Step-by-Step Guide to Manual Pupil

Diameter Measurement

 To perform a manual measurement, the patient and examiner should be properly positioned, with the patient's eyes at the same level as the examiner's. Illuminate the pupil with a penlight, taking care not to shine the light directly into the patient's eye.

 Use a ruler or pupil gauge to estimate the diameter, typically in millimeters. Be quick and accurate in your observations, as the pupil constricts in response to light, potentially altering its size.

Tips for Accurate Pupil Diameter

Measurement

 Consistency is crucial for accuracy in pupil diameter measurement. Maintain steady lighting conditions to minimize artificial constriction or dilation of the pupils. Keep the patient's focus steady, minimizing distractions that might influence pupil size.

 Practice repeated measurements to account for natural fluctuations and enhance reliability. With attention to these details, you can refine your technique and enhance the accuracy of your findings.
