The analysis of various extent visual field defect in chronic glaucoma patients

To study the situation for the follow eye visual field defect of patients with severe visual field loss in 1 eye from chronic glaucoma,and to analyze the relative risk factors for visual field defect in such eyes. The visual field defect scores of fellow eyes were calculated in 47 cases [primary chronic angle-closed glaucoma (PACG) 23 cases and primary open angle glaucoma (POAG) 24 cases] with severe visual field loss in 1 eye (visual field defect score > or = 12). The relations were analyzed between the visual field defect scores of fellow eyes and the visual acuity,the maximal and the mean intraocular pressure (IOP), ages, refraction, diagnosis, the last periods of glaucoma, gender and the anti-glaucoma surgery history. Spearman correlation analyse was used to estimated the correlation between the visual field defect scores of fellow eyes and the above factors. In the fellow eyes of the 23 cases PACG, 4 cases showed no visual field defect (score 0),5 cases showed the mild visual field defect (score 1-5), 7
