Fundus Photography
Don't be surprised if someday, your eye doctor orders photographs of the back of your eye. These pictures are necessary to document the health of the optic nerve, vitreous, macula, retina, and its blood vessels. Because fundus photography is a highly specialized form of medical imaging, it can't be done with an ordinary camera. It requires a customized camera that is mounted to a microscope with intricate lenses and mirrors. These high-powered lenses are designed so the photographer can visualize the back of the eye by focusing light through the cornea, pupil and lens.
Before beginning, the pupil is dilated with drops. The patient is asked to stare at a fixation device so the eyes are still. While the photographer is taking the pictures, the patients will see a series of bright flashes. The entire process usually takes five to ten minutes.

Heidelberg Retinal Topography
The Heidelberg Retina Tomograph is a confocal laser scanning microscope designed for three-dimensional imaging of the posterior segment of the eye. Due to its ability to produce highly accurate and reproducible topographic images, this sophisticated technology can most effectively be applied to the evaluation of Topograph at and around the optic nerve head. The main application is seen to be the detection and monitoring of change which occurs in glaucoma.
GDX Nerve Fiber Layer Analysis
GDX Nerve Fiber Layer Analysis has been clinically proven to accurately discriminate between healthy and glaucomatous eyes and to be predictive of visual field loss. This analysis provides unique early case detection and is the only glaucoma imaging device with a separate Screening Mode to help identify which patients should receive a full glaucoma examination. This analysis also tracks change over time. This Advanced Serial Analysis feature evaluates subtle changes so you can manage glaucoma with more confidence. The typical exam time ranges from 3 to 5 minutes.
Humphrey Visual Field/ Matrix Visual Field
Definition: The visual field is the total area in which objects can be seen in the peripheral vision while the eye is focused on a central point.
No special preparation is necessary for these tests and there is no discomfort with this test. Some visual field tests take a long time and may be tiring.
You sit in front of a dome and stare at a central target within the dome. A computer-driven program flashes small lights at different locations within the dome's surface, and you press a button when you see the lights in your peripheral vision. Your responses are compared to age-matched controls to determine the presence of defects within the visual field.
The test will detect any loss of peripheral vision and provide a map of that loss which will be helpful in diagnosing the cause.
