Abstract: The appearance and functionality of blebs are typically assessed based on subjective clinical evaluations, which consider the presence of subconjunctival microcysts, bleb height and width, and conjunctival vascularization.The morphology of blebs, a crucial indicator of both bleb function and complications, can be described and categorized using various clinical grading systems based on slit-lamp examination.4 However, these grading systems lack the ability to visualize the internal structure of the bleb.Ultrasound biomicroscopy (UBM) provides high-resolution imaging, enabling precise measurement of bleb thickness and visualization beneath the scleral flap.5 IntroductIon Since 1960, trabeculectomy has been the standard surgical procedure for treating glaucoma.1 The formation of a filtering bleb, an artificial channel that facilitates the drainage of aqueous humor into the subconjunctival region, is critical for the success and efficacy of trabeculectomy.Adequate aqueous outflow to the bleb and its subsequent absorption are essential for controlling intraocular pressure (IOP) following the surgery. 2 Mitomycin C (MMC) is commonly used during the procedure to modulate wound healing and improve surgical outcomes.
