F6H8对兔眼前节组织结构毒性影响的实验研究

目的探讨全氟己基正辛烷(perfluorohexyloctane,F6H8)兔眼前房内存留不同时间对兔眼角膜内皮细胞、前房角、虹膜等组织结构的解剖和功能影响,方法 10只比利时有色兔,均以右眼为实验眼,左眼为对照眼。前房穿刺缓放房水后实验眼前房内注入0．2mlF6H8,对照眼注入0．2ml生理盐水。术后定期行裂隙灯、眼压、角膜厚度测量和角膜内皮镜检查,于术后一定时间气栓法处死兔取眼球行组织学检查。结果实验眼的眼压明显高于对照眼;下方角膜内皮细胞计数减少,角膜水肿、增厚。术后4w时小梁网结构失常,虹膜根部新生血管萌芽,角膜内皮细胞肿大,后表面有巨噬细胞附着;8-12w时,下方角膜内皮细胞空泡变性,部分区域变性崩解坏死;前房角大量巨噬细胞浸润,小梁网结构破坏,虹膜表面灶状巨噬细胞浸润并侵犯虹膜基质,虹膜表面新生血管形成。结论 F6H8前房内填充会造成眼前节组织结构和功能的破坏,F6H8作为硅油的清洗剂使用时,术中应尽量将其清除干净,注意避免其进入前房,尤其在无晶状体眼的患者更应谨慎,以免造成角膜内皮损害和继发性青光眼。     

壳聚糖胶原复合膜在兔角膜基质层间的组织相容性

目的探讨壳聚糖胶原复合膜植入兔角膜基质层的组织相容性,以评价其作为人组织工程角膜修复支架材料的可行性。方法选用8只新西兰白兔,根据角膜基质层间植入膜片材料的不同平均分为A、B两组,A组植入壳聚糖胶原复合膜（实验组）、B组植入壳聚糖膜（对照组）。术后观察并记录术眼球结膜充血、角膜水肿、前房闪辉、角膜新生血管、材料的变化等情况,术后第8周取术眼角膜组织制作病理学切片进行HE染色观察,比较两组材料对角膜组织的不同影响。结果术后8周内,实验组炎症反应轻于对照组,且无角膜新生血管发生,对照组有2例发生角膜新生血管,两组膜片均于术后第2周开始降解,但在相同观察时间点,实验组膜片降解程度小于对照组。HE染色显示实验组膜片周围炎性细胞浸润轻于对照组,膜片降解程度小于对照组,降解物与角膜基质纤维融合。结论壳聚糖胶原复合膜与活体兔角膜基质组织的相容性比壳聚糖膜更优,其作为角膜损伤修复材料具有广阔前景。

FK506缓释系统前房植入抑制兔高危角膜移植术后的免疫排斥反应

目的探讨前房植入FK506药物缓释系统（DDS）对兔高危角膜移植术后免疫排斥反应的抑制作用和FK506房水药物浓度与免疫排斥反应的关系。方法107只新西兰白兔中随机数字法选取73只兔进行角膜新生血管化模型的制作,其中68只兔作为受体成功建立高危角膜移植动物模型,随机数字法分为对照组、空白DDS前房植入组、环孢素A（CsA）DDS前房植入组（含CsA 1mg）、0．1％FK506眼液滴眼组及FK506 DDS前房植入组（含FK5060．5mg）。角膜移植术后观察各组角膜植片排斥发生的时间,移植术后1周取各组实验兔眼房水和静脉血进行FK506药物浓度检测。0．1％FKS06眼液滴眼组和FKS06 DDS前房植入组在移植术后的不同时间点抽取实验兔眼房水和静脉血,进行FK506药物浓度的检测。观察各组兔移植术后4周和观察期结束时角膜植片的病理变化,同时应用原位杂交的方法检测各组角膜植片内白细胞介素2受体a（IL-2Bot）、单核细胞趋化蛋白1（MCP-1）、Fas及FasL mRNA的表达。结果FK506 DDS前房植入组角膜植片存活时间超过180d,明显优于其他各组（F=926．37,P=0．0000）,其房水和角膜组织中的FK506药物浓度明显高于FKS06眼液滴眼组（T=21．00,P=0．0022）。FKS06 DDS前房植入组在术后24周内均能在房水中检测出FK506。术后4周对照组和空白DDS前房植入组有大量的炎性细胞浸润,并有明显的IL．2Bet和MCP-1mRNA的表达,而CsADDS前房植入组、FK506眼液滴眼组及FK506 DDS植入组角膜未见明显的炎性细胞浸润,未见IL-2Pux和MCP-1mRNA的表达。各组均未见明显的Fas和FasL mRNA的表达。结论前房植入FK506 DDS可有效地抑制高危角膜移植术后免疫排斥反应的发生,房水中较高的FK506药物浓度是防治术后发生免疫排斥反应的重要因素。

