Aim: To compare IOP measurement of Perkin’s tonometer and Schiotz tonometer with respect to Goldmann applanation tonometer (GAT).
Materials and Methods: 100 eyes of 50 patients aged 18 to 65 years presenting to Ophthalmology OPD were selected by randomization and detailed general and ophthalmic examination was done. IOP was measured using applanation tonometers (Perkin’s and GAT) and indentation tonometer (Schiotz tonometer) in that order.
Results: The study population included 38 male eyes and 62 female eyes; 50 right eyes and 50 left eyes. There was a statistically highly significant difference seen for the values between the groups (p<0> There was a statistically non significant difference seen for the values between Perkin’s tonometer and GAT (p>0.05). While there was a statistically highly significant difference seen for the values between GAT and Schiotz tonometer (p<0> There was a statistically non significant difference seen for the IOP values between right eye and left eye. There was a statistically non significant difference seen for the IOP values between males and females.
Conclusion: Measurement of IOP with Perkin’s was closer to the values obtained by GAT. Perkin’s being portable, easy to use and precise tonometer than Schiotz tonometer, can be considered as an excellent substitute to GAT, for large scale examination, if cost is not a concern.
Keywords: Intraocular pressure, Perkin's tonometer, GAT, Schiotz tonometer.
