OPTICAL COHERENCE TOMOGRAPHY (OCT)
This machine allows us to take 3-dimensional scans of the back and front of your eyes rather like an MRI scanner does for the rest of your body.
What are the benefits?
We can look beneath the retinal surface and detect:
Who should have OCT?
Everyone who wants the best available eye care but particularly:
Display of thin blood vessels in the conjunctiva:
Only the thin blood vessels of the conjunctiva are detected and evaluated.
Display in red-free light:
Under the green spectrum of visible light, blood vessels are richer in contrast and more visible.
Evaluation of the lipid layer thickness:
The colour and structure of the lipid layer is visible and can be recorded. This shows the lipid layer thickness, which correlates with tear film evaporation and dry eye symptoms. If the lipid layer is too thin or absent, the tear evaporation rate and the tear film instability increase.
Evaluation of the tear film break-up time:
The tear film break-up time measurement with the Keratograph 5M is touch-free and fully automatic. The new infrared illumination is invisible to the human eye and produces no glare during the examination and no reflex tearing. The TF-Scan maps the tear film break up time and is a great tool for follow-ups and patient consultation.
3-D display of the meibomian glands
There are different viewing options, such as, the 3-D display, various section planes and the marketing of the individual area of examination to easily evaluate the meibomian glands and the morphological changes in the upper and lower eyelids.
