Comparison Of Choroidal Filling and Optic Nerve Head Perfusion Pattern in Glaucoma Patients with Healthy Controls

Glaucoma is a primary cause of irreversible blindness worldwide, it kills the vision silently, having financial burden on society regarding therapy expenses and loss valuable hours day. Objective: To compare choroidal filling time grade status pattern optic nerve head (ONH) perfusion by fundus fluorescein angiography (FFA) in glaucoma patients Methods: Patients with various types were enrolled compared them healthy volunteers no history findings glaucoma. Perfusion using FFA was studied analyzed corresponding visual fields (VF) optical coherence tomography (OCT) Results: There 70 participants study, including 48 22 controls. Choroidal (CFT) 9-12, 13-17, 15-22, 20-33 seconds individuals ocular hypertension (OH), open-angle (POAG), normal-tension (NTG), respectively. In OH, inferonasal inferotemporal hypofluorescence ONH noted, whereas POAG showed an inferonasal, patchy, undefined hypofluorescence. contrast that uniform fluorescence, NTG CFT significantly delayed (p<0.05). We found strong correlation between FFA, OCT, VF defects Conclusions: The prolonged glaucoma, especially cases reveals form areas multiple characteristic patterns POAG, NTG, OH.
