Study Notes
Eye Pressure
- The clear fluids in the eye ball, namely aqueous and vitreous humors, transmit light to the retina and maintain the eye ball in a fixed size and shape.
- Normal eye pressure helps to maintain good vision, with only a 0.1 mm change in diameter.
Importance of Eye Pressure
- Partial blockage of the drain system can increase eye pressure, restricting blood supply to the retina and affecting vision.
- This condition is called glaucoma, which can lead to:
Effects of Glaucoma
- Moderate vision loss
- Severe vision loss, including tunnel vision and blindness
Measuring Eye Pressure
- Physicians can estimate eye pressure by feeling the eye with their fingertips.
- Eye pressure can be measured using a tonometer.
- Normal eye pressure ranges from 12-23 mm.Hg.
