A comprehensive review of diagnostic imaging technologies to evaluate the retina and the optic disk.

Ophthalmic imaging has undergone a revolution over the past 20 years with increasingly efficient and high-definition modalities now available. The use of wide-field retinal angiography, fundus autofluorescence, state-of-the-art spectral domain, and enhanced depth imaging optical coherence tomography has proven to be effective in this field. This comprehensive review is devoted to retinal and optic disk imaging modalities and their clinical implications. It is based on the published literature in the field of ophthalmic imaging with a focus on recent advances. Ophthalmic imaging plays a crucial role in the management of patients with both isolated retinal disease and systemic diseases with ocular manifestations. Evolving technology enables imaging of ocular disease in vivo, facilitating objective assessment of disease progression and response to treatment. These latest technical improvements in ophthalmic imaging are now a part of standard ophthalmic assessment in academic centers and most private practices. In the coming years, further advances may improve diagnostic sensitivity and enable cost-effective screening of large populations.
