Comparison of the screening efficiency of epiretinal membrane using confocal scanning laser ophthalmoscope imaging and color fundus camera in elderly people

Abstract

Objective To 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. Methods A 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. Results In 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). Conclusion The HD-OCT positive accordance rate of screening ERM in elderly people was higher using cSLO technology than using traditional color fundus camera.
