A case of secondary glaucoma studied by optical coherence tomography of the anterior ocular segment

摘要

PURPOSE: To compare slit lamp biomicroscopy or gonioscopy with optical coherence tomography (OCT) and to assess the efficacy of OCT in a case of anterior segment disease. CASE: A 74-year-old male who had bilateral keratoconus. The left eye was aphakic, and a penetrating keratoplasty was performed on it, as well as Nd:YAG laser capsulotomy. The prognosis was good in the early postoperative stage. But 6 months postoperatively, we could not control the intraocular pressure and judged that a second operation might be needed. Before the operation, we tried to get images of the anterior segment of this eye using slit lamp biomicroscopy, gonioscopy, and OCT. RESULTS: Findings obtained by OCT were more useful than those obtained by slit lamp biomicroscopy or gonioscopy to determine the method of operation. DISCUSSION: This case substantiates the view that observation of the anterior ocular segment by OCT is useful for such cases, because in cases of corneal disease we can not get much information about the deep and endothelial side of the cornea from slit lamp biomicroscopy.
