AIM: To investigate the relationship among the optic topography, optic head blood flow and visual field changes in 24 glaucoma patients (28 eyes) with controlled intraocular pressure after anti-glaucoma surgeries. METHODS: The retinal tomoscan and optic head blood flow of 24 patients were examined by Heidelberg Retina Topography (HRT) and Heidelberg Retina Flowmetry (HRF). The visual field was examined by Ocutopus101 program Normal. All the patients were examined every 2 months and the follow-up was 6 months. RESULTS: During the 6mo of follow-up, there were no significant changes in visual acuity, visual field or optic topographic values in early glaucoma patients, but the optic disc blood flow decreased more than 10% in 3 eyes. There were no changes in central visual acuity of middle or late stage patients, but the mean sensitivity had a tendency to decrease. Moreover, the mean retinal nerve fiber layer thickness became thinner gradually, and optic disc blood values decreased CONCLUSION: Part of early glaucoma patients had an impairment of microcirculation in the optic nerve head during the postoperative follow-up. There were a tendency of visual function, microcirculation of optic nerve head and mean retinal nerve fiber layer thickness to descend in all of middle and late glaucoma patients. LA: Chinese
