Background: An accurate assessment of Intraocular pressure (IOP) is vital in establishingdiagnosis of Glaucoma and decision making regarding various treatment modalities available. Thepurpose of this study is to compare Goldmann Applanation Tonometer (GAT) with Air pufftonometer. Methods: Cross-sectional comparative study conducted. 73 eyes from 73 patients wereincluded in this study and intraocular pressure (IOP) was measured by GAT and PT100 at SheikhKhalifa Bin Zayed Hospital, Muzaffarabad, Benazir Shaheed Teaching Hospital, Abbottabad.Results: Mean age of the patients was 53.17±13.80 years. Mean IOP measurements showedsignificant differences in measurements performed by the two tonometers (p<0.05). Correlationrevealed significant relation between PT100 and GAT (Pearson’s correlation 0.715, p<0.01).Conclusions: Compared to non-contact air-puff tonometer, the Goldmann applanation tonometeris a reliable and consistent technique for measurement of intraocular pressure.Keywords: Glaucoma, Intraocular pressure, Goldmann applanation tonometry, Non-contact airpuff tonometer
