  • Comparison between the intraocular pressure values measured by Goldmann tonometer and Tono-pen tonometer in patients undergone vitrectomy

    ObjectiveTo compare the results of intraocular pressure (IOP) values measured by Goldmann tonometer with which measured by Tono-pen tonometer, and to evaluate the feasibility of Tono-pen tonometer.MethodsA total of 120 patients were selected, including 60 who had undergone simple pars plana vitrectomy (PPV) and the other 60 who had undergone PPV with silicon filling. IOP of all of the patients was measured by Goldmann tonometer or Tono-pen tonometer 3 days after the operation, and the results of the two measurements were compared.ResultsThe mean IOP was (19.72±4.62) mm Hgin the patients measured by Goldmann tonometer and (19.69±4.60) mm Hg in patients measured by Tono-pen tonometer. There was no statistic difference of results between the two measurements (P>0.05). High correlation between the results of the two methods when the IOP was at 8 to 29 mm Hg was found. ConclusionsTono-pen tonometer is a simple method to measure the IOP of patients who have undergone PPV or PPV with silicon filling when their IOP is at 8 to 29 mm Hg.(Chin J Ocul Fundus Dis, 2005,21:303-305)
