Conjunctivitis means inflammation of the conjunctiva. If you see excessive tearing or watering from one or both eyes, abnormal discharge, or reddened conjunctival membranes, your cat may have conjunctivitis. The most common causes of conjunctivitis can be roughly divided into two categories: infectious diseases and non-infectious conditions including allergies, hereditary conditions, and tumors. Conjunctivitis may also be a secondary symptom of another eye disease. Specific tests will be performed, based on the medical history and results of an eye examination and surrounding tissues. The general approach to non-specific conjunctivitis is to use ophthalmic preparations containing a combination of broad-spectrum antibiotics to control the secondary bacterial infection and anti-inflammatory drugs to reduce the inflammation. The prognosis depends on the specific diagnosis.
The cornea is the clear, glistening membrane that makes up the surface of the eyeball. A penetration or erosion through a few layers of the outermost corneal epithelium is called a corneal erosion or corneal abrasion. A corneal ulcer is a deeper erosion through the entire epithelium down into the stroma.
Hepatic lipidosis, also known as fatty liver syndrome, is unique to cats and is one of the most common liver diseases seen in cats. Usually a cat with hepatic lipidosis has recently gone through a period of anorexia. When fat is broken down rapidly to supply energy and nutrients to the anorectic cat, it can overwhelm the ability of the liver to process and the fat becomes stored in and around the liver cells, further compromising liver function. Diagnosis of hepatic lipidosis is made from blood tests that demonstrate poor liver function and from a liver biopsy or aspirate. This disease is treatable with aggressive nutritional support until a normal appetite returns.
