Posterior Vitreous Detachment
 
In addition to advancing age, posterior vitreous detachment may be seen earlier in the eye, as well as in myopia, a number of familial hereditary diseases, and earlier eye surgeries. Often, with advancing age, the vitreous fluid loses its viscosity and contractes. With this shrinkage, the vitreous is separated from the posterior wall of the eye. This separation is called ”posterior vitreous detachment“.
 
What are the symptoms of posterior vitreous detachment?
 
Posterior vitreous detachment may give the following symptoms:
- Spotted spots, bodies, spider webs, especially when looking at white, bright floors
- Light flashes (visible when the eye is open or closed)
 
 
If retinal detachment occurs, this may result in loss of vision if not treated within a short period of time. Therefore, it is important to know the symptoms of retinal detachment. These symptoms are as follows: Rear vitreous detachment is not the same as retinal detachment that occurs with the formation of tears and requires treatment. However, the risk of rupture and retinal detachment is slightly increased during the formation of posterior vitreous detachment and especially within the first 12 months after formation. Therefore, a patient with posterior vitreous detachment symptoms must undergo a retinal examination.
 
- Light flashes when the eye is open or closed (as in the posterior vitreous detachment)
- sudden emergence of more flying objects
- Gray-black screen that develops from any direction within the visual field
- Blurred vision or loss of blurred vision
 
If one or more of the above symptoms are present, a retinal examination should be performed without delay.
 
As a result of the shrinkage of the vitreous fluid filling the inside of the eyeball, this liquid in the gel consistency is separated from the rear wall of the eyeball. This is called posterior vitreous detachment. During the formation of posterior vitreous detachment may occur in some cases ripped in the nerve layer called retina. Symptoms of retinal tear are almost identical to the posterior vitreous detachment referred to in the previous section. After retinal tears, the intraocular fluid passes from this tear to the wall between the retina and the underlying wall and causes the disease called altındaki retinal detachment sonra.
 
What are the Symptoms of Retinal Detachment?
 
Retinal detachment is an urgent disease that may result in loss of vision. Therefore its symptoms are important. These symptoms include:
 
Light flashes when the eye is open or closed (as in the posterior vitreous detachment)
Sudden emergence of more flying objects
Gray-black curtain evolving from any direction within the visual field
Blurred vision or loss of blurred vision
Early detection of retinal tears and the detection and treatment of retinal detachment before development is extremely important. Symptoms of retinal tears are light flashes and floating objects. If these symptoms occur, a retinal examination should be performed as soon as possible. What is the treatment of retinal tears?
 
If a retinal tear is detected during the examination, it is necessary to treat it if it is suspected that it may cause retinal detachment. In the treatment, it is covered with torn laser.

What is Retinal Detachment Treatment?
 
If retinal detachment is developed, surgical intervention is necessary. The method of surgery may vary depending on the number, size, location, shape and duration of retinal detachment of the retinal tear that causes retinal detachment.
 
- External collapsing method (scleral buckling method):
It is the oldest method used in detachment surgery. Retinal rupture is applied to the outer wall of the eyeball and the retinal tear is closed by this application. If the retinal tear is closed by this external intervention, retinal detachment fluid (fluid accumulated under the retina) is absorbed by the eye in a short time and the healing is completed.
 
 
If the number of tears that cause retinal detachment is large, if their place is different than usual, if the tear cannot be detected, if there are other diseases (such as intraocular bleeding) or if over time, vitrectomy operation may be necessary. In vitrectomy surgery, retinal detachment is intervened through the eye. For this purpose, small holes are opened in the eyeball and a number of cutting and aspirating bars (probes) and light sources of the vitreous fluid is cleaned, the liquid under the retina is aspirated, tears are closed, laser treatment is applied. At the end of the operation, it is necessary to give a buffer in the eye for the applied laser treatment to adhere to the torn area and to continue this effect. Depending on the case, this buffer can be air and similar gases, or silicone oil. After the operation, the patient used protective preservative for a while and
