Comparison of bleb morphology between trabeculectomy and deep sclerectomy using a clinical grading scale and anterior segment optical coherence tomography.

Significant differences in bleb morphology, correlating with improved IOP outcomes in TRAB eyes compared with DS eyes in patients with open-angle glaucoma, were showed by both the IBAGS and AS-OCT. Despite the limitations of each classification system, a higher bleb with an increased aqueous reservoir is associated with optimal IOP results.
