Tonometry measures the pressure in the eyes for the detection of glaucoma. Glaucoma is an eye disease that arises from fluid build-up within the eye and damage to the optic nerve. In most cases of glaucoma, the fluid that normally bathes and nourishes the eye drains too slowly, causing a pressure build-up. If untreated, the pressure can eventually damage the optic nerve resulting in a loss of vision. As these changes within the eye are often painless, they can persist for years undetected.
The air-puff non-contact tonometer generally requires no anaesthetic eye drop and is widely used in eye clinics and screening facilities. It is safe due to the “no touch” approach. The process is done with the patient seated with the chin resting on the device and the operator activates the air puff mechanism while aligning the focus to the patient’s eye through the tonometer monitor.
Risk factors contributing to glaucoma:
• Ageing (above 40 years old)
• Family history of glaucoma
• High degree of short-sightedness (myopia) and long sightedness (hyperopia)
• High pressure within the eye ball
• History of steroid use
• History of significant trauma to the eye
• Elderly (angle closure glaucoma)
• Diabetes mellitus
