Glaucoma is a condition of the eye that can damage the optic nerve of an individual. Please note that the optic nerve is responsible for supplying visual information from the human brain from the eyes.
The condition is known to worsen with time. It is connected to a buildup of pressure inside the eye. Over time, the pressure may heighten and ultimately erode the optic nerve tissue, resulting in vision loss.
A high number of people with the condition don’t experience any early symptoms or pain. However, there are a few signs that may be noticed by individuals with this condition.
If any of the symptoms are noticed early, it is advisable to seek immediate treatment. Fortunately, people who catch the symptoms early stand a chance of not having an additional vision loss.
Here are the symptoms and signs of glaucoma:
One of the early signs of glaucoma is nausea  that individuals experience. Nausea is painless, but it is incredibly discomforting for individuals that experience it. In simple terms, nausea is the urge to vomit. Generally, it is acute and short-lived, even for people with glaucoma. However, when the condition is prolonged, it can be quite severe.
Aside from glaucoma, nausea may occur for a wide range of other reasons. Examples are motion from a car or plane. It may also be due to intake of certain pills on an empty stomach or consuming a small amount of food. If you experience nausea, please see a licensed doctor immediately for diagnosis.
