OCT is used as the standard of diagnostic care for a wide range of retinal and macular conditions, including macular degeneration, diabetic retinopathy, macular puckers, and macular edema. OCT allows your doctor to diagnose and monitor retinal conditions by measuring the retina’s thickness and observing the retina’s different layers. Optical coherence tomography (OCT) is a non-invasive imaging test that uses light waves to capture high-resolution images of the retina. Fluorescein angiography is often used in the diagnosis of diabetic retinopathy, retinal vein occlusions, and macular degeneration. Once the dye has reached the eyes, a camera is used to capture images of the retinal vascular system and observe any abnormalities. Fluorescein Angiographyįluorescein angiography is an imaging technique that uses a special, light-sensitive dye injected into the bloodstream to highlight the ocular blood vessels. Retinal Imaging Testsĭiagnostic retinal exams rely heavily on advanced imaging techniques to identify the presence of retinal, macular, and vitreous conditions. We recommend that patients plan on having someone drive them home after their exam. Blurred vision is also common after a dilated eye exam, as well as trouble focusing on fine details. Eye dilation typically lasts for about 4-6 hours and can make your eyes more sensitive to light. Once the eye drops are administered, it takes about 15-30 minutes for your eyes to become fully dilated. The eye drops help to keep the pupils open and allow your doctor to see your retina, macula, and optic nerve. When in the presence of bright light, the pupil becomes smaller, which would make it difficult for ophthalmologists to properly observe the inside of the eye. Pupils are the black circles at the center of our eyes and their primary function is to control how much light enters the eye. During a dilated eye exam, special eye drops are applied to the eyes to keep the pupils from getting smaller. Dilated Eye Examĭilated eye exams are a crucial part of retinal diagnostics and testing. During this exam, there are several diagnostic testing modalities that may be performed to help determine the presence, location, and severity of damage or illness. To evaluate retinal health, your doctor will conduct a thorough diagnostic exam to look for damage and abnormalities in the eye.
