Abstract. Purpose:To report the course of visual acuity and field in patients of normal-tension glaucoma(NTG)and to discuss factors related to progression of visual field defect. Cases and Method:This retrospective study was made on 64 eyes of 64 patients who were diagnosed with NTG and who were followed up for 10 years or longer. The series comprised 37 males and 27 females. The age ranged from 53 to 85 years,average 69 years. Following factors were evaluated:intraocular pressure,refraction,medication score,history of surgery,corneal thickness,family history,visual field measured by Humphrey perimeter,and visual acuity expressed as logMAR. Results:Visual acuity decreased by 2 lines or more in 13 eyes(20%). Impaired central visual field appeared to be the cause in 3 out of the 13 eyes. Visual field could be followed up in 51 eyes. Mean deviation(MD)of the slope averaged -0.14 dB per year. In 19 eyes(37%),it was significantly greater by an average of -0.42 dB. No background factor was identified that was significantly correlated with progression of visual field defect. Conclusion:Follow-up for 10 years or longer has shown no factor related to progression of visual acuity or field in NTG.
