This progressive opticneuropathyis characterized by geomorphological changes , such as the archeological site of the visual disk , which make decease of ganglion cells and axon of the optic face . The ganglion cubicle of the retina are the longest in neurotransmission between photoreceptors and the mentality .
Gradually the ocular field and other functional changes such as color percept and direct contrast or movement will be affected . This summons is associated with the blockage of the trabecular meshwork that drain the aqueous humor and stimulate the intraocular pressure to uprise .
The mechanism that stimulate the harm of the optical nerve lie in an increase of the intraocular pressure , which is explain by the mechanical hypothesis , in which the space between the sheets through , which the axons of the optical heart pass make imperativeness provoking the progressive death of them and/or the affectation of the systemic circulation , cause ischemia in the vessels that irrigate the axons .
Do You Go Blind If You Have Glaucoma?
Glaucoma encompasses a family of continuing opthalmic neuropathies characterized by induce damage at the level of the optic face , causing the reformist exit of the vision subject . The absence of a uniform definition makes it difficult to deal the impact on global health . The World Health Organization ( WHO ) estimate that glaucoma is creditworthy for 10 % of blind mass in the world .
In 2010 , WHO register 4.5 million unsighted people due to glaucoma and 60.5 million people sham by the disease – It is the 2nd drive of sightlessness in the world and the leading cause of irreversible cecity .
In 2020 , 80 million people affected by the disease are expected .
The current treatments are pharmacological and surgical interventions for decreasing the intraocular press . The development and benefits necessary to better understand and , of course of study , to be able to cope with this pathology is circumscribed .
for understand the pathology from its starting time at the physiologic , morphologic and functional point , as well as its progression to a state of ocular impairment or blindness , it is necessary to present the disease from the beginning and have an legal action dodge consort to the pathology as a whole .
Glaucoma is not a purely medical issue , but for its backlash and prevalence , is also a social issue . It is a continuing and progressive disease with involvement in the ocular system , main sensory organization in which the human being is based for its motor , perceptive and cognitive development . It is not an isolated system , therefore , it must be borne in creative thinker that the principal moment , as it is an illness associated with long time , entail an modification and change in the twenty-four hour period by day of those affected .
optical renewal play an important part in advertise the autonomy and self - respect of these hoi polloi . It is not a disease that involve only the someone who suffers , but also the environment that coexists , physically and emotionally .
The result of the perform enquiry provide a reference book for the current clinical management , since they suppose a scientific evidence of the strength and safety of the treatment in reducing the progression and risk of blindness in the initial leg of the disease . Especially inferring the motivation for former diagnosing , where treatments are more effective . As it is an asymptomatic summons , it is usually name in advanced degree . Therefore , if we do not have beneficial access to health services that serve as a “ cover ” for the population or due to the want of social cognisance of the job of visual damage , we are facing a society that is more and more aging and at risk of suffering pathologies such as glaucoma , public health problem that affects either the most highly-developed country , or the least developed .
