Electroretinography

Electroretinography is a method for recording the total bioelectrical activity of all retinal neurons: negative a-wave - photoreceptors and positive b-wave - hyper- and depolarizing bipolar and Mueller cells.

Pachymetry of the cornea

Pachymetry is the measurement of the thickness of the cornea. It is an indirect sign of the integrity of the corneal endothelium. The largest thickness of the cornea is near the limbus (0.7-0.9 mm).

Soskob and biopsy of the cornea

Scraping of the cornea is performed with a Kimura spatula, a curved end of the needle (for the hypodermis), or a blade. After instillation of a local anesthetic without preservatives, the edges and the bottom of the lesion (usually ulcers) are gently and carefully scraped under the control of the slit lamp.

Keratometry of the cornea

Kerometry of the cornea is the measurement of the curvature of the axial meridians of the anterior surface of the cornea.

Assessment of the sensitivity of the cornea

Assessment of the sensitivity of the cornea in order to identify gross violations of the sensitivity of the cornea.

Confocal intravital microscopy of the cornea

Confocal microscopy of the cornea is one of the modern methods of investigation; allows to conduct intravital monitoring of the cornea state with visualization of tissues at the cellular and microstructural level.

Biomicroscopy of the cornea

It is essential to systematically identify clinical signs, determine the localization, depth and size of corneal damage.

Conjunctiva study

Conjunctiva is easily accessible for research and diagnosis of many of its diseases, does not require any special equipment.

Examination of lacrimal organs

The marginal tear stream of both eyes is examined with a slit lamp before other manipulations on the eyelids or by instillation of local preparations that can change the clinical picture. Many patients with tearfulness do not have pronounced lachrymation, but when examined they are diagnosed with a high marginal tear stream on the affected side.

Investigation of the hemodynamics of the eye

The study of hemodynamics of the eye is important in the diagnosis of various local and general vascular pathological conditions. The following basic methods are used for the study: ophthalmodinamometry, ophthalmoplethysmography, ophthalmosfigmography, rheophthalmography, ultrasonic dopplerography.
