Optical coherence tomographic findings of the anterior segment after nonpenetrating deep sclerectomy.

Abstract

To evaluate the efficacy of optical coherence tomography for the analysis of anterior segment after glaucoma surgery. Interventional case report. In a 79-year-old man with primary open-angle glaucoma, optical coherence tomography was performed on the left eye after nonpenetrating deep sclerectomy. Optical coherence tomography showed thinning of the conjunctiva over the filtering bleb, presence of a space under the scleral flap that is considered as a lake, and presence of fibrous tissue in the bleb. This case indicates that optical coherence tomography, a noninvasive, noncontact optical imaging modality, may be useful for analysis of the anterior segment after glaucoma surgery.
