When it comes to vision loss, Hemianopia is one of the conditions that can result in it. It can bring a significant change in the lifestyle of any person. Hemianopia can be the result of different factors and in this article will look at some basic information about this condition.
What is Hemianopia?
Hemianopia is a condition which results in the loss of visual field in your eyes. Its severity and the other symptoms you experience can vary widely, depending on the seriousness of the condition and its causes.
This condition can affect either one or both of your eyes. When both eyes suffer from Hemianopia, the affected vision fields can be the same or different in each eye.
This condition, however, does not mean that there is something directly wrong with your eyes, but instead those issues can appear when the brain or the optic nerve are affected. This impairs the ability of the brain or the optic nerve, to relay or process properly the images received from the eye.
What are the causes of Hemianopia?
Hemianopia is often the result of other conditions which affect the vision processing parts of the brain or conditions that affect the optic nerve. It could also occur due to trauma, which results in damaging those areas of the brain.
Some of these causes include:
- Multiple sclerosis and more
A number of those conditions can be prevented to a degree by having a healthy lifestyle, by avoiding smoking, drinking and eating healthier food.
What are the symptoms of Hemianopia?
Missing vision fields can be one of the signs that you have suffered from Hemianopia. This, however, is hardly the only symptom that you may experience. Other such symptoms come in the for of:
- Double vision
- Blurred vision
- Poor night vision
How do you treat Hemianopia?
There are no specific treatments which can help improve your eyesight after suffering a Hemianopia. In some instances the condition can get better over time, but there is also the possibility that the impairment will remain permanent. Your doctor will be able to offer various approaches to treating and improving your vision. Normally the improvements occur in the first one to two weeks after suffering a hemianopia, otherwise readjusting would be necessary.
There are speculations that it is possible to restore partially the affected functions with rehabilitation. There is a possibility that some of the vision field can be restored, when undergoing therapy to improve vision processing.
People who have experienced Hemianopia will benefit from various re-adjustments to their new lifestyle. Reading and driving are tasks which would be much harder now and optimising your remaining vision toward achieving those goals is one of the options.
Some vision aids can prove beneficial, like hemianopic spectacles or prisms, even though they have not found a wide application. They are meant to improve vision by reflecting light towards the working part of the vision field.
Hemianopia can impact the life of an individual significantly, so support and helping them adapt to their new lifestyles might be among the best ways to help them.
