[Effect of intraocular irrigating solution on electroretinogram during pars plana vitrectomy].
The effects of intraocular irrigating solutions on the human retina are not known. We recorded 30 Hz-flicker electroretinograms (ERGs) during vitrectomy, and examined the effects of perfusate S-MA2 and DE-057 on the human ERG. The amplitude of the 30 Hz-flicker ERGs were not significantly different for the two irrigating solutions. The peak latency of the 30 Hz-flicker ERG was increased 14 +/- 4.4% (mean +/- SE) during irrigation with S-MA2, compared with the preoperative peak latency. Replacement of S-MA2 by DE-057 increased the peak latency by 37 +/- 5.8% (p < 0.01). Since the peak latency of the 30 Hz-flicker ERG became shorter after replacement of DE-057 by S-MA2, these effects were reversible (p < 0.01).
