What is retinal detachment?
The thin nerve layer that surrounds the inner surface of the eye like a sheet and creates visual signals is called the retina. retinal detachment On the other hand, it is a disease caused by the separation of the retina from the tissue to which it is attached. Detachment of the retina is mostly the tear that occurs in the retina and this split It happens due to fluid leaking from its place under the retina. In retinal detachment, the nutrition of the retina is impaired and if not treated quickly, vision loss becomes permanent. So it can blind. So retinal detachment emergency treatmentIt is a necessary disease.
What are the causes of retinal detachment?
There are 3 types of retinal detachment according to the way it occurs.
Torn retinal detachment: This is the most common type. The jelly-like fluid that fills the cavity of the eye liquefies and shrinks due to age or trauma. During this shrinkage, a hole or tear can occur in the retina. If this tear is not noticed and treated and fluid enters through the hole, the retina may detach. We call this condition a ruptured retinal detachment.
Tractional retinal detachment: In diabetes, trauma or some eye diseases, shrinking membranes occur in the eye. These membranes can pull and detach the retina.
Serous retinal detachment: Excess fluid flows through the vessels under the retina, often for reasons such as eye inflammation or trauma. This causes fluid accumulation under the retina and detachment of the retina. There are no tears or holes in this type of detachment.
What are the symptoms of retinal detachment?
There is no pain in retinal detachment. Beginner fly flyas black spotsto be seen, Spider web shaped shadows or images such as a gauze curtain can be signs of retinal tear. Specifically, these complaints flash of light Accompanying it is a symptom that increases the possibility of rupture. When the retina detaches and detaches, there is a narrowing in the visual field, as if the curtain is closing on one side. As the disease progresses, vision may be completely lost. If these complaints develop, an ophthalmologist should be consulted urgently.
How to diagnose retinal tear and detachment:
The patient’s pupils are dilated with the help of drops, and retinal examination is performed with the help of a device called a biomicroscope. In this way, the hole, tear and detachment area in the retina are determined. Sometimes there may be bleeding in the eye and it may make direct examination difficult. In such cases, an eye ultrasound may be required.
What are the risk factors for retinal detachment?
Past eye surgery (such as cataract surgery)
Prior retinal detachment in one eye
Presence of thinning areas in the retina
How are retinal tears and detachment treated?
Rupture treatment with laser is a very easy procedure that can be done in the outpatient setting. If tears are detected before detachment develops, laser treatment is applied around the tears and the development of detachment is prevented. Therefore, early diagnosis is very important. If the liquid has passed under the retina, it means that the laser treatment phase has passed and the surgery has become mandatory.
If the detachment has developed, the only option is surgical treatment. Various methods can be applied in surgical treatment according to the clinical picture. These are injecting gas into the eye and laser, buckling surgery and vitrectomy surgeries. The aim in all of them is to remove the fluid that causes the detachment, to soothe the retina and to close the tears.
Intraocular gas More fluid is prevented from entering the tear, and laser or cryo treatment is performed around the tear by soothing the retina. It can be applied in certain cases caught early.
In the treatment of collapseWithout entering the eye, the tear is closed by collapsing the eye from the outside with a silicone band from the outside, and laser or cryotherapy is performed to ensure the adhesion of the tears.
vitrectomy surgery, In vitrectomy surgery, very small holes are made in the eye and the eye is entered. The eye gel is cleaned, the fluid under the retina is drained, and a laser is applied around the tears. In this surgery, all recessions can be cleaned and tears or small holes that may be overlooked in other methods can be detected and treated. At the end of the surgery, gas or silicone is injected into the eye. The purpose of this is to prevent the tears from reopening until they are permanently adhered.
What should be the expectation after retinal detachment surgery?
Retinal detachment is a disease that causes blindness if left untreated. The increase in vision can sometimes last for months or even 1-2 years. The most important factor affecting surgical success and increase in vision is the time between the onset of the disease and surgery. Therefore, early diagnosis and treatment is very important in this disease.
