Uveit

An examination and evaluation for the involvement of inflammatory processes is performed in case of eye diseases with pronounced symptoms. Uveitis-a condition made in the presence of inflammation occurring on any section of the choroid:

  • The iris;
  • Choroid;
  • Ciliary body.

The main symptoms of uveitis are manifested in irritation and redness, palpable soreness, an unpleasant reaction to light (photosensitivity), spots in front of the eyes, lacrimation and loss of clarity of vision can be observed. Any alarming symptom is an unusual sensation, this is an occasion to contact an ophthalmologist as soon as possible.

Etiology and development of the disease

Any microorganism that can provoke inflammation can cause uveitis.What is more, their function is not primary: they are acting as provocateurs. The key explanations for this are a decline in immunity against a history of severe diseases and a body predisposition.

Inflammatory mechanisms in which patients turn to an ophthalmologist account for 30 to approximately 60 per cent of the disease varieties. The ailment can lead to partial or complete loss of vision with advanced forms and premature treatment, which happens in 25-30 percent of cases.

The eye's uveal tract is distinguished by a separate supply of blood to the anterior and posterior sections, a wide branching of the vessels with a very slow flow. Due to these structural features, microorganisms can linger in the choroid and provoke inflammation.

Disease classification

Depending on the localization of inflammation, several forms of the disease are distinguished:

  • Anterior uveitis: the most common form, the ciliary body, the iris are affected. Diagnoses: iritis, iridocyclitis, anterior cyclitis.
  • Median: retina, choroid, ciliary or vitreous. Diagnoses: parsitis, posterior cyclitis, peripheral uveitis.
  • Back uveitis: optic nerve, retina, choroid. Diagnoses: retinitis, choroiditis, chorioretinitis, neuroveitis.
  • A generalized form of the disease is noted with simultaneous damage to all parts of the choroid.
  • Ophthalmic uveitis can occur in different ways: there is a purulent, gemmarogic, fibrinous-lamellar or serous nature of the inflammatory process.
  • The etiology of the disease involves four forms: primary, secondary, exogenous and endogenous uveitis.

The clinical course of the disease determines how:

  • Acute uveitis;
  • Chronic uveitis;
  • Chronic recurrent uveitis.

Granulomatous and non-granulomatous species are also distinguished according to the morphological picture.
