Abstract

Purpose: To study how the non contact tonometer faired against the gold standard - Goldmann applanation tonometer for measuring the intraocular pressure, and to assess if the non contact tonometer was reliable as a mass screening tool for glaucoma detection.Method: Patients in age group of 40 to 60 years coming to OPD were subjected to two method of tonometry: applanation tonometer and non contact tonometer on both eyes, after obtaining the informed consents from them. Three recording were obtained with each method and arithmetic mean of all three reading taken as an intraocular pressure. The data were statistically analyzed using (appropriate test of significance using SPSS software version16.0) Results: The statistical parameter used to analyze the data and the correlation of the study tonometer to the gold standard was the pearson correlation. In this study, the non contact tonometer on the right eyes, compared favorably with the Goldmann applanation tonometer as evidenced by pearson correlation with value of 0.921, with p 0.001 being highly significant. Similarly, on the left eyes of the subjects, tonometers was also highly comparable with a p value of 0.001. Readings of non contact tonometry were almost perfect agreement with the Goldmann applanation tonometer. Conclusion: The current study shows that the non contact tonometer compares favorably with the Goldmann applanation tonometer showing excellent agreement with it. The non contact tonometer can be used as a reliable screening tool in general population.
