Glaucoma: One of the major causes of blindness in the world


There are in excess of two million glaucoma patients in Pakistan and almost fifty percent of them have already lost their eyesight forever, owing to hold up in diagnosis and cure. This was revealed in an awareness session held at Al-Shifa Trust Eye Hospital. Many patients are suffering from this disease when it has ahead of time reached critical stage. The government should introduce on a large scale glaucoma screening programs for rescuing people of rural and distant areas from glaucoma and other eye maladies. Patients of continuous headache, eye stress, blood pressure and diabetes should give more consideration to their eyes. It is relevant to point out that glaucoma is the second foremost cause of blindness worldwide. Early identification and cure of the disease can avoid permanent vision loss causing from it however incorrect diagnosis of this possibly blinding condition based on simple mistrust can reveal a person to side effects related to treatment as well as mental strain to him and his family. Disclosure and cure of glaucoma consequently demands a cautious record taking, exhaustive clinical appraisal and use of proper diagnostic tests.
Al-Shifa Trust Eye Hospital has a fully operational and devoted glaucoma clinic where consultations are done four days a week while two days are placed for surgeries. In excess of 10,000 patients are recorded in the clinic which includes both the glaucoma cases and glaucoma distrust. Unluckily there were no distinct symptoms of glaucoma and many patients find them are in distress from this disease when it had a head of time reached forward stage. The government must initiate vast scale glaucoma screening programmes for saving people of villages and distant areas from glaucoma and other eye diseases.
Glaucoma from time to time is caused by an unusual increase of a clear fluid called aqueous humour inside the eyeball. Usually exhausted away and substituted by the eye, the fluid is critical for bringing nutrients to the lens and cornea and removing squandered material. It is one of the chief causes of blindness in the world. Vision loss due to glaucoma cannot be recovered. If glaucoma is acknowledged at an early stage, vision loss can be slackened or prevented. If there is the condition glaucoma, there is usually need for treatment for the rest of life. Glaucoma tends to in families. In some people, scientists have determined genes related to high eye pressure and optic nerve damage Open-angle glaucoma. Open-angle glaucoma is the most regular form of the disease. The drainage angle formed by the cornea and iris remains open, but the trabecular meshwork is partly blocked. This causes pressure in the eye to gradually increase. This stress destroys the optic nerve. It happens so gradually that you may surrender vision before even aware of a problem. When the iris bulges forward to narrow or block the drainage angle formed by the cornea and iris, Angle-closure glaucoma, also called closed-angle glaucoma occurs. As a result, fluid cannot circulate through the eye and pressure increases. Angle-closure glaucoma may occur suddenly (acute angle-closure glaucoma) or gradually (chronic angle-closure glaucoma). Acute angle glaucoma is a medical emergency. It can be activated due to the sudden enlargement of your pupils. Symptoms of Glaucoma are: Severe headache, pain in the eye, nausea and vomiting, blurry vision, halos around lights and redness of the eye. It is a set of eye conditions that damage the optic nerve, which is prerequisite to good vision. Sensitiveness to this disease depends on different factors including the level of pressure in the eye, a genetic tendency and older age.
March 16 is acknowledged as World Glaucoma Week. This is a week devoted to raising awareness of this neglected eye disease, also titled as the “silent thief of sight”. Some of the symptoms of glaucoma comprise the abrupt loss of vision, unclear and constricted eyesight, redness in the eyes, and serious headaches. Patients also report pain in the eyes and seeing rainbow-coloured circles in the presence of bright lights. Everywhere in the world an assumed 3million people endured from blindness due to not treated glaucoma in 2015, while another 4million accomplished to severe vision damage. This figure is likely to rise to an astonishing 80million by 2020. As a result, doctors that everyone over the age of 30 or even 40 get their vision regularly examined, specifically if they have a of blood pressure, diabetes or headaches and eye strain. The cost of medication is pricey, which results in some people not taking their medicine, even if diagnosed. There are also frequent reports of shortages of medicine and the required eye drops in the market, which are not locally produced and have to be imported. This must be stopped in the diagnosis and treatment of a disease for which there is no cure.
