Inflammation of the eyelids
Etiology. Inflammation of the eyelids may be due to a variety of causes. The most common cause is irritation of the eyelids as a result of mechanical, thermal or chemical effects. If the integrity of the skin is compromised, microbes, parasitic fungi can penetrate, which leads to the appearance of parasitic and infectious diseases. Inflammation of the eyelids can cause various complications of wounds, bruises, burns; The inflammatory process can shift to the eyelids and from surrounding tissues. Some predisposing causes of some forms of blepharitis include a general metabolic disorder, exhaustion, avitaminosis, especially A and C. Clinically, surface blepharitis is distinguished when the edge of the eyelid is involved in the inflammatory process, and deep - with damage to the subcutaneous tissue, muscles and other tissues of the century.
Deep blepharitis occurs more often as a complication due to contamination and infection of wounds, abrasions and eyelid bruises. In other cases, the development of deep inflammation occurs as a result of transition from surrounding tissues. It occurs in the form of a diffuse phlegmonous process with a tendency to the formation of an abscess. Special forms of blepharitis, such as gordelium (barley) - purulent inflammation of the hair follicles of the eyelashes. Proliferative inflammation of the meibomian glands, in horses and cattle are rare, they are more likely to suffer pigs, dogs and cats.
Superficial blepharitis can be scaly and ulcerated. Both species can be stages of the same process.
Clinical signs. With scaly blepharitis, which is usually chronic in nature, at the onset of the disease, the edge of the eyelids and the adjacent area of the conjunctiva are hyperemic, itchy, and foamy exudate accumulates in the inner corner of the eye. Itching causes animals to scratch their eyes on surrounding objects, as a result of which the eyes are often injured. The edges of the eyelids thicken, the eye slit narrows. Easily removable grayish scales or crusts form at the base of the eyelashes. Eyelashes with the course of the disease fall out. There is always tearing. Complication of scaly blepharitis may be the transition of inflammation to meybomiyevye glands, and due to the deposition of connective tissue in the thickness of the eyelid may be inversion or inversion of the latter and visual impairment. With timely treatment, the disease has a favorable outcome.
Ulcerative blepharitis unlike flaky proceeds in a more acute form. In the development of this disease, purulent microorganisms, in particular staphylococcus, which can be found in large amounts in pus under crusts, are of particular importance.
The edges of the eyelids swell, hyperemia, become covered with pustules. Opening, pustules form yellow crusts, under which there is pus. At removal of crusts ulcers are found. In mild cases, some parts of the margin of the eyelids are affected and the ulcers are found only in certain places. In more severe cases, the entire edge of the eyelid is covered with sores and pustules; it is wet and bleeds easily.
With a prolonged course of the disease, the eyelashes fall out and even completely disappear due to the destruction of their bulbs (madarosis); sometimes when scarring sores, they can take a direction inside the eye (trichiasis). The edge of the century is thickening and drooping. Persistent tearing and eversion of the eyelids develop.
Phlegmonous blepharitis is often a one-sided phenomenon. Bilateral phlegmon of the eyelids is observed in some infectious diseases, for example, in malignant catarrhal fever of cattle.
According to the clinical signs and course of phlegmon, the eyelids are no different from phlegmons in any other part of the animal's body. The usual outcome of phlegmon of the eyelids is the formation of abscesses with their breakthrough through the skin to the outside or, more rarely, towards the conjunctival sac. In some cases, especially with low resistance of the microorganism and high virulence of the pathogen, phlegmon of the eyelids may be generalized and cause sepsis. This is facilitated by a very rich vascularization of the eyelids and the surrounding tissue.
Phlegmon of the eyelids may be limited with damage to only the tissues of the eyelids or, spreading, to capture the surrounding subcutaneous tissue of the forehead, nose and facial part. In the first case, the eyelids swell significantly, become tense, painful and hot; their consistency is densely elastic; The skin is significantly tense and does not fold. The swollen conjunctiva is strongly hyperemic, even cyanotic, covered with purulent exudate. Conjunctival swelling can reach a considerable size, and then it bulges out of the palpebral fissure. There is purulent mucous discharge from the eyes. Body temperature can be increased. When spilled form swelling captures the surrounding area, goes into orbit and face skin. The eye slit is closed. With deep palpation of the eye is not detectable. After 5–7 days, due to purulent fusion of fiber, palpation can be used to soften the swelling and then fluctuation — an abscess is formed, which is opened by itself. After the abscess is opened, the tension in the eyelid tissues decreases, the purulent cavity is relatively quickly cleared of the remnants of necrotic tissues and is performed by granulation tissue. Subsequently, it is scarring, which can lead to the deformation of the century.
Forecast. With appropriate treatment - from favorable to cautious.
Treatment. Eliminate the root cause. Assign good nutrition and maintenance. Next, you need to protect the animal from scratching (dogs are made by collars of cardboard, horses and other animals are tied up on stretch marks or metal mesh caps over their eyes). Crusts are removed by treating with antiseptic solutions. The ulcers are cauterized with a 1% solution of brilliant green or lapis lice. For purulent blepharitis, 5% chlorotetracycline novacain ointment is prescribed. If required, intramuscular administration of antibiotics is prescribed.

Inflammation is a biological, and at the same time, a key general pathological process, the expediency of which is determined by its protective-adaptive function, aimed at eliminating the damaging agent and restoring the damaged tissue. In medicine, to indicate inflammation to the name of the organ in which the inflammatory process develops, add the ending "it" - myocarditis, bronchitis,

Inversion of the eyelids is a pathological condition in which the edges of the eyelids turn inward towards the eyeball, contributing to the trauma of the conjunctiva and the cornea. In Persian cats, this is a congenital defect that occurs quite often. Quite often, an eyelid twist develops as a complication of chronic conjunctivitis. Symptoms: increased tearing, eye canal narrowed, cornea cloudy,

Chronic inflammation characterized by 1. amyloid deposition 2. mononuclear infiltration
Inversion of the eyelids may be in all animals, but most often it is observed in dogs. In this disease, the plane of the free edge of the eyelids, which normally adjoins the eyeball evenly, all or for some extent turned inward. With a strong degree of torsion, not only the free edge, but also the skin surface of the eyelid together with the eyelashes is turned to the eye, which causes irritation of the cornea. AT
- Inversion century
Etiology. When inverting, a part or all of the edges of the eyelids turn out and move away from the cornea. Causes of eyelid reversal are: 1) damage with a large tissue defect (wounds, burns, eczema, dermatitis), when the scar tissue that develops at the injury site delays the edge of the eyelid outward - cicatricial reversal; 2) diseases of the conjunctiva, when much edematous tissue pushes the edge of the eyelid from the eye -

The course of inflammation is determined by the body's reactivity, the type, strength, and duration of action of the phlogogen. There are acute, subacute and chronic inflammation. Acute inflammation is characterized by: - intense and relatively short (usually 1-2, up to a maximum of 4-6 weeks) duration (depending on the damaged organ or tissue, the extent and scale of their alteration,

Inflammation always begins with cell damage and death. But at a certain stage, when the processes of repairing damage, cleansing from all the dead, alien to the body enter into force, infiltration, suppuration and the associated processes of proteolysis and necrosis stop and recovery processes come to the fore. In accordance with this, the cellular composition of the inflammatory
