About The Retina

What is a retina?

The retina is a mesh layer that covers the back wall of the eyeball like a wallpaper and consists of visual cells. At the same time, the retina consists of 10 layers, the retinal layer is the most complex and sensitive point of the eye. The retina allows light to be transmitted to our brain as an image so that we can see. Problems that occur in the retina are not visual disorders, but eye diseases. Early diagnosis is very important at this stage. If you have one or more of the following symptoms, you should visit an ophthalmologist for an examination.

Symptoms of retinal diseases

  • Sudden or slow loss of vision
  • Broken-curved vision
  • Flashes of light
  • Dark spots floating before the eyes (flying flies)
  • Blurred vision
  • Transient and short-term loss of vision
  • Formation of dark areas in the field of view

What retinal diseases exist?

  • Hemorrhage due to diabetes and hypertension
  • Blockage of retinal vessels
  • Retinal detachments/tears
  • Macular disease
  • Congenital diseases of the retina
  • Accumulation of fluid under the retina, retinal edema
  • Macular perforations
  • Vitreoretinal superficial disorders
  • Retinal tumors

Negative effects of diabetes and hypertension on the retina

Diabetes mellitus and hypertension harm all body systems, and first of all, they have the greatest negative impact on the eyes. As a result of these diseases in the retina, vasodilation and impaired permeability occur. For this reason, patients with diabetes and hypertension should be monitored by an ophthalmologist to protect eye health.

Why does a retinal tear occur?

There are three types of retinal tears: retinal perforation, horseshoe tear, and retinal tear. The most common causes of retinal detachment are what we call horseshoe tears, mostly in the form of centrally oriented tears. These tears cause the patient to complain of photopsy (flashes of light). If these tears are accompanied by vascular tears, the patient may also complain of blurred vision. Retinal perforations are oval, but they do not show any symptoms and are considered a natural result of aging. Retinal tears can be seen as a natural result of aging. However, in some cases, retinal perforations may occur as a result of a blow to the eye or a surgery. It is very important for eye health to treat these retinal perforations without delay.

Retinal tear symptoms

  • Flashes of light
  • Narrowing of the field of view
  • Veil in the eyes
  • Blurred vision

Prices for laser treatment of retinal tear

Treatment of retinal tears with photocoagulation is called argon laser therapy. This method treats damaged retinal tissues and prevents further deterioration of the tissues. This procedure is performed painlessly under drip anesthesia. Prices for laser treatment of retinal breaks can be determined as a result of the examination.

About retinal surgery

Retinal surgeries are carried out as a result of a doctor's determination of damage in the retinal area. While major diseases such as retinal detachment are treated with surgery, small retinal perforations can be treated with a laser.

However, early diagnosis, preventive treatment, and proper retinal surgery are of vital importance.

Frequently Asked Questions

What should be done after laser treatment for a retinal tear?

Anesthesia applied after treatment for a retinal tear may cause blurred vision due to the drops and the procedure. Therefore, in the first few hours after treatment, it is not recommended to drive. After treatment, the patient does not need to stay in the hospital. It will be enough to come to the control at intervals set by the doctor after treatment.

Will vision be blurry after retinal surgery?

Eye drops and procedures may cause blurred vision in the patient. For this reason, before treatment, the patient is advised to come with people who can accompany the patient after the treatment.

Does retinal tear lead to blindness?

If retinal detachment is not treated promptly, it can lead to partial or complete loss of vision.

Vitrectomy is an eye surgery that involves removing the clear gel from the inside of the eye and replacing it with a gas or liquid. This procedure is used to treat eye conditions such as retinal detachment, macular degeneration, or retinal tear.

With retinal detachment, consequences in the form of loss of vision can be prevented due to early diagnosis, detailed examination, and timely and, most importantly, correct treatment. Retinal surgeries are sensitive surgeries that require good sterilization measures and the use of high technology, otherwise, vision loss may result.
