The word OCT is an abbreviation of Optical Coherence Tomography and similarly, OCTA means Optical Coherence Tomography Angiography. These are two latest investigating tools, used in the diagnosis of certain eye diseases. The OCT and OCTA machine provides three-dimensional (3D) imaging of the anterior segment, retina, and optic nerve head (similar to a C T Scan of the eye) allowing early diagnosis and timely management of eye disorders.
