Digital retinal imaging has become a vitally important test, used for early detection of ocular diseases.
The images are stored electronically to allow your doctor to detect and measure any changes to your retina at each eye exam.
Retinal imaging is not a substitute for a regular eye exam, but enables a wider, and more precise view of your retina for early detection of ocular disease.
Retinal imaging facilitates early identification of the follow ocular diseases:
The DRI is now commonly performed as part of your regular eye exam. However, if you notice any changes to your vision, or vision loss, your eye doctor may wish to use a DRI test to rule out any ocular conditions that may be damaging your retina.
Additionally, if you have been diagnosed with any of the following conditions, your eye doctor may recommend a DRI test:
Since the retinal blood vessels are the only blood vessels in the body that can be seen by a doctor, the DRI test is also being used to detect general health conditions.
If you think you will benefit from a DRI contact an eye doctor near you.

Prior to beginning the test, your eye doctor may dilate your pupils with special eye drops. Your eye doctor will then ask you to place your chin and forehead on supportive rests to help you keep your head still.
Next, you will open your eyes as wide as possible and stare at an object straight ahead. A bright flash will be seen when the photograph is taken, capturing high definition images of your retina and optic nerve.
The images are displayed on a computer screen for your eye doctor to review with you.
In most cases, the DRI test is performed without any eye drops, but it’s always recommended to rest for a few minutes following the test, to allow the effects of the flash to wear off.
If your eye doctor recommends a DRI test, you can rest assured that this is a relatively quick and painless test.

These days, many eye care specialists offer retinal imaging, but most people are not sure if the service is necessary for them. Well, chances are that you may not need retinal imaging, but the test provides another way to examine your eye health in a more detailed way.
Retinal imaging can be helpful if you are at high risk for retinal illnesses. Your eye doctor may recommend the test if you have diabetes, retinal toxicity, macular degeneration, or glaucoma. Please note that the test is not a substitute for a regular eye checkup. It allows a broader and more accurate look at your retina to detect eye diseases early.
Retinal imaging is a painless diagnostic exam that uses a high-resolution camera to take colored pictures of the back of your eye. The pictures give your doctor a closer look at the inner parts of your eye and help them take note of changes to your eye health and vision. Your optometrist can use optical coherence tomography (OCT), angiography, or fundus photography techniques to examine your eye.
Pictures of the back of your eye will show your retina, blood vessels, and optic nerve. The images let your eye doctor detect certain eye or health issues and treat them early to prevent them from becoming severe. Retinal imaging is non-invasive and appropriate for all ages. Here is why the test is necessary.
With retinal imaging, your doctor can see symptoms of eye conditions that could not be detected before. Eye conditions such as diabetic retinopathy, glaucoma, age macular degeneration, and detached retina can be detected with retinal imaging.
All these eye illnesses need quick medical care to prevent vision loss. Moreover, retinal imaging is a computerized procedure. This means that any retina-related diseases are automatically examined, diagnosed, and saved by a computer. This leaves little room for human error.
Signs of high blood pressure or hypertension, diabetes, and some forms of cancer are first evident in the retina. This is well before other signs appear throughout the body. Detecting such health issues early is vital in treating them. This retinal imaging can mean the difference between a fast and easy solution and a more widespread, problematic treatment.
Retinal imaging uses a computer to examine, diagnose, and store the results of your test. This enables your eye doctor to compare your test results every year during your annual eye exam. This aspect of retinal imaging is important in monitoring treatment outcomes. It also tracks the progress of diseases and notices any irregularities quickly.
There is no good reason to avoid taking the test during your annual comprehensive eye checkups. Retinal imaging is fast and painless, and its benefits outweigh its costs. Think of it as your first line of defense against numerous different threats to your health.
