They say that the eye is the window to the soul, but it is also very much the window to the body. An ophthalmology exam can show you far more than just the health of your eyes, even to the point of saving your life. Read on to learn more about how optometrists can diagnose brain tumors through a routine eye exam.
The Optic Nerve and The Brain
The optic nerve is a group of more than 1 million nerve endings that carry visual information from the retina to the brain. During an eye exam, your optometrist can actually see the head of the optic nerve, making it the only part of the central nervous system that is visible.
How Optic Nerves Respond to Brain Trauma
Our brains constantly produce and reabsorb fluids, maintaining just enough intracranial pressure to protect themselves from head trauma. When the brain has a tumor or other disease, it causes the optic nerve to swell. Therefore, a swollen optic nerve can indicate a potential brain issue. In some cases, the head of the optic nerve will also be pale-colored because a tumor or large mass is pressing against it.
Other Brain Tumor Symptoms in the Eyes
The optic nerve isn’t the only eye-related indicator of a brain tumor. Blurry or unfocused vision, “ghost images” or double vision, sudden changes in pupil size, and rapid changes to the retina can also be symptoms. Brain tumors are also usually accompanied by other symptoms, like headaches and nausea. These are often ignored because they are interpreted as something less serious, like the flu.
Diagnose Medical Issues Early With an Eye Exam
The retina, or the tissue in the back of the eye, is the only place where doctors can look at small blood vessels and nerves in your body without needing to make an incision. This means that having an annual routine eye examination with one of our Raleigh optometrists incredibly useful to diagnosing other physical issues. Many common medical conditions such as diabetes, high blood pressure, and high cholesterol can be first detected within the eye, often before any symptoms start to show themselves.
