Is it uncomfortable to undergo intraocular pressure examination during physical examination

Eye pressure examination usually does not cause significant discomfort, but some sensitive individuals may experience temporary eye pressure. Eye pressure examination is an important means of screening for eye diseases such as glaucoma, and non-contact tonometers or Goldmann flattening tonometers are commonly used in clinical practice.

Non contact tonometer measures intraocular pressure by lightly touching the cornea with airflow. During the process, a gentle airflow is felt blowing towards the eyes, and most people only experience a slight blink reflex without obvious pain. Before the examination, it is necessary to follow the doctor's instructions and keep your eyes wide open while keeping a watchful eye. The entire process takes about 1-2 seconds to complete. The Goldmann flattening tonometer requires the application of anesthetic eye drops on the corneal surface, followed by a gentle touch of the eye with a conical probe. This may result in a slight foreign body sensation, but the pain is not significant under anesthesia. After the examination, there may be a brief blurred vision, which can be restored on its own within 30 minutes. A very small number of patients with corneal sensitivity or dry eye syndrome may experience mild irritation symptoms such as stinging and tearing after examination, usually relieved within 1 hour. If excessive tension during examination leads to eyelid spasms, it may affect measurement accuracy and requires relaxation before retesting. Contact lenses should be removed in advance to avoid discomfort caused by lens displacement during examination.

Avoid rubbing your eyes or using eye makeup before the examination, and cooperate with the doctor to keep your head fixed. Do not rub your eyes within 2 hours after the examination. If you experience persistent redness or pain, please seek timely follow-up. Regular intraocular pressure examination can help detect abnormal intraocular pressure early, and it is recommended to have it checked once a year for people over 40 years old.
