What is the true intraocular pressure?

Research output: Contribution to journalConference articlepeer-review


Glaucoma is an ocular disease characterized by an abnormally high intraocular pressure (IOP), by a reduction in visual field, or both, that if untreated may result to blindness. A comparative pilot clinical study was performed in 113 patients that underwent surgery for various causes to determine the accuracy of the Goldman applanation tonometer in measuring IOP. The investigation shows the intraoperative IOP monitor instrument is difficult to use under topical anesthesia, making further refinement mandatory. A multivariate statistical analysis of the data collected on the patients is required to better discern the limitation of applanation and indentation tonometry and justify the use of more accurate, but invasive techniques.
