At Jackson’s Opticians we can now offer Fundus Photography to all our patients. These pictures help to document the health of the back of the eye including structures such as of the optic nerve, retina, macula and retinal blood vessels. The photographs are stored for comparison on future visits to the practice and therefore greatly enhance our record keeping and allow us to monitor and identify any trends.
Because Fundus Photography is a highly specialised form of medical imaging, it can’t be done with an ordinary camera. It requires a customised camera that is mounted to a microscope with intricate lenses and mirrors. These high-powered lenses are designed so the optician can see the back of the eye by focusing light through the cornea, pupil and lens. The patient is asked to stare at a flashing light so the eyes are still while the optician is taking the pictures, the patient will see a series of bright flashes. The entire process usually takes just a few minutes.
Usually a good image can be obtained without the use of eye drops but occasionally they are necessary to make the pupils big enough to obtain the best results. These drops smart only slightly and your pupils will go back to their normal size in about 4 to 6 hours. While your pupils are dilated it is advisable not to drive as sunlight can appear more dazzling than normal and sometimes the drops can make your near vision slightly blurry, again the effect wears off after a few hours.
