Thrombosis in the eye Symptoms, the course of the disease and consequences
How is a thrombosis noticeable in the eye? What effects can a missed treatment have on people’s eyesight? Find out everything below about the symptoms, the course of the disease and the consequences of an eye thrombosis.
What are the symptoms of an eye thrombosis?
Symptoms of an eye thrombosis include:
- A veil over the affected eye
- Distortions in the field of view
- blurred vision
- more or less sudden loss of vision
- a yellow spot in the field of vision
- up to blindness
The mentioned symptoms of a thrombosis in the eye occur relatively suddenly. Those affected notice the change within a few days or hours. It is not uncommon for the visual impairment to be greater after waking up than in the evening. This is due to the fact that when you are lying down, the pressure in the eye veins increases and the blood is less well drained in this position. The strength of the visual impairment depends on the location and size of the retinal vein occlusion noticed by the patient. The location and size of the eye thrombosis also have an impact on the course of the disease and the possible consequences. For example, the appearance of a yellow spot is a consequence of the fluid that has accumulated through the vein occlusion – a so-called macular edema.
What types of eye thrombosis are there?
An eye thrombosis can be, depending on the position of the occlusion in the eye, a central vein occlusion or a branch vein occlusion.
Central vein occlusion
If the central vein of the retina is blocked, we call this a central vein occlusion. The entire retina is then affected by the reduced blood flow.
Branch vein occlusion
If a vein occlusion is in the area of the previous veins, it is referred to as a branch vein occlusion. This form of thrombosis in the eye occurs five times more often than central vein occlusion.
The course of an eye thrombosis
Eyesight deteriorates if the eye thrombosis is left untreated. In the course of the disease, the vessels expand around the area affected by the eye thrombosis. In order to compensate for the circulatory disturbance in the eye and the associated lack of oxygen, it sometimes happens that new vessels form. These vessels are usually unstable and crack easily, which in turn can lead to bleeding or fluid leakage from the vessels into the eye.
If the vascular changes described are not treated, there is a risk of loss of vision and even blindness. That is why we recommend regular ophthalmological check-ups for high-risk patients.
Consequences of an eye thrombosis
As a consequence of an eye thrombosis, a steady deterioration in vision can be expected if treatment is not taken. As a result of the vein occlusion and the congestion of blood, the vein expands and can become leaky. This allows blood and serous fluid to pass into the retina. Macular edema can be another consequence of a thrombosis in the eye.
Preventing thrombosis in the eye
Do you belong to the risk group for an eye thrombosis ? Then you should not do without regular check-ups by an ophthalmologist. We would be happy to provide you with detailed and individual information about the diagnostic procedures and therapies for thrombosis in the eye .
Don't be afraid of the ophthalmologist!
Our ophthalmological practice has specialized in the detection and treatment of retinal diseases. We use the latest technologies in ophthalmology, work very sensitively, absolutely sterile and particularly precisely, so that examinations and treatment can be experienced quickly and painlessly.
