Took my dog to the vet for an eye infection. A week later turns out she has glaucoma. <\/p>\n<p>Today, just came back from the ophthalmologist, good news her pressure went from 55 to 32. Still need to bring that down but we will. Turns out my 5 year old Bella is now blind in her right eye. I was told by the ophthalmologist that this common in Shiba Inu\u2019s.<\/p>\n<p>Once they get it in the one eye, Bella is predisposed to getting it in they other eye. We are doing preventative measures now. But GET YOUR SHIBA\u2019S EYE PRESSURE TESTED. I haven&#8217;t stopped crying since I got home. My biggest fear, what do I do if she goes blind in the other eye? <\/p>\n<p>Get your doggies tested!!!!!<\/p>\n<\/blockquote>\n<p><strong>** NOTE &#8211; I am not a vet so all the information in this article is based on my readings on the internet and chats with other dog owners.<\/strong><\/p>\n<div class=\"alignspace\"><\/div>\n<h2>What is Glaucoma?<\/h2>\n<p>As I understand it, Glaucoma is a condition of the eye where the optic nerve suffers damage as a result to increased fluid pressure inside the eye. <\/p>\n<p>In particular, there is a fluid called <a href=\"http:\/\/en.wikipedia.org\/wiki\/Aqueous_humour\">aqueous humour<\/a> between the cornea and the lens of the eye. This fluid is constantly produced and is normally drained out into the bloodstream through the drainage angle (<em>Iridocorneal angle<\/em>).<\/p>\n<p>Problems occur when the drainage is obstructed, thereby cause a buildup of fluid and therefore pressure in the eye.<\/p>\n<p>If left untreated, this could lead to permanent damage of the optic nerve and may even lead to blindness.<\/p>\n<div id='2855' class='wp-caption frame3 aligncenter' style='width:520px' ><div class='shiba-outer shiba-gallery' ><div class='shiba-stage' style='width:520px'><img loading=\"lazy\" src=\"https:\/\/shibashake.com\/dog\/wp-content\/uploads\/2010\/03\/IMG_1239-520x390.jpg\" alt=\"Siberian Husky Shania has very beautiful eyes.\" title=\"Siberian Husky Puppy Shania Face Close-Up\" width=\"520\" height=\"390\" class=\"size-large wp-image-2855\" \/><div class='wp-caption-text shiba-caption'>Siberian Husky Shania has very beautiful eyes.<\/div><\/div> <!-- End shiba-stage --><\/div><\/div>\n<div class=\"alignspace\"><\/div>\n<h2>Dogs and Glaucoma &#8211; Should We Be Concerned?<\/h2>\n<p>In general, there are two types of dog glaucoma &#8211;<\/p>\n<ul>\n<li><strong>Primary glaucoma<\/strong> is hereditary. Dog breeds specifically mentioned include &#8211;<br \/>\n<blockquote>\n<p>Primary glaucoma occurs in many breeds of dogs, including the American Cocker Spaniel, Basset Hound, Chow Chow, Shar Pei, Jack Russell Terrier, Shih Tzu, and Arctic Circle breeds (including the Siberian Husky and Elkhound). Primary glaucoma is rare in cats.<br \/>\n~~[<em><a href=\"http:\/\/animaleyecare.net\/diseases\/glaucoma.htm\">Animal Eye Care LLC<\/a><\/em>]\n<\/p>\n<\/blockquote>\n<p>This is likely not a complete list. Dakota mentioned in her comment that Shiba Inus may also be susceptible. Since I have a Shiba and two Sibes, I am definitely concerned.<\/p>\n<p>The key problem with primary glaucoma is that the symptoms are usually mild and may not be easily observable, even by a regular vet. By the time that it is detected, it could already be too late, and there could already be permanent damage to the optic nerve.\n<\/li>\n<li><strong>Secondary Glaucoma<\/strong> usually occurs as a result of some other kind of eye disease such as inflammation in the eye (uveitis) or advanced cataracts. Since the dog is under vet care for the initial eye disease, this type of glaucoma is more easily detectable. Presumable we can also perform an eye pressure measurement test after our dog has recovered from the initial eye problem.<\/li>\n<\/ul>\n<div id='4308' class='wp-caption frame3 aligncenter' style='width:520px' ><div class='shiba-outer shiba-gallery' ><div class='shiba-stage' style='width:520px'><img loading=\"lazy\" src=\"https:\/\/shibashake.com\/dog\/wp-content\/uploads\/2010\/06\/siberian-close-up-520x390.jpg\" alt=\"Siberian Huskies are listed as one of the breeds susceptible to hereditary glaucoma (primary glaucoma).