病毒性角膜内皮炎的诊治探讨 总被引:3,自引:2,他引:1
病毒性角膜内皮炎并不少见,但因对其临床表现认识不足,误诊、漏诊病例屡见不鲜.角膜内皮炎常由单纯疱疹病毒、带状疱疹病毒感染所致.临床分为三种类型:盘状角膜内皮炎、弥漫性角膜内皮炎和线状角膜内皮炎.临床表现为病变部位角膜水肿,水肿部位羊脂状KP,当合并小梁网炎时伴有眼压升高,临床上常与青光眼-睫状体炎综合征相混淆.治疗关键点是抗病毒和抗炎,正确合理地使用抗病毒药和皮质类固醇激素类药物非常重要.用药的方法分为全身用药和局部用药.大部分患者眼局部用药是主要的给药途径,对于部分反复发作和病情严重的患者可考虑全身给药.皮质类固醇激素应用的浓度和频度要根据患者的病情而定,但基本原则是在足量应用全身和局部抗病毒药的基础上选择生物利用率高的皮质类固醇激素,将炎症迅速控制后逐渐减量,缓慢停药. 相似文献

AbstractPurpose: To evaluate the relationship between corneal hysteresis (CH) and corneal resistance factor (CRF) with age, central corneal thickness (CCT), corneal curvature (KM), corneal volume (CV), and refractive error in naïve eyes. Methods: 105 healthy subjects (58 male and 47 female) were included in this study. The ages ranged from 19 to 82 years (mean 43.1?±?15.4 years) and refraction between ?11?D and +6?D (mean ?0.79?±?2.95?D). CH and CRF obtained with the Ocular Response Analyzer (ORA) were correlated with age, refractive error, Goldmann Applanation Tonometry (GAT), and with CCT, KM, CV obtained with the Pentacam, and with Corneal-Compensated Intraocular Pressure (IOPcc) and Goldmann-correlated intraocular pressure measurement (IOPg) obtained with ORA. A multivariable mixed effect model was used to evaluate associations among these parameters. Results: CH ranged from 6.9 to 14.6?mmHg (mean 10.26?±?1.49?mmHg); CRF ranged from 5.8 to 17?mmHg (mean 10.38?±?1.64?mmHg). Multivariate analysis showed a statistically significant correlation between CH with CCT (p?<?0.001), and KM (p?<?0.001), and between CRF with CCT (p?<?0.001) and GAT (p?<?0.001). Conclusions: Our findings support the hypothesis that CH and CRF are related to the corneal shape and thickness, and show a decrease of CH with age. 相似文献

PURPOSE: To report a case of congenital corneal anesthesia (CCA) associated with hypopyon and tactile hypoesthesia. METHODS: Case report. RESULTS: A 3-year-old girl presented with redness and mild photophobia in the left eye accompanied by corneal ulcer, hypopyon, and corneal neovascularization. Corneal sensation was reduced bilaterally. She exhibited an absence of normal response to painful stimuli. She also had extensive ulceration of the lateral borders and tip of the tongue. The left corneal biopsy revealed negative cultures for bacteria and fungi. She was treated with human amniotic membrane transplantation in the left eye. The response to treatment was good. CONCLUSION: This is the first case of CCA reported in China. CCA is often misdiagnosed as infectious keratitis. Amniotic membrane transplantation is effective in repairing the severe corneal ulcer which may be associated with CCA. 相似文献

Recent studies have shown that alterations in corneal biomechanical properties are associated with corneal pathologies, particularly corneal ectasia. Moreover, these alterations may have implications with regard to the outcomes of therapeutic modalities and corneal refractive surgeries. We address corneal anatomy and its relevance to corneal biomechanical characteristics, as well as ocular and systemic conditions associated with changes in corneal biomechanics. 相似文献

AIM:To assess the safety and cosmetic efficacy of a new multiple noncontinuous transepithelial puncture technique for tattooing a decompensated cornea.METHODS:It was anon-comparative clinical case series study.The study examines 33 eyes in 33 patients with total corneal opacity due to corneal decompensation, which developed following intraocular surgery.Corneal tattooing was performed using the multiple noncontinuous transepithelial puncture technique (i.e. pointage). The safety of this new surgical strategy was assessed by occurrence of adverse events for the follow-up period. The cosmetic efficacy was determined by the patient’s cosmetic satisfaction and independent observer’s opinion about patient appearance.RESULTS:Seven women and 26 men were included in the study. The mean age was 46.4±17.5y (range:7-67). In total, 30 of 33 patients (91%) reported cosmetic satisfaction within the follow-up period. Only 3 patients (9%) required additional tattooing due to cosmetic unsatisfaction. Cosmetic outcomes were analyzed and classified as excellent or good in 13 (39%) and 17 (52%) patients, respectively. No serious adverse events developed, except delayed epithelial healing in 3 cases.CONCLUSION:The cosmetic outcomes of the multiple noncontinuous transepithelial puncture technique for corneal tattooing were good. The safety of this method is higher than conventional procedures. This new procedure also provides improved cost-effectiveness and safety over current corneal tattooing techniques. 相似文献

