OPTICAL COHERENCE TOMOGRAPHY (OCT)
OCT is an indispensable exam nowadays, which is used to quantify, qualify and make therapeutic decisions in pathologies related to Glaucoma, Age Related Macular Degeneration (AMD), Diabetic Macular Edema, Central Serous Chorioretinopathy, Macular Hole, and other pathologies of the retina and optic nerve.
This examination allows us to create images very similar to histological sections, which are then used to examine, in detail, the structures of the inner and outer layers of the macula and optic nerve. The device works on the same principle as ultrasound, but uses electromagnetic waves, in this case a visible beam of light instead of ultrasonic waves.
OCT is a rapid examination and is completely noninvasive; neither the device nor examiner needs to touch the patient in order to perform the examination.
