目的 :测定眼铁质沉着症房水中铁离子含量 ,探讨其对手术预后及相关影响。方法 :对 1 7只铁质沉着症眼 ,在摘取眼内异物手术前 ,取 0 2ml房水标本 ,对照组取 1 0只正常尸体眼房水 ,采用铁试剂盒 ,亚铁嗪法测定铁离子含量。结果 :1 7例房水铁离子含量平均为 2 989μg/ml。对照组平均含量为 0 63 1 μg/ml。术后视力 0 5以上者 4例 ,0 1～ 0 4者 4例 ,0 0 1～ 0 0 9者 2例 ,手动以下者 7例 ,其中眼球萎缩 3例。结论 :眼铁质沉着症房水铁离子含量明显高于对照组 ,其对眼组织的损伤与铁离子含量有直接关系 ,同时与异物的化学成分、大小、位置与有无包裹以及异物在眼内存留的时间等因素有关。
Objective: To determine the content of iron ion in aqueous humor of octopus and to explore its effect on the prognosis of surgery. Methods: Twenty-seven cases of iron-induced eye disease were selected. Before removal of intraocular foreign body material, 0 2 ml aqueous humor samples were taken. In the control group, 10 normal cadaveric aqueous humor eyes were obtained. Iron ion content. Results: The average iron ion content in 17 cases of aqueous humor was 2 989 μg / ml. The average content of the control group was 0 63 1 μg / ml. Postoperative visual acuity more than 0 4 in 4 cases, 0 1 ~ 0 4 in 4 cases, 0 0 1 ~ 0 0 9 in 2 cases, the following manual in 7 cases, of which 3 cases of atrophy. CONCLUSION: The iron content in aqueous humor is significantly higher than that in the control group. The damage to eye tissue is directly related to the content of iron ions. At the same time, the chemical composition, size, location and presence of foreign matter, Memory retention time and other factors.
