Update: diagnostic concepts in open-angle glaucoma

New advances aided by computerized technology have been made in the detection and quantification of glaucomatous psychophysical and optic-nerve abnormalities. The aim of all these techniques is earlier detection of intraocular pressure-related damage to the optic nerve. In addition, improvements in the sensitivity and specificity of diagnostic modalities offer the possibility to better quantitate and therefore monitor the dynamics of the glaucomatous process. These devices offer great potential for pathophysiologic investigations. However, expanded research needs to be performed prior to the clinical application of the techniques discussed in this review. The future looks promising for improved methods in the diagnosis and management of glaucoma.
