PURPOSE: To demonstrate the utility of operating on the temporal trabecular meshwork with in vivo - aqueous angiography demonstrating new aqueous outflow channels. METHOD: In a patient with primary open angle glaucoma, nuclear sclerosis, and medically uncontrolled intraocular pressure, Indocyanine green aqueous angiography (0.5%) was performed to visualize baseline functional aqueous outflow channels. This was followed by 30 degrees bent needle ab-interno goniectomy in the temporal quadrant, where no aqueous outflow channels were initially visualized. Aqueous angiography was repeated using 2% fluorescein to visualize aqueous outflow channels after bent needle ab-interno goniectomy. RESULTS: Prebent needle ab-interno goniectomy, aqueous angiography revealed functional outflow channels in the nasal quadrant although none were visible in the temporal quadrant. Postbent needle ab-interno goniectomy in temporal quadrant aqueous angiography demonstrated 2 new aqueous outflow channels. CONCLUSION: In a patient with open angle glaucoma, following temporal quadrant ab-interno goniectomy, the recruitment of aqueous outflow channels was demonstrated using aqueous angiography.
