The digital camera photographs the back of the eye and as a diagnostic tool enhances the detection of any abnormality, resulting in optimum patient care. In the same way that a dentist uses x-rays as part of the dental care process, so the retinal camera provides the optometrist with critical information and a record of any changes that have occurred between examinations.
