Central serous chorioretinopathy

ALL YOU NEED TO KNOW ABOUT...

  • It is the fourth retinal disease that threats our vision.
  • If you experience blurred vision, perception of a central spot, straight lines that seem bent or you have troubles in focusing when reading, you should go to the ophthalmologist in order to be diagnosed.
  • It is more frequent in young men, even though women, usually at a more advanced age, may also suffer it.
  • Stress, pregnancy and corticoids intake, as well as other hormonal disorders, are the main risk factors of the disease.
  • Its acute form does not require in most of the cases a treatment, as it resolves spontaneously in around three months, but the chronic form does indeed require a treatment.

Central serous chorioretinopathy. Blurred vision and central spots.

In case of blurred vision, perception of a central spot, straight lines seem bent or you have troubles in focusing when reading, you should go to the ophthalmologist. It could be a central serous chorioretinopaty or other retinal problems. Stress, pregnancy or corticoids intake are some of its risk factors.

Blurred vision

Decrease in vision

Central spot in vision

Lines seem bent when reading

Problems in focusing

The objects seem smaller than they are

Symptoms of central serous chorioretinopathy

It is very important to go to the ophthalmologist to be correctly diagnosed.


What kind of disease is central serous chorioretinopathy?

Central serous chorioretinopathy is not a frequent disease, but it is important to consider it because it is the forth retinal disease that most threatens our vision behind age-related macular degeneration, vascular occlusions or diabetic macular edema.


Who is at a higher risk of suffering it?

It is a disease which is usually diagnosed among young male patients, between their thirties or forties, although according to the latest population studies, women may also suffer it. In such cases, it often appears at a more advanced age.


How is the disease detected?

This disease requires a good differential diagnosis, which means it is important to differentiate the disease from other similar diseases, such as polypoidal vasculopathy (a type of age-related macular degeneration), the Vogt-Koyanagi-Harada disease (a type of uveitis), benign tumors (such as nevus or hemangiomas), or more dangerous and malign tumors (such as melanoma or lymphoma).


What are its symptoms?

Patients come to the ophthalmology consulting room reporting:

  • Diminished and blurred vision.
  • Scotomas or central defects in visual field that the patient perceives as a central motionless dark spot (black or greyish) that prevents or hinders reading.
  • Lines are bent when reading.
  • Feeling that objects are smaller than they really are.

What kinds of central serous chorioretinopathy are there?

It is important to differentiate between two types of central serous chorioretinopathy, depending on its length:

  • Acute central serous chorioretinopathy
  • Chronic central serous chorioretinopathy

Acute central serous chorioretinopathy lasts for a short time and is self-limited (it resolves spontaneously), reason why the visual prognosis is good. In these cases, we need to wait approximately three months in order to assess its progression.

In chronic central serous chorioretinopathy, sequels are more serious. The decrease in visual acuity is caused by anatomical alterations. Irreversible changes occur in the pigment epithelium, a layer located under the retina which is essential to well-functioning photoreceptors. Therefore, it is important to get properly diagnosed in order to determine a treatment, when necessary.


Why does this happen?

In spite of the high number of studies and interest shown regarding this disease, it is not known for sure. There are several theories. One of the most important ones and with a more solid scientific base is a theory based on the hormonal imbalance, for which glucocorticoids act like mineralocorticoids and cause an inflammation in the choroid, a vascular tissue that nourishes our eyes and is located under the retina.


What does retinopathy exactly consist in?

When there is a vascular inflammation, vessels dilate and become permeable. If there is an increase in blood vessels permeability, fluid leaks out and accumulates on the choroid and is retained by the pigment epithelium. But over time, this barrier becomes inefficient and the fluid runs under the retina. This is how central serous chorioretinopathy occurs.


What causes the hormonal disorder?

