Daytona超广角眼底成像系统在屈光手术术前检查中的应用

The application of the Daytona ultra-widefield retinal imaging device in preoperative fundus examination before refractive surgery

目的:评价Daytona超广角眼底成像系统对屈光手术术前眼底病变的检查效果。。方法:连续检查拟接受屈光手术的患者312例624眼,分别在自然瞳孔下行Daytona超广角眼底成像系统检查和散瞳后裂隙灯下前置镜结合三面镜检查,比较两种方法检查用时和检出的病变类型和检出率。结果:Daytona超广角眼底成像系统检查的平均时间5.38±1.25min,裂隙灯前置镜检查平均时间7.25±3.23min,差异有统计学意义(P<0.01)。Daytona检出有眼底病变的69例107眼,检出率17.1%,检出病变126处;前置镜结合三面镜检出70例108眼,检出率17.3%,检出病变129处。两种方法检出率的一致性差异无统计学意义(P=1.000)。结论:Daytona具有免散瞳、非接触、检查快捷、超广角等优点,用于眼底病变的检查,效果可靠,可以提升诊疗效率。

AIM: To evaluate the effectiveness of the Daytona ultraw idefield retinal im aging device in preoperative fundus exam ination before refractive surgery. METHODS: A consecutive series of 624 eyes in 312 patients intended to perform ing refractive surgery w ith m yopia w ere exam ined fundus by the Daytona ultraw idefield retinal im aging device before dilating pupil.After dilating pupil,the non-contact slit lam p lenses and three-m irror contact lens w ere used to exam ine fundus again.RESULTS: Average examination time of the Daytona and non-contact slit lamp lenses was 5.38±1. 25 min and 7.25 ± 3. 23 min respectively, there was no statistical significant difference( P < 0. 001). The Daytona detected peripheral retinal pathology in 107 eyes( 17.1%) and the non-contact slit lamp lenses detected peripheral retinal pathology in 108 eyes( 17.3%),126 lesions were detected and there was no statistical significant difference between the two methods( P=1.000).CONCLUSION: The Daytona has non-contact,shorter time and ultra-widefield view of the retina which is a reliable method in examining the retinal pathology without mydriasis.
