Purpose To assess the utility in clinical practice of anterior segment optical coherence tomography (OCT) in glaucoma surgery. Methods Consecutive cases review of patients diagnosed of primary open angle glaucoma, closure angle glaucoma, pseudoexfoliative glaucoma. Anterior segment 5 Line Raster OCT protocol (Cirrus HD –Spectral Domain Technology) was performed to evaluate the follow‐up of glaucoma surgeries (trabeculectomy and drainage devices) of these patients. Results Anterior segment OCT achieved a correct display of the angle anatomy after surgery. About glaucoma surgery images, it showed a correct display of structures in superficial sclera. However, it showed limitations at the evaluation of structures in deep sclera: space under sclera flap and exact location of the trabecular drainage. Conclusion Anterior segment OCT is a tool of in vivo diagnostic, that achieves an objective anterior segment evaluation in glaucomatous eyes after surgery. This device shows limitations at the evaluation of deep sclera. However, anterior segment OCT provides clinical information about glaucoma post‐surgical anatomy and its functionality.
