Tonography helps you to determine –
Correct Answer: The facility of outflow of aqueous
Description: There are two similar terms.
Tonography
Tonography is a non-invasive technique for determining the facility of aqueous outflow (C-value).
Facility of aqueous outflow is estimated by placing schiotz tonometer on the eye for 4 minutes.
Beside tonography, other methods to measure the facility of aqueous outflow (C-value) are perfusion method and suction cup method.
The average C-value is 0.28 ± 0.05 1/ min / mmHg. Most glaucoma patients have C-value less than 0.17.
Tonometery
Tonometry is the assessment of the intraocular pressure of the eye.
Therefore, it is used in the diagnosis of glaucoma and for monitoring the treatment response in glaucoma.
