Studies on Scleral Pneumatonometry

Study	Correlation	Mean Difference	Equation
Kuo et al.	r: 0.94	9.0 mmHg compared to corneal IOP	Corneal IOP = 1.04 × Scleral IOP – 10.37
Lin et al. ⁴	--	13.2 mmHg compared to assigned IOP^*	Assigned IOP = 1.01 × Scleral IOP – 14.14
Kapamajian et al. ⁵	r: 0.57	8.08 mmHg compared to corneal IOP	Corneal IOP = 0.32 × Scleral IOP – 0.05 × Age + 11.90

assigned IOP > corneal IOP by 3.78