Experimental Study on the Effect of Perfiuorodecalin on Rabbit Corneas

Purpose: To study the effects of perfluorodecalin on the cornea of the rabbit eyes. Methods: Perfluorodecalin (0.05 ml/each) was injected into the anterior chambers of eighteen rabbit eyes. Corneal morphology and endothelial cells were monitored clinically by slit-lamp biomicroscope and specular microscope for 26 weeks. Animals were sacrificed in 1st, 2nd, 4th, 10th, 16th, 22nd, and 26th week after injection, respectively,and the corneas were examined under the light microscope. Results: Perfluorodecalin droplets looking like "fish eggs" were found at about 1/4 ～1/2 of the corneal height in the inferior anterior chamber. Corneal opacification on the area contacted with perfluorodecalin was observed in five eyes five weeks after injection,and all in the 22nd week. Mutton fat KPs in one eye were seen in the 6th week firstly, and in all eyes in the 7th week. Corneal pannus formation in one eye was present in the 4th week, two eyes in the 5th week and three eyes in the 6th week. Retrocomeal fibrous membrane in one eye was detected at the 6th week and 3 eyes at the 7th week respectively.After injection of perfluorodecalin, endothelial cell density was sighificantly decreased (2789 + 192 vs. 2 341 +658, P ＜ 0.01) and corneal thickness was increased. Conclusions: Perfluorodecalin injected into anterior chamber can lead to corneal damage and inflammatory reaction. Eye Sciemce 2001; 17:16 ～ 20.

The effect of povidone iodine on the corneal endothelium

PURPOSE: Povidone iodine has been proven to be a valuable antiseptic solution in preparing the eye for surgery and is an alternative to postoperative topical antibiotics. No study has addressed the intraocular toxicity of povidone iodine after injection into the anterior chamber. We investigated the potential toxicity of povidone iodine on the corneal endothelium after injections into the anterior chamber in a rabbit model. METHODS: In this study we used 24 eyes of 12 albino rabbits. The eyes were divided into the following three groups according to the drugs tested: group A, 5% povidone iodine; group B, 10% povidone iodine; group C, balanced salt solution. The injected eyes were evaluated by biomicroscopy, specular microscopy, corneal pachymetry, and transmission and scanning electron microscopy. RESULTS: Corneal edema was observed in all eyes of groups A and B. In groups A and C, the endothelial cell morphology was not significantly changed and the mean endothelial cell count of the eyes did not change significantly (p = 0.5054). There was no significant difference in corneal thickness between groups A and C (p = 0.3823), but there was a significant difference between groups B and C ( = 0.0002). Transmission and scanning electron microscopy results were normal in group C but not in groups A and B. CONCLUSION: Povidone iodine in both 5% and 10% concentrations demonstrates severe toxicity when one drop of either concentration is placed directly in the anterior chamber. When povidone iodine is used in preparing the eye for intraocular surgery and as an alternative to postoperative antibiotics, the inadvertent leakage of povidone iodine into the anterior chamber must definitely be prevented.     

利用后弹力层撕除术建立兔眼角膜内皮失代偿模型的评估

目的利用后弹力层撕除术建立一种新的角膜内皮失代偿模型以便更好地了解该手术的组织反应。方法根据手术方法的不同将40只新西兰成年兔平均分为4组：角膜内皮刮除组、后弹力层撕除组、后弹力层撕除角膜内皮移植术（DSEK）组及DSEK供体组;右眼为手术眼。每组定期通过角膜内皮活体染色,眼前节照相和UBM至少观察2个月。结果后弹力层撕除组角膜始终保持混浊,角膜内皮刮除组和DSEK组角膜逐渐透明,角膜厚度逐渐降低。活体染色显示角膜后弹力层撕除组术后2个月仍无角膜内皮生长。结论后弹力层撕除术建立的角膜内皮失代偿模型显示了后弹力层撕除后角膜内皮愈合过程,可用于角膜内皮移植的研究。     

Corneal endothelial proliferation in anterior synechiae: experimental and clinico-histopathological studies

Corneal endothelial proliferation over the iris was studied on experimental anterior synechiae in rabbits up to 6 months. Clinico-pathologic studies of 102 post-keratoplasty eyes revealed that only 4 out of 51 anterior synechiae were endothelialized. In contrast all 10 leukomatous+ adhesions found in a series of 132 eyes removed after perforating corneal trauma were endothelialized. The above studies suggest that the most important factor for endothelial proliferation is the availability of suitable substrate. The rate of growth depends on growth factors present in anterior chamber.     

