In this section, by using modern equipment and facilities, a thorough evaluation of the anterior segment of the eye is provided. Some of these assessments include:
Orb scanand Pentacam: By this system corneal topography, the overall structure of the cornea, includingsurface strength, thickness and shape of the anterior and the posterior is determined. This is one of the techniques that can be used to evaluate the posterior part of the cornea.
Pachymetry: Corneal pachymetry is the process of measuring the thickness of the cornea by using ultrasound technique. Itis a fundamental procedure before refractive surgeries such as LASIK, in which parts of corneal tissue are removed.
Topography: In this technique multiple concentric lightrings are projected on the cornea. After capturing the reflected image, creating topographic maps and analyzing the data, it is possible to identify any cornea abnormalities such as Keratoconus, scarring and irregular astigmatism, moreover the corneal curvature can be calculated. Topography is also invaluable in evaluating patients, particularly those who want to undergo a refractive surgery corneal curvature such as LASIK. Postoperatively, topographymay be necessary in follow up procedure insome cases.
Confo scan: This technique can be used to evaluate the cornea before surgery, early diagnosis of Keratoconus, endothelial analysis(the innermost layer of the cornea), determining the depth ofepithelial layer that is set aside in some surgeries and epithelial layer study (surface layer of the cornea) can be used.
Equipment used in this technique: topography systems EyeSys, anterior segment analysis system Orbscan Slit-scanning, ZywaveWavefrontAnalyzer, WaveScanWavefront System, ALLEGRO Oculyzer, ALLEGRO Topolizer, imaging devices, PentacamScheimpflug Imaging.
Visual Cortex Examination
VEP or Visual Evoked Potential: Most of the time,testing visual potentiality of children is problematic, therefore some special tests such as ERG and VEP are used. These two tests can provide information on the visual pathway-from the eye to the brain-for ophthalmologists. While watching a flashing light oran objectmoving or suddenly appearing, an electrical responseis emitted from brain's visual section. Measuring this electrical response is the basis of VEP. To perform this test, electrodes are attached to the back of child's scalp (poop).
