What is Glaucoma
Glaucoma is an eye disease that can cause impaired vision and even blindness. It is caused when the pressure of the normal fluid inside the eyes increases slowly. The increased normal fluid pressure in the eyes damages the optic nerve of the eye which in turn causes vision loss and blindness. Optic nerve joins the retina to the brain so for a good vision, healthy optic nerve is essential. It is a serious disease and can have very serious results if not treated properly. For a good and effective treatment, it has to be diagnosed at an earlier stage. Glaucoma has no symptoms at an earlier stage, this is why; it is left untreated and cause complications. Very few people are aware of the fact they have developed glaucoma at an earlier stage. It is very difficult to diagnose it at an earlier stage and gradually the person lost his vision.

If the immediate treatment will not be given to the patient, then it can cause blindness in one or two days of the attack.
As earlier mentioned, glaucoma should be diagnosed as soon as possible to avoid the further damage of eyes. Glaucoma can be diagnosed by various exams like tonometry, fundus examination and perimetry. The main aim of this examination is to check the level of the damage caused to the eyes and to check the present condition of the eyes. The treatment will be given according to these exams and their results. The main aim of the treatment is to control the normal fluid pressure of the eyes. Eye drops and oral medications can be prescribed to control the pressure. The medications should be taken at regular intervals and the patient should strictly follow the instructions of the doctors. The patient should go for the exam regularly. The condition should not be taken as granted. Sometimes, surgery is the only option to cure glaucoma.
