Stress can affect the eyes in a number of ways, including by increasing cortisol levels. Cortisol is a hormone that is released by the adrenal glands in response to stress. It helps the body to cope with stress by mobilizing energy and suppressing the immune system. However, high levels of cortisol can also have negative effects on the body, including on the eyes.
One way that cortisol can affect the eyes is by increasing inflammation. Inflammation is a natural response to injury or infection, but chronic inflammation can damage tissues and organs. Cortisol can increase inflammation in the eyes by stimulating the production of inflammatory chemicals. This can lead to a number of eye problems, including dry eye, conjunctivitis, and blepharitis.
Cortisol can also affect the blood vessels in the eyes. It can cause the blood vessels to constrict, which can reduce blood flow to the eyes. This can lead to a number of eye problems, including blurred vision, eye strain, and headaches.
Central serous chorioretinopathy (CSC) is a condition that affects the macula, the central part of the retina. The macula is responsible for sharp central vision. In CSC, fluid leaks into the space between the retina and the choroid, which is the layer of tissue that nourishes the retina. This can cause blurred vision, distortion of vision, and loss of central vision.
Research has shown that people with high levels of cortisol are at increased risk of developing CSC. This is thought to be because cortisol can damage the blood vessels in the choroid and make them more leaky.
If you are experiencing stress and eye problems, it is important to see an eye doctor to rule out any underlying eye conditions. Your eye doctor can also advise you on ways to manage stress and reduce its impact on your eyes.
