What is retinitis pigmentosa?

The rpigmentary ethinosis, also known as retinitis pigmentosa or pigmentosa, is a disease encompassed in a group of hereditary genetic disorders that affect the retina, causing its progressive degeneration and slowly decreasing the visual acuity of the sufferer.

The retina is the layer that internally covers the eye and where the electrical impulse that sends the images to the brain is generated. In pigmentary retinosis a gradual destruction of some retinal cells, mainly of the sticks, which control night vision and cones, responsible for peripheral vision.

Causes

Retinitis pigmentosa is a rare disease that affects approximately 1 of each 4.000 person.

This condition It is caused by the presence of genetic defects, so it is a disease with a strong hereditary component. These genetic defects eventually affect the cells of the retina, giving rise to the disease.

This pathology is more common in men than in women, so having a relative with retinitis pigmentosa and being male, are risk factors in this condition.

It is important to highlight that half of the patients do not have a family member known to have the disease, so the genetic diagnosis is very important to know the type of inheritance and transmission of the disease

Symptoms of retinitis pigmentosa

The first symptoms usually appear during childhood or youthHowever, due to the slow progression of the disease, the most important signs do not usually appear before adulthood.

It is important to highlight that each patient may present different signs and with a different advance, however the most common symptoms are:

  • Reduced night vision in areas with poor illumination, being the most common symptom in retinitis pigmentosa. At the beginning the person has difficulty moving in spaces with low light, a condition that increases progressively.
  • Loss of peripheral vision, which produces an evident narrowing of theampor visual This is known as tunnel vision.
  • Once the disease has advanced, there is an important visual acuity reduction. There is difficulty reading and perceiving images in detail.
  • Other symptoms are flashes of light or photopsies, inability to perceive colors and, in advanced cases, blindness.

Associated diseases

In addition to the symptoms associated with retinitis pigmentosa, this disease commonly leads to the suffering of other visual conditions such as:

These pathologies are treatable, therefore it is very important to go to frequent ophthalmological reviews to avoid additional complications.

Treatment of retinitis pigmentosa

There is no specific treatment for this disease, although some forms may benefit from a reinforcement therapy with vitamins, minerals or other principles.

La visual therapy focused on improving contrast sensitivity has been very effective in these patients. Its application requires to apply some exercises monitored by the ophthalmologist, which the patient can perform at home and that represent a significant improvement of visual conditions.

Use sunglasses to avoid retinal damage as much as possible, and going to the ophthalmologist periodically is very important, as some complications of this condition, such as cataracts, can be treated effectively to prevent premature degeneration.

Despite visual loss, patients with retinitis pigmentosa can live their lives adapting to the situation through some rehabilitation services which are now available.

The importance of visual controls

Eye diseases can appear at any age and often it is not until the condition has advanced that the first symptoms occur.

Some alterations do not cause symptoms until the disease has caused irreversible damage, however the periodic visual exams they are essential because they allow us identify the presence of certain conditions early, what can be a decisive factor to ensure the welfare of our eyesight.