  • One of the factors is hormonal imbalance. This factor has been known for a long time. It affects specially young men in management positions who suffer from work stress.
  • Moreover, the intake of corticoids is also a risk factor, regardless of whether it is a pomade for skin, an inhalator for asthmatic patients or corticoids administered intravenously. Any intake of such medicines may imbalance the hormonal state and lead to a central serous chorioretinopathy.
  • Other hormonal alterations, such as Cushing syndrome or pregnancy, during which many hormonal imbalances occur, may lead to this disease.

May other factors cause it?

Besides factors directly related to hormones, other risk factors have been studied:

  • Presence of helicobacter pylori, a bacteria which can live inside the stomach and cause an inflammation on its tissue.
  • Treatments for depression, anxiety, insomnia (sleeping troubles) may also trigger a central serous chorioretinopathy.
  • Patients with cardiovascular risk factors, such as hypertension, ictus or infarction are also at a higher risk of suffering the disease, according to new population studies.

How is it diagnosed?

Diagnosis starts by an identification of symptoms, such as blurred vision, perception of a central spot, bent lines… That is the beginning of it.

We perform a non-invasive examination, examining the eye fundus with the slit lamp and the use of lenses. We also use a more advanced equipment called OCT (Optical Coherence Tomography). It is a retinal study performed by means of light beams which shows as the retinal tissues and allows us to see in a direct way the liquid accumulated under the retina. It is important the use of the EDI-OCT option, available at our center, in order to examine in detail the choroid, where the disease is located.

In case that the disease is chronic or that we suspect the liquid accumulated under the retina is caused by another disease, we need to use invasive tests empoying a contrast administered intravenously, such as fluorescein or green indocianine angiography. These tests are also used to determine the treatment. They show the state of the choroid and the location of the leakage point through which the fluid accumulated under the retina leaks. There are other functional tests that we may use in order to determine whether photoreceptors have experienced irreversible changes due to the disease. These include visual field, multifocal electroretinogram and microperimetry.


How is central serous chorioretinopathy treated?

The treatment will depend on the type of central serous chorioretinopathy.

Acute form

In case of an acute central serous chorioretinopathy, it is not usually recommended to apply any treatment, as in 80-90% of cases, it resolves on its own. The only thing we need to do is to monitor the patient and perform the necessary regular controls.

Chronic form

In case the disease does not resolve on its own, is recurrent or the patient has very low vision or requires good vision for professional matters, a treatment must be planned.

  • The disease may be associated to corticoids intake, reason why the use of such medicines will need to be stopped after consulting with the specialist who prescribed them.
  • We may also try to reduce the level of stress, even though it is difficult, but patients usually improve practising sports or yoga and trying to see their lives differently.
  • One of the most used treatments, that has a more solid base is photo-dynamic therapy. This treatment has an efficiency of approximately 86% and it decreases the disease recurrence. In 40% of cases, the disease may appear again, reason why using a treatment that decreases such changes is important. Photo-dynamic therapy is an invasive treatment, as a photosensitive substance is injected. This helps us direct the laser treatment only to the affected area, that is where the substance accumulates in the eye.

Other treatments being developed

Other types of treatments that are currently being studied include the use of micropulse laser. It seems a good alternative, although the study results are still to be confirmed.

Patients are also treated with anti-VEGF intravitreous injections of a substance known as vascular endothelial growth factor, whose use is known as a treatment against ARMD or diabetic macular edema. This drug is currently widely used in ophthalmology.

There are also pharmacological treatments with still non proved scientific based, but the first studies performed reveal its possible efficacy. These are mineralocorticoid inhibitors, such as epleronone or spironolactone.


When should I go to the ophthalmologist?

In case you have symptoms like:

  • Decrease in vision
  • Blurred vision
  • Vision of a black motionless spot
  • Vision of bent lines and troubles in reading

It is important to go to the ophthalmologist not only because it might be a central serous chorioretinopathy, whose chronic form requires in most of the cases a treatent, but also because a good differential diagnosis is needed for an early diagnosis of diseases like ARMD, that has the same symptoms.
