can include:
• Scarring or previous injury to the eyelid
• Chronic inflammation affecting the eyelid tissues
• Growths or masses that pull the eyelid out of position
• Conditions affecting the nerves or muscles that control the eyelids
• Occasionally, underlying hormonal conditions such as hypothyroidism
• Previous eyelid surgery, particularly if earlier corrective surgery has altered the eyelid position too much
Identifying the underlying cause is important when deciding on the most appropriate treatment for your pet.
Surgical Management
The aim of surgery for ectropion is to improve the position and support of the eyelid so that it can better protect and lubricate the eye.
The type of surgery recommended will depend on your pet’s individual eyelid shape, the severity of the condition, and whether any other eyelid problems are present at the same time.
Some procedures involve shortening or tightening parts of the eyelid, while others help improve support at the outer corner of the eye. In certain patients, surgery may also address inward rolling of the eyelid (entropion) if both conditions are present together.
Because these procedures alter the position and shape of the eyelids, they may also change your pet’s appearance slightly. This will always be discussed with you fully before surgery so you understand the expected outcome and goals of treatment.
Aftercare
Following surgery, most patients require around two weeks of lead walking using a harness and restricted activity while the surgical site heals. An Elizabethan collar (cone) is usually needed to prevent rubbing or scratching at the eyes.
Pain relief medication will be provided, and some pets may also need eye drops or additional treatments during recovery.
