Abstract

Background: Glaucoma has been established as the second leading cause of blindness as blindness due to glaucoma is untreatable. Glaucoma screening is very important step to prevent visual loss and for screening intraocular pressure measurement plays an important role.
Aim: The study aims to compare the Goldmann applanation tonometer with Huvitz non-contact tonometer.
Material and Methods: This was a cross-sectional study conducted for a period of 3 months March 2023 to May 2023. 200 patients were included in the study taking care of exclusion criteria. The study was started after getting permission from the institutional ethics committee. Patients were randomly taken and they underwent NCT and GAT. The values of both were compared and analysis was done using STATA and SPSS software.
Findings: The study includes 200 patients who underwent GAT and NCT. The age group ranges from 21-45 years. The IOP values showed that the mean value in the GAT group was 15.54 mmHg and that in the NCT group was 17.255 mmHg. So, the mean value shows that the values obtained from NCT are higher than those obtained from GAT. The mean IOP in the NCT group is 1.715 mmHg higher than that in the GAT group. The study has a p-value of 0.001.
Conclusion: Both the above methods are frequently used for the measurement of IOP. NCT is an easy and less time-consuming method that is used more frequently. But the study concludes that the results of NCT are not as accurate and should be rechecked with those of GAT in cases with borderline values before starting workup of glaucoma.
