Abstract:
We assessed the accuracy of Goldmann or Schi-(phi)tz tonometric readings in the gas filled vitrectomized eyes. We performed pars plana vitrectomy with or without lensectomy in 8 rabbit eyes, and in 6 enucleated porcine eyes. Fluid-air exchange was done at the end of the procedure. Intraocular pressure was measured using Goldmann tonometer and Schi-(phi)tz tonometer and was compared with true pressure which was monitored by manometer with indwelling catheter in the intravitreal cavity. Goldmann and Schi-(phi)tz tonometry always showed lower presure value than manometeric one(P<0.05) and the discrepancy was greater at higher range of intraocular pressure. Between these two methods Goldmann tonometry was more accurate in the rabbit eye (P>0.05).
