Introduction Optical coherence tomography (OCT) has revolutionized patient care in ophthalmology within the last two decades. Initially conceptualized as a means to visualize the posterior segment, advances in OCT technology now allows enhanced, high-resolution imaging of the anterior segment (AS-OCT). Areas covered In this review, we begin by revisiting very briefly the history of OCT, it's working principles and technical aspects specific for anterior segment imaging. We then provide an overview of diagnostic applications of AS-OCT in corneal diseases with clinical examples on how AS-OCT can be instrumental in the differential diagnosis, treatment monitoring, surgical planning, and prognostication. We proceed by summarizing its use as an adjunctive tool in the management of glaucoma including its complementary function in evaluating the iridocorneal angles and ancillary role in visualizing the internal structures of the bleb and the minimally invasive glaucoma implants. Expert opinion Although AS-OCT currently has a wide range of application areas, future research is expected to focus on improving acquisition speed, penetration, and image resolution further increasing the utility of AS-OCT in the clinic.
