DHA Ophthalmologists - FAQ Sample Questions

Check calibration on the Goldmann applanation tonomter by

Correct Answer:

use of a calibration bar
the goldmann applanation tonometer is a device commonly used by ophthalmologists to measure the intraocular pressure (iop) of a patient's eye, which is crucial for diagnosing and managing glaucoma. ensuring that the tonometer is accurately calibrated is essential for obtaining reliable iop measurements. there are several methods to check and adjust the calibration of the goldmann applanation tonometer.

one common method involves the use of a calibration bar. a calibration bar is a precisely machined rod with known dimensions and properties. to use this, the calibration bar is placed in a special holder that can be attached to the tonometer. the purpose of this setup is to simulate a standard pressure on the tonometer tip, thereby allowing the practitioner to verify that the tonometer readings align with the expected values given the known properties of the calibration bar.

the procedure typically involves adjusting the position of the tonometer's tip to touch the calibration bar. the reading on the tonometer should match the predefined pressure value associated with the calibration bar. if discrepancies are observed, adjustments need to be made to the tonometer to bring it into correct calibration. this might involve mechanical adjustments or resetting certain components of the device according to the manufacturer’s guidelines.

another method for checking the calibration involves placing the tonometer’s tip on a test block. like the calibration bar, the test block is designed to present a known resistance and size to mimic the characteristics of a human eye under typical examination conditions. the operator can then check if the tonometer measures this controlled setup accurately.

occasionally, the calibration is verified by measuring the eye of a patient or a model eye where the pressure is already known. this method is less common due to the practical challenges of creating or finding an eye model with a precisely controlled intraocular pressure.

if all methods accessible at the clinic or hospital fail to confirm the calibration or if recalibration is not successful, the tonometer may need to be sent back to the manufacturer. the manufacturer can then perform a more comprehensive recalibration or repair any potential faults that could not be addressed on site.

it is critical for the calibration of the tonometer to be checked regularly and maintained diligently. accurate measurement of intraocular pressure is crucial in the diagnosis and management of glaucoma, a major cause of blindness worldwide. faulty readings due to miscalibration can lead to misdiagnosis or inappropriate treatment, thereby endangering the vision health of patients. thus, the use of calibration bars, test blocks, and periodic checks are essential components of ophthalmic practice.
