Retinal photography, or fundus photography, is a process that optometrists and ophthalmologists use to take detailed pictures of the back of your eye (the ocular fundus).
This sophisticated tool allows eye care professionals to examine your eye health more closely and spot any problems that would otherwise be impossible to notice.
Retinal photography works by taking high-resolution digital photos of the inside of your eye. This imaging system captures a detailed record of the inner, light-sensitive layer of the eye called the retina.
Eye health professionals can use images like the one show above to observe the blood vessels going in and out of the retina, and draw important conclusions about the state of health of your eyes.

It is especially advisable for people who have a history of high blood pressure, diabetes, headaches, retinal diseases, vision symptoms like flashing lights, or strong eyeglass prescriptions.
This form of eye screening is simple, quick and painless.
Even people in good health are strongly recommended to have retinal photography included in an eye examination, since it provides eye health professionals with a good reference point for future comparisons.
