Abstract

Purposes: To correlate the intraocular pressure readings obtained by Schiotz Tonometer and Goldmann Applanation Tonometer (GAT).

To find the degree of agreement between both tonometers.

Methods: 300 eyes of 150 glaucoma suspects and diseased subjects were selected from various age groups. Their IOP was assessed using Schiotz tonometer and GAT and the readings were compared.

Results: Average age of the patients was 54.96 years. There was a positive linear correlation between Schiotz and GAT established for both eyes, which was statistically significant. RE showed better agreement as per agreement graph.

Conclusion: Schiotz tonometer showed significant correlation with the Gold standard technique (GAT) over a wide range of age groups. Hence, Schiotz tonometer is a reliable screening tool that can be used in community outreach ophthalmology services in a developing country like India.
