- Posterior vitreous detachment
The inside of the eyeball is filled with a transparent gel-liquid called “vitreous”. Often, with advancing age, the vitreous fluid loses its gel consistency and shrinks. With this shrinkage, the vitreous separates from the back wall of the eye. This separation is called "posterior vitreous detachment".
Posterior vitreous detachment may occur earlier, as well as with advancing age, after blows to the eye, high degree of myopia, some familial hereditary diseases, and previous eye surgeries. .
- What are the symptoms of posterior vitreous detachment?
Posterior vitreous detachment may cause the following symptoms:
- Floaters, particles, spider webs especially noticed when looking at white, shiny surfaces
- Flashes of light (visible when the eye is open or closed)
Posterior vitreous Retractions on the retina causing floaters and flashes of light in detachment
Posterior vitreous detachment is not the same as retinal detachment, which occurs due to a tear in the eye and requires treatment. However, the risk of tears and retinal detachment increases slightly during and especially in the first 12 months after posterior vitreous detachment occurs. Therefore, a patient with symptoms of posterior vitreous detachment must undergo a retinal examination.
If retinal detachment occurs, 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 as follows:
- Flashes of light felt when the eye is open or closed (as in posterior vitreous detachment)
- Sudden impact of a larger number of 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 you experience the above symptoms If one or more of them are present, a retinal examination should be performed without delay.
In retinal detachment, intraocular fluid leaks between the retina and the eye wall through the retinal tear.
- RETINA DETACHMENT. NI
As a result of the contraction of the vitreous fluid that fills the inside of the eyeball, this gel-like fluid separates from the back wall of the eyeball. This condition is called posterior vitreous detachment. In some cases, during the formation of posterior vitreous detachment, a tear may occur in the nerve layer called the retina. The symptoms of a retinal tear are almost the same as the posterior vitreous detachment mentioned in the previous section. After a retinal tear occurs, intraocular fluid passes through this tear between the retina and the underlying wall, causing the disease called "retinal detachment".
- What are the Symptoms of Retinal Detachment?
Retinal detachment is an urgent disease that can result in vision loss. That's why its symptoms are important.
These symptoms are as follows:
If one or more of the above symptoms are present, a retinal examination should be performed without delay.

What is the Treatment of Retinal Tear?
Early detection of retinal tear and It is extremely important to detect and treat retinal detachment before it develops. Symptoms of a retinal tear are flashes of light and floaters. If these symptoms occur, a retinal examination should be performed as soon as possible.
If a retinal tear is detected during the examination and it is suspected that this tear may cause retinal detachment, it must be treated. In the treatment, the tear is closed with laser.

What is Retinal Detachment Treatment? ?
If retinal detachment develops, surgical intervention, that is, surgery, is required. The surgical method may cause retinal detachment. It may vary depending on the number, size, location and shape of the retinal tear and the duration of retinal detachment.
- External collapse method (scleral collapse method):
In detachment surgery. It is the oldest method used. By placing a piece of hard silicone on the outer wall of the eyeball, corresponding to the area of the retinal tear, depression is applied and the retinal tear is closed externally with this application. If the retinal tear is closed with this external intervention, the retinal detachment fluid (liquid accumulated under the retina) is absorbed by the eye in a short time and healing is completed.
The retinal tear is closed by the scleral collapse method. closure
- Vitrectomy:
If it causes retinal detachment If the tears are numerous, large, located differently than usual, if the tear cannot be detected, if there are other accompanying diseases (such as intraocular bleeding), or if time has passed, it may be necessary to perform vitrectomy surgery. In vitrectomy surgery, retinal detachment is treated from inside the eye. For this purpose, small holes are made in the eyeball, 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, and laser treatment is applied. At the end of the surgery, it is necessary to inject a tampon into the eye to ensure that the laser treatment adheres to the torn area and to maintain this effect. Depending on the situation, this buffer material may be air and similar gases, or silicone oil. After the surgery, the patient must use protective eye drops for a while and lie in a certain head position.

Retina Who Should Have a Retinal Examination in Terms of the Risk of Tear and Retinal Detachment?
People who experience flashes of light and sudden floaters in their eyes should definitely be examined for retinal tears. Especially those with high myopia, those who have had an eye injury, those who have had cataract surgery before Those who have undergone eye surgery such as, those with a family history of laser treatment or retinal surgery due to retinal tear, or those with a history of laser treatment or retinal surgery due to retinal tear in the other eye should take such complaints of light flashes and floaters seriously and should undergo a retinal examination as soon as possible.
