Scans
At our eye clinic, we are committed to providing comprehensive eye care through a variety of advanced eye scans designed to assess and monitor eye health effectively. Our state-of-the-art technology allows us to detect a wide range of conditions early, ensuring that our patients receive the most appropriate treatment. Here are the scans we offer:
OCT scan of Retina
An OCT (Optical Coherence Tomography) scan of the retina is a non-invasive imaging test that captures detailed, cross-sectional images of the retina. This scan uses light waves to visualize the different layers of retinal tissue, allowing eye specialists to detect and monitor conditions such as macular degeneration, glaucoma, and diabetic retinopathy. It's quick, painless, and helps in assessing the overall health of the retina to guide effective treatment options.
B Scan
A B-scan, or brightness scan, is an ultrasound imaging test used to examine the eye and the structures behind the retina. This test is especially useful when the view to the back of the eye is blocked by issues like cataracts or bleeding. It uses high-frequency sound waves to create a two-dimensional cross-sectional image, helping eye specialists diagnose and monitor conditions such as retinal detachment, tumors, or foreign bodies in the eye. The B-scan is painless and provides valuable information about the eye's internal health.
Corneal Topography
Corneal topography is a non-invasive imaging test that maps the surface curvature of the cornea, the eye's outermost layer. This test creates a detailed, color-coded map showing the cornea’s shape and thickness, which helps in diagnosing and managing conditions like keratoconus, corneal scarring, and irregular astigmatism. It’s also useful in planning surgeries like LASIK and fitting specialized contact lenses. Corneal topography is quick, painless, and provides essential information for assessing the eye's refractive surface.
Optical Biometry
Optical biometry is a non-invasive test that accurately measures the eye’s anatomical features, such as the length of the eye, corneal curvature, and anterior chamber depth. Using light waves, this test is primarily performed before cataract surgery to calculate the power of intraocular lenses (IOLs) required for clear vision post-surgery. Optical biometry is quick, painless, and provides precise measurements essential for achieving optimal surgical outcomes and ensuring proper vision correction.
Fundus photography
Fundus photography is a non-invasive imaging test that captures detailed color photographs of the retina (fundus), including structures like the optic nerve, macula, and blood vessels. This test helps eye specialists detect and monitor retinal conditions such as diabetic retinopathy, macular degeneration, glaucoma, and other vascular disorders. Fundus photography is quick and painless, offering clear images that allow for accurate assessment of the retina’s health and long-term documentation for tracking changes over time.
Common FAQs
Are eye scans painful or uncomfortable?
Most eye scans are non-invasive and painless. During an OCT scan or fundus photography, patients may be required to look at a specific target while the scan is performed, but no discomfort should be felt. Some tests may involve the use of dilating eye drops, which can temporarily blur vision and cause light sensitivity but generally do not cause pain.
​
How often should I have eye scans?
The frequency of eye scans depends on individual risk factors, age, and existing eye conditions. For those with a history of eye diseases, such as glaucoma or diabetes, more frequent scans may be recommended. Generally, routine eye examinations, including scans, should occur at least once a year, but patients should follow the guidance of their eye care professional based on their specific needs and health status
What types of eye scans are available and what do they detect?
There are several types of eye scans, including Optical Coherence Tomography (OCT), Fundus Photography, and Visual Field Testing. OCT provides detailed cross-sectional images of the retina, helping to detect conditions like macular degeneration and diabetic retinopathy. Fundus photography captures images of the interior surface of the eye, allowing for the examination of the retina and optic nerve for abnormalities.
