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 (χ2=4.157, P < 0.05) and epiretinal membrane (χ2=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 (χ2=0.523), retinal hemorrhage (χ2=0.117), hard exudates (χ2=0.325) and macular hole (χ2=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 (χ2=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.
ObjectiveTo determine the positive results of confocal scanning laser ophthalmoscope (cSLO) based retinal imaging and traditional color fundus camera in screening epiretinal membrane (ERM) in elderly people. MethodsA total of 184 retired staffs from certain company (363 eyes) were included in this study, 153 were men (304 eyes) and 31 were women (59 eyes). The mean age was 74.35 years (range 47-92 years). All subjects were underwent fundus imaging using cSLO technology and traditional color fundus camera and Cirrus high definition optical coherence tomography (HD-OCT). The imaging quality of two technologies were analyzed and compared according to the evaluation standards. The positive accordance rate was used to compare between two modes fundus imaging (cSLO technology and traditional color fundus camera) and HD-OCT. ResultsIn 363 eyes, the positive number of screening ERM using HD-OCT was 122 eyes (33.6%); the positive number of traditional color fundus camera was 33 eyes (9.1%); the positive number of cSLO imaging was 76 eyes (20.9%). The HD-OCT positive accordance rate of screening ERM using traditional color fundus camera and cSLO technology were 27.0% vs. 62.3%. The HD-OCT positive accordance rate of screening ERM using cSLO technology was significant higher than traditional color fundus camera (χ2=30.81, P < 0.001). ConclusionThe HD-OCT positive accordance rate of screening ERM in elderly people was higher using cSLO technology than using traditional color fundus camera.
