Purpose: To evaluate the efficacy of optical coherence tomography for the analysis of anterior segment after glaucoma surgery.
Design: Interventional case report.
Methods: In a 79-year-old man with primary open-angle glaucoma, optical coherence tomography was performed on the left eye after nonpenetrating deep sclerectomy.
Results: 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.
Conclusion: 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.
