Imaging in Glaucoma

Optical coherence tomography (OCT) has become a widely used method for assessment of structural damage in glaucoma. The technology can provide quantitative and reproducible measurements of the peripapillary retinal nerve fiber layer (RNFL), Bruch's membrane opening rim width, and macular ganglion cell layer (GCL), which have been shown to be helpful in the diagnosis and assessment of disease progression. Also, the advent of anterior segment imaging devices has allowed for an objective quantitative method of analyzing the iridocorneal angle in glaucoma: anterior segment OCT (AS-OCT) and ultrasound biomicroscopy (UBM). The goal of Research Topic is to shed light on the progress made in recent decades in the field of glaucoma imaging and on its future challenges to provide a complete overview of the field.

The scope of this Research Topic is to provide a collection of original and review articles that will encompass many areas of imaging in glaucoma including:
- anterior segment imaging in glaucoma,
- artifacts of imaging in glaucoma,
- AS-OCT, challenges of imaging in glaucoma,
- new technologies of imaging in glaucoma,
- OCT angiography (OCT-A),
- spectral-domain OCT (SD-OCT),
- swept-source OCT (SS-OCT),
- structural diagnosis of glaucoma,
- structural progression of glaucoma,
- surrogate endpoints in glaucoma,
- UBM,
- use of deep learning in glaucoma imaging,
- use of machine learning in glaucoma imaging.
