  • Experimental research of intraocular retention of domestic perfluorocarbon liquid

    Objective To investigate the effect of long-term intraocular retention of domestic perfluorocarbon liquid (PFCL) on morphology and histology of ocular tissues. Methods A total of 18 New-Zealand rabbits were randomly divided into 3 experimental groups, whose left eyes underwent intraocular injection with 0.3, 0.6, and 1.0 ml PFCL, respectively. All of the right eyes of the rabbits were in the control group. The morphological, electrophysiological and histological changes of the ocular tissue were observed 4, 8, and 12 weeks after the injection. Results No clinically significant retinopathy but only mild morphological changes were found in group 1 and 2, while obvious morphological and histological changes were found in group 3. Mild morphological and histological changes were found in all of the rabbits 4-8 weeks after the injection while significant ones were found 8-12 weeks after the injection. The results of electroretinography indicated a statistically significant decline of amplitude of b wave in group 3. Conclusions Long-term intraocular retention of few PFCL may cause mild histological changes but not affect the clinical function. Plentiful PFCL remains in eyes may lead to toxic reaction to the ocular tissue. (Chin J Ocul Fundus Dis, 2006, 22: 128-130)

  • 国产全氟乙烷在玻璃体视网膜手术中使用浓度的探讨

    目的 探讨国产全氟乙烷(C2F6)在玻璃体视网膜手术中使用的适宜浓度。 方法 对我院施行玻璃体视网膜手术的80例连续病例的80只眼,术中随机分别选用16%和20%的 C2F6作为眼内填充气体注入眼内,对术后的眼压变化、气泡消失天数和视网膜复位情况进行比较。 结果 20%C2F6组术后眼压增高情况和气泡在眼内的消失天数明显高于16%C2F6组。视网膜复位情况两组无显著差异。 结论 CC2F6眼内注入的合适浓度为16%。 (中华眼底病杂志,1998,14:204-205)
