Since loss of vision is usually the first sign of glaucoma, it's important to be diagnosed in the early stages. hypertension (1 in 3 adults), and only half of them are able to manage it. The non-contact computerized tonometer, also known as the air puff test, is the applanation tonometer that uses air for IOP measurement and is extremely common for screening patients in comprehensive eye examinations. It is important to understand that changes in eye pressure do not cause any pain, and may therefore go unnoticed for years while causing gradual vision loss. high blood pressure health center/high blood pressure a-z list/related resources /how do you check blood pressure with fingers article.
