Imaging and Navigation Imaging Technologies for the Diagnosis of Glaucoma

In this article we describe recent advances in imaging technologies that quantify the topography of the optic nerve head and retinal nerve fibre layer and their role in diagnosing glaucoma. These technologies include optical coherence tomography (OCT), scanning laser polarimetry (SLP, GDx) and confocal scanning laser ophthalmoscopy (CSLO, HRT). A review of recently published literature was carried out. The diagnostic performance of the different imaging devices is comparable and appears to be acceptable for the diagnosis of manifest glaucoma. The benefits of recent technological improvements need to be fully assessed. At the moment it is not clear which of the currently used imaging technologies is the most useful for diagnosis and management of glaucoma.
