OPTICAL COHERENCE TOMOGRAPHY

 

Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to take cross-section pictures of your retina, the light-sensitive tissue lining the back of the eye.


With OCT, each of the retina’s distinctive layers can be seen, allowing us to map and measure their thickness. These measurements help with diagnosis and provide treatment guidance for glaucoma and retinal diseases, such as age-related macular degeneration and diabetic eye disease.

 

Retinal Photography

fundus

A digital camera is used to capture a photograph of the back surface of your eyes. This high resolution image provides a detailed view of important structures such as the retina, optic nerve, macula and blood vessels. These photos can be compared at subsequent visits in order to readily identify any subtle changes that can occur to the health of your eyes over time.

Retinal photographs are invaluable for diagnosing and monitoring many sight-threatening eye diseases, including glaucoma and macular degeneration. In addition, general medical conditions such as diabetes and hypertension frequently result in retinal disease that can be detected with this technology.

 

 

Corneal Topography

Corneal topography is used to precisely map the shape of the cornea, the front surface of the eye. The image is similar to a land contour map, depicting colour-coded areas that differentiate relative changes in steepness.

Topography is generally performed on all contact lens wearers, patients considering refractive surgery and patients with certain corneal conditions, such as keratoconus. It is also our preferred method for following the changes that take place during corneal reshaping or ortho-K treatment.

 

 

Slit Lamp Photography

Slit lamp photography allows us to document the anterior (front) structures of your eyes, such as the cornea, conjunctiva, lens and iris. This technique is also valuable for custom contact lens fitting, allowing us to take images of lenses on your eye, in order to track any changes in the fitting characteristics.

 

 

 

 

Visual Field Test

Your visual field describes how much you can see around you, including objects in your peripheral (side) vision. The visual field test produces a map of your field of vision. An accurate record of the visual field allows us to reliably monitor for loss of peripheral vision including gradual loss over many years. The visual field test assists in the diagnosis of a range of eye diseases, including: 

  • Glaucoma
  • Optic nerve damage
  • Retinal disorders
  • Neurological conditions
  • Brain disorders (including stroke)
