Introduction

As we make our way through preliminary testing, let’s take a moment to review fundus photos. Fundus, meaning inside of the eye; primarily the retina, the optic disk, and retinal vessels. Photos are captured during this segment of the eye exam. So, these images are captured through a single lens system that typically captures 30 to 50-degree views of the retina and optic nerve and usually with predetermined flash intensity settings already set up on your camera.The overall concept is that this is a low power microscope with an attached camera. It utilizes an aerial image system of focusing and allows you to see further out into the periphery. Fundus photos can be performed with colored filters or with specialized dyes. These images allow the doctor to reference, notate, and measure any changes, resulting in better assessment and treatment plans. This can help in detecting cataracts, retinal defects, and other conditions.
