A comparison of four methods of tonometry: method agreement and interobserver variability


PA Tonnu, T Ho, K Sharma, E White, C Bunce … - British Journal of Ophthalmology, 2005 - bjo.bmj.com
Methods: IOP was measured with the Goldmann applanation tonometer (GAT),
Tono-Pen XL, ocular blood flow tonograph (OBF), and Canon TX-10 non-contact
tonometer (NCT) in a randomised order in one eye of each of 105 patients ...

The influence of central corneal thickness and age on intraocular pressure measured by …


PA Tonnu, T Ho, T Newson, A El Sheikh, K … - British Journal of Ophthalmology, 2005 - bjo.bmj.com
Results: A significant association between measured IOP and CCT was found with
each instrument. The change in measured IOP for a 10 μm increase in CCT was
0.28, 0.31, 0.38, and 0.46 for the GAT, Tono-Pen, OBF, and NCT, ...
