Optical Coherence Tomography (OCT) is a non-invasive diagnostic instrument used to image the retina. It is excellent at detecting problems in the eye prior to any symptoms being noticed by the patient. With an OCT, doctors are able to see a cross section or 3D image of the retina and detect the early onset of many eye conditions and diseases such as macular degeneration, glaucoma and diabetic retinopathy (the top three diseases known to cause blindness).
The OCT allows for detection of other diseases such as macular holes, hypertensive retinopathy and even optic nerve damage. Using an OCT allows for early treatment and dramatically improves the success of these treatments especially in diseases such as wet macular degeneration – where the eye disease progresses rapidly.
The OCT has become the standard of care for the assessment and treatment of most retinal diseases; it is similar to a CT scan which is used to image internal organs inside the body. At San Juan Eye Centers we have the newest OCT technology available in our Montrose office.
