Contemporary Ophthalmological Diagnostic Equipment
Modern models of diagnostic devices from the world’s leading manufacturers of ophthalmic equipment allow for highly accurate diagnosis of eye diseases, treatment of almost any degree of complexity, as well as ensuring the possibility of high-quality monitoring after the treatment or in the postoperative period.
For example, the new topcon cv 5000 computer phoropter model allows you to do three things in a matter of minutes:
- measure visual acuity;
- choose glasses;
- determine vision pathology.
The following key types of our equipment can be noted.
GDx Nerve Fiber Analyzer
The GDx (short for “glaucoma diagnosis”) device scans the retina in about one second, creating a map detailing the thickness of the retinal nerve fiber layer in the central part of the retina, particularly in the area surrounding the optic nerve. GDx allows the diagnosis of glaucoma precursors. The use of the device is considered to be the only method for early detection of glaucoma today, allowing treatment to begin before vision loss occurs.
Keratotopography is a painless, non-contact diagnostic method. The result of corneal topography is a color map of the ocular surface, on which healthy and pathologically changed areas of the cornea are marked. Keratotopography of the eye cornea allows to detect existing irregularities on the ocular surface, determine the direction of visual meridians and their degree of expression. This is the only technique that can detect keratoconus, in which the cornea becomes cone-shaped.
Optical Coherence Tomography
Optical coherence tomography or OCT is a diagnostic examination of the structures of the eye that uses special equipment called a coherence tomograph. In the course of the examination the layers of the retina are scanned with a light beam, which allows to determine changes in the retina, detect edema, dystrophies, inflammatory processes, hemorrhages, etc.
Digital Retinal Camera
The retinal camera takes a picture of the retina, the light-sensitive part of the eye. The camera produces a bright flash when you take the picture. The resulting image can help identify serious visual impairments, such as vascular diseases or retinal detachment.
Digital Anterior Segment Imaging
Detailed high-resolution imaging of all structures of the anterior segment of the eyeball from the anterior surface of the cornea to the posterior surface of the lens. Important parameters such as anterior and posterior corneal curvature, total corneal optical power, pachymetry, anterior chamber depth, 360° anterior chamber angle and corneal and lens densitometry are calculated automatically.
An innovative system for visual electrophysiological examination. The visual evoked potential system measures the functional responses of the visual pathway from the anterior segment of the eye to the visual cortex. The test results can be used in the diagnosis of glaucoma, amblyopia, and other retinal diseases.
Microscopy / Endothelial cell evaluation
Endothelial microscopy is a density count as well as a qualitative analysis of the posterior corneal epithelium cells to evaluate its waterproofing function. The microscope automatically counts the number of endothelial cells per unit area of the cornea. It is also capable of determining cell shapes and sizes. Numerous external influences can disrupt corneal endothelium metabolism and thereby damage the cornea itself: eye surgery, airtight contact lenses, chemicals, medications, harmful substances in the air. Endothelial microscopy helps to identify the extent of such damage and plan treatment.
Computerized Visual Field Analyzers
Two different types of automated (computerized) visual field analyzers used in our practice are the Humphrey Frequency Doubling Technology and the Humphrey Visual Field Analyzer. Each of these eye perimetry instruments are involved in determining the visual field and identifying where abnormalities exist.
This precise instrument combines two different instruments.
An auto refractor provides data on the refraction of the eye – an analysis of its optical properties in order to clarify pathologies such as hyperopia, myopia or astigmatism.
The keratometer allows for keratometry, which includes analysis of the curvature of the front surface of the cornea for timely detection of eye diseases such as keratoconus, and in selecting and determining the optical power of contact lenses.
Corneal Ultrasound Pachymetry
Corneal pachymetry is a method of measuring corneal thickness at one or several points using ultrasound. Pachymetry allows assessing the degree of corneal edema in endothelial dysfunction and decreased corneal thickness in keratoconus.
Non-contact tonometry is a method of calculating intraocular pressure. Portions of air of a certain strength are directed at the patient’s eye. Under its influence the cornea is applanated (or flattened) – it bends inward slightly, but this is counteracted by the intraocular pressure. The sensors in the tonometer record the degree of corneal deflection. The device gives the results, by which the doctor determines the state of intraocular pressure.
Goldmann Applanation Tonometer
Goldmann tonometry is considered one of the most accurate and reliable methods of determining intraocular pressure. This technique allows for a painless and relatively quick determination of the pressure level and an accurate diagnosis of the patient.
It helps to detect glaucoma, retinal detachments, hemorrhages, various pathologies and diseases.
Slit lamp biomicroscopy
Biomicroscopy of the eye is a method of non-contact examination of the eye, its optical media and tissues using a slit lamp. A slit lamp is a special ophthalmic microscope with an illuminating device. The described device creates a linear beam of light that allows the doctor to examine all structures of the eye under high magnification: eyelids, conjunctiva, cornea, sclera, anterior chamber, iris and lens. As a result, the doctor receives information for diagnosis.
Meibomian Gland Disease treatment
The treatment of meibomian gland dysfunction and consequently the prevention of conjunctival-corneal xerosis development is performed in a complex: eyelid hygiene (warm compresses, eyelid self-massage), increasing blink frequency, tear replacement therapy; aimed at restoring the lipid layer of the tear film, which simultaneously reduces the negative environmental factors on the eye surface, improves corneal nutrition and increases the protective properties of the tear layers.