PurposeTo present the clinical features of four cases with bilateral anterior amorphous corneal opacity.MethodsA retrospective study in four patients with bilateral anterior amorphous corneal opacity was conducted. Examinations included visual acuity, keratometry, slit-lamp biomicroscopy, confocal microscopy, anterior segment optical coherence topography, and histology.ResultsThree female and one male patients (mean age, 52.3 ± 8.9 years) showed bilaterally oval, amorphous sheetlike corneal opacities with central depression and thinning. Superior limbal opacities were observed in two of these patients. The best-corrected visual acuity ranged from 20/50 to 20/400, and the mean of the keratometry was 39.81 ± 3.97 D (diopters). They had mild dry eyes. The anterior segment optical coherence topography demonstrated hyporeflective abnormalities in the anterior depressed stroma in these four patients. Confocal microscopy revealed large round cells at the epithelial layer in one patient, and amorphous opacities with some strand-shaped opacities in the anterior stroma in all four patients. The mean of the corneal endothelial cells density in the eight eyes was 1521 ± 402 cells/mm2. Central corneal stromalysis occurred in three patients, and descemetocele developed in two eyes. One patient received penetrating keratoplasty and two underwent lamellar keratoplasty. The histology of the corneal specimen revealed edematous basal epithelial cells, focal collagen disorganization in the thin stroma, and wartlike excrescences in a thickened Descemet's membrane.ConclusionAnterior amorphous corneal opacity is a rare keratopathy and may be one kind of rare corneal degeneration or dystrophy. Corneal stromalysis may occur in hyporefrective amorphous opacities and progress to descemetocele. 相似文献

目的了解过夜配戴角膜矫形镜(OK镜)后早期角膜曲率、角膜厚度及屈光度的变化.方法14个中低度近视患者(平均屈光度-3.89±1.26D)25眼,随机分成2组分别配戴Dk值不同的角膜矫形镜BE角膜矫形镜组(7人12眼,Dk≈140);E&E角膜矫形镜组(7人13眼,Dk=58).采用夜戴方式,平均配戴时间10.76±1.27小时.用Orbscan角膜地形图系统检查配戴1晚后角膜曲率、角膜厚度的改变.同时记录裸眼视力及屈光度的改变.结果配戴1晚后所有患者的中央及周边的角膜均增厚(P<0.05).Orbscan角膜地形图SimK值在垂直轴及水平轴均变平(垂直轴△SimK0.94±0.56D,P<0.001;水平轴△SimK0.996=0.68D,P<0.001).裸眼视力平均提高0.4±0.24(P<0.001).屈光度平均减少-1.85±0.82D(P<0.001).Dk值不同的2组之间中央及颞上方位点角膜增厚程度的差别有统计学意义.结论过夜配戴角膜矫形镜后减低近视屈光度的效果明显.初次过夜配戴角膜矫形镜可导致角膜厚度轻度增加. 相似文献

目的:研究由全飞秒激光SMILE手术所得的角膜基质透镜作为角膜移植材料治疗角膜溃疡的临床疗效。
方法:回顾性病例研究。收集本院2017-01/06角膜溃疡患者6例6眼,其中细菌性、真菌性、深层异物伴感染各1例1眼,角膜穿孔3例3眼。采用由全飞秒激光SMILE手术所得的角膜基质透镜作为角膜移植的材料进行修复手术,确保植片与角膜层间无空气间隙。术后随访1~6(平均3.71±1.56)mo,观察手术前后视力、角膜移植物存活情况及术后并发症发生情况等。
结果:所有患者均在控制感染下顺利完成手术,无术中并发症。术后所有角膜植片透明。末次随访时,患者最佳矫正视力(best corrected visual acuity,BCVA)较术前明显改善(0.48±0.12 vs 1.50±0.08),差异具有统计学意义(P<0.01)。
结论:来源于全飞秒激光屈光手术的角膜基质透镜用于角膜溃疡修复是安全有效的,但植片的远期疗效尚需进一步观察。 相似文献
