GlaucomaGlaucoma is a condition that results in vision loss and in severe cases leads to blindness. It is a group of diseases that affect the optic nerve that is responsible for transmitting and processing visual stimulation that is interpreted as sight.  

How it occurs 

The eye maintains a constant level of fluid pressure in the eyes. This fluid is produced in the area behind the iris called the anterior chamber and is responsible for rinsing and nourishing nearby tissues. Its constant stream needs to be maintained such that drainage is kept under control.  

Poor drainage results in pressure build up that in turn harms the optic nerves. 

Causes 

Blood pressure is a contributing factor that leads to glaucoma and the disorder has been known to be genetic. It may occur at a later stage in life. 

Trauma to the drainage angle may bring about this condition. Chemical damage to the eye also increases the risk factor. 

Signs and symptoms 

Severe eye pain accompanied by blurred vision may indicate a stage in glaucoma. Other symptoms are sudden vision problems in areas where there is poor lighting. 

A halo ring appearing around a light source is a possible indicator of harboring the condition 

Risk factors associated with glaucoma 

Old age is a contributing factor with people above 60 years being more prone as a group. 

Eye surgery in the past has been identified as a probable cause that may be a key factor that spurs its occurrence.

People that have been diagnosed with diabetes are more likely to be at risk. 

Myopia (shortsightedness) is associated with a more likelihood to the disorder. 

Types

Open angle 

It is the most common type that occurs when fluid does not flow properly through the channel. It is hard to detect as all eye structures appear normal but the incidence is present. 

The ailment can be present in one or both eyes. Vision tends to decrease over time as the condition worsens to the point where no vision is present. 

Acute glaucoma 

This occurs when the drainage channel of the eye is too narrow. This results in a sudden eye pressure buildup that may cause a lot of discomfort. It is treated as a medical emergency as one may go blind if due treatment is not administered. 

An operation may be needed to create a new channel to offset the attack. 

Treatment for glaucoma

There is no treatment for lost vision. However, early diagnosis plays a crucial role in curbing advancement of the condition to an adverse stage that then causes vision problems and blindness. 

Consulting a physician at the very onset of symptoms is recommended for fast relief and for protection against further exacerbation. 

Laser treatment options are available to create a pathway for the liquid to escape. This eases the pressure by providing a release channel for the retained fluid. 

Prevention tips

A regular complete eye exam is a good precaution to make as it reveals any inherent issue that may be present. Early detection is crucial to stem any developments that may compromise visual acuity.
