A technology first described in the 1990’s – Optical Coherence Tomography (OCT) – is making the diagnosis and management of retinal eye diseases that much easier.
The eye is a complex sensory organ that enables us to interact visually with our environment. One important component is the retina, which is situated at the back of the eye.
The retina is a multi-layered tissue that “captures” light and “converts” the visual input into electrical impulses that are transmitted to the brain. The brain then reinterprets the impulses as images that we see.
Assessing retinal diseases can be quite a task. It’s not like you are able to detect any problems with the naked eye.
Hence, tools to help diagnosis and track treatment are very important for retinal eye diseases.
One such tool is optical coherence tomography (OCT).
It’s essentially a non-invasive imaging test that “takes” cross-section pictures of the retina in all its glorious detail. Hence, each of the retina’s distinctive layers can be seen.
This is of great help to the eye specialist (ophthalmologist), who can then map and measure the thickness of the respective layers of the retina.
Such measurements can help with the early detection, diagnosis and treatment guidance of retinal diseases such as diabetic retinopathy and age-related macular degeneration.
The technology was first described in the early 1990s, and was initially used mainly in managing eye disorders as it allowed precise imaging of the retina……
