Fundus photography



Fundus Photography involves capturing a photograph of the back of the eye i.e. fundus. Specialized fundus cameras that consist of an intricate microscope attached to a flashed enabled camera are used in fundus photography. The main structures that can be visualized on a fundus photo are the central and peripheral retina, optic disc and macula. Fundus photography can be performed with colored filters, or with specialized dyes including fluorescein and indocyanine green.The models and technology of fundus photography has advanced and evolved rapidly over the last century. Since the equipments are sophisticated and challenging to manufacture to clinical standards, only a few manufacturers/brands are available in the market: Topcon, Zeiss, Canon, Nidek, Kowa, CSO and CenterVue are some example of fundus camera manufacturers.
