Collie Eye Anomaly (CEA) is a genetic mutation affecting many breeds that causes developmental defects in the eye that can lead to vision deficits or blindness. This defect can be diagnosed by a veterinary ophthalmologist between 6 and 8 weeks of age by visualizing spots of choroidal hypoplasia or a colobomas . It can be associated with microphthalmia or enophthalmia. It can lead to retinal detachment and blindness. Although laser repair of partial retinal detachments can be attempted if detected in early stages, there is generally no treatment for CEA. Vision varies depending on the extent of the lesions and some dogs will become blind. Prevention requires not breeding animals that carry the mutation and this can be achieved through genetic testing of breeding dogs.

Color dilution alopecia is an autosomal recessive genetic disorder that affects dogs with dilute-colored coats causing hair loss. Some dogs will also be affected by secondary bacterial infections so topical management and pruritus treatments may be needed to improve the dog's comfort. Affected dogs and their relatives should not be bred.

The complete blood count (CBC) assesses different parameters of the cells in the blood including total number, appearance, size, and shape. Red blood cells, white blood cells, and platelets comprise the cellular component of the blood.

Conjunctivitis means inflammation of the conjunctiva. If you see excessive tearing from one or both eyes, abnormal discharge, and reddened conjunctival membranes, your cat may have conjunctivitis. The most common causes of conjunctivitis include infectious diseases and non-infectious conditions, including allergies, injuries, hereditary conditions, and tumors. The approach to non-specific conjunctivitis is to use eye medications containing a combination of broad-spectrum antibiotics to control the bacterial infection and anti-inflammatory drugs to reduce the inflammation. The prognosis depends on the specific diagnosis. It can be a recurring condition in some cats.

Constipation is defined as an abnormal accumulation of feces in the colon resulting in difficult bowel movements. Constipation is a condition seen most commonly in mature, middle-aged cats and can be caused by hairballs, ingestion of foreign bodies, pelvic injuries, or obesity and/or lack of exercise. Megacolon is the most common cause of constipation in cats. In most cases, a diagnosis of constipation can be made on the basis of the cat's clinical signs and medical history. Treatment varies depending on the cause of constipation. The long-term outlook varies according to the cause of the constipation; however, most cats can be adequately managed without surgery and resume normal, healthy lives.

Constipation is infrequent or difficult passage of stool or feces and is typically a temporary condition. Though there are many causes of constipation in dogs, most cases are caused by ingestion of irritating or indigestible substances. Constipation is usually diagnosed through a physical examination and medical history. A rectal exam to rule out rectal strictures, tumors, foreign bodies, or other abnormalities may be done. Abdominal radiographs, blood tests, and urinalysis are valuable for a full diagnosis and development of a treatment plan. Biopsies may also be recommended if a rectal mass or stricture is suspected. Most cases of constipation are relatively easy to treat through the use of manual removal, enemas, and medications. The prognosis for constipation is determined by the exact cause.

Corneal dystrophy is a term used to describe several conditions that occur in dogs and cause the corneas to become opaque. There are three major categories of corneal dystrophy: epithelial, stromal, and endothelial. Each is named by the anatomic location of the abnormal tissue and opacity.

This handout outlines corneal ulcers in cats, a painful eye condition often resulting from trauma. Other causes, clinical signs, diagnostic testing, and treatment options are also explained.
-
The cornea is the transparent, shiny membrane that makes up the front of the eyeball. With a corneal ulcer, fluid is absorbed from the tears into the stroma, giving a cloudy appearance to the eye. The most common cause of a corneal ulcer is trauma. Less common causes of corneal ulcers include bacterial infections, viral infections, and other diseases.

A cough is an expiratory effort producing a sudden, noisy expulsion of air from the lungs. In cats, coughing is most often a sign of an inflammatory problem, affecting the lower respiratory tract, especially some form of bronchitis, often due to an infection. Heartworm infection, allergies, presence of foreign material within the airway, or irritation from inhaled liquids or gases can all be responsible for coughing and respiratory problems in cats. In order to diagnosis the cause, blood tests, laboratory cultures, endoscopic examination, and radiography may be performed. Treatment depends on the diagnosis and your cat's medical condition.
