When would optical coherence tomography be needed? Tumors in your choroid and retina: These cancers happen in your retina and your choroid, a vascular layer found between your retina and your sclera.When the condition worsens, you can have vision loss. Cone and cone-rod dystrophies: These conditions affect the cells of your eyes that are sensitive to light and color.This can affect your vision, but can be repaired by surgery.

Your macula is the part of your retina that has the most light-sensing cells.
#OPTICAL COHERENCE TOMOGRAPHY ANGIOGRAPHY PROFESSIONAL#
Your eye care professional suggests optical coherence tomography if they suspect you have certain conditions at your eye exam or if you already have a condition that they’re helping you manage. When is optical coherence tomography performed? Unlike traditional angiography, the test is completely noninvasive and a dye doesn’t need to be injected.

The dye used glows when exposed to a blue light.Įye care professionals can also use optical coherence tomography angiography to see inside the blood vessels in your eye. Eye care professionals also use a special type of angiography to examine blood vessels of your retina. Typically, your healthcare provider injects a radiopaque dye that shows up on the X-rays. Traditional angiography, also called arteriography, refers to examining the inside of blood vessels using X-rays. What is optical coherence tomography angiography? Healthcare providers in the dentistry, gastroenterology, pulmonology, dermatology and oncology fields are also using OCT imaging more often. Healthcare providers of heart and vascular medicine use optical coherence tomography for cardiac catheterization to produce images of your blood vessels. Optical coherence tomography can measure the thickness of your retina and optic nerve. The noninvasive method produces an image by measuring the amount of a dim red light that reflects off of your retina and optic nerve. Optical coherence tomography, or OCT, is an imaging method used to generate a picture of the back of your eye, called your retina.
