Digital retinal photography
Mae'r cynnwys hwn ar gael yn Saesneg yn unig.
Digital retinal photography or fundus photography is a sophisticated process that uses a digital camera to take detailed pictures of the back of your eye.
We use it to document the health of the optic nerve, posterior pole, macula, retina and its blood vessels. We also use it to keep a permanent photographic reference of your eye health so we can review it again when you come back to see us next time.
We use fundus photography to monitor the progression or diagnosis of diseases, and also in screening programmes.
You can have a fundus photograph as part of your routine eye exam. If you are an NHS patient, you will have to pay £10 to have the photograph taken.
