Reading at night can cause visual impairment

Sudden deterioration in vision

A sudden deterioration in vision always requires a quick clarification by the doctor. Often an inflammation or a disturbance of the blood circulation is the reason, an increase in intracranial pressure is also possible. An increase in intracranial pressure of unknown cause (Cerebral pseudotumor) occurs v. a. in younger, very overweight women. A similar clinical picture occurs as a result of a cerebral vein thrombosis and as a rare side effect of drugs, e.g. B. Lithium, antibiotics, vitamin A. In addition to chronic headaches, those affected mostly suffer from transient visual disturbances, ranging from visual field defects to complete loss of vision; Double vision is also common. Treatment includes weight normalization, diuretics, and punctures with drainage of cerebrospinal fluid. Without therapy there is a risk of permanent visual disturbances.

In the Retinal migraines The central retinal artery spasms causing a temporary loss of vision in one eye. In contrast to normal migraines, which can also lead to visual disturbances - albeit mostly bilateral - in the early stages, those affected usually do not suffer from headaches.
