What is Glaucoma – What Causes Glaucoma (Simple Answer)


So what exactly is Glaucoma? and What causes it? Well in this video I’t going to be covering just that and more! So let’s…take a look! Hey guys welcome to Doctor Eye Health! I’m Dr. Joseph Allen and it’s my passion to help educate people all about the eyes Vision, and finding the best vision products So if you’re new here, consider SUBSCRIBING Also check out the show notes below or further info about anything we mention Otherwise let’s go over “What is Glaucoma” So glaucoma is a condition or a disease where the optic nerve dies over time leading to vision loss and blindness Now lets stop and break that into pieces and make more sense out of it the optic nerve is the chord that connects the eye to the brain Light enters the eye, hits the retina and that information gets sent down the optic nerve to the visual processing centers, of your brain and that gives you your eyesight So if something causes damage to the nerve or the nerve dies and yeah…blindness sucks However, most cases of glaucoma are actually detected very early with comprehensive eye exams and treatment is excellent most people who get regular eye exams get glaucoma detected early on so that with treatments most people never go blind from glaucoma any more except there are some types of glaucoma that are very complicated and severe so even with the best treatments some people can lose vision and go blind from this condition now what most people think about when they see their eye doctor and they think about glaucoma they think EYE PRESSURE because there is this pressure test at any eye exam you will have where again we check the pressure and we are checking that to make sure the pressure isn’t too high and its true. HIGH EYE PRESSURE is associated with most types of Glaucoma However, not all of them You can actually develop glaucoma even with NORMAL EYE PRESSURES and we call that NORMAL TENSION GLAUCOMA And just a fun fact for today’s video a normal eye pressure for most people is between 10 and 21 millimeters of murcery now whether someone develops high eye pressures or normal tension glaucoma the treatment is really the same we either prescribe medicated eye drops or surgery to low that pressure down and for most people the treatment is really good however their are people where even if we bring that pressure really low they still advance and they lose vision and so early detection is really key when it comes to glaucoma so if you haven’t had an eye exam in the last year I really hope you can call you eye doctor and get seen just to make sure you are not developing this common disease so now “What Causes Glaucoma?” and honestly I don’t know, in fact its kind of still a medical mystery we don’t know the exact cause for glaucoma however there are many different theories out there and we do know that most types of glaucoma again are associated with that elevated eye pressure so lets at least go over what eye pressure is inside the eye and how it damages the nerve and causes glaucoma so within the eye there is actually a fluid it’s as clear fluid that acts like the blood of the eye it supplies energy and nutrients to the eye to keep it healthy and we call that fluid the AQUEOUS HUMOUR this aqueous humour is generated inside the eye by a structure called the ciliary body and the ciliary body is constantly generating this fluid all the time…every day and this fluid actually flows from the ciliary body behind the iris, it goes through the pupil and it actually drains through a structure called the ANGLE and that’s the junction created by the iris, the colored part of the eye, and the cornea, the clear window to the eye and if for some reason…this drain gets plugged up the ciliary body keeps producing aqueous humour and the pressure starts to get higher and higher and the problem with high eye pressure you can think of it like a bike tire filled with a lot of air if you keep pumping the air pressure higher and higher and the weakest part of the tire will eventually thin and bulge outward and if you keep pumping the air that bulge will eventually pop so the same concept happens with the eye. if the pressure keeps getting higher and higher the weakest part of the eye will bulge outward and the weakest part is the optic nerve. In fact, we call that optic nerve head cupping because when the doctor looks at the eye, it looks like a cup so when that happens the individual nerves that make up the optic nerve there’s about a million different fibers those fibers actually get pinched off and they eventually die and that’s what causes vision loss in fact the vision loss that starts with glaucoma usually develops so slowly… that people don’t even realize it’s happening until it’s too late until its already into the moderate stages of the disease now the type of vision loss, if you ever experience glaucoma and you experience the vision loss…it happens in your side vision your peripheral vision will slowly fade to dark and it usually starts in one quadrant sometimes forms an arc over the top of your vision it can then include the lower part of your vision and progresses to complete tunnel vision if it continues to progress without treatment it can even affect the central part of your vision until you have none left now although eye pressure plays a significant role it is not the only cause for glaucoma in fact the disease is associated with many risk factors such as genetics, age history of trauma and then other diseases like high blood pressure and even diabetes so now who is at the greatest risk for glaucoma? well the reality is that anybody can get glaucoma but people with a family history are more likely to get it so you have a grandma or grandpa who had glaucoma or a parent or a sibling make sure you let your doctor know because they are going to want to know that people of older age are also more likely so if your over the age of 60…your at a higher risk if you have any African or Hispanic heritage you are at higher risk now again age and risk go hand in hand for glaucoma but you can actually get the disease at any time even children can be born with glaucoma and we call that congenital glaucoma now the big take away I want from this video is that glaucoma can be detected early on and treated to prevent vision loss or at least delay it so its really important that you have an eye exam so if you haven’t had an eye exam this last year I hope that you can call your eye doctor and get seen Remember that you only get 2 eyes, so please take care of them!
