The following equipment allows us to offer our patients a comprehensive and detailed examination:
- Zeiss IOL Master
- Humphrey Visual Field Analyser
- Topcon OCT Scan
- Alcon Ocuscan
- Oculyser (Corneal Topographer)
OCT – Optical Coherence Tomography
Is a non-invasive imaging test that uses light waves to take cross-sectional pictures of:
– The retina; This is the nerve layer that lines the back of the eye.
– The optic nerve; which transmits visual information from the retina to the brain.
With OCT, each distinctive layer can be seen, allowing us to assess the retinal thickness, and ocular structures in detail.
Why is it required?
These measurements are helping with early detection, diagnosis and treatment guidance for retinal and optic nerve diseases and conditions.
The OCT is useful in diagnosing and managing many eye conditions, including:
The principle of the Visual Field is to test the peripheral (side) vision. This will assist your ophthalmologist diagnose any peripheral visual. This can be used to diagnose various eye disorders e.g. glaucoma; but can also assist in the diagnosis if neurological disease eg stroke or brain tumors.
During the examination, there is no contact with the eye, and no pain is felt. Each eye is tested separately. Therefore one of your eyes is alternately patched during the test.
You are asked to look straight ahead at a fixed spot and to watch for light targets to appear in your field of vision. When you see the target, you press the indicator button.
Your ophthalmologist will interpret the results and discuss them with you.
If you are diagnosed with a particular disorder or disease, visual field tests may become a routine part of your follow up. Especially in glaucoma patients where follow up field tests may be done every six or twelve months to make sure that the condition is stable and no further vision loss has occurred.
