Abnormal eyelid disease in dogs
Entropion in Dogs
Entropion may be a genetic condition during which some of the eyelids is inverted or folded inward. this will cause an eyelash or hair to irritate and scratch the surface of the attention, resulting in corneal ulceration or perforation. It also can cause dark-colored connective tissue to create up over the wound (pigmentary keratitis). These factors may cause a decrease or loss of vision.
Entropion is fairly common in dogs and is seen during a big variety of breeds, including short-nosed breeds, giant breeds, and sporting breeds. Entropion is nearly always diagnosed around the time a puppy reaches its first birthday.
The condition or disease described during this medical article can affect both dogs and cats. If you'd wish to learn more about how this disease affects cats, please visit this page within the PetMD health library.
Symptoms and kinds
In toy and brachycephalic breeds of dogs, excess tears (epiphora) and/or inner eye inflammation (keratitis) are common signs of entropion. However, in giant breeds, it's more common to ascertain mucus and/or pus discharge from the outer corner of the eyes. In other breeds of dogs, eye tics, discharge of pus, eye inflammation, or maybe rupture of the cornea are the standard signs of entropion.
Causes
Facial shape is that the primary genetic explanation for entropion. In short-nosed, brachycephalic breeds of dogs, there's more tension on the ligaments of the inner eye than would normally be seen. This, alongside the conformation (shape) of their nose and face, can cause both the highest and bottom eyelids rolling inward toward the eyeball. Giant breeds have other problems. they tend to possess excess slack within the ligaments around the outer corners of their eyes. this allows the outer edges of the eyelids to fold inward.
Repeated bouts of eye infections (conjunctivitis) can cause spastic entropion, which may cause functional entropion. this will even be caused by other sorts of eye irritants and is usually the case in breeds that don't normally exhibit entropion. Lastly, inflammation of the chewing muscles or severe weight loss can cause loss of fat and muscle around the orbit, which can be another cause for entropion.
Diagnosis
The diagnosis of entropion is fairly straightforward through examination. Any underlying causes or irritants should be addressed before attempting surgical correction. Breeders should pay close attention to puppies, especially those that are prone and have them checked for entropion if their eyelids don't open by four or five weeks old.
Treatment and Care
In young dogs, secondary problems are addressed first. Ulcerated corneas are often treated with antibiotics or triple antibiotic ointments. If the condition is mild and therefore the corneas aren't ulcerated, artificial tears are often wont to lubricate the eyes; however, surgery is usually required. this is often done by temporarily turning the eyelid inward or outward (everting) through suturing. This surgery is completed in moderate cases, and when an adult dog with no history of the condition exhibits entropion. In severe cases, facial reconstruction is going to be necessary, but this is often generally avoided until the dog has reached adult size.
Living and Management
Entropion requires routine follow-up care, with any medications prescribed by your veterinarian. this might include antibiotics to treat or prevent infection, and eye drops or ointment. within the case of temporary non-surgical solutions, there could also be a requirement to repeat the procedure until the matter has been resolved, or until your dog is sufficiently old for a more permanent solution. If your dog is suffering or is scratching at the affected eye, you'll want to use an Elizabethan collar to stop your dog from scratching at the attention and making it worse.
Prevention
Entropion is typically caused by a genetic predisposition, it cannot be prevented. If your dog is of a breed that's known to be affected with entropion, prompt treatment is your best choice once it's diagnosed.
