Retinal imaging takes a digital picture of the back of your eye. It shows the retina (where light and images hit), the optic disk (a spot on the retina that holds the optic nerve, which sends information to the brain), and blood vessels. This helps Dr. Tan to find certain diseases and check the health of your eyes. Retinal imaging allows Dr. Tan to get a much wider digital view of the retina. It doesn’t replace a regular eye exam or regular dilation, but adds another layer of precision to it.
Dr. Tan may also use retinal imaging if your vision is getting worse and aren’t sure why.
