Keratitis

Keratitis (keritis) - inflammation of the cornea.

Etiology. The cause of the disease can be mechanical, chemical, infectious, invasive, neurogenic effects, and also symptomatic - myt, foot and mouth disease, metritis, malignant fever, equine influenza, dog plague, etc. Keratitis is divided into superficial (conjunctival) according to the histological structure of the cornea deep (parenchymal) and posterior; by clinical and morphological changes - catarrhal, vascular, aphthous, pustular, purulent, neurotrophic, dystrophic and parenchymal.

Clinical signs. Common to all forms of keratitis are corneal clouding of the eye, pericorneal vascular hyperemia, impaired gloss and specularity, photophobia, a sharp increase in sensitivity, eyelid spasms, exudate secretion.

For the surface catarrhal keratitis is characterized by the release of mucous exudate, on the cornea can be eroded. With superficial vascular keratitis, blood vessels form on the cornea, the opacification is gray-red, granulation tissue may form; with purulent - there is a discharge of purulent exudate from the palpebral fissure, the formation of blood vessels on the cornea is possible; with fluktenuleznom - education on the cornea of ​​small elevations with slightly turbid contents, with dystrophic - the cornea loses sensitivity, ulcers appear in the center, which decrease or increase. Parenchymal (deep) keratitis can occur in two forms: limited (as an abscess) and diffuse (diffuse) with damage to the entire cornea. When an abscess first forms a small infiltrate, and then an abscess. When diffuse cornea necrosis occurs, ulcers, fibrin overlay, vascular germination. When back keratitis opacification is observed from the inner surface of the cornea, the outer surface is smooth and shiny.

The diagnosis is made on the basis of clinical signs. The prognosis for superficial keratitis is often favorable, for deep ones it is cautious.

Treatment. Eliminate the causes of the disease. Animals give rest. Conduct toilet eye, infraorbital blockade by Gatin. Apply trivitamin, retinol. When an abscess of the eye should be an abscess after anesthesia open. The rest of the treatment, as with purulent conjunctivitis.

Infectious keratoconjunctivitis. Acute infectious disease of the cornea and conjunctiva of the eye. It can occur in the form of an enzoi with a lesion of up to 80–90% of the livestock.
The causative agent of the disease is rickettsia (Rickettsia cojunctivae bovis). More often young cattle are sick, but sheep, pigs, horses can be ill. Carriers of the pathogen are flies, ticks, etc. The incubation period lasts 3–10 days. Initially, catarrhal conjunctivitis and parenchymal keratitis of one eye develops, and the second is also affected by stalemate. Subsequently, the cornea becomes yellow-red, an abscess forms in its center, and then an ulcer. There may be a complete perforation of the cornea. The duration of the disease is 20–35 days. After recovery, a scar is formed in the eye.

Forecast cautious.

Treatment. Patients are isolated in a dark room, the eye is washed with a solution of furatsilin (1: 5000), eye drops (0.5% solution of zinc sulfate and 3% solution of boric acid), infra-ocular gatin blockage is performed, Novocain-chlortetracycline ointment is injected ( novocaine - 5.0, chlortetracycline - 5.0, petrolatum - 90.0), syntomycin emulsion (10%), protargol (5%), corticosteroid ointment with antibiotics, solutions and albucide ointment. Dry heat recommended.

Invasive keratoconjunctivitis. Telazioz - worm disease of the eye (conjunctiva and cornea) and the lacrimal-nasal canal. They are ill with cattle, less often horses, sometimes pigs and dogs. It flows in the form of enzootia. The causative agent is the nematode Thelasia rhodesi (most commonly distributed in the west), Thelasia gulosa (in the east), Thelasia skrjabini (in the east and south).

The first was found under the conjunctiva and the third century, the second and the third in the ducts of the lacrimal gland. The intermediate owner is a fly.

Clinical signs. As a rule, the disease is widespread. Starts catarrhal conjunctivitis, and then goes into the purulent and the cornea. In prolonged cases, ulcers form on the cornea, then scars and cataracts.

Diagnosis. With mass surveys of cattle can be found in the conjunctival sac of parasites.

Treatment. The eye is washed with a solution of Lugol (1: 1000), 3% solution of boric acid. Washing is repeated every 2–3 days. It is better to wash the nasolacrimal canal. In the formation of ulcers and walnut good effect give novocainic blockade of the eye, tissue therapy.

Prevention. Since June, in dysfunctional farms, clinical examinations of the herd are carried out 2 times a month. Detected diseased animals are isolated and treated. They also fight with flies.

