The relation of fluorescein angiography in low tension glaucoma with retinal nerve fiber layer defect and visual field damage

The fluorescein angiography, visual field and retinal nerve fiber layer defects (RNFLD) in 23 patients (35 eyes) with low tension glaucoma (LTG) showed that there was a marked positional correspondency between the fluorescein filling defect of the optic disc and the RNFLD (91.4%) or the visual field defect (77.1%). Besides, the rate of positional correspondent between the RNFLD and visual field defect was 80.0%. The study indicated that RNFLD and visual field defect of LTG are related to ischemia of the optic disc.
