Outcomes of the Icare Rebound Tonometer versus the Gold Standard Tonometer in Measuring Intraocular Pressure among Mzuzu University Students, Malawi

IntroductionThe Goldmann Applanation Tonometer (GAT) is accepted as the gold standard tool to measure Intraocular Pressure (IOP). Besides, there an emerging Icare Rebound (RBT) which can be alternative in terms of measuring IOP.ObjectiveThis research aimed analyze agreement, and repeatability intraocular pressure (IOP) measurements compare outcomes RBT GAT among Mzuzu University Students Malawi.MethodsFor this cross-sectional study, 107 participants aged 18 29 years underwent ophthalmic examination with three IOP taken by two examiners using GAT. ResultsThe were found have a strong correlation (r=0.809, p>0.001), intra-class 0.787 (p>0.001). The mean difference measured machines was 1.99±1.05mmHg, statistically significant. However, according Bland-Altman analysis, no agreement between results given machines, bias -1.979 (CI -2.28, -1.68, p > 0.001). In repeatability, better than RBT, CR 7.512 10.418 respectively.ConclusionThe offer comparable measures. Therefore, recommended for community outreach programs where cannot employed.
