Retinal detachment

El Retinal detachment is the separation of the retina from the posterior wall of the eyeball, known as choroids. When the retina separates from the choroid, the vitreous humor enters the subretinal space that has created the detachment.

The most common type of retinal detachment is the rheumatogen, but there are other types like exudative retinal detachment or tractional retinal detachment.

What is retinal detachment?

El retinal detachment It occurs when, due to a tear, the retina separates from its normal position. This condition is considered a ophthalmic emergencyThis is why it is important to learn to recognize your symptoms and in what cases you present to see a specialist as soon as possible.

The retina is a light-sensitive nerve fiber tissue that is necessary for proper vision because it allows you to perform daily tasks like reading or driving clearly. Is pathology can occur in people of any agebut usually more frequent in people over 40, in patients with a very high myopia and also in those who suffer from other disorders of the retina. Less frequently, it is related to hereditary diseases, so it can occur even in children. Treatment should not be postponed as can end in visual impairment or irreversible loss of vision.

Causes

Most retinal detachments are caused by the presence of hemorrhages or tears in the tissue structure of the retina. Inside the eye is the vitreous humor, a gelatinous structure that is firmly attached to the retina at some specific points. A vitreous traction It can cause a tear or a hole in the retina.

Retinal detachment can also occur as consequence of eye aging. Over time the vitreous can end up becoming liquid, which results in its loss of volume and its possible retina detachment. Faced with this picture, the most common is that the patient suffers from a condition known as myodesopsias or fliesHowever, in some cases the condition may progress to retinal detachment.

In addition to the aging process itself, the retinal detachment presents with higher incidence in:

  1. Patients with myopia, especially those with high diopters.
  2. People who have already suffered a tear before or with a family history of this condition.
  3. Cataract surgery.
  4. Those who have suffered a major eye injury.
  5. Patients with diabetes that manifest complications of this condition such as Diabetic retinopathy. When the detachment occurs for this reason, it is known as secondary retinal detachment.

symptom

In most cases, a significant change in the vitreous structure may occur before retinal detachment. First there is a tear in the retina, through which the vitreous humor fluid penetrates, facilitating the separation of the retina and subsequent detachment. The area of ​​the retina that has detached cannot function properly and will produce a blurred vision or a partial blindness o total, depending on the extent of detachment.

Middle-aged people and the elderly can observe floating blackheads y flashes of light in your vision. In most cases these symptoms do not indicate a serious problem, but if there is a sudden and sudden appearance of these blackheads and / or flashes of light, it may indicate a vitreous hemorrhage with a retinal tear.

An ophthalmologist will need to examine the eye to analyze the internal structures and determine if there is retinal detachment. The examination should be performed as soon as the first symptoms appear because a retinal detachment recent can be treated by a surgery before a more severe and irreversible situation occurs.

retinal detachment

Some retinal detachments can be initiated without the presence of floating points or light flashes. In these cases, patients may notice a undulation or veil in your vision or the appearance of a shadow in the lateral areas of the campor visual.

The development of this condition will cause a blur in central vision and will create a significant loss of vision if it is not treated quickly and efficiently.

Retinal detachment treatment

If one or more of the symptoms mentioned above are perceived, it will be essential to see an ophthalmologist. Because the retinal detachment does not manifest externally, to diagnose it the specialist will have to perform a detailed examination in order to confirm this condition. Optical coherence tomography is one of the most used methods for its diagnosis.

Once the retina detaches, the only way to repair it is by surgical intervention. A treatment of laser photocoagulation in the case of those patients who only have the torn retina, without the separation being presented yet, however when it is detaches la intervention It is highly recommended, on the contrary the affected eye could be incapacitated and the blind patient.

In the case of severe retinal detachmentThere are several surgical treatments, the most common is the vitrectomy. In this procedure you removes the vitreous for later replace it with another material, usually saline, intraocular gas or silicone oil, which will serve to place the retina in its original position. This procedure is ambulatory and it is done with Anesthesia local.

After the intervention, the ophthalmologist may indicate the use of anti-inflammatory or antibiotic drops, in addition to pupil dilators. Depending on the matrix that has been introduced stance that must be acquired, the Recovery time and the recommendations may varyThat is why it is important to follow the doctor's instructions to the letter. Although this procedure is generally successful, the outcome of the intervention will depend on various factors such as the severity of the detachment or the patient's risk history.

Prevention of retinal detachment

It is not possible to prevent retinal detachmentHowever, there are people with risk factors. That is, patients with high myopia or magna, with family background of this condition or who have already suffered from it in the past, they should go to periodic ophthalmologic check-ups to ensure eye health. A timely review can determine the existence of a tear, which will lead to the application of a treatment to prevent the condition from evolving.

Similarly, those who suffer from myodesopsies they will have to go to their medical check-ups and, in the case of seeing that the floating spots increase or that new symptoms appear, go quickly to a specialist.
