Before considering getting cataracts removed, you should determine if the following methods can counteract vision problems:
1. New Glasses - Ask your ophthalmologist for new Bifocal Vision or Farsight Glasses to help you gain better vision. Try a magnifying glass for certain activities, such as needlework.
2. Reduce dazzling light sources - Enhance lighting at home by directing light sources directly onto objects or work surfaces. Adjust your light sources so that they are not dazzled.
3. Ask your ophthalmologist or optician for yellow-tinted lenses.
4. Eye Drops - Some types of cataracts can achieve better light transmission through drugs that dilate the pupils.
Glaucoma is a disease of the eye optic nerve. It is generally associated with high intraocular pressure. You must be attentive to your vision because glaucoma often leaves people without sight, as if not diagnosed in time, it may cause irreversible loss of vision. Optic nerve transmit data of visual type to our brain.
The front part of the eye has fluid that is constantly produced and flows out, maintaining a constant pressure. If the liquid can not flow out because its exit is blocked, the eyeball tension will increase and cause glaucoma.
The common case is primary or chronic open-angle glaucoma, with 2/3 of cases. This occurs when there is an open drainage area where the liquid exits from the eye, but it is not functioning well and the eyeball tension increases. Sometimes drainage hole become narrow and close gradually, it is the chronic type of closure. If the drainage angle is suddenly closed it is the acute type of closure.
Glaucoma with acute closure of the eye`s angle causes severe sudden eyeball pressure rise and is typically painful with the development of redness. Vision is blurred, you can see halos around bright spots of light. This type of disease may cause a strong sudden pressure increase, as a rule, with the development of painful redness. The vision is blurred, and you can see the halo. Congenital glaucoma can be detected by parents. The children of small age have easily expandable sclera of the eye, so that the eye tension increases with an increase of intraocular pressure. Gaps appear in the corneal endothelium, what leads to edema or swelling of the cornea, which produces a misty, frosted glass view. As corneal stretching, ruptures allow more liquid to fall into corneal stroma and epithelium, which leads to a sharp increase in edema and haze, increased lacrimation and photophobia. The child may become irritable and hide his head in the pillow to avoid the pain caused by bright light.
Glaucoma with narrow eye`s angle - is the anatomical form of the eye, which sometimes leads to high eye tension that can cause glaucoma. When the aqueous solution is discharged with approximately the same rate at which is made, it supports the normal eyeball pressure. If this water solution may not run as fast as it is produced, the pressure in the eye increases. This can occur if the opening is too narrow.
The harmed optic eye´s nerve without increased eye´s pressure is known as "low pressure glaucoma".
Elevated pressure in the eye does not give out until it becomes increased, with this type of disease, most people do not know that they have it.
Besides that symptoms of glaucoma it may include nausea, headaches. Chronic type of closure cause a gradual pressure.
Open glaucoma is the same that chronic glaucoma, and is a most frequent form of this disease. Glaucoma can be treated with surgery or lasers and medication. Eye drops also are commonly used in treating glaucoma.
Acute type of angle eye´s closure is a less common form of this disease that occurs when the draining function of eye does not work properly, liquid does not pass because of the small opening of the eye. This is accompanied by the following: the angle is blocked but fluid is accumulated inside with no possibility to get out of the eye that arise pressure in the eye and harms it. The general treatment in this case is a glaucoma surgery - a small part of Iris is removed that gives the possibility to liquid movement. Typical symptoms of this type are pain in eye, halos, distorted vision, headache and nausea.
The treatment of this type of disease is always surgical. It generally has success, but you may need not one but several operations. The glaucoma prognosis is not so good for disease detected at birth.
Not all cases of narrow angles need urgent treatment, the doctor will tell you what precautionary measures you should take and decide the treatment time. During this treatment a small hole will be made in the iris, this is a laser therapy or iridotomy. After the water can flow through the hole made by the laser, it may open the angle. This reduces the pressure inside the eye and thus protects it from damage.
Laser method is a stationary medical procedure. The procedure itself takes just 5-10 minutes, but you spend in the clinic something more than two hours in total, because it is necessary to check your pressure of the eye 1 hour after the end of the procedure. Risks of this method include some inflammation, increased intraocular pressure, blurred vision, bleeding and rarely visual distortion and glare. You should know that narrow angle glaucoma laser surgery does not imply any king of activity after it.
You can make glaucoma test and complete eye exam in German clinic that has all necessary modern medical equipment.
Typical eye exams consists of screening for glaucoma with tonometer. This machine measures the pressure in the eye. Another way to test your eyes for glaucoma is screening with modern imaging technology. Also is used common visual field test that allows to make diagnosis of peripheral vision.
It is necessary to make test of eyes time to time because some forms of this disease, like chronic type, does not give out itself by any symptoms. This disease can cause optic nerve harm. The optic harm is irreversible.
