Purpose: To assess the most accurate and practical technique for intraocular pressure (IOP) measurement in children and adolescents Type of the Study: Cross-sectional observational Methods: 90 eyes of 45 patients were included in this study. Central corneal thickness (CCT) was measured using specular microscopy. IOP was assessed by Goldman applanation tonometer (GAT), Non-contact tonometry (Air-puff), and Tono-Pen in both right and left eyes. Results: The mean age of participants was 14.8 years. Mean CCT was 548.7 mm in the right eye and 549.2 mm in the left eye (P=0.687). Mean IOP measured by GAT, Air-puff, and Tono-Pen was 11.7, 14.1, and 11.3mmHg in the right eye, respectively, and 11.7, 14.2, and 11.5mmHg in the left eye, respectively. Air-puff readings were significantly higher than GAT and Tono-Pen (P>0.0001) in both the right and the left eyes. On the other hand, Tono-Pen showed no statistically significant difference from GAT measurements either in the right (P=0.447) or the left eye (P=1). The highest correlation with GAT was seen with the Air-puff. CCT was positively correlated with all used devices. Conclusion: Tono-Pen provides the most accurate alternative for GAT. Although Air-puff offers a more accessible option for IOP measurement in adolescents, attention should be taken as it gives significantly higher measurements. [ABSTRACT FROM AUTHOR] |
