Diagnostic Facilities

Hospital facilities of the Filatov Institute include up-to-date equipment for diagnosis and effective management of eye diseases. Specialists of the Institute use both standard and modern computer and ultrasonic methods. The high degree of accuracy ensures identification of the most complex diseases at any stage.

Aberrometry - a technique to measure eye tissue imperfections or abnormalities based on the way light passes through the eye which affects the ability of the eye to focus properly

Visometry (Visual Acuity Test) includes all the necessary diagnostic tests, enables to determine the vision acuity with maximum accuracy and to choose the best correction. It is a principle of diagnostic ophthalmic set

Keratometry is measuring the curvature of the anterior surface of the cornea , particularly for assessing the extent and axis of astigmatism

Keratotopography – the test indicates homogeneity and roughness of the cornea and enables to exclude or diagnose a disease. Keratotopography gives a topographic image of the anterior corneal surface

Computer perimetry - the world standard for glaucoma diagnosis. It is used to examine central and peripheral vision as well as to measure contrast and threshold sensitivity of the retina. It is important for early detection , diagnosis and follow - up of many ocular conditions including glaucoma

Confocal microscopy is a technique enabling to investigate the cornea with tissue visualization at the cellular and microstructural level. It allows to visualize the corneal tissue, to measure the thickness of each layer and to evaluate morphological disorders

Microperimetry – combined use of Computer Perimetry and retinal examination with Fundus Camera

Optical Coherence Tomography (OCT) - a gold standard in diagnosis of the retina and optic nerve diseases. It can easily be described as ultrasound with light and it enables to visualize small structures and layers inside the tissue with a resolution of about 10 µm. With this resolution and an imaging depth of about 2 mm inside scattering tissue OCT fills the diagnostic gap between ultrasound and microscopy. In contrast to ultrasound OCT does not need any contact to the tissue

Pachymetry is the process of measuring the thickness of the cornea

Rheo-ophthalmography – the technique enables to evaluate the choroidal hemodynamics. Rheo-ophthalmography is convenient to control the effectiveness of hypotensive, vasoactive and metabolic preparations being used in the eye diseases treatment

Retinal Tomography enables to detect early defects of optic nerve head and nerve fiber layer in glaucoma-suspect patients. It is also optic neuropathy monitoring

Refractometry – is a technique for the measurement of refraction; it enables to detect the refraction (type and degree) and all the parameters of the cornea as accurate as possible

Spectral Optical Coherence Tomography - highly informative method of diagnosis which enables to get information on the state of the retina and optic nerve and indicate their changes at an early stage of disease

Tonometry, tonography – a contact technique for measurement of intraocular pressure with digital indication of results in mm Hg. Hydrodynamic indices may be determined according to the data of the measurements.

Ultrasonography

Ultrasonic A-scanning is identifying anterior chamber depth, lens thickness, eyeball and vitreous length including those in opaque environments. A scanning enables to evaluate the progression of myopia, to calculate the size of artificial lens, to determine the presence and height of the intraocular reticular neoplasm.

Ultrasonic B-scanning is designed for investigation of internal structures of the eye. It is used for diagnosis of retinal detachment, vitreous body changes, eye and orbit tumors and determining their volume and spread

Ultrasonic Biomicroscopy is a technique of acoustic visualization of the internal structures of anterior segment of the eye (the cornea, iris, anterior chamber angle and lens).

Fluorescein angiography - is a technique for examining the circulation of the retina and choroid using a fluorescent dye and a specialized camera. It involves injection of sodium fluorescein into the systemic circulation, and then an angiogram is obtained by photographing the fluorescence emitted after illumination of the retina.

Phosphene diagnostics enables to determine the electrical sensibility and lability of the retina.