角膜交联对真菌性角膜溃疡的治疗作用

背景 真菌性角膜溃疡是一种严重威胁视力的炎症性疾病,严重者需行角膜移植术或眼球摘除术.角膜交联术（CXL）是近年来治疗一些角膜疾病的有效方法,但其用于真菌性角膜溃疡的疗效方面少有研究.目的 观察CXL对真菌性角膜溃疡的治疗作用和效果.方法 选取8周龄健康新西兰白兔15只,其中5只作为正常对照组,另取10只兔刮除右侧角膜上皮行角膜划痕,涂抹镰刀菌液,然后行异种脱细胞角膜片覆盖,制备真菌性角膜溃疡动物模型.按照随机数字表法将模型兔随机分为非治疗组和CXL治疗组,每日行裂隙灯显微镜检查,测量角膜病灶的直径,并观察角膜水肿和炎性细胞浸润情况.于CXL治疗后第3、7、14、21、28天分别对非治疗组和CXL治疗组兔眼行眼前节照相和激光扫描共焦显微镜检查.治疗后4周,收集15只实验兔角膜组织,于扫描电子显微镜下检测正常对照组、非治疗组和CXL治疗组角膜胶原纤维的超微结构.结果 实验兔右眼造模后3d即可见角膜病灶区灰白色溃疡灶,激光扫描共焦显微镜下浅基质层局部见豆荚样菌丝.造模后l周角膜溃疡灶加深,范围扩大,激光扫描共焦显微镜下浅基质层见大量真菌孢子和短棒样菌丝,可见角膜内皮细胞层有炎性细胞及前房内渗出.CXL治疗后3、7、14、21 d,CXL治疗组兔角膜上皮缺失范围均小于非治疗组,差异均有统计学意义（P＜0.05）.治疗后28 d,正常对照组、非治疗组和CXL治疗组兔角膜胶原纤维束平均直径分别为（24.6±1.8）、（24.9±1.9）和（43.0±7.4）nm,3个组间差异有统计学意义（F=27.05,P=0.00）,其中CXL治疗组胶原纤维直径较非治疗组和正常对照组增粗,差异均有统计学意义（t =-5.30、5.40,P＜0.05）,胶原纤维间见较多成纤维细胞;而非治疗组兔角膜胶原纤维直径与正常对照组间差异无统计学意义（t=0.25,P＞0.05）,正常对照组胶原纤维间少见成纤?     

The effect of scleral buckling surgery on corneal astigmatism, corneal thickness, and anterior chamber depth

PURPOSE: To evaluate the effect of scleral buckling surgery on corneal topography, corneal thickness, and anterior chamber depth. METHODS: Thirty-two eyes of 32 patients who underwent encircling buckling surgery for rhegmatogenous retinal detachment were included in the study. Fellow eyes comprised the control group. Orbscan II topography system was used to determine the changes in corneal topography, corneal thickness, and anterior chamber depth before surgery and 1 week, 1 month, and 3 months after surgery. Statistical analyses used in the study were independent t test, paired t test, one way analysis of variance, and correlation analyses. RESULTS: Postoperatively, mean central corneal astigmatism at 1 week, 1 month, and 3 months was 4.3 +/- 2.0 diopters (D), 3.3 +/- 1.6 D, and 3.1 +/- 1.0 D, respectively. The change between 1 week and 3 months was statistically significant. Central cornea was thickened at the first postoperative week. The thickness gradually decreased to the preoperative levels at 3 months. Anterior chamber depth decreased, and the anterior chamber remained shallow after the surgery. The comparison between preoperative (2.94 +/- 0.6 mm) and postoperative anterior chamber depth was statistically significant at 1 week (2.57 +/- 0.7 mm), 1 month (2.83 +/- 0.7 mm), and 3 months (2.73 +/- 0.6 mm). CONCLUSIONS: Corneal changes after scleral buckling surgery were mild to moderate and the cornea almost resumed its preoperative parameters in 3 months' time. However, the anterior chamber remained shallow during 3 months of follow-up.
