Understanding Glaucoma And Its Symptoms
The optic nerve is perhaps one of the most vital components of human eyesight. As such, any injury or disease to this vital part of human eyesight can have serious consequences. In fact, the optic nerve as with any other nerve in the body is very slow to regenerate or will not regenerate at all once it has been damaged. That is why protecting and caring for this part of the eye is so essential. The optic never is literally a direct link between the eye and the brain, making vision possible.
Detecting and treating diseases and conditions that affect the optic never are vital to long-term eye health. One disease that can often go undetected and that can cause serious damage to the optic nerve is known as glaucoma. This disease is especially important to detect as early as possible because it typically causes irreversible damage to the optic nerve. Most notable about glaucoma is that it has virtually no symptoms. However, patients will report a reduction in peripheral vision in a gradual kind of way. Patients will eventually develop “tunnel” vision as a result.
Glaucoma causes optic nerve cells to die off at an accelerated rate. Interestingly, the nerves that are most vulnerable to this are the ones that are directly associated with peripheral vision. The most accepted indicator or risk factor related to the onset of glaucoma is high eye pressure as measured inside the eye. However, approximately 30% of patients dealing with glaucoma indicate normal eye pressure. As such, effective diagnosis and detection is considered to be rather challenging when it comes to glaucoma. New ways of detecting this disease will likely come to the forefront in the coming years.
Because it is this excess eye pressure that is the root of the problem with regard to glaucoma, the most effective way of dealing with this condition is to lower pressure within the eye. It is important to note that this is an accepted treatment even when normal eye pressure is indicated. From laser surgery to eye drops and invasive surgery, these are all considered viable options for treating glaucoma. Oral medication is used to offer treatment on rare occasions.
