Biomicroscopy of the eye - Causes, symptoms and treatment. MF.

Biomicroscopy of the eye is a method of detailed examination of eye environments and eye tissues with the help of a special device - slit lamp. The slit lamp combines an intense light source and a microscope, which allows the

• to visually inspect eyelids, conjunctiva.
• Allows you to examine the structure of the cornea, its thickness, to reveal the nature and localization of pathological changes in it;
• allows you to examine the state of moisture in the anterior chamber of the eye( the space between the cornea and the iris), determine the depth of the anterior chamber;allows a detailed examination of the iris;
• allows to study the structure of the lens, to determine the presence and location of opacities in its substance;
• and also with the help of this method it is possible to examine the front half of the vitreous body mass and to reveal opacities, blood or various pigment deposits in it.

Slit ray of light allows you to examine the structure of the eye as if in a cut, which makes it possible to precisely localize the pathological process.

Indication of biomicroscopy:

1. Any pathology of the eyelids( inflammation of the eyelids or glands of the eyelids, edema, various anomalies, tumors, trauma).
2. Various diseases of the conjunctiva( inflammatory, allergic, cysts, tumors).
3. The pathology of the cornea and sclera( keratitis, corneal dystrophy, scleritis, corneal and sclera abnormalities).
4. Various pathologies of the iris( inflammatory diseases, structural abnormalities)
5. Injury to the eye.
6. Cataract.
7. Glaucoma.
8. Foreign cornea( removal operation).
9. Endocrine diseases.
10. Pre- and postoperative examination.
11. Evaluation of treatment effectiveness.

Contraindications to biomicroscopy:

Inadequate behavior of the patient( severe mental illness, alcoholic or narcotic intoxication).

Carrying out the

procedure This method does not require any special preparation. But if the lens and vitreous body are to be inspected, 15% before the procedure it is necessary to drip 0.5% of the tropikamid for children under 6 years of age, adults 1% of the tropicamide. In inflammatory diseases of the cornea or in traumas with a violation of its integrity, the coloring of the r-rum fluorescein or the r-rum of the Bengal rose. To do this, the dye is instilled in the conjunctiva cavity, and then washed with any eye drops, while the paint is washed off from intact areas and stains areas with damaged epithelium. Before the removal of foreign body in the eye instill r-r lidocaine.

The examination is carried out in a darkened room. The slit lamp is located on the table, which has a special headstand. The patient sits at this table and places his chin in this delivery, and his forehead tightly presses against the transverse bar. The doctor sits down from the back of the device, sets the necessary position, brightness, width of the light beam and inspects through the microscope. Applying various types of lighting, the doctor can detect minimal changes in the tissues of the eye. A ray of light can be expanded to a full circle to illuminate the entire surface of the eye or narrowed to the finest slit. During the inspection, the head should be immobile, it is not forbidden to blink when viewed, but it is necessary to try to do it as rarely as possible.

The duration of the biomicroscopy procedure is on average 10 minutes.

The procedure does not have any complications, but allergic reactions to the preparations used to prepare it are possible.
