[Efficacy of Ultra-wide Angle Fundus Imaging without Dilated Pupils in Annual Health Check-up Examination].

Abstract To evaluate efficacy of ultra-wide angle fundus imaging without mydriasis for health screening. The judgment rate and the detection rate of ocular diseases in 1160 eyes of 580 patients (Optos group) who underwent ophthalmic screening with Optos 200Tx ultra-wide field scanning laser ophthalmoscope without mydriasis from May 2013 to April 2014 were compared with those of 774 eyes of 387 patients who underwent ophthalmic screening with mydriasis (Mydriasis group). The judgment could be made in 1156 eyes (99.7%) in the Optos group except for 4 eyes because of severe cataracts in 3 eyes and a corneal inlay to correct presbyopia in one eye. The judgment could be made in all eyes in the Mydriasis group. Peripheral retinal lesions could be detected in the Optos group including 2 eyes with retinal breaks, but the detection rate of peripheral retinal lesions including chorioretinal atrophy and retinal detachment was significantly higher in the Mydriasis group. Optos wide-angle fundus imaging can detect peripheral retinal lesion even without mydriasis and can be considered useful for health screening because of its convenience.
