This can affect your vision, but can be repaired by surgery. Macular hole: A macular hole happens when your retina pulls apart forming a hole in your macula.Macular pucker: Scar tissue can grow over the surface of your retina causing distorted vision.Your macula is the part of your retina that has the most light-sensing cells. Cystoid macular edema : Macular edema refers to the swelling of your macula with fluid.People can become completely blind, but with treatment, diabetes-related retinopathy can be controlled. In severe forms, your entire retina can detach from the back of your eye and glaucoma may develop. Fluid can leak out of your eye causing blurry vision. Diabetes-related retinopathy : Diabetes damages the small blood vessels of your eye leading to vision loss.It’s a progressive disease related to aging but, fortunately, treatments are available for some forms. Age-related macular degeneration : People may lose central vision with this condition.Glaucoma : If you have glaucoma, fluid and pressure build up in your eye and damage your optic nerve.Healthcare providers use OCT to diagnose and manage several conditions that affect the eyes, including:

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.
