Uveitis: inflammation of the choroid in the eyes, reduced or blurred vision

The eyes are a very important method of obtaining information from the environment, so that we know what is going on around us. It is very important that the eyes work properly. It can happen that the field of vision gradually or suddenly decreases, which also makes us sensitive to light. In addition to blurred vision, it causes spots, dots or stripes in the eye. What is uveitis, what causes it and how can it be treated?

Blurred vision, vitreous hemorrhage

The extent to which the condition occurs can vary greatly. In one person, vision changes gradually, while in another an acute painful sting is followed by a vitreous hemorrhage. In both cases, the field of vision of one or sometimes both eyes will decrease. People have spots or strings in the eyes, sometimes causing them to be unable to stand daylight (photophobia). In addition, it is accompanied by eye pain, red eyes and abnormal tear fluid release. This is caused by inflammation in the anterior chamber of the eye, excessive fluid pressure in the eye, cloudy vitreous humor or cornea, cataracts and retinal abnormalities (detached retina). It is recognizable as adhesion of the iris to the lens (normally round shape black lens seems to take on a irregular shape), having white inflammation dots on the inside of the cornea or along the iris edge. In addition, it may involve white deposits in front of the lens or a damaged retina, resulting in eye edema.

Classification of the inflammation

The inflammation can occur in three places in the eye, namely in the front, in the middle or at the back. The following subdivision is used:

  • the iris is inflamed and is therefore called iritis. It causes white deposits to form in front of the lens, dots appear along the iris or against the cornea. This is called anterior uveitis and affects approximately 85% of cases;
  • the vitreous and related surroundings are inflamed. It affects the sclera, lens or retina. It occurs in approximately 10% of cases;
  • In the other cases there is inflammation of the retina itself or the entire eye is affected.

What could be the culprits?

Both physical factors and external influences can cause inflammation. In other words, the treatment can also vary. Consider a growth or damage from a penetrated object. Most cases involve inflammation caused by the following two groups.

Virus or bacteria

There is a virus or bacteria that causes the inflammation. In other words, the body is relatively weakened, which means it can strike. They could be worms or fungi. In addition, bacteria, Lyme disease, TB and leprosy are an important source. Viruses such as HIV and Herpes (related to genital Herpes as well as cold sores) can also be the cause.

Autoimmune disease

An autoimmune disease may be involved. The inflammation is caused by the immune system, because certain anti-inflammatory substances/cells are attacked. This condition often does not occur as a separate inflammation, but is associated with or caused by certain autoimmune diseases. Think of Psoriasis, Crohn’s disease, Ankylosing spondylitis, ulcerative colitis, Multiple Sclerosis (first signal of MS). To confirm the suspicion of an autoimmune disease due to uveitis, an HLA-B27 blood test is often done.

Treatment of uveitis

The eye condition is standardly treated with corticosteroids, which are injected next to or into the eye. This may also involve eye drops to improve the condition of the eye. If there is excess pressure in the vitreous, a small drain can relieve the pressure. If the condition is caused by an autoimmune disease, the immune system must of course also be inhibited. For this purpose, medications prescribed for the specific disease are used. Think of Neoral, MTX, Enbrel, Prednisone, and so on. In that case, be well informed about how you can combine medications to effectively treat inflammation in the body and in the eye.
