A picture is worth a thousand words. When it comes to ocular imaging, an optometrist can thoroughly examine the eye providing an in-depth assessment of the overall health of the ocular structures.
OCT
Our Heidelberg Spectralis Optical Coherence Tomography (OCT) device is a piece of diagnostic equipment that takes a series of advanced 3D scans of the back of the eye. These 3D scans of the optic nerve, retina and macula are highly detailed and allow us to view the granular structures of your eye, allowing for a more thorough and accurate examination of your eye health.
OCT is one of the few devices that reveals in-depth images of the eye’s internal structures. The exam only takes a few seconds. Nothing touches your eyes as you look into the machine and there are no puffs of air or flashes of bright light.
The scans can reveal potential abnormalities and help us to detect eye diseases such as age-related macula degeneration, glaucoma and diabetic eye disease in their earliest stages.
Having accurate scans of the back of your eye not only helps us develop a treatment plan tailored to your specific requirements, but also allows us to monitor any changes in your eye health over time.
Ultra-Widefield Retinal Imaging
An ultra-widefield retinal image gives us a huge 200° range within a single scan, four times more than most other retinal cameras. This Optomap technology captures a single image covering more than 80% of your retina, and up to 97% using automated software montaging of multiple images.
If the retina, the delicate layer lining the back of the eye, is damaged, it may affect your vision. Ultra-widefield retinal imaging helps us identify any issues and also reveals any blood vessel abnormalities that could indicate early signs of disease.
Corneal Topography
Corneal topography provides us with the most detailed possible information about the curvature of the cornea (the transparent part in the front of the eye), potential eyesight issues, and eye diseases.
Corneal topography is an established and important technology for measuring the shape and power of the cornea. It allows practitioners not only to fit contact lenses to match the power and shape of the cornea, but it also helps them to evaluate the intricacies of the contact lens’ relationship with the ocular surface. This is especially necessary for the prescription of orthokeratology lenses.
The greatest advantage of corneal topography is its ability to detect conditions that cannot be identified using most conventional testing. Identification of deep or superficial corneal disorders/distortions causing visual disturbances and impairment, such as keratoconus, a disorder in which there is progressive thinning of the cornea making it bulge outwards like a cone resulting in blurry vision, double vision, and short-sightedness.
Meibography
Meibomian gland dysfunction, or MGD, is one of the most common causes of an abnormal tear film lipid layer and evaporative dry eye, with numerous factors reported.
Meibography, imaging of the Meibomian glands, allows us to better assess the function of the small glands located through each eyelid using infra-red photography. We are also able to assess the impact of different treatments by comparing before and after images.
