Early Warning Signs
Because most people with glaucoma have no early symptoms or pain, it is important to have regular, routine eye exams so that glaucoma can be diagnosed and treated before long-term visual loss occurs.
Some of the early warning signs include:
- Ocular pain
- Cloudy vision with halos
- Blurry vision
- Red eyeballs
- Small blind spots in the peripheral vision
- Abdominal pain
A clear, watery fluid called the aqueous fluid is a filtrate of blood, which fills the chambers of the eye. This is a source of nourishment because it eliminates waste and cleans the eye. The process of the aqueous fluid flowing in and out creates a pressure that is called the intraocular pressure and the inflow versus the outflow of aqueous fluid is measured. When people have glaucoma, the inflow and outflow of this pressure is not working properly and can be categorized as open angle glaucoma or closed angle glaucoma. With open angle glaucoma, peripheral vision tends to be affected first and if not treated, it can result in a loss of vision.
