Before starting our main topic, let us have a basic anatomy session. Our eyeball is made of several structures and tissues. The back part of this eyeball is called the fundus, which comprises a retina, optic disc, and blood vessels. The retina is the main portion of the eyeball where an image of the things you see forms. Image is then converted to nerve signals that travel all the way via the optic disc and optic nerve to be perceived by the brain.
Isn’t eye functionality interesting and beautiful? Well, of course, it is! This article aims to let you know about retinal fundus photography and its various advantages.
Retinal Imaging Technology and Fundus Photography
Fundus is the site of many pathological conditions. Thus, doctors and ophthalmologists must be able to look at the fundus clearly for correct diagnosis. This problem was solved by the use of modern equipment that allows the ophthalmologist to look at the back or fundus of your eye.
Nowadays, an ophthalmologist can even take a 2-D picture of the fundus and store it in the computer for future use by the use of a technique called retinal fundus photography. This retinal imaging technique utilizes a low-power microscope attached to a high-resolution camera for photographing the retina or the back of the eye. The photo will show the patient’s retina, optic disc and blood vessels clearly for the purpose of assisting your optometrist in finding specific eye or health conditions and preventing serious disease progression.
Retinal imaging allows ophthalmologist to capture more than 80% of the retina at a time, therefore a comparision of the previos eye conditions and comprehensive treatment are available.
Optical coherence tomography, fundus photography and angiography all of the methods used by retinal imaging technology, and each has its own advantages.
Functions and Advantages of Fundus Photography
Almost every ophthalmologist is using retinal fundus photography for visualizing the retinal structures with the development and maturment of the technology. fundus photography is a kind of retinal imaging technology that helps to enhance the assessment of eye health, all of which can make patients feel more at ease!
Fundus imaging is now more and more widely used in the medical industry. It is because:
- It is a non-invasive procedure without the risk of any complications. The patient will not feel any discomfort during the fundus photography eye test.
- The procedure is fast, efficient, and accurate. The diagnosis can be made almost immediately.
- It becomes easier to look into the details of the retina via the non mydriatic fundus camera rather than a direct examination of the eye.
- Doctors can get a full bird’s eye view of the retinal layers and associated structures which helps make the correct diagnosis.
- The most useful feature of this technique is that there isn’t any requirement for the dilation of the pupil before the procedure. This makes it non-mydriatic and risk-free.
- Different filters and dyes are also available for allowing retinal fundus photography in different colors.
Let us now have a look into the purposes of retinal fundus photography and see how it helps in diagnosie many eye-related pathologies. The following eye illnesses are diagnosed with the help of retinal fundus photography:
- Glaucoma: increased optic disc-to-optic cup ratio seen in the fundoscopic examination.
- Diabetic Retinopathy: macular edema, microaneurysms, and formation of new blood vessels (neovascularization) are diagnostic clues during the fundus examination.
- Hypertensive Retinopathy: Whitish cotton wool spots are seen on the nerve fibers of the retina.
How is fundus photography eye test conducted?
During the procedure of fundoscopic photography,
- An ophthalmologist will instruct patients to sit in front of the non-mydriatic fundus camera with chin placed on a chin rest and forehead against a firm attached bar.
- The camera would be focused and aligned on the pupil by the ophthalmologist.
- As soon as the shutter is released, the camera flash takes a photograph of the fundus of the eye.
- This eye can be stored in the computer for future use too.
It is also noteworthy here that the fundus photography test cost is not that expensive and is easily in the range of many individuals. In general, the fundus photography test cost can vary anywhere between 30$ to 60$.
The Bottom Line
To put all of this into a nutshell, retinal fundus photography is the latest non-invasive procedure to have a full fundus photographic examination. Are you wondering about the best funduscopic camera?
