Vision Disorders

It seems they can. I had a cataract replaced and before that I was near sighted. When I went to get my new contact, since my astigmatism was not fully corrected by the implanted lens, it was found after several examinations of not being able to fit me with the first prescription after the surgery that on a next exam my vision had done a 180 turn to farsighted. It went from a negative - to a + prescription and as of yet have not been able to fit me with a proper prescription

Cataract surgery and it's expensive so at least get one eye done. Dogs get cataracts just like people do. Border Collies can be prone to this disease. I live in Canada and friends of ours (live in Canada) have a Border Collie and had cataracts on both eyes. They could only afford to get one eye done and it was almost $3,000. You can speak with your vet and see if there is any way you can pay for a medical plan for your cat and then get the surgery done which will be a lot less. At least give the dog the sight of one eye.

There are many different types of Glaucoma, but I don't have time to tell you all of them, do I?

I'll tell you the two most common types though.

Two types of Glaucoma is "open angle" and "closed angle". Closed angle is when Glaucoma comes suddenly and painfully. Vision loss comes quickly and but the pain quickly leads those infected with it to medical help before the permanent damage is done. Open angle lets the glaucoma disease progress slowly and unpainfully. The person infected usually doesn't know they have vision loss until damage is permanent.

I HAVE NOT ONLY DISCOVERED THE PERFECT DIET AND NUTRITION FOR GLAUCOMA BUT I HAVE CURED MYSELF OF GLAUCOMA THROUGH MY DIETARY AND NUTRITION PLAN AND THIS CAN BE VERIFIED BY MY OPHTHALMOLOGIST AND I SUGGGEST YOU EMAIL ME AT ringollie@yahoo.ie REGARDS JAMES.

i'm asking u... not you asking me..

A Good optometrist will check for glaucoma in several ways. Family History Intra-ocular pressure: Non-contact tonometry or contact tonometry (better) Appearance of your optic nerve (preferably with a retinal photograph) Your visual field using automated perimetry, which maybe repeated several times. Other machines can be used which aim to measure the thickness of your nerve fibre layer through indirect measurements which can be useful for tracking nerve changes and glaucoma progression but cannot be used solely for diagnosis. It takes a combination of all these measures to diagnose glacuoma

Corneal crosslinking is a technique that uses ultraviolet light and riboflavin to prevent further steepening or thinning of the cornea. This surgical procedure is usually done where the epithelium at the front of the eye is removed prior to exposing the eye to ultraviolet light treatment.

Because corneal epithelium is removed, the patient will in essence have a corneal abrasion that can last anywhere from one week to even a couple of months. Healing times can vary per patient but expect discomfort during the period where the cornea has to recover from the surgical procedure. During the healing process, it is normal to have antibiotic coverage to prevent an eye infection. In addition, a bandage contact lens may be applied to improve comfort during the healing process.

The Fovea Centralis is a small pit located laterally to the optic disk and is the area of sharpest vision that is located in the center of the macula lutea.

Well, at first it does. The first day that you get them it will probably shock you as to how much clearer everything is and how messed up your vision was. When you walk around, the ground might look like it's closer and you might bump in to things because your closer to them then you think you are. You may also knock things over or reach for something and miss it because they are either closer or further away than they appear to be. Your brain will adjust to it in time and you will be able to grab things like you did before getting glasses. If you have astigmatism things may appear to be bent and this too will correct itself as your brain adjust to seeing things correctly. If your nearsighted things will appear to be smaller and if your farsighted it will appear to be larger, but again you will get used to it over time. You will also probably feel like you are looking through little windows and see the frames of your glasses in your field of view, but this too will disappear in time and it will eventually not feel like you are looking through glasses. Perhaps the thing that will feel the most weird will be wearing glasses around family and friends, you will be uncomfortable and probably self conscious at first, but each day will get easier and in time everyone will get used to seeing you in glasses and you will become more confident and comfortable wearing them. it takes time, but they will become a part of your life, you will put them on in the morning and take it off at night.

glaucoma makes you permanently blind.

Lenses can correct vision problems by bending light rays before they reach the eye, in effect moving the focal point of the eye's lens so that it falls upon the retina and creates a clear image. Concave lenses cause light rays to converge and lengthen the focal point for the near sighted eye. Concave lenses are thinner in the middle and thicker on the edges and may be curved on one or both sides. Concave lenses cause light rays to diverge, or spread apart. :)

Being diagnosed as being nearsighted means just exactly what it says. You can only focus on things close to you. Distant objects are out of focus. Being farsighted means just exactly the opposite of being nearsighted. Distant objects are in focus, but nearby things appear blurry.

No. Above drug should not be uesd if you have glaucoma.

Glaucoma can be acute or chronic and both have high intraocular pressure which is higher in acute than chronic. Chronic glaucoma is the most common type and the patient will not feel any thing until the disease is advanced with constriction in the peripheral visual field that increase gradually till the patient only see through the center of his vision. The acute type which is due to angle closure glaucoma comes with red eye, increase tearing, photophobia or light sensitivity, severe pain that radiate to the head causing headache, nausea, vomiting, blurring of vision due to corneal edema. Acute glaucoma is a medical emergency that should be treated as soon as possible.

You can either be born with glaucoma (congenital) and this can be the primary disease or a secondary one. In the case of it being secondary, it could for example be secondary as part of a rare condition called Axenfelds Anomoly, where the primary is about underdeveloped bones, usually jaws, and teeth can be missing as a result. Though in such a case glaucoma is the secondary part of the problem, it is the first to be diagnosed and is by far the more serious of the two.

Glaucoma can also be hereditary, this could apply to congenital glaucoma or otherwise.

The otherwise then would be developing glaucoma in old age. This is less serious than congenital glaucoma in that it is less aggressive and does not have to be treated for the persons entire life.

Diverging Lens are use (reading glasses) to help correct the problem of myopia helping fix the focus which causes items far away to seem fuzy and blurry.

The objective of glaucoma treatment is usually to decrease IOP. When glaucoma is diagnosed, drugs, typically given as eye drops, are usually tried before surgery.

Chronic glaucoma is a group of disorders that affect the eye. The most important cause is increased fluid pressure resulting from overly slow drainage of fluid.

Yes, you can generally take ibuprofen if you have glaucoma, but it's important to do so under the guidance of a healthcare provider. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that does not typically affect intraocular pressure, which is crucial for glaucoma management. However, individual health factors and medications can vary, so consulting with a doctor is recommended to ensure it’s safe for your specific situation.
