Optical coherence tomography (OCT - acronym of "Optical Coherent Tomography" ) is a very innovative imaging technique, which "takes" high-resolution photographs of the retinal tissue, providing information on the thickness, conformation and relationship between various layers that make it up.
What is it for?
Optical coherence tomography is a non-invasive diagnostic imaging exam that exploits the reflection of infrared laser beams to scan the retina, dividing it into tissue sections (just like any tomography). The exam then returns a series of images in high resolution, in color or in black and white.
Optical coherence tomography provides very important information on the retina, as it is able to highlight the layers of this suffering ocular structure. The examination allows, in particular, to study in detail the macular region and the optic papilla .
OCT is considered an instrumental investigation complementary to fluorangiography and can be useful for furthering interpretative doubts about unclear ophthalmic lesions. Scans are generally performed for all diseases affecting the retinal region, including age- related macular degeneration ( AMD ), glaucoma and diabetic retinopathy .
