title: [Imagings of glaucoma: characteristics of ocular configurations and automated diagnosis].
abstract: Glaucoma is characterized by the coexistence of structural changes in the fundus and the corresponding functional abnormalities. The advances in imaging devices that reveal structural changes in glaucoma should facilitate reliable diagnosis of early or preperimetric glaucoma and a proper evaluation of glaucoma progression. Moreover, the increase in our knowledge of structural changes in glaucoma will provide a better platform for investigating up to now unknown glaucoma etiologies. In this review, we summarize a series of our clinical investigations of glaucoma imaging technologies. The diagnostic performance of Heidelberg Retina Tomograph (HRT) II and the characteristics of the HRT II parameters in high myopia were studied with population-based data to provide data for nerve head configuration; the correlation of parameters determined by planimetry of optic disc stereophotography with the results of the HRT II was evaluated; optic disc parameters were determined based on spectral-domain optical coherence tomography (SD-OCT); and optic disc configurations were evaluated in eyes with peripapillary atrophy and eyes with superior segmental optic nerve hypoplasia. Peripapillary retinal nerve fiber layer (RNFL) thickness was determined with SD-OCT in normal Japanese eyes; and the diagnostic performance of RNFL thickness was studied. The characteristics of each layer, including retinal nerve fiber layer, ganglion cell layer, and each complex layer in the macular area, and their correlation with the stages of glaucoma were evaluated. Finally, imaging of the anterior chamber angle using ultrasound biomicroscopy (UBM) were studied about the distribution of the UBM parameters in a Japanese population and the factors relating to the presence of peripheral anterior synechia in narrow angle eyes.