\" title=\"Siberian close-up\" width=\"520\" height=\"390\" class=\"size-large wp-image-4308\" \/><div class='wp-caption-text shiba-caption'>Siberian Huskies are listed as one of the breeds susceptible to hereditary glaucoma (primary glaucoma).<\/div><\/div> <!-- End shiba-stage --><\/div><\/div>\n<div class=\"alignspace\"><\/div>\n<h2>Detecting Glaucoma in Our Dogs<\/h2>\n<p>The first thing that I did after looking up dog glaucoma is to contact my Siberian Husky breeder. I asked her if she has experienced glaucoma before with her Sibes.<\/p>\n<p>Since the less detectable type of glaucoma, (Primary Glaucoma) is hereditary, I wanted to check the family tree of my two Sibes. If their family tree is free of glaucoma, then they are probably less at risk of inheriting it. <\/p>\n<p>My Sibe breeder tells me that none of her Huskies have gotten glaucoma before. Her mom&#8217;s Basenji had glaucoma, but that was a secondary effect from having cataracts when she was 14 years of age. My breeder also tells me that the Basenji had a lot of tearing (tears) before being diagnosed with glaucoma.<\/p>\n<p>According to this <a href=\"http:\/\/www.blinddogs.com\/articles\/glaucoma.htm\">very useful article on glaucoma in Samoyeds<\/a>,<\/p>\n<blockquote>\n<p>The early signs of glaucoma, which may not be recognized as such, may consist of mild conjunctival inflammation, which can mimic conjunctivitis; increased tearing and pain; and photophobia (sensitivity to light which results in some &#8220;squinting&#8221; of the eye).<\/p>\n<\/blockquote>\n<p>My Shiba Inu&#8217;s breeder is not all that great and was uninterested in keeping contact with Sephy. I may get my vet to do an eye pressure test on him during his yearly exam.<\/p>\n<div class=\"alignspace\"><\/div>\n<h2>Testing and Treatment for Glaucoma in Dogs<\/h2>\n<p><strong>For the testing and treatment of dog glaucoma, it is best to consult with your vet or with a veterinary ophthalmologist.<\/strong><\/p>\n<p>Based on what I have read, there are two different glaucoma tests for dogs &#8211;<\/p>\n<ul>\n<li><strong>Tonometry<\/strong> &#8211; This is the simpler test that measures intraocular pressure (IOP). Supposedly, more vets are equipped to do this and it can be performed with just a topical anesthetic. <\/li>\n<li><strong>Gonioscopy<\/strong> &#8211; This is a more invasive test that is used when primary glaucoma is already present in one eye. This test examines the drainage angle of the remaining visual eye to see if it is also predisposed to glaucoma. It seems that this test is mostly performed by a veterinary ophthalmologist.<\/li>\n<\/ul>\n<p>According to <a href=\"http:\/\/animaleyecare.net\/diseases\/glaucoma.htm\">Animal Eyecare LLC<\/a>, there are three classes of treatment for dog glaucoma &#8211;<\/p>\n<ul>\n<li><strong>Glaucoma Eye Drops<\/strong> &#8211; These eye drops help to decrease fluid production and increase fluid drainage. Apparently, it is a short term solution and is not very effective at controlling glaucoma in the long term.<\/li>\n<li><strong>Antioxidant Vision Supplements<\/strong> &#8211; These supplements can apparently help to reduce oxidative damage to the cells in the eye that are responsible for fluid drainage. It is also not a good long-term solution for dogs that already have glaucoma.\n<\/li>\n<li><strong>Surgery<\/strong> &#8211; It is best to consult with an eye specialist for the list of possible surgical procedures. <\/li>\n<\/ul>\n<blockquote>\n<p>Dogs with glaucoma or at risk of developing glaucoma should have leashes attached to harnesses and not neck collars, to prevent pressure on the jugular veins (which can in turn increase IOP and trigger a glaucoma attack).<br \/>\n~~[<a href=\"http:\/\/animaleyecare.net\/diseases\/glaucoma.htm\">Animal Eye Care LLC<\/a>]\n<\/p>\n<\/blockquote>\n<p>If you have experienced glaucoma with your dogs, please share your stories with us.
