What is the key function of a sphygmomanometer in optometry?

To measure blood glucose levels
To assess blood pressure
To perform visual acuity tests
To analyze pupil response

The correct answer is: To assess blood pressure

The core function of a sphygmomanometer in optometry is to assess blood pressure. Monitoring blood pressure is vital in eye care as various systemic conditions, such as hypertension, can have significant effects on ocular health. Elevated blood pressure can lead to complications such as hypertensive retinopathy, which can impact vision. Therefore, using a sphygmomanometer helps optometrists understand the patient's overall health and make informed decisions regarding their eye care and treatment plans. The other options are specific to different diagnostic tools and processes that do not pertain to the function of a sphygmomanometer. Blood glucose levels are measured using a glucometer, visual acuity tests are conducted with vision charts or optotypes, and pupil response analysis typically involves the use of a pupillometer or simple observation of reflexes, none of which are the role of a sphygmomanometer.
