The use of ocular imaging tools to estimate structural and functional damage in glaucoma has become a common clinical practice and a substantial focus of vision research. The evolution of the imaging technologies through increased scanning speed, penetration depth, image registration and development of multimodal devices has the potential to detect the pathology more reliably and in earlier stages. This review is focused on new ocular imaging modalities used for glaucoma diagnosis. glaucomatous

The evolution of ophthalmic imaging tools during the past two decades has enabled the acquisition of in-vivo and real time objective, accurate, quantitative, and precise measurements of the ONH, the retinal nerve fiber layer (RNFL), and macular substructures. Currently, glaucoma imaging research and development is mostly focused on imaging tools with higher scanning speeds, higher axial and transverse resolution, the ability to simultaneously estimate both structural and functional characteristics of scanned tissue, new automated algorithms for image registration, segmentation, and analysis, and tools that allow sensitive detection of glaucoma progression. The purpose of this manuscript is to review the progress in ocular imaging development within the past five years and to discuss promising future trends.
