 Glaucoma usually undiagnosed in general population. People usually ignores the symptoms and came late when disease already get worsened. This study aimed to compare intraocular pressures in general population having inclusion criteria with different types of tonometers and its correlation with central corneal thickness in patients presenting in OPD at Ophthalmology Department of Sir T hospital, Bhavnagar, Gujarat.

In this Hospital based cross-sectional observational study with 9-month duration, 72 patients between the ages of 30–75 years were evaluated, after taking into consideration the inclusion and exclusion criteria. Detailed history taken including chief complaints, past history, family history, personal history followed by general and systemic examination. 72 patients having inclusion exclusion criteria were analyzed with three different tonometers (Goldmann applanation, Non-contact tonometer (NCT), Schiotz tonometer), and the correlation between each other were measured. Then central corneal thickness is measured with OCT Tomography, and the results were compared to intraocular pressure (IOP).

 When compared to the non-contact tonometer, we found that the Schiotz tonometer had the highest correlation. These associations were also seen in people with diabetes and hypertension. Nonetheless, as patients age, there is a corresponding rise in the correlation between the gold standard approach and the tonometer.

 All the tonometer showed significant correlation with the gold standard technique (Goldmann applanation tonometer), over a range of intra ocular pressure, between the ages of 30 -75 years, in diabetics and hypertensive patients, and in the patients with different CCT values.

To compare the diagnostic accuracy of the iCare rebound tonometer and the Goldmann Applanation Tonometer (GAT).Patients and

A comparative assessment of intraocular pressure (IOP) was conducted on patients visiting the vision clinic at Torfeh Eye Hospital, Tehran, Iran, from May 2022 to August 2022. The IOP of both eyes of each patient was initially measured by one individual using the iCare tonometer device. Then, the patients were referred to the ophthalmology department, where the IOP of both eyes was measured using the GAT by an ophthalmologist who was unaware of the IOP results obtained with the iCare tonometer.

The mean age of the patients entering the study was 49 ± 17 years. The mean IOP measured with the GAT was 14.47 ± 5.92 mmHg with a range of 6 mmHg to 75 mmHg. With the iCare tonometer, it was 14.44 ± 6.42 mmHg, with a range of 6.1 mmHg to 80.7 mmHg, indicating no statistically significant difference between the two devices. There was a very strong correlation(r: 0.864; 95% confidence interval 0.732-0.983; P < 0.001) between the measurements by GAT and the iCare device. The correlation strength did not show a substantial difference between male(r: 0.885) and female (r: 0.816) patients. The correlation was strong among patients with low IOP (r: 0.631), normal IOP (r: 0.797), and high IOP (r: 0.781) eyes.

iCare tonometer IOP readings have acceptable correlation with GAT readings and can be considered a reliable alternative to GAT for measuring IOP by primary health providers.

 Military activities cannot be classified as pure isometric or pure dynamic exercise. The effects of these activities on intra ocular pressure (IOP) have not been investigated so far.

 The current study aimed to evaluate the short-term effects of military activities on IOP.

Following a cross-sectional design, this study was conducted on 44 soldiers in the Islamic Republic of Iran Army. Soldiers’ heart rate and IOP were recorded before marching activities at rest, immediately after marching, and 30 minutes after the march. The measurements were repeated in the same process in 3 months. The marching activity was the same for all participants and took 60 minutes.

 In total, 44 soldiers were studied, with a mean age of 21.80 ± 1.56 years. The IOP measurements before, immediately after, and 30 minutes after the marching were significantly different. IOP was significantly lower after the march (P < 0.001), and 30 minutes after the march, it was increasing gradually. The same results were observed in the IOP measurements 3 months later. We found no association between IOP after marching and heart rates before and after marching. Also, no significant association was observed between IOP and age.

 IOP was significantly decreased after marching, but it was transient. The results indicate that the dynamic component in military marches is more prominent than isometric parts.
