Fundus Photography is a form of medical imaging which uses a specialised microscope with attached camera (called fundus camera) to painlessly photograph the inside of the eye. This allows for detailed colour images of the major structures of the retina or the back of the eye to be recorded including the macula (the highly sensitive central region of retina), optic nerve head (called optic disc), major blood vessels etc.
In order to get good quality pictures, your eyes would be given dilating drops so that maximum light enters the retina and your pupils do not constrict after the bright flashes of light. After your eyes have dilated sufficiently, you will be asked to place your chin on a rest, your forehead against a bar and stare at a fixation light. You will then see a series of flashes of light as the photographs of your retina are taken. After dilation, this does not take more than 5 – 10 minutes and is painless and easy The digital images can be seen immediately on the screen..
Fundus Photographs are visual records of your retina which help to study your retina and keep a check for changes in the future. It is done for early diagnosis and monitoring the outcome of treatment in a number of diseases including:
