High-Tech Equipment to Assess Ocular Structure and Function
Our patients have access to a complete set of the latest investigation equipment for the detection, diagnosis and monitoring of a full range of ocular pathologies. All investigations are done by qualified technicians and optometrists in a friendly and professional setting and they include:
- Optical biometry
Takes fast and precise measurements of the eyeball axial length and corneal curvature and performs advanced intraocular lens power calculations before cataract surgery.
- A-scan ultrasound biometry
Takes measurements of the eyeball axial length and performs intraocular lens power calculations. It is mainly used for dense cataracts before surgery.
- Optical coherence tomography (OCT)
Takes high resolution cross-sectional images of the anterior and posterior segments of the eye. It is commonly used to diagnose and follow-up macular diseases and to measure nerve fiber layer thickness around the optic nerve head for the diagnosis and follow-up of glaucoma. It is also used to assess anterior segment structures before intraocular surgery.
- Digital fluorescein and indocyanine green angiography
Images the posterior segment of the eye and provides information about the blood circulation in the retina and underlying choroid. It is mainly used for the management of retinal vascular diseases, posterior segment inflammation and age-related macular degeneration.
- B-scan ultrasonography
Produces two-dimensional cross-sectional views of the eye and the orbit. It is mainly used in the diagnosis and follow-up of vitreoretinal diseases.
- Corneal topography
Produces computer-assisted maps of the anterior and posterior surface curvatures of the cornea and provides information on corneal thickness, refractive powers, distortion and irregularities. It is used in the preoperative assessment and screening of patients undergoing refractive surgery and for the diagnosis and management of corneal diseases.
- Visual field testing
Detects, measures and identifies the pattern of any visual loss anywhere in the central and peripheral visual fields. It is used for the diagnosis and follow-up of glaucoma and certain neurological deficits.
- Electroretinogram (ERG)
Records the electrical response of the retina and provides information about its function when different light patterns are flashed into the eye. It is mainly used for the diagnosis and follow-up of inherited retinal and choroidal diseases.
- Electrooculogram (EOG)
Measures the resting potential of the eye and assesses the function of the retinal pigment epithelium under the retina. It is used for the diagnosis and follow-up of inherited retinal diseases.
- Visual evoqued potential (VEP)
Detects and measures the response evoked in the visual cortex due to a change in visual stimulus. It reflects the activity of the whole visual pathway from the retina to the visual cortex and is used to help determine a patient's level of visual acuity.
