Retinal Detachment

Retinal Detachment


Posterior Vitreous Detachment

 

 

 

 

 

 

 

 

The inside of the eyeball is filled with a transparent gel-liquid called "vitreous". Often with the advancement of age, the vitreous fluid loses its gel consistency and shrinks. With this shrinkage, the vitreous separates from the posterior wall of the eye. This separation event is called "posterior vitreous detachment". In addition to advancing age, posterior vitreous detachment may occur earlier, after eye hits, high myopia, some familial hereditary diseases, and previous eye surgeries.

What are the symptoms of posterior vitreous detachment?

Posterior vitreous detachment can give the following symptoms:
- Flying spots, bodies, spider webs that are especially noticeable when looking at white, shiny floors
- Light flashes (visible with eyes open or closed)

Posterior vitreous detachment is not the same as retinal detachment, which is caused by a rupture in the eye and requires treatment. However, the risk of rupture and retinal detachment increases somewhat during and after the formation of posterior vitreous detachment. Therefore, a patient with symptoms of posterior vitreous detachment must undergo a retinal examination.

If retinal detachment has occurred, this may result in vision loss if not treated within a short time. Therefore, it is important to know the symptoms of retinal detachment. These symptoms are:

- Light flashes that are felt when the eye is open or closed (as in the back vitreous detachment)
- The sudden appearance of more flying objects
- Gray-black curtain developing from any direction within the visual field
- Blurring or loss of vision that does not go away with blinking

 

RETİNA DEKOLMANI

In retinal detachment, intraocular fluid leaks between the retina and the wall of the eye, as the retinal ruptures. As a result of the shrinkage of the vitreous fluid that fills the eyeball, this gel-like fluid separates from the back wall of the eyeball. This condition is called posterior vitreous detachment. During the formation of posterior vitreous detachment, in some cases, a rupture of the nerve layer called retina may occur. Symptoms of retinal tear are almost identical to the posterior vitreous detachment mentioned in the previous section. After the rupture of the retina occurs, the intraocular fluid passes through this rupture between the retina and the wall underneath, causing a disease called “retinal detachment”.

What are the symptoms of retinal detachment?

Retinal detachment is an urgent disease that can result in vision loss. So its symptoms are important. These symptoms are:

Light flashes that are felt when the eye is open or closed (as in posterior vitreous detachment)
The sudden appearance of more flying objects
Gray-black curtain developing from any direction within the visual field
Blurring or loss of vision that does not go away with blinking

If a retinal tear was detected during the examination and it is suspected that this tear may cause retinal detachment, it should be treated. In the treatment, it is closed with a torn laser.

It is extremely important to detect the retinal tear early and to detect and treat the retinal detachment before it develops. Symptoms of retinal tear are light flashes and flying objects. If these symptoms occur, a retinal examination should be undertaken as soon as possible.

What is the Treatment of Retinal Tear?

If a retinal tear was detected during the examination and it is suspected that this tear may cause retinal detachment, it should be treated. In the treatment, it is closed with a torn laser.

What is Retinal Detachment Treatment?

If retinal detachment has developed, surgical intervention, ie surgery, is required. The method of operation can vary depending on the number, size, location, shape and duration of retinal detachment that cause retinal detachment.

External buckling method (scleral buckling method):

It is the oldest method used in detachment. Corresponding to the retinal rupture area, a piece of hard silicone is placed on the outer wall of the eyeball, and the retina rupture is closed with this application from the outside. If the retinal tear is closed with this external intervention, retinal detachment fluid (fluid accumulating under the retina) is absorbed by the eye within a short time and recovery is completed.

Vitrectomy:

If the ruptures causing retinal detachment are large, large, their locations are different than usual, if no tears can be detected, other accompanying diseases (such as intraocular bleeding) or if time has passed, vitrectomy surgery may be required. In vitrectomy surgery, retinal detachment is intervened through the eye. For this, small holes are drilled in the eyeball, and the vitreous fluid is cleaned with the help of some cutting and aspirating rods (probes) and light sources, the fluid accumulated under the retina is aspirated, the tears are closed, laser treatment is applied. At the end of the operation, it is necessary to apply a tampon in the eye to adhere the torn area of ​​the applied laser treatment and continue this effect. Depending on the situation, this buffer can be air and similar gases, or silicone oil. After the operation, the patient should use protective ophthalmology for a while and lie in a specific head position.

Who Should Be Retinal Examination for Retinal Tear and Retinal Detachment Risk?

Persons with light flashes and sudden flying objects should definitely be examined for retinal tears. Especially those with high myopia, those who have had a blow to the eye, those who have had eye surgery such as cataract surgery, those who have had a history of laser treatment or retinal surgery due to a retinal tear in their family, those who have a history of laser treatment or retinal surgery due to a retinal tear in the other eye, he should take flight complaints seriously and undergo a retinal examination as soon as possible.
