Entropion Repair

Entropion — inward-rolling eyelids that scrape the eye with every blink — is corrected surgically to end chronic pain and protect your pet's vision.

Entropion is a condition in which one or both eyelids roll inward so that the eyelashes and skin rub against the surface of the eye (cornea) with every blink. It is one of the most common eyelid abnormalities in dogs, and it causes persistent pain, tearing, squinting, and corneal damage that can lead to scarring and vision loss if untreated. Some breeds are genetically predisposed, while other animals develop entropion secondary to injury or chronic spasm. Surgical correction at Dog & Cat Hospital Calabasas precisely removes a small strip of skin to rotate the eyelid to its normal position — stopping the irritation and allowing the eye to heal.

Why It's Recommended

Entropion does not resolve on its own, and medical management — lubricating eye drops — only partially alleviates the discomfort without addressing the cause. Chronic corneal irritation from entropion leads to:

  • Corneal ulceration — open sores on the surface of the eye
  • Corneal scarring (pannus) that permanently affects vision
  • Corneal perforation in severe or neglected cases
  • Chronic pain and behavioral changes from constant eye discomfort

Surgery is the definitive treatment and is recommended once the diagnosis is confirmed in a fully mature pet. Puppies may receive temporary sutures (tacking) to protect the eye while the face develops to its adult conformation before permanent repair.

How the Procedure Works

Entropion repair (the Hotz-Celsus technique is the most widely used) is performed under general anesthesia. The steps:

  • The precise width and length of the skin to be removed is carefully measured — this planning step determines the final eyelid position
  • A crescent-shaped strip of skin and subcutaneous tissue is excised from just below (or above) the affected eyelid margin
  • The wound is closed with fine sutures that evert (roll outward) the eyelid edge to its correct position
  • The same technique is applied to the upper or lower lid independently, or both, depending on where the entropion is located

In complex cases or breeds with severe facial skin folding, additional procedures — such as medial canthoplasty to narrow the corner of the eye — may be combined at the same time.

Preparation

Before surgery, the full extent of the entropion is assessed and the cornea is stained with fluorescein dye to reveal any ulcers that need treatment concurrently. Pre-anesthetic bloodwork is run. If a corneal ulcer is present, topical antibiotic eye drops may be started before surgery. The pet should be at adult facial conformation before permanent repair — typically 12 months for smaller breeds and 18–24 months for large and giant breeds whose faces continue to develop longer. Food is withheld the night before the procedure.

Recovery & Aftercare

Entropion repair is a day procedure. Recovery is straightforward:

  • Days 1–10: e-collar worn at all times to prevent rubbing; prescribed antibiotic and anti-inflammatory eye drops administered
  • 10–14 days: suture removal at a recheck visit; the eyelid position and corneal surface are assessed
  • 2–4 weeks: the eye should be open, clear, and comfortable; any corneal scarring from prior irritation lightens over subsequent months

The improvement in comfort is usually obvious within the first few days after suture placement — pets that previously squinted constantly often open their eye fully for the first time in months.

Risks & What to Expect

Entropion repair is highly effective, and the main technical risk is over- or under-correction. Undercorrection (residual inward rolling) may require a second, smaller revision procedure. Overcorrection (ectropion — outward rolling) exposes the conjunctiva and can cause its own irritation. Precise surgical planning minimizes both outcomes. Breeds with extreme skin folding — Shar-Peis, Chow Chows, giant breeds — may require staged procedures or more extensive reconstruction. Infection of the suture line is uncommon. Even after successful repair, corneal scarring from prior entropion is permanent, though it often fades partially over time as the eye remains comfortable.

Frequently Asked Questions

1What breeds commonly get entropion?
Chow Chows, Shar-Peis, Bulldogs, Retrievers (Labrador and Golden), Rottweilers, and St. Bernards are among the most commonly affected dog breeds. Entropion also occurs in Persian and Himalayan cats.
2Can entropion in dogs go away without surgery?
No — structural entropion does not self-correct. Lubricating drops ease discomfort but don't fix the eyelid position, and the cornea continues to be damaged with every blink until surgery corrects the lid.
3How old should my puppy be before getting entropion surgery?
Permanent surgical repair is generally recommended once the pet has reached adult facial conformation — typically around 12 months for most breeds, or 18–24 months for large and giant breeds. Temporary tacking sutures protect the cornea during the waiting period.
4Will my dog need surgery on both eyes for entropion?
Many dogs with entropion are affected in both eyes to varying degrees. Both can be corrected in a single anesthetic episode, which is the most practical approach.
5Is entropion surgery painful for dogs?
Surgery is performed under general anesthesia with local nerve blocks for comfort. Post-operative discomfort is generally mild and well-managed with medications. Most pets seem more comfortable after surgery than before it.
6How much does entropion surgery cost for a dog?
Cost depends on the extent of the correction needed, whether one or both eyes are treated, and any concurrent corneal treatment required. A written estimate is provided at the surgical evaluation.
7What happens if entropion is left untreated?
Untreated entropion causes progressive corneal damage — ulcers, scarring, and in severe cases, perforation of the eye. Chronic pain is also a significant welfare concern. Early correction gives the best chance of preserving clear, comfortable vision.
8Will the corneal scarring from entropion go away after surgery?
Existing corneal scarring is permanent, but it often fades gradually over months as the eye heals in a comfortable, non-irritated environment. Severe scarring affecting vision may require additional ophthalmic evaluation.
