Abstract:
To evaluate the effectiveness of applying visual electrophysiological examination, including flash visual evoked potentials ( FVEP ) , flash electroretinogram ( FERG ) , pattrn electroretinogram ( PERG ) , fundus photography, eye B-type ultrasound, optical coherence tomography ( OCT ) , on visual function assessment and retinal disease detection before cataract surgery. METHODS: Visual elctrophysiological examination, fundus photography, eye B-type ultrasound and OCT were applied in 148 cases ( 196 eyes ) . The positive rate was analyzed according to the results of FVEP, FERG ( or PERG ) , fundus photography, eye B - type ultrasound and OCT.RESULTS: ln 148 cases ( 196 eyes ) , vitreous opacities was showed in 165 eyes ( 84. 2%) by eye B - type ultrasound examination, 31 eyes (15. 8%) without access to B-type ultrasound image; success for fundus camera images in 161 eyes (80. 6%), and unable to get image in 35 eyes (19. 4%); the VEP and ERG in 58 eyes (29. 6%) were get valuable, and the VEP and ERG were saw no obvious abnormal in 138 eyes ( 70. 4%); success for OCT image in 167 eyes (85. 2%), without access to OCT image in 29 eyes (14. 8%). CONCLUSlON: Visual elctrophysiological detection, fundus photography, eye B-type ultrasound and OCT can predict the preoperative visual acuity of cataractous patients. A variety of inspection methods complement each other, can further improve detection rate of retinal diseases and other eye disease before cataract surgery.
