The reason why glaucoma is considered a dreaded disease of the eye is mainly because of its hidden appearance and symptom free presence. It often comes without warning in most cases and when it actually appears to give some faint symptoms later on then the matter becomes too late and the patient in most cases progressively lose their eyesight for good. Glaucoma is seen to be inherited in most cases and is often associated with build up pressure in the eyes. Although it may have been present in a person during his or her early life, its symptoms are seen only late in life. Most patients affected by the disease are above the age of 40 years although it has been seen in children and adolescents too.
Causes and symptoms
The exact causes of the disease is not yet known although hereditary factors do contribute heavily especially in family history where there are more than one case seen. You may also find glaucoma causes associated with physical injuries in the eye or due to chemicals. These may be uncommon yet they too are reasons for the eye’s optic nerve to get injured.
Other uncommon factors are blocking of blood supplies to the eyes or due to eye surgery done for some other vision problem. Although the disease is seen to affect both eyes they may however be at varying degrees. If you have crossed the age of 40 and have a family history of such cases then you may go and check up your eyes every year or every two years.
The symptoms appear in some patients while for the majority there are no symptoms which mean that you need to go to your doctor regularly for eye examination. The first sign of the disease is generally loss of your peripheral vision or side vision. If you experience sudden eye pain or headache or experience blurred vision then you may perhaps be having glaucoma symptoms which again need to be established by visit to an ophthalmologist.
Some people see halos around any light source while others experience vision loss, redness of eyes or nausea or vomiting sensation. Towards the progressive stage most patients report tunnel vision.
Treatment for the disease
Glaucoma has to be treated at the very early stage or usually it is too late as patients may go blind. There are of course prescription drugs like eye drops that may reduce the formation of fluids in front of the eye or increase its outflow. Your doctor may also suggest laser surgery or microsurgery. This is done only after a comprehensive testing is carried out and the progress of the disease is analyzed.
It is usually seen that some well proven eye exercises and better dietary components may go a long way in preventing the disease. It is seen that glaucoma treatment is only a later process where the chances of cure is quite difficult as the same may have become quite serious. Hence, taking care of your eyes at early stage is your best chance of success.
