It has zero point in a routine exam in the office except to make money. It's literally taking a photo of what the doc should be looking at on their exam. I only use it when I want to document the exam for the future.

In screening, it can be useful because some patients don't have easy access to an eye doctor. One of the ophthalmologists in my residency read retinal images from across the VA. He'd decide if a patient needed to go in for an actual exam for diabetic retinopathy or something.
