【摘要】 用高效液相色谱测量20例网脱患者网膜下液及静脉血清中视黄醇含量,结果表明:网脱患者血清视黄醇含量为23.36ng/ml±4.16ng/ml,与正常人平均含量(19.59±1.29ng/ml)相比无显著差异(P>0.05);网膜下液视黄醇含量明显低于血清含量,约为血清含量的1/4～1/5。视黄醇含量变化与网膜裂孔大小,网脱范围及PVR 形成有关,与病程无关。视网膜色素上皮变性很可能是网膜格子样变性甚致引起网脱的重要原因之一。更多还原

【Abstract】 Retinol contents in the subretinal fluids from the retinal detachment patients wereanalized by using HPLC analizer and compared with some clinical signs of the patients.The results were as follows:1) there was no significant difference between the retinolcontent in the serum from retinal detachment patients and normal population (23.36ng/ml±4.16ng/ml to 19.59±1.29ng/ml, P>0.05);2) the retinol content in the subretinal fluidwas 1/5—1/4 of that in the patients’ serum (4.58ng/ml),and the variations of the retinolcontent was associated with the sizes of the retinal holes,extents of the retinal detach-ment and PVR formation,but not with duration of the diseases;3) the results suggestedthat the degeneration of retinal pigment epithelial cells may be one of the major cause(?)for the lattice degeneration of the retina and even for the retinal detachment.更多还原
