I. Introduction to the disease
Keratitis is a common eye disease in dogs with many causative factors. It can be divided into several types of traumatic, superficial, parenchymal and septic keratitis. The etiology is mostly due to trauma blows, pressure, irritation from sharp objects or foreign bodies accidentally introduced into the eye. The disease can be induced by corneal exposure, bacterial infection, nutritional disorders, and the spread of adjacent tissue lesions.
In addition, keratitis can be complicated in the presence of certain infectious diseases canine infectious hepatitis or cloudy eye disease. The common symptoms of keratitis are shyness, tearing, pain, lid closure, corneal clouding, and corneal edema. Mild keratitis is often not easily detected directly, but can only be seen under oblique sunlight with a rough and uneven corneal surface. Traumatic keratitis can often be scarred, with the clear surface turning light blue or blue-brown. Depending on the type and force of the object causing the injury, traumatic keratitis can appear as superficial, deep, or penetrating corneal wounds. For thermal injuries caused by chemicals, only the corneal epithelium is disrupted in mild cases, forming a silvery gray turbidity, or ulcers in severe cases.
