Speaker Session Topic
Glaucoma is a degenerative and progressive optic neuropathy that results in irreversible vision loss. More specifically, the disease is characterized by the loss of retinal ganglion cells (RGC) which in turn lead to functional deficits. With the advent of optical coherence tomography (OCT), this glaucomatous structural change (i.e., RGC loss and subsequent retinal nerve fiber layer thinning) could be identified, characterized, and followed throughout stages of the disease. These structural changes are often detected prior to glaucomatous changes manifesting on a functional test such as the visual field. In this way, the OCT has armed clinicians with more objective and quantitative measures to supplement their evaluation. Also with OCT, clinicians can make an earlier diagnosis in glaucoma suspects or potentially detect progression sooner in existing glaucoma patients such that they can adjust treatment sooner than by using standard visual field testing alone. Today, spectral domain-OCT (SD-OCT) offers improved resolution and faster scanning rates. SD-OCT is available on more than one commercial platform/machine. This talk will review the SD-OCT scans that are most useful for glaucoma diagnosis or disease progression on the various available commercial platforms.
