The optics of fundus camera is similar to indirect ophthalmoscope and light travels through number of lenses. These are advanced and critical devices manufactured by some top companies like Topcon, CSO, CenterView and many more. Every procedure can be easily carried out but missing appointments is not recommended as there is a procedure performed before the test where dilation of pupils takes place. Because of that, vision gets blurred or hazy for short interval and the bigger retina area can be diagnosed carefully. Bright light passes through retina and image gets captured.

Images captured by fundus camera helps examine parts of retina that gets illuminated. Numerous benefits are offered by such photography as images are evaluated for diagnosing different ailments like retinal detachment, glaucoma, etc. The papilledema detected by this photography shows intracranial pressure signs that take place because of different issues like brain tumor, hypertension, etc. The advancements made in the areas of science and technology introduces new equipments essential for treating patients suffering from serious eye diseases.

There is no doubt about the fact that fundus camera is an important tool for eye doctors for diagnosing the diseases effectively. Prior to the introduction of such equipments there were hardly any simple procedures available to detect eye diseases. But the inception of such instruments proves beneficial for majority of people as every problem is detected without mistakes. Ophthalmology is an area which requires high precision equipments as details of the disease are not visible from the outside. One major advantage of such instruments is that they can be used easily, effectively without losing precious time. As more number of diseases affects people, the future of a healthy and happy lifestyle depends a lot on these devices.

Retinal camera or the fundus camera is an important diagnosing tool for eye ailments. The retina is the most important part of the eye since it is the place where the image is formed and the image is transmitted to the brain for analysis and image formation. The retina is much akin to the photographic plate in any camera.  A retinal camera is a camera with a microscope and an eyepiece for viewing the image of the retina. Fundus camera or the retinal camera can also photograph the image of the retina.

A Fundus camera unlike an ordinary camera which gives about 50 degrees of the retinal area and a 2.5X magnification provides a 140 degree view of the retina and 5X magnification.  The retinal camera uses a system of lenses through which light is focused on the retina after passing through the cornea. The light is then reflected by the retina and traces a different path to the eyepiece. Since the paths of the incident and the reflected light are different, there is no risk of the two mixing up and causing any distortion.

Ophthalmic equipment like the retinal camera finds a number of applications. The camera is used to take colour pictures of the retina for studying any anomaly in the structure. The camera is also equipped to filter off the red colour so that the blood vessels are more clearly visible since the blood vessel will appear dark in any other colour except red colour. The camera can also be used for retinal angiography. A florescent or contrasting medium is introduced in the blood vessel so that the fine vessels in the retina are visible and any blockages can be seen clearly.
