应用原子吸收法测定了急性视力降低（实验组）和正常人（对照组）各３０例枕发中锌（Ｚｎ）、铁（Ｆｅ）、铜（Ｃｕ）、钙（Ｃａ）、镁（Ｍｇ）、镉（Ｃｄ）含量的变化。结果表明：实验组Ｚｎ、Ｆｅ、Ｃａ、Ｍｇ含量明显低于对照组，差异非常显著（Ｐ＜０．０１）；而Ｃｄ含量明显高于对照组，差异非常显著（Ｐ＜０．０１）；实验组Ｃｕ含量虽然低于对照组，但无显著性差异（Ｐ＞０．０５），而Ｃｕ／Ｚｎ比值明显高于对照组，差异显著（Ｐ＜０．０５）。说明视力降低与体内Ｚｎ、Ｆｅ、Ｃｕ、Ｃａ、Ｍｇ含量降低有关
The contents of zinc, iron, copper, calcium and magnesium in 30 cases of acute ocular degeneration (experimental group) and normal people (control group) were measured by atomic absorption spectrometry. , Cadmium (Cd) content changes. The results showed that the contents of Zn, Fe, Ca and Mg in the experimental group were significantly lower than those in the control group (P <0.01), while the contents of Cd in the experimental group were significantly higher than those in the control group (P <0.01). Although the content of Cu in the experimental group was lower than that in the control group, there was no significant difference (P> 0.05). The Cu / Zn ratio in the experimental group was significantly higher than that in the control group (P <0.05). Description of visual acuity and body Zn, Fe, Cu, Ca, Mg content decreased
