Abstract

Confocal scanning laser tomography is an imaging technique used for determining the topography of the optic nerve head and retina. Since images can be acquired through undilated pupils and analysed rapidly, the technique is particularly suited for clinical use. One of the largest potentials of scanning laser tomography is the detection of structural alterations in the optic nerve head and peripapillary retina caused by glaucoma. The ability to detect change depends on obtaining an accurate estimate of test-retest variability of regional measurements due to instrumental, computational and a host of physiological factors.
