It shows the retina (where light and images hit), the optic disc (a spot on the retina that holds the optic nerve, which sends information to the brain), and blood vessels. This helps your optometrist or ophthalmologist find certain diseases and check the health of your eyes.
You sit in front of a special camera and in a flash a digital image is obtained. Observation of the image allows us to view blood vessels on the retina, the macula and the optic nerve. It allows us to closely monitor how key structures in the eye change over time.
By examining your eyes in this way, your eye doctor can often detect conditions such as diabetes, high blood pressure, arterial plaque, multiple sclerosis, brain tumors, stroke, leukemia and many other conditions.
it helps in the identification and diagnosis of disease and abnormalities involving your retina and optic nerve, like glaucoma, macular degeneration, and changes due to diabetes to name a few. it allows the optometrist to educate you about your eye health, specifically by showing you any issues visible on the photo.
Your eyes act as an early warning system to let you know when something is wrong and you need medical attention. Diabetes, for instance, can cause blurred vision when symptoms began to flare up. Dim or double vision may be an early sign you are suffering a stroke. Blood vessels are especially revealing.
Opticians can find this condition through doing a thorough eye examination and using a slit lamp stereoscope. They will examine the eye to see if there is any yellowing of the Cataracts. Surgery is not always the primary reaction to this condition but it will be considered with more serious cases.
Fundus photography is a specialized medical imaging test used to take pictures of the structures located at the back of the eye, including the retina. It produces a series of photos that are helpful for diagnosing, documenting, and monitoring certain eye conditions.
These pictures help us identify problems with your vision, and can also help diagnose other medical conditions such as high blood pressure, diabetes, cholesterol, or even brain tumors. Digital retinal photography is important because often vision or eye problems can develop with no clear symptoms.
A regular, routine eye test can sometimes detect eye problems that indicate the presence of a brain tumour before any symptoms become obvious. An eye test is particularly good at identifying any swelling of the optic disc (a condition called papilloedema) and can also identify when there is pressure on the optic nerve.
A liver that is working poorly cannot get rid of bilirubin, a substance that produces a yellowing of the eyes and skin called jaundice. Too much alcohol and some medicines can also lead to jaundice. If you suddenly develop jaundice, you should go to the emergency room immediately.
Visual assessment of OCT signals based on the criterion “loss of normal attenuation” allows tumors to be distinguished from the cortex during in vivo scanning (10, 23).
OCT scans are especially helpful for the early detection of the sight-threatening eye disease, glaucoma, which shows few symptoms until it is advanced, as well as age-related macular degeneration, retinal detachments, and diabetic retinopathy.
It lets them see the retina (which senses light and images), the optic disc (where the optic nerve takes the information to the brain), and blood vessels. It lets your doctor check for diseases and other eye problems.
After the test
You can go home when the test is finished. For up to 6 hours after the test: your sight may be blurry – do not drive until it goes back to normal. everything can look very bright – wearing sunglasses can help.
A regular vision exam can help detect a stroke before it happens, especially in older individuals. Diabetes: Diabetes affects the small capillaries in the retina of the eyes. These blood vessels may leak blood or a yellowish fluid, and this may be discovered in an eye exam.
Ophthalmoscopy. During this examination, your doctor shines a bright light into your eye and examines the structures at the back of your eye. This eye test evaluates the optic disk, where the optic nerve enters the retina in your eye. The optic disk becomes swollen in about one-third of people with optic neuritis.
