Precision of intraocular pressure measurements are assessed for using ocular response analyser, Auto Kerato Refracto Tonometer and Goldmann applanation tonometer in healthy eyes. According to the reports, the measurement of intraocular pressure is performed with the help of ORA components.
Glaucoma is the second leading cause of blindness worldwide. Quigley and Broman (2006) estimated that by 2020, 1,618,718 individuals in the Middle East would have glaucoma; the corresponding estimate for 2020 is 2,295,407 individuals. The intraocular pressure (IOP) measurement is vital for monitoring the effectiveness of treatment and evaluating the risk of glaucoma progression. Since IOP reduction is the objective of treatment, accurate IOP assessment is essential for monitoring the efficacy of therapy and for assessing the risk of glaucomatous progression.
