Google Picasa图片管理软件在斜视诊断眼位照相中的应用

Application of google picasa software for photography of diagnostic positions of gaze in strabismus

目的探讨Google Picasa图片管理软件在斜视患者诊断眼位照片编辑和管理中的临床应用方法。方法按照9方位和2方位眼位照相的图片面部剪裁范围和拼接方位,对Picasa软件的图片剪裁比例、拼接比例、图片拼接间隙、图片信息格式进行统一设置后,使用该软件对10位斜视患者的9方位和2方位原始照相进行调整、剪裁、拼贴、基本病历信息录入、保存、打印。操作由一位熟练掌握软件使用者和一位初学者分别完成,初学者事先经过10个患者的练习。对比诊断眼位照片拼图的效果,并比较软件初学者与熟练操作者拼图耗时情况。结果使用Picasa软件经过简单三步标准操作,即完成标准的斜视诊断眼位照相的编辑拼图,眼位照相的拼图格式统一,患者信息标注规范并可以进行检索;熟练操作者完成每位患者9方位拼图的平均耗时为69.4 s,2方位拼图的耗时为19.3 s,初学者完成每位患者9方位拼图的平均耗时为86.9 s,2方位拼图的耗时为21.6 s,与熟练操作者拼图耗时无显著性差异(P>0.05)。结论使用Picasa软件对斜视患者诊断眼位照片进行编排、拼贴,简单易行,拼图格式统一规范,效率高且通用性强,经过简单学习即可快速掌握。

Objective To investigate the application of Google Picasa software for the editing and management of photography of diagnostic positions of gaze in strabismus.Methods Picasa software was used to collage the original pictures into 9 positions and 2 positions photography of diagnostic positions of gaze in strabismus patients.Before collaging,the cropping area,cropping dimension,page format and grid spacing were set properly.10 strabismus patients’9 positions and 2 positions photography of diagnostic positions of gaze were collaged using Picasa by a beginner and a skilled user of this software respectively.The effect of collage and the time spent by beginner and a skilled user to finish the collage were compared.Results After three simple steps,a standard collage of diagnostic positions of gaze in strabismus can be edited and accessed.Skilled user of this software spent 69.4 seconds and 19.3 seconds in collaging the 9 positions and 2 positions photography of diagnostic positions respectively,while beginner user spent 86.9 seconds and 21.6 seconds respectively.There was no significant difference between the two groups for the time they spent(P>0.05).Conclusion It is simple and practicable to apply Google Picasa software for the editing and management of photography of diagnostic positions of gaze in strabismus.A standardized collage of photography of diagnostic positions of gaze in strabismus can be easily accessed by a beginner user of Picasa software.
