Retinal Diseases

Diseases of the retina are many varieties and most of these are caused by visual symptoms. Treatment is available for some retinal diseases. Retinal diseases can be treated in our Izmir hospital.

Retinal Diseases

What is Retina?

The retina is the vascular nerve layer in the back of the eye, consisting of 10 separate layers, where the visual cells of the eye are located.

Diseases of the retina are very diverse and most cause visual symptoms. Retinal diseases can affect any part of your retina, a thin layer of tissue found on the inside of the back wall of your eye.

The retina is the name given to the area where we have millions of visual cells and where the vascular nerve layer of the eye is located. It is the tissue that covers the very back of the eye like wallpaper.

If we compare the eye with a camera, the retina layer coincides with the film part of the camera. It receives and organizes the visual information coming to the eye and sends it to our brain via the optic nerve and enables the perception of the image in the brain.

Treatment is available for some retinal diseases. Depending on your health situation, treatment aims may be to stop or slow the disease and protect, improve or restore your vision. Some untreated retinal diseases can cause severe vision loss or blindness.

What Are The Symptoms of Retinal Diseases?

  • Flashes of light,
  • Dark objects floating in front of the eyes,
  • Veiling the vision,
    Broken-curved vision,
  • Vision loss suddenly or slowly,
  • Short-term vision loss,
  • Occurring of dark areas in the field of vision.

Flashes of light: It’s typical for retinal detachment, generally. In addition, it is a finding that occurs when the gel inside the eye tries to separate from the retina, on which it is attached, during the innocent separation over time, in places where it has strong adhesions. As long as it does not create a tear, it is a completely natural process, after a while, when the separation from the place where it has strongly adhered to is completed, the flashing will also end.

Dark bodies floating in the eye (flying flies): The most innocent example is a finding that occurs when the vitreous gel in the eye begins to deteriorate in time. However, more dangerously, dark objects can be seen in retinal detachment or intraocular hemorrhage.

Normally, if we think of our eyes like a balloon, there is a transparent gel in the consistency of egg white, which is known as vitreous, in order for this balloon to remain voluminous. It is completely transparent in a healthy eye and cannot be seen because it is transparent, we are not even aware of its existence. This gel inside the eye rests on the behind of the retina layer and is firmly adhered to in some places.

In time, the structure of this gel may deteriorate although it is usually the same with age, sometimes this deterioration can occur at a young age. This deterioration has no effect on the visual function of the eye, but they are seen as floating particles in front of the eye. Sometimes they can be seen as threads, as dots, as spider webs, and as larger described objects.

These objects move in all directions with the movement of the eye because they are floating in the cavity of the eye. There is no need for any treatment because they are innocent, but if the number increases too much to impair the patient's vision, laser treatment or surgical treatment can be planned.

Veiling of vision: It is also typical in retinal diseases. It is usually a sign of retinal or vitreous hemorrhage or retinal detachment.

Broken-curved vision: Generally, this disease is typical for yellow spot disease.

Vision loss suddenly or slowly: Retinal diseases have more or less vision loss typically. Sudden vision loss is seen in vascular occlusions or vitreous hemorrhage, while slower vision loss is typical of retinal detachment.

Short-term vision loss: It can occur even changes in blood pressure suddenly, as well as ocular migraine or often a temporary ischemic attack. It is gratifying that it is temporary, but treatment towards to cause and consultations and, examinations of the relevant internal unit are very important.

Occurring of dark areas in the field of vision: It often occurs as a result of intraocular bleeding or malnutrition.

What Are Retinal Diseases?

As retinal diseases can be examined in a much broader classification, I found it more appropriate to talk about the retinal diseases we see here in order of frequency. Major retinal diseases are:

  • Bleeding due to diabetes and hypertension,
  • Yellow spot disease,
  • Retinal detachments/tears,
  • Retinal vessel occlusions,
  • Macular holes, macular edema,
  • Congenital retinal diseases,
  • Retinal tumors.

What causes retinal diseases?

  • Age.
  • Cigarette,
  • Intense sunlight (UV) exposure,
  • Having uncontrolled systemic disease, especially diabetes and hypertension,
  • Eye trauma,
  • Having a family history of retinal disease.

Retinal Diseases Treatment Izmir, Turkey

Retinal diseases can be treated in our Izmir hospital. Although we have different treatments depending on the diagnosis of the disease, retinal diseases can sometimes be treated with medication, sometimes with laser therapy, and sometimes with back-eye surgeries called vitrectomy. It is useful to know that retinal diseases are diseases that require long-term follow-up and treatment, and regular controls are as important as the treatment of the disease.
