Since glaucoma is a progressive disease, physicians are constantly searching for reliable tools to monitor it over time. Before the introduction of optical coherence tomography, determination of glaucoma progression relied heavily on clinical assessment of the optic nerve, comparison of disc photos over time and visual field analysis. Although these remain key elements of the glaucoma evaluation, they’re still subjective and qualitative in nature, limiting their ability to detect progression reliably. In this article, we’ll provide tips on how to use the OCT devices we’re familiar with to monitor progression, and how to avoid artifacts and other errors that can lead you astray.

Anatomy and OCT

One major advantage of OCT is its ability to show detailed, quantitative information about the various retinal layers, which corresponds to tissue sections on a histology slide...
