摘　　要：目的　探讨视网膜冷凝复位术与组织氧自由基水平的关系。方法　对 2 1例复发性视网膜脱离患者的视网膜下液 (SRF)内丙二醛含量进行测定。结果　复发性视网膜脱离患者的 SRF中丙二醛水平为 1.78± 0 .6 5 mm ol/L ;高于同期原发性视网膜脱离患者的 SRF;二者 SRF丙二醛水平均显著低于自身血清。结论　视网膜冷凝复位术可造成组织周围氧自由基的增加 。Objective To study the levels of malondialdehyde(MDA) in subretinal fluid(SRF) with the recurrent rhegmatogenous retinal detachment.Methods Using colorimetric reaction of thiobarbituric acid(TBA),the MDA were measured in all samples of SRF and serum with the recurrent rhegmatogenous retinal detachment of 21 eyes.Results The level of MDA in SRF with the recurrent rhegmatogenous retinal detachment was 1.78±0.65 mmol/L,higher than in primary SRF and less than in serum.Conclusion The cryotherapy may cause the lipid peroxides on the retina and choroid.
