THE EFFECT OF VITAL DYES FOR POSTERIOR EYE SEGMENT ON THE RABBITS'' ELECTRORETINOGRAM
The aim of the work was to assess the impact of trypan blue vital dyes on electoretinogram (ERG) of rabbits after the experimental vitrectomy. Operations with use of domestic dye (“Optimedservice”, Russia) and MembraneBlue Dual dye (D.O.R.C., Netherlands) were performed on 12 eyes of 6 rabbits. ERG was recorded before and in different terms after the surgery. ERG of pair intact eye was served as control. Vital dyes caused transitional changes of ERG at different terms after surgery. The follow-up showed the reduction of ERG at first days after surgery and the recovery of ERG to 14th day. The further morphological, histochemical studies are necessary to assess the vital dyes retinal toxicity.
