Clinical applications of anterior segment optical coherence tomography

Anterior segment optical coherence tomography (as-oct) was recently developed and has become a crucial tool in clinical practice. as-oct is a noncontact imaging device that provides the detailed structure of the anterior part of the eyes. in this review,the author will discuss the various clinical applications of as-oct,such as the normal findings,tear meniscus measurement,ocular surface disease (e.g.,pterygium,pinguecula,and scleromalacia),architectural analysis after cataract surgery,post-lasik keratectasia,descemet's membrane detachment,evaluation of corneal graft after keratoplasty,corneal deposits (corneal dystrophies and corneal verticillata),keratitis,anterior segment tumors,and glaucoma evaluation (angle assessment,morphological analysis of the filtering bleb after trabeculectomy,or glaucoma drainage device implantation surgery). the author also presents some interesting cases demonstrated via as-oct. © 2015 su-ho lim.
