Role of anterior segment optical coherence tomography in angle-closure disease: a review.

This article aims to review the published literature pertaining to the use of anterior segment optical coherence tomography (AS-OCT) in the evaluation of angle-closure disease. Searches on the available published literature were last conducted on 15 June 2017. Rated as Level I evidence, we found that AS-OCT has shown good sensitivity and moderate diagnostic accuracy to detect narrow angles when compared with gonioscopy. AS-OCT quantitative and qualitative parameters demonstrated strong association with the presence of gonioscopically closed angles. This technology provides an objective non-contact method of assessing the angle that is well tolerated by the patient and correlates well with the information provided by gonioscopy.
