PURPOSE: To compare intraocular pressure (IOP) measured by Goldmann applanation and ICare rebound tonometers in eyes with glaucoma or ocular hypertension. Objects and Method: This prospective study was made on 44 eyes of 32 patients with glaucoma or ocular hypertension. All had IOP readings of 21 mmHg or higher by ICare tonometer. The series comprised 14 males and 18 females. The ages ranged from 18 to 73, average 54 years. RESULTS: IOP readings averaged 25.2 mmHg by Goldmann tonometer (x) and 25.7 mmHg by ICare tonometer (y). There was no significant difference between the two methods. Simple linear regression analysis showed a linear equation of y = 0.8541x+4.1747. The difference between the two readings, or y-x, was 0.41 ± 2.30 mmHg (mean ± standard deviation). It was within ± 3 mmHg in 38 eyes (86%). CONCLUSION: ICare tonometer promises to be of value in screening eyes for glaucoma or ocular hypertension as substitute for Goldmann tonometer.