Keratitis

  1. Keratitis
    Keratitis is an infectious inflammatory disease of the cornea. Keratitis is characterized by pain, often severe, a decrease in visual acuity and intense tearing. See the article EYES (PROBLEMS), with the addition that a person experiences anger and distress, and also holds back tears, although his emotional body is in dire need of them. See also page.
  2. KERATIT
    Keratitis or inflammation of the cornea develops as a result of various mechanical damage — scratches, pricks, etc. In addition, keratitis appears as a complication of some infectious diseases, as well as under the influence of helminthic invasion. In case of untimely and improper treatment, the cat may lose sight on the affected eye. Distinguish superficial, deep, ulcerative
  3. "Red Eye" (with pain)
    Acute keratitis Acute keratitis is an inflammatory process in the layers of the cornea. Causes are corneal microtraumas, viral or bacterial infections. CLINICAL PICTURE Complaint ¦ pain; ¦ photophobia; ¦ blepharospasm; ¦ pain in the eye area; ¦ decreased vision. Symptoms detected during physical examination: ¦ red eye symptom - mixed injection of blood vessels in the form of a “purple halo”
  4. Late congenital syphilis
    Late congenital syphilis is considered by many authors as a relapse of syphilis, suffered in infancy or early childhood. Manifestations of late congenital syphilis are found not earlier than 4-5 years of age, more often at 14-15 years, and sometimes later. Lesions of the skin and mucous membranes in the form of lumpy and gummous syphilides are no different from similar lesions when acquired
  5. CURRENT CENTURY
    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,
  6. Visual impairment and visual pathway
    Cornea. The cornea, the main refracting surface of the eye, is highly sensitive to the damaging effects of the environment (direct injury, drying, radiation and ionizing radiation), infectious agents (bacteria, viruses, especially herpes simplex viruses and shingles, fungi, parasites), inflammatory processes, sometimes combined with common skin conditions such as
  7. Late congenital syphilis
    Vrozh-e sif manifestations. maybe later 4-5 years from the moment of birth. Clinic: appeared bump-ulcerative syphilides and gum (skin of the body, limbs, face). Hillocks can be grouped without fusion. Hillocks and gumma may disintegrate forming ulcers that are located on the mucus. about. nose can perforate the nasal septum. Reliable signs - Getchinson's triad: keratitis, labyrinthitis, Getchinson's teeth.

  10. Vaccine eczema
    Complication of eczema, or neurodermatitis, developing 5–10 days after ope-priming or contact with a vaccinated person. Children are ill mainly. However, vaccination against chickenpox is still not widespread. The onset is acute, with a violation of the general condition, the temperature rises to 40 ° C. Rash of vesicular-pustular elements with an impression in the center of eczematous foci and near

  12. Epithelial dysplasia
    DEFINITION The disease is characterized by a defect in the basement membrane, a violation of the attachment of the enterocyte. This leads to the formation of clusters of enterocytes: rounded enterocytes are located on top of each other without contact with the basement membrane. Assume the presence of pathology desmosomes. ICD-R78.3 CODE Noninfectious diarrhea in the newborn. CLINICAL PICTURE The clinical picture reminds
  13. Ear syphilis
    Manifestations of secondary syphilis (roseola, papule) on the skin of the outer ear are observed simultaneously with a similar lesion of other skin areas. The greatest value in syphilis of the ear has a process localized in the inner ear. There are congenital and acquired forms of the disease. In the congenital form, damage to the inner ear is found at the age of 10–20 years and it manifests itself in a triad.
  14. Infectious and parasitic diseases and tuberculosis

Give one correct answer: 11.01 The characteristic symptoms of fulminant meningococcemia do not include: A) a fever with a tendency to decrease; B) exsicosis of II-HI degree; B) oligoanuria; D) the progression of vascular and respiratory disorders; D) metabolic acidosis. 11.02. A symptom typical of the catarrhal period of measles is not:. A) fever; B) runny nose; B) dull cough;
  15. EYE INFECTIONS
    CLASSIFICATION The main clinical forms of eye infections by localization are conjunctivitis (66.7% of the total number of patients with inflammatory diseases of the eye) and blepharitis (23.3%), keratitis is less common (4.2%). Conjunctivitis Conjunctivitis can be divided into fulminant, acute and chronic by the rate at which symptoms develop. Lightning Conjunctiva is urgent
  16. SYPHILIS OF ORGANIZATIONS
    Eye damage is noted in the secondary period of syphilis, most often in the form of iritis. Patients complain of pain, photophobia and lacrimation. On examination, pericorneal injection, constriction of the pupil and sluggish reaction to light and convergence are detected. On the iris, a rash of small, larvae with a pinhead, papules is often noted. Damage resulting from
  17. AUTOIMMUNE DISEASES
    An autoimmunopathy is a condition caused or maintained by immune responses that develop against its own blood cells or tissues. Tolerance of immunity to the body’s own structures disappears. It is believed that either a dysregulation of the immune response occurs, or some tissues acquire the nature of antigenicity as a result of exposure to endogenous or
