Only 10 years ago OCT technology was mainly used in research, but recent advances in the technology have brought this to the forefront of eyecare.
This revolutionary technology is quite common in eye hospitals but this top level of care is available in only a few private consulting rooms or High Street optometry practises.
Pabari Opticians have invested to ensure that the very best technology is available to protect your eyesight now, and in the future.
This test is not part of the NHS Eye Test but is performed as part of an Extended Eye Examination.
OCT (Optical Coherence Tomography) utilises complex technology used to create images of the eye and, in particular, the layers of the retina. The retina is the light sensitive area at the back of the eye, equivalent to film in a camera or CCD in a digital camera.
An OCT scan is similar to a CAT scan for the eyes.
OCT can image in 3D allowing your practitioner to see problems within your eye that could not easily be seen before.
The test is very quick, simple and is completely non- invasive. (There are no sudden puffs of air or light flashes.)
Any areas that may appear atypical can then be measured. Later repeat scans can be compared with the original so any changes can be seen and measured.
The retina can be damaged by many common diseases like Glaucoma, Diabetes and Age Related Macular Degeneration.
Damage to the retina can lead to visual impairment or even blindness.
By using the OCT your practitioner can pick up any problems at a much earlier stage, usually allowing you better treatment options and a better visual outcome.
High definition data and advanced analysis provide precise registration critical for glaucoma detection and management.
Here is a typical HD-OCT scan & map of a healthy retina, followed by scans of eyes with common problems.
