Cherry Eye, Ectropion, and Entropion in Dogs: A Visual Guide

Cherry Eye, Ectropion, and Entropion in Dogs: A Visual Guide

If you notice a red, fleshy lump in the corner of your dog's eye, or if their eyelids seem to roll inward or droop heavily, they may be suffering from cherry eye, entropion, or ectropion. These common eyelid abnormalities alter how the eye functions and can lead to pain, infections, or vision damage if left untreated. Identifying these signs early allows you to seek veterinary care before serious complications like corneal ulcers develop.

• ** is an outward sagging of the eyelid, exposing the sensitive conjunctiva to debris and dryness.
• All three conditions typically require veterinary diagnosis and often surgical correction to prevent permanent eye damage.

Why it matters

The canine eye is a delicate, highly specialized organ. Unlike humans, dogs possess a third eyelid (nictitating membrane) located in the inner corner of the eye. This membrane provides an extra layer of protection and houses a crucial tear-producing gland. The eyelids themselves must fit perfectly against the eyeball to distribute tears evenly and sweep away debris.

When the structural integrity of these eyelids is compromised, the eye is exposed to friction, dryness, and environmental hazards. Conditions like cherry-eye (prolapse of the third eyelid gland), entropion (inward-rolling eyelids), and ectropion (outward-sagging eyelids) are not merely cosmetic issues. They disrupt the eye's natural defense mechanisms, leading to chronic irritation, painful corneal ulcers, corneal scarring, and potentially permanent vision loss. Recognizing these conditions early is vital to preserving your dog's sight and comfort.

What good looks like

A healthy canine eye should be bright, clear, and free of abnormal discharge. The sclera (the white part of the eye) should be clean and white, not bloodshot, red, or yellow. The conjunctiva (the moist tissue lining the eyelids) should be a soft, healthy pink.

A healthy dog eye features tight, well-aligned eyelids, a clear cornea, and no abnormal redness or discharge.

The eyelids themselves should rest snugly against the surface of the eyeball. They should neither roll inward to rub against the cornea nor sag outward to expose the sensitive inner tissues. There should be no squinting, pawing, or excessive tearing. The third eyelid should remain tucked away, barely visible in the inner corner of the eye unless the dog is very sleepy or relaxed.

Step-by-step

Inspecting your dog's eyes at home should be a gentle, stress-free process. Follow these steps to safely check your dog's eyes for signs of cherry eye, ectropion, or entropion:

1. Find a well-lit space: Choose a quiet room with plenty of natural light, or use a bright overhead light. Avoid shining a flashlight directly into your dog's eyes.
2. Secure your dog gently: Have your dog sit or lie down comfortably. If they are wiggly, ask a family member to gently hold their body and support their chin.
3. Observe from a distance first: Look at your dog's face head-on. Check for symmetry. Are both eyes open fully? Is there squinting, blinking, or tear staining on one side?
4. Inspect the eyelids: Gently use your thumb to slide the skin above the upper eyelid upward, and your index finger to slide the skin below the lower eyelid downward. Look closely at the edges of the lids. Do they roll inward toward the eyeball, or do they sag and droop away from it?
5. Check the inner corner: Look at the inner corner of the eye near the nose. Is there a pink or red mass protruding? Is the third eyelid visible and inflamed?
6. Look for discharge: Note the color and consistency of any discharge. Clear tears are common with mild irritation, while yellow or green discharge indicates infection.

Signs something's wrong

Each of the three major eyelid conditions has distinct visual markers and symptoms. Understanding what to look for will help you identify which issue your dog might be experiencing.

Cherry Eye (Prolapsed Gland of the Third Eyelid)

Cherry eye occurs when the fibrous attachment holding the tear gland of the third eyelid in place weakens, causing the gland to pop out (prolapse) of its normal position.

Cherry eye appears as a smooth, pink or red fleshy mass protruding from the inner corner of the eye.

