GLAUCOMA GLAUCOMA Harold E Cross M.D., Ph.D (With contributions by T Altenbernd, MD, and P Tsai, MD) Brought to you by GLAUCOMA GLAUCOMA What is it? A disease of progressive optic neuropathy with loss of retinal neurons and their axons (nerve fiber layer) resulting in blindness if left untreated Brought to you by GLAUCOMA “Glaucoma describes a group of diseases that kill retinal ganglion cells.” “High IOP is the strongest known risk factor for glaucoma but it is neither necessary nor sufficient to induce the neuropathy.” Libby, RT, et al: Annu Rev Genomics Hum Genet 6: 15, 2005 Brought to you by GLAUCOMA GLAUCOMA What causes it? There is a dose-response relationship between intraocular pressure and the risk of damage to the visual field Brought to you by GLAUCOMA GLAUCOMA ADVANCED GLAUCOMA INTERVENTION STUDY Brought to you by GLAUCOMA GLAUCOMA How we diagnose it?     IOP is not helpful diagnostically until it reaches approximately 40 mm Hg at which level the likelihood of damage is significant Visual fields are also not helpful in the early stages of diagnosis because a considerable number of neurons must be lost before VF changes can be detected Optic nerve damage in the early stages is difficult or impossible to recognize 50% of people with glaucoma not know it! Brought to you by GLAUCOMA GLAUCOMA Intraocular pressure is not the only factor responsible for glaucoma!    95% of people with elevated IOP will never have the damage associated with glaucoma One-third of patients with glaucoma not have elevated IOP Most of the ocular findings that occur in people with glaucoma also occur in people without glaucoma Brought to you by CHARACTERISTICS OF IOP  Normal range: 10-22 mm Hg  Follows non-Gaussian curve with right skewed tail 30-50% of open angle glaucoma patients have IOP Brought to you by GLAUCOMA GLAUCOMA Treatment Medical Miotics  Beta-blockers  Carbonic anhydrase inhibitors  Prostaglandin analogues  Alpha-2 agonists  Surgical Argon laser trabeculoplasty  Trabeculectomy  Filtering procedure  Cyclocryotherapy  Cyclolaser ablation  Iridotomy  Brought to you by GLAUCOMA GLAUCOMA Treatment Brought to you by GLAUCOMA GLAUCOMA Surgical treatment of glaucoma Argon laser trabeculoplasty Filtration procedures Brought to you by GLAUCOMA GLAUCOMA Filtration blebs Brought to you by This platform has been started by Parveen Kumar Chadha with the vision that nobody should suffer the way he has suffered because of lack and improper healthcare facilities in India We need lots of funds manpower etc to make this vision a reality please contact us Join us as a member for a noble cause Brought to you by Our views have increased the mark of the 25,000  Thank you viewers  Looking forward for franchise, collaboration, partners Brought to you by Brought to you by Contact ,011-41425180 :-Us ,011-25464531 011-66217387 91-+,91-9818308353 + 9818569476 othermotherindia@g mail.com www.other-mother.in Saxbee Consultants Details https://cparveen.wix.com/other-mother :-www.parveenchadha.com https://twitter.com/othermotherindi http://www.linkedin.com/profile/view?id=326103341&trk=nav_responsive_tab_profile https://www.facebook.com/pages/Other-Mother-Nursing-Crusade/224235031114989?ref=hl A WORLDWIDE MISSITION JOIN US THANK YOU ALL FOR LISTENING! ...
