摘要: Inter-individual differences in corneal properties are ignored existing methods for measuring intraocular pressure IOP, a primary parameter used screening and monitoring of glaucoma. The the stiffness between individuals can be more than double this difference would lead to IOP measurement errors up 10 mmHg. In study, an instrumented partial-contact indentation analysis method that account inter-individual is developed. was tested on 12 porcine eyes ex vivo 7 rabbit vivo, results were compared controlled IOPs determine method's validity. Analyses showed without correction, mmHg error found approach IOP. With method, less 2 founded measured These effectively variations measurement.
