CENTRAL SEROUS RETINOPATHY

Central serous retinopathy is a condition whereby the Retinal detaches it self from the underlying tissues as a result of fluid leakages..

This condition can be as a result of stress. Stress causes an increase in the release of cortisol which triggers inflammatory responses and ultimately fluid leaks into the layers of tissues underneath the retina. Other known causes are regular use of steroid medications, autoimmune conditions.

Signs and symptoms includes, reduced vision, blurry vision, distorted vision.

Treatment is done by surgical sealing and reattaching the detached retina.

IF YOU DONT KILL STRESS, YOU MAY GO BLIND

Many people just believe that the only impact stress has over one’s health is hypertension.

Shockingly there is a whole lot of issues that can arise if one is unable to control their stress level.

The bedrock of all the issues that arise from stress is the release and increase of stress hormone, known as CORTISOL.

Increased level of cortisol in the blood is a precursor to so many issues which includes increased blood pressure, increased heart rate, diabetes…

But for the sake of our topic, we will focus on how stress affects the eyes directly.

Once cortisol is released, it triggers inflammation and leakage of fluid Under the retina. This fluid causes the Retinal to detach from the underlying tissues, causing a condition known as central serious retinopathy.

This condition requires a surgical intervention and can result in blindness if not treated urgently.
