人体微量元素中,锌含量占第二位,而眼中锌含量在人体中最高。视网膜脉络膜含400—500ppm;正常房水平均为0.3ppm,(0.359mg/ml);视神经100ppm;角膜和巩膜40—50ppm;晶体30ppm,玻璃体50ppm,虹膜睫状体300ppm。如在24小时内注入剂量的锌分布为:视网膜和脉络膜8%,巩膜3%,肝脏仅为0.5%。锌在前房的清除率为每分钟0.72%,因此,在人体特殊组织中,视网膜脉络膜含锌量最高。锌与眼部组织及眼疾的关系越来越受到重视。
In human trace elements, the zinc content occupies the second place, while the eye zinc content is highest in the human body. Retinal choroid containing 400-500ppm; normal room level 0.3ppm, (0.359mg / ml); optic nerve 100ppm; cornea and sclera 40-50ppm; crystal 30ppm, vitreous 50ppm, iris ciliary body 300ppm. For example, if the dose of zinc is infused within 24 hours: 8% of the retina and choroid, 3% of the sclera and only 0.5% of the liver. Zinc in the anterior chamber clearance rate of 0.72% per minute, therefore, in the body’s special tissues, the highest amount of zinc in the retina choroid. The relationship between zinc and eye tissue and eye diseases is getting more and more attention.
