The authors compute a diagnostic (Di) and a prognostic (Pi) index in primary open angle glaucoma. Four groups of patients were studied. Group A consisted of subjects under 50 years of age, group B of subjects over 50 years of age, group C of patients with normal tension glaucoma and group D with high tension glaucoma. All patients underwent color doppler imaging of the ophthalmic, posterior ciliary and choroid arteries. The Di of the choroid vessels were 0.967 +/- 0.011 (gp. A), 1.112 +/- 0.010 (gp. B), 1.506 +/- 0.008 (gp. C) and 2.891 +/- 0.083 (gp. D). The Pi of the posterior ciliary arteries were 22.700 +/- 1.160 (gp. A), 20.000 +/- 0.943 (gp. B), 15.100 +/- 0.568 (gp. C) and 12.100 +/- 0.083 (gp. D). Confirmation of these data might validate them as a tool for preventing the evolution of glaucomatous optic neuropathy.
作者计算了原发性开角型青光眼的诊断指数（Di）和预后指数（Pi）。研究了四组患者。A组由50岁以下的受试者组成，B组由50岁以上的受试者组成，C组为正常眼压性青光眼患者，D组为高眼压性青光眼患者。所有患者均接受了眼动脉、睫状后动脉和脉络膜动脉的彩色多普勒成像检查。脉络膜血管的Di分别为0.967±0.011（A组）、1.112±0.010（B组）、1.506±0.008（C组）和2.891±0.083（D组）。睫状后动脉的Pi分别为22.700±1.160（A组）、20.000±0.943（B组）、15.100±0.568（C组）和12.100±0.083（D组）。这些数据的证实可能会使它们成为预防青光眼性视神经病变进展的一种工具。
