In general, vision problems can greatly affect the affected person regardless of their cause. A person who has this kind of problem can be very affected, weakened, and sometimes needs to be treated very quickly ...
There are different types of vision disorders, they can manifest themselves in various forms, for example:
- sparks or "lightning" in front of the eyes,
- dazzling, or flying flies
- fuzzy, distorted or disturbed images,
- black veil before the eyes,
- double vision,
- loss of part of the field of view,
- tubular vision (tunnel gaze).
Vision problems may occur temporarily or, on the contrary, prolonged. They may be innocuous - for example in a healthy person, a low blood sugar (hypoglycaemia) can temporarily cause flickering that will disappear then alone, immediately corrected problem.
But some eye disorders persist and require the intervention of an ophthalmologist, or even other doctors depending on the origin of the problem
Visual disturbances such as flickers can also occur during - or shortly before a migraine attack. In these cases, the symptoms usually disappear with migraine.
- To read: Migraine with aura
Depending on their causes, vision problems may be accompanied by other symptoms, for example:
- chewing problems ...
Some problems can cause persistent vision problems (eg retinal detachment), blood circulation problems in the eye or brain, such as stroke. These disorders require rapid support.
Occasionally, certain visual disturbances (localized pains in the eye, headaches, red eye, loss of visual acuity) occurring suddenly must be treated as quickly. This may be acute hyperpressure in the eye (acute glaucoma).
In case of persistent visual disorders whose origin is unknown, it is advisable to consult a doctor to identify the cause of these disorders and set up a treatment, a suitable solution. It is not mandatory to want to consult at any cost an ophthalmologist, because for some disorders, the general practitioner can already sometimes guide the diagnosis.
The need - and the choice - of the treatment depends on the cause of the disorders of vision:
- In the case of a simple hypoglycemia for example, it is generally enough to eat a piece of sugar (glucose) or to drink a sweet juice.
- In case of migraine, drug treatment can be effective.
- In case of myopia or hyperopia, corrective lenses are of course indicated, for example glasses.
- If visual disturbances are due to diseases such as retinal detachment or cataracts, surgery may be necessary to treat the problem.
