Abstract: 【Abstract】 Objective To evaluate the clinical value of the rebounder tonometer (RBT) in congenital glaucoma by comparing with Perkins applanation tonometer and Schiotz tomometer. Design Evaluation of diagnostic techniques. Participants 29 cases (29 eyes) of the congenital glaucoma patients aged 12.0 ± 3.0 months who were measured intraocular pressure (IOP) in Beijing Tongren Eye Center. Method IOP was measured with the rebound tonometer, Schiotz tonometer and Perkins applanation tonometer. Measurements  were repeated three times each tonometer. Main Outcome Measures IOP values and Pearson correlation coefficient. Results Mean IOP values obtained by RBT, Schiotz and Perkins tonometer were 19.3±8.5 mm Hg, 21.1±10.8 mm Hg, and 18.5±7.8 mm Hg, respectively(F=0.61, P=0.55). The difference of IOP values among three tonometers was not significant. The average difference between RBT and Perkins tonometer was 0.8±2.4 mm Hg. The average difference between Schiotz and Perkins tonometer was 2.6±2.4 mm Hg. The average difference between Schiotz and RBT was （1.8±2.4）mm Hg. The values of Perkins applanation tonometer were significant correlated with RBT （r=0.934，P=0.000） and Schiotz（r=0.933，P=0.000）. Conclusion The accuracy of rebounder tonometer can meet the IOP measurement needs in congenital glaucoma patients. (Ophthalmol CHN, 2012, 21: 278-281)
