What does optical coherence tomography do?

Optical Coherence Tomography is a noninvasive imaging technology used to obtain high resolution cross-sectional images of the retina. The layers within the retina can be differentiated and retinal thickness can be measured to aid in the early detection and diagnosis of retinal diseases and conditions.

What is optical coherence tomography OCT test?

Optical Coherence Tomography (OCT) is a non-invasive diagnostic instrument used for imaging the retina. It is the technology for the future because it can enhance patient care. It has the ability to detect problems in the eye prior to any symptoms being present in the patient.

What are the three types of Ophthalmic imaging?

In the past two decades eye care has seen the emergence of three major technologies for diagnostic imaging of the posterior segment of the eye: Scanning Laser Polarimetry (SLP), Confocal Scanning Laser Ophthalmoscopy (CSLO), and Optical Coherence Tomography (OCT).

How do I read my eye scan results?

In general, the further away from zero the number on your prescription, the worse your eyesight and the more vision correction (stronger prescription) you need. A “plus” (+) sign in front of the number means you are farsighted, and a “minus” (-) sign means you are nearsighted.

What is Ophthalmic imaging?

Ophthalmic imaging is a highly specialised field of ophthalmology which helps doctors to diagnose and manage a wide variety of eye conditions. This is a rapidly developing area, with new instruments and techniques allowing us to better understand eye diseases and their treatments.

What are ocular images?

Ocular imaging technologies allow quantitative assessment of the posterior segment to detect changes in the optic nerve head (ONH), the nerve fiber layer (NFL), and the macula that are associated with glaucoma.

What is OCT in coronary angiography?

Optical coherence tomography (OCT) is an optical analog of intravascular ultrasound (IVUS) that can be used to examine the coronary arteries and has 10-fold higher resolution than IVUS.

Does Medicare cover OCT scans?

No, OCT scan is generally not covered by Medicare. The only exception is the first OCT scan when patients with macular condition commence antiVEGF eye injection.
