What is a fundus camera used for?
A fundus camera is a complex optical system used for imaging the retina of the eye. Retinal imaging presents a unique difficulty considering that the retina must be illuminated and imaged simultaneously, a process which forces illumination and imaging systems to share a common optical path [1-3].
How does fundus imaging work?
Simultaneous stereo fundus cameras use one exposure to place two images side by side on a single 35mm frame. Light generated from either viewing lamp or the electronic flash is projected through a set of filters and onto a round mirror. This mirror reflects the light up into a series of lenses which focus the light.
What is mydriatic fundus camera?
It is a kind of retinal camera allowing ophthalmologists to view the retina more deeply and store the results for further research and comparison. More importantly, doctors and patients can view more explicit images for more in-depth disease analysis and further treatment.
What is a non mydriatic camera?
A non-mydriatic fundus camera: Makes use of the retina’s reflective properties to show details and store images that are superior to slit lamps and other commonly-used tools. Does not require pupil dilation in the majority of cases, and is painless for patients.
Why Fundus examination is done?
This test is often included in a routine eye exam to screen for eye diseases. Your eye doctor may also order it if you have a condition that affects your blood vessels, such as high blood pressure or diabetes. Ophthalmoscopy may also be called funduscopy or retinal examination.
Where is the fundus of the eye?
Fundus is the bottom or base of anything. In medicine, it is a general term for the inner lining of a hollow organ. The ocular fundus is the inner lining of the eye made up of the Sensory Retina, the Retinal Pigment Epithelium, Bruch’s Membrane, and the Choroid.
Which fundus camera is best?
In the overall ranking, the Zeiss was superior and in 90% better than the median (Bonferroni corrected p-value = 0.04). Optos was better than the median in 60%, Canon in 40% and Topncon in 10%. Conclusions : Each of the evaluated fundus camera has particular strengths.
How much is a retinal camera?
True, a retinal camera costs in the ballpark of $19,000 to $24,000, but it can provide an excellent means of monitoring diseases of the optic nerve and retina.
What is normal fundus?
Normal Fundus. The disk has sharp margins and is normal in color, with a small central cup. Arterioles and venules have normal color, sheen, and course. Background is in normal color. The macula is enclosed by arching temporal vessels. The fovea is located by a central pit.
