The accompanying symptoms

Depending on the underlying disease, the symptoms can be quite different. If there is an inflammation of the optic nerve, blurred vision occurs. This may be accompanied by headaches and a feeling of pressure in the eyeball.

Visual disturbances in the form of flashes of light or zigzag lines can occur in migraine. Other symptoms of migraine are fatigue, sleeping problems, nausea and vomiting.Paralysis and sensitivity to noise can also occur. In the presence of multiple sclerosis, the symptoms vary greatly.

Sensitivity disorders, paralysis, depressive moods, headaches or concentration problems can occur. The symptoms are therefore dependent on the area of the brain that is damaged, since each area of the brain fulfils a different task. In case of an eye disease, such as an inflammation of the eye skin or retina, there is a redness, increased lacrimation and a foreign body sensation in the eye.

In addition, visual acuity is reduced. If the photophobia is caused by mental illness, the accompanying symptoms are also variable. Sleeping problems, concentration problems and headaches can occur.

Blurred vision is a symptom that is often accompanied by light sensitivity of the eye. The cause of this is irritation or damage to the optic nerve. Normally, the optic nerve perceives incoming light stimuli and transmits them to the brain for information processing.

However, if the nerve is irritated by an inflammation, such as in retrobulbar neuritis or inflammation of the choroid, this process can no longer proceed properly. The light stimuli are perceived more strongly and cause pain. In addition, the surrounding area can no longer be seen sharply, as a misregulation occurs.

However, it is not clear how exactly this dysregulation occurs. Damage to the optic nerve, as is the case with multiple sclerosis, also leads to blurred vision. However, there is a risk of blindness due to severe damage to the nerve.

For this reason, it is important to consult a physician in case of light sensitivity and blurred vision, so that the disease can be clarified. Headaches also occur frequently as an accompanying symptom. Especially neurological diseases can cause headaches.

The best known disease in this context is migraine. Affected persons complain of attacks of unilateral headaches, which are particularly severe. Furthermore, infectious diseases such as meningitis, i.e. inflammation of the meninges, can cause severe headaches.

The meninges (meninges) are supplied by numerous nerves. These can be irritated by the inflammatory reaction triggered by the infection and cause severe pain. Comparatively mild headaches can be caused by retrobulbar neuritis, an inflammation of the optic nerve.
