Blocked or Restricted Drainage in the Eye
In the human eye, a part is filled with a clear fluid that is regularly produced. For consistent eye pressure, there is an equal degree of drainage that occurs. This system takes place through a mechanism called the drainage angle.
When there is a blocked or restricted drainage in the eye, fluids can’t drain out of it. This condition causes an increase in the internal eye pressure, which damages the optic nerve, causing glaucoma.
