Purpose: To compare the precision and accuracy of intraocular pressure (IOP) measurements obtained by Icare PRO and Perkins tonometer in eyes with paediatric glaucoma.
Methods:106 eyes with paediatric glaucoma with clear corneas were included. Two IOP measurements were taken using Icare PRO followed by Perkins tonometer.
Results: The median age of children was 2 years. The median Icare PRO IOP and Perkins IOP was 15.5 mm Hg and 14 mm Hg respectively. Icare PRO IOP was higher than the Perkins IOP by an average of 2.0 mm Hg. The 95% LoA ranged between -5.4 and 9.4 mm Hg. For Icare PRO IOP of less than 19 mm Hg, Icare PRO IOP overestimated Perkins IOP by 1.3 mm Hg. The 95% LoA ranged between -3.0 mm Hg to 5.7 mm Hg.
Conclusion: Icare PRO overestimated the IOP compared to Perkins tonometer. However, for IOP 19 mm Hg, the Icare PRO readings agreed better with the Perkins readings. When Icare PRO IOP ≥ 19 mm Hg, it needs to be reassessed with a Perkins tonometer.
