Why glaucoma(موتیہ کالا) is dangerous.

 Glaucoma is a multi-factorial disease that affects our vision slowly in the matter of months and years if not days. The eye of the patients looks perfectly fine from the outside but the inside of the eye is getting damaged. Retina which is the inner most layer of the eyeball is most prone to damage. The most common factor being the raised intraocular pressure. Intraocular pressure can be raised due to obstruction of the watery fluid from the inside of the eye where it is continuously being produced. This raised intraocular pressure compresses the micro fibers of the retina and thus decreasing the peripheral field of the vision. Retinal fibers that are involved in the straight ahead vision are not affected until the disease has progressed to its most severe form after which the person becomes permanently blind. This comes to the patient out of the blue that he is blind all of a sudden. So it is necessary that when ever you go an ophthalmologist for your gross vision assessment, you ask your ophthalmologist to check your optic disc because some forms of mild if not early glaucoma can be diagnosed by the checking the optic disc.
