During the calibration of the Goldmann tonometer, the expected movement of the tonometer reading at each stop should be how much?

0.01-0.02g
0.05-0.1g
0.2-0.3g
0.5-1.0g

The correct answer is: 0.05-0.1g

The expected movement of the tonometer reading at each stop during the calibration of the Goldmann tonometer is typically in the range of 0.05 to 0.1 grams. This range is crucial for achieving accurate intraocular pressure measurements, which are essential for diagnosing and monitoring glaucoma and other ocular conditions. This specific range reflects a fine level of sensitivity necessary for the tonometer's operation, allowing for precise adjustments that are vital in clinical settings. A movement outside this range may indicate calibration issues or necessitate adjustments in technique or device setup. In contrast, options that suggest much smaller movements would not provide the necessary precision, while larger movements could lead to overshooting desired pressure levels and potential misinterpretations of the tonometer readings. Such precise calibration is critical to ensure both the reliability of the measurements and the overall effectiveness of patient care in ocular health.
