What Does an OCT Scan Do?
At our eye care practice, we are able to provide patients with retinal imaging and optical coherence tomography (OCT) by using the latest technology in vision care.
- Scans of the inner layers of the eye
- Cross-sectional images of the retina so each layer can be seen
- Specifically Optic nerve and Macula
- Can detect the earliest signs of disease before they are apparent
- Macular degeneration
- Diabetic retinopathy
- Serves as baseline measurements in healthy eyes so changes can be tracked over time
- Helps guide urgency of referrals to specialists
- Helps determine individual risk for development/progression of disease
- Non-invasive, no radiation waves emitted uses light waves to get 3D images
Visual Field Testing
During a routine comprehensive eye exam, your optometrist may want to perform visual field testing to assess the full horizontal and vertical range and sensitivity of your vision. Visual field tests are used to detect blind spots (scotomas), which could be a sign of eye diseases. The size and shape of a scotoma offer important clues about the presence and severity of diseases of the eye, optic nerve and visual structures in the brain. Many eye and brain disorders can cause peripheral vision loss and other visual field abnormalities.
For example, optic nerve damage caused by glaucoma creates a very specific visual field defect. Other eye problems associated with blind spots and other visual field defects include optic nerve damage (optic neuropathy) from disease or damage to the light-sensitive inner lining of the eye (retina).
Brain abnormalities such as those caused by strokes or tumors can affect the visual field. In fact, the location of the stroke or tumor in the brain can frequently be determined by the size, shape and site of the visual field defect.
