Imaging for Glaucoma Detection and Progression

All types of glaucoma involve glaucomatous optic neuropathy. The key to the detection and management of glaucoma is understanding how to examine the optic nerve head (ONH). The rate of structural progression is highly variable with some individuals progressing very slowly over many years, while others exhibit a much more rapidly progressing picture. This talk covers a series of related topics, the characteristics of a normal and a glaucomatous ONH, the strategies by which to measure progression (clinical judgement, event, and trend analysis), and instruments that can assist the clinician in the detection and monitoring of structural progression (ONH photography, optical coherence tomography, and confocal scanning laser ophthalmoscopy). The talk is illustrated with examples of clinical imaging, and suggestions for further reading are given.
