Keratoconjunctivitis sicca(KCS) of dog disease is an eye condition that occurs when the tear production is deficient. The cornea is transparent, and the outermost layer of the eye, like other tissues, needs oxygen and nutrients, but it is not supplied by blood circulation, but by the action of three layers of tear film. The outermost The layer is an oily layer, which is produced by the glands of the eyelid; the middle layer is a water-like layer, which is produced by the lacrimal gland of the upper eyelid and the gland of the third eyelid. KCS disease often occurs because it affects the function of this gland. The innermost layer is the mucus layer, produced by the goblet cells of the conjunctiva. KCS is the loss of the tear film, which leads to the drying of the cornea. When the cornea is dry, it will lack oxygen and nutrients, which will soon lead to the destruction of the structure, which will lead to the pigmentation of the cornea, scars, ulcers, and Hyperplasia of blood vessels.

Causation of this dog disease:

There are many reasons that are related to KCS. These include too little thyroid hormone secretion, such as infections caused by canine plague, and abnormalities in the lacrimal gland caused by immune-mediated diseases. The cause of many cases is still uncertain, but the treatment can still be carried out. Other common causes include drug poisoning, because these drugs are used to treat other diseases. KCS can be treated by replacing other drugs. If drugs cannot be changed, the KCS must also be treated or controlled.

Diagnosis of the dog disease:

Diagnosis is based on medical history, clinical symptoms and a series of diagnostic procedures. These include (SCHIRMER TEAR TEST) measurement of tear production and fluorescent test paper staining. This is a check to check whether the cornea is damaged and the time of tear diffusion. In addition, Bengal red staining may be used to assess the quality of the outermost layer of the cornea. Cytological examination is used to determine the type of conjunctival cells, which is important for prognosis and treatment.

Treatment of dog disease:

Medication therapy is the main treatment of KCS and can be used for a long time. Cyclosporine and tacrolimus are both topical eye medicines used to promote tear production. Replacement of topical medication with tears usually takes several times a day. If there is corneal ulcer or infection, local antibiotics should be prescribed.
