[Study on risk factors for central visual field loss in advanced open angle glaucoma].
53 eyes of 53 advanced open angle glaucoma (stage 5 of Aulhorn-Greve's classification) were studied regarding the risk factors for central visual field loss by the Cox proportional hazards model. The cases of foveal threshold under 20 dB were defined as central visual field loss group (9 eyes), and the cases over 20 dB were defined as no visual field loss group (44 eyes). The following clinical factors were statistically analyzed between the two groups: gender, age, family history of glaucoma, refraction, intraocular pressure, blood pressure, visual field measured by static perimetry, optic disc, retinal nerve fiber layer, treatment, and systemic disease. Foveal threshold, mean deviation, pattern standard deviation, corrected pattern standard deviation, and retinal nerve fiber layer defect showed significant difference between the two groups, and diastolic blood pressure and diastolic blood pressure minus intraocular pressure showed a tendency to be related. From the results obtained, intraocular pressure and these other clinical factors should be considered for the management of advanced open angle glaucoma patients.