• Visual appearance: A smooth, round, pink or bright red fleshy mass protruding from the inner corner of the eye. It closely resembles a small cherry.
• Other symptoms: Mild squinting, watery eyes, or pawing at the face. The gland can become dry, inflamed, and irritated the longer it remains exposed.
• Commonly affected breeds: French Bulldogs, [English Bulldogs](</p/breeds/englishbulldog_dog>), [Cocker Spaniels](</p/breeds/englishcockerspaniel_dog>), Beagles, Lhasa Apsos, and Shih Tzus.

Entropion (Inward-Rolling Eyelids)

Entropion is a painful condition where the eyelid rolls inward, causing the hair and eyelashes on the outer surface of the lid to rub directly against the sensitive cornea.

• Visual appearance: The edge of the eyelid is not visible because it is rolled inward. The eye often looks smaller because the dog is constantly squinting.
• Other symptoms: Excessive tearing (epiphora), squinting (blepharospasm), holding the eye shut, rubbing the face against carpet or furniture, and a cloudy or bluish appearance to the cornea (indicating a corneal ulcer).
• Commonly affected breeds: Chow Chows, Shar-Peis, Rottweilers, Great Danes, Bulldogs, and Labrador Retrievers.

Ectropion (Outward-Sagging Eyelids)

Ectropion is the opposite of entropion. The lower eyelid sags or rolls outward, exposing the delicate conjunctival tissue that lines the inside of the lid.

Ectropion causes the lower eyelid to sag outward, exposing the sensitive inner conjunctiva to dust and debris.

• Visual appearance: A droopy lower eyelid that sags away from the eyeball, often forming a "V" or "U" shape. The red, moist inner lining of the eyelid is clearly visible.
• Other symptoms: Chronic redness and inflammation of the conjunctiva (conjunctivitis), brown tear staining on the face, and accumulation of dust, dirt, or mucus in the pocket of the droopy lid.
• Commonly affected breeds: Bloodhounds, Basset Hounds, Great Danes, Saint Bernards, and Mastiffs.

When to call your vet

While some eye issues may seem mild, they can escalate rapidly. The cornea is highly sensitive and can scar or perforate quickly if damaged. You should schedule a veterinary appointment within 24 to 48 hours if you suspect your dog has cherry eye, ectropion, or entropion.

During the visit, your vet will perform a thorough ophthalmic exam. They will likely use a fluorescein stain test (a green dye) to check for corneal ulcers caused by rubbing eyelashes or exposure. They may also perform a Schirmer tear test to measure your dog's tear production.

Treatment for these conditions almost always involves surgery. For cherry eye, the gland is typically tucked back into place and sutured (the pocket technique) rather than removed, as removing the gland can lead to chronic dry eye (keratoconjunctivitis sicca). For entropion and ectropion, surgical blepharoplasty is performed to reshape the eyelids so they fit snugly and comfortably against the eye.

Common mistakes

• Waiting for the condition to "fix itself": Eyelid structural issues rarely resolve on their own. Delaying treatment increases the risk of chronic pain, corneal scarring, and permanent vision loss.
• Using human eye drops: Never administer over-the-counter human eye drops (like Visine or redness-relief drops) to your dog. These can cause severe irritation or mask symptoms of a serious underlying infection.
• Attempting to manually "pop" a cherry eye back in: Trying to push a prolapsed gland back into place at home can cause severe pain, introduce bacteria, and damage the delicate tissues of the eye. This must only be handled by a veterinary professional.
• Ignoring mild squinting: Squinting is the primary sign of eye pain in dogs. Even if you cannot see an obvious physical change, persistent squinting warrants a vet visit.

When to call your vet

• Signs are getting worse over hours, not better

• Pain, persistent vomiting/diarrhea, or neurological signs

• Waiting because the animal 'still looks okay' while prey species hide pain

• Changing five variables at once so you cannot tell what helped

• Copying drug doses from social media

• Skipping species-appropriate husbandry while buying more gadgets
