Glaucoma
The eye has an internal fluid (aqueous) which maintains a pressure inside the eye, referred to as the intraocular pressure. If drainage of this fluid is disrupted, the pressure within the eye rises and may result in glaucoma. Glaucoma is a disease process that occurs when the nerves that transmit information from the eyes to the brain become damaged. Although glaucoma is not preventable, early detection is the key to maintaining a good visual outcome.
There are two main types of glaucoma:
Open angle glaucoma where there is a gradual increase in the intraocular pressure and usually no associated symptoms and
Angle closure glaucoma where a sudden rise in pressure causes vision to become blurred. When an angle closure attack occurs, the intraocular pressure increases due to blockage of the aqueous outflow. This build-up of pressure within the eyeball may result in acute onset of severe pain, blurry vision, redness of the eye and colored haloes around lights. The pain is usually quite severe and often not localized but may involve the whole head. This may be accompanied by tearing , nausea and vomiting.
An angle closure glaucoma attack is an ocular emergency requiring immediate medical attention.
Eye Problems may contribute to Headaches and Migraines, so it is important to have them professionally addressed. It is also important to investigate for other potential causes, as many cases of Headaches and Migraines have more than one ingredient.
