It is the effect of the nerve that carries visual signals from the eye to the brain by an inflammatory process. It is a condition that is usually seen at a young age. The most important symptom is vision loss, one eye is affected, and eye movements may be painful for a day or two. Vision in the affected eye can occur in the form of slightly blurred vision, inability to see part of the visual field, or severe vision loss. Blurred vision after a hot shower or after sports can be a symptom of optic neuritis. Persistently washing your eyes with the feeling that there is something in front of your eyes is a common form of behavior. Along with visual acuity, color vision also deteriorates. Patients cannot read colored texts and cannot distinguish colors. Patients can contact an ophthalmologist thinking that their eye numbers are progressing, this type of vision loss does not improve with glasses.
When there is optic neuritis, edema( swelling) occurs in the affected area. If the affected area is close to the retina, swelling in the optic disc can be seen by the doctor. In optic neuritis that occurs in the more distant parts of the optic nerve to the eye after leaving the eye, a bottom-of-the-eye examination may be found to be normal. An MRI taken by special methods can show the state of inflammation and inflammation in the optic nerve.
Neuro-imaging and blood tests may be required for detection of the underlying disease and differential diagnosis. Multiple Sclerosis (MS) is the most common disease that leads to optic neuritis. In 15% of MS patients, the disease begins with optic neuritis, and more than half of them experience optic nerve involvement later in the disease. Autoimmune diseases, the cause of which cannot be determined other than MS, infectious diseases such as tuberculosis, and optic neuritis attacks due to some vaccines may develop. In the vast majority of patients, the underlying cause cannot be determined. This group is called idiopathic optic neuritis. After optric neuritis, vision loss begins to improve within weeks. Depending on the severity of the eclipse, it will improve almost completely within 6 months-1 year. Diagnosis and treatment at an early stage contribute to faster recovery of vision loss.
