ABSTRACT
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.

Spontaneous resolution of a detachment of Descemet's membrane following phacoemulsification. Optical coherence tomography (OCT) images at 1 day after cataract surgery (a) demonstrated superior planar type DMD with diffuse corneal edema. OCT images at postoperative 1 week (b) and 2 weeks (c) revealed spontaneous resolution of DMD without descemetopexy.

Mentions: Descemet's membrane detachment (DMD) is considered a severe complication after intraocular surgery and trauma [34, 35]. Some DMDs, however, reattach spontaneously with a good prognosis, and a few corneas do not clear in spite of surgical treatment [31]. AS-OCT can demonstrate different statuses of the DMD, including planar/nonplanar, local/extensive detachment, and rupture [34–36]. AS-OCT is also a valuable tool for selecting the appropriate treatment and for monitoring the treatment outcomes when corneal edema is present [35] (Figure 7).
