ABSTRACT

Objective To cpmpare the assessment of retinal and choroidal disease using confocal scanning laser ophthalmoscope (cSLO) imaging and color fundus camera.Methods Sixty-seven patients (90 eyes) with fundus diseases were included in this study.There were 35 males (51 eyes) and 32 female (39 eyes),mean age was 51.32 years.All subjects underwent fundus imaging using cSLO technology and traditional color fundus camera,positive numbers of every retinal pathological change were calculated and compared.Spectral domain-optical coherence tomography (SD-OCT) was also done to compare the accordance rate between two modes of fundus imaging (cSLO technology and traditional color fundus camera) and SD-OCT in choroidal changes.Results The positive numbers of retinal microaneurysm (x2 =4.157,P＜ 0.05) and epiretinal membrane (x2 =5.428,P ＜ 0.05) using cSLO fundus imaging were significantly higher than traditional color fundus camera,while the positive numbers of cotton wool spots (x2 =0.523),retinal hemorrhage (x2 =0.117),hard exudates (x2 =0.325) and macular hole (x2 =0.070)were no significant different (P＞ 0.05).The SD-OCT accordance rate of choroidal pathological changes using cSLO technology was higher than traditional color fundus camera (x2 =9.143,P=0.007).Conclusion In retinal and choroidal diseases,the imaging quality of cSLO fundus imaging technology is better than the traditional color fundus camera technology.
