Glaucoma Eye Drops Treatment
Glaucoma eye drops are usually the preferred choice for the treatment of glaucoma patients over glaucoma eye surgery and they can be very effective at reducing elevated intraocular pressure (IOP) to help prevent optic nerve damage in glaucoma sufferers. If your doctor thinks that you are a good candidate for glaucoma eye drops, he may prescribe you more than one type of glaucoma eye drops to give the best intraocular pressure reduction. There are many different types of glaucoma eye drops and they can work in synergy; one type enhancing the effects of the other type.
Whether you are an ideal candidate for prescribed glaucoma eye drops treatment is largely dependent on your general state of health and whether you have any other medical conditions. This is due to the fact that prescribed medications put into your eyes get absorbed into the conjunctival blood vessels on the surface of the eye. Because of this, a very small amount of the active drugs in the drops will be absorbed into your bloodstream and this can adversely affect functions like your breathing and heart rate. Also, some types of glaucoma eye drops may worsen any existing medical conditions and especially asthma. Some glaucoma drugs can also adversely interact with other commonly prescribed drugs like digitalis which is commonly prescribed for bad heart conditions. Because of this, be sure that you discuss these things thoroughly with both your family health care professional as well as your eye doctor or ophthalmologist before commencing any glaucoma eye drops treatment.
Different Types of Glaucoma Eye Drops
Glaucoma eye drops are usually classified into different categories depending upon the main active drug within the drops that makes the drops work and the mechanism of their action. Many of the glaucoma eye drops listed below will also be available from your pharmacy or chemists shop in their generic form.
The group of drugs known as prostaglandins that are used in glaucoma eye drops only need to be applied once daily and so usually have the best patient compliance with their application. Prostaglandins mechanism of action is to relax the muscles inside the eye’s interior structure which then allows for a much better outflow of fluids from within the eye and thus reducing the buildup of eye pressure within the eye and therefore lowering the intraocular pressure.
All prostaglandins based drugs have a few common side effects which include the following; a darkening of the colour of the eye due to them increasing the pigmentation in the iris, a burning or stinging sensation, and also making eyelashes longer and more curly. Incidentally, this last phenomena later lead to the development of another drug called Latisse which is another prescription drug available now for lengthening eyelashes.
FDA Approved prostaglandins drugs include; Lumigan from Allergan, Xalatan from Pfizer, Rescula from Novartis and Travatan Z from Alcon. In recent years, many glaucoma eye drops specialists report that prostaglandins have taking a commanding lead as the main therapy for the treatment of glaucoma.
Beta-blockers are now used in a selection of different glaucoma eye drops and they were at one time the leading choice of glaucoma specialists for the treatment of glaucoma. Beta-blockers mechanism of action are to decrease the fluid (aqueous) production within the eye and are now often prescribed as an adjunct to, or to be used in conjuntion with, prostaglandins drops.
These drugs have more adverse side-effects including; diabetes, depression, lung conditions such as emphysema, the potential to reduce heart rate or other adverse conditions. Because of this, be sure that you discuss these things thoroughly with both your family health care professional as well as your eye doctor or ophthalmologist before commencing any glaucoma eye drops treatment.
Some of the most common Beta-blocker eye drops used in the treatment of glaucoma are Betoptic S from Alcon, Istalol from ISTA and Timoptic from Merck.
The Alpha-adrenergic agonists based drugs mechanism of action is to reduce the aqueous humour production rates and they can be used on their own or in conjunction with glaucoma eye drops.
FDA Approved drugs for the treatment of glaucoma in this class include; Alphagan from Allergan, Alphagan-P from Allergan and Iopidine from Alcon.
The most common adverse side-effects connected with the use of these drugs include; itching of the eyes, enlarged dilated pupils and elevation of the upper eye lid.
Carbonic anhydrase inhibitor (CAIs)
The carbonic anhydrase inhibitor based drugs mechanism of action is also to reduce the aqueous humour production rates and are usually used in conjunction with other glaucoma eye drops treatment and are not usually used just on their own. This call of drug can also be applied orally in the form of pills.
The most common adverse side-effects connected with the use of this class of drugs include; a burning or stinging sensation , eye redness (ocular injection), eyelid reactions and a bitter taste.
FDA Approved eye drops in this classification include; Aztopt from Alacon and Trusopt from Merk. The oral versions that comes as pills (systemic) include; Daranide from Merck, Sharp & Dohme, Neptazane from Wyeth-Ayerst and Diamox from Sigma.
Roughly fifty percent of people can’t tollerate taking these CAI’s due to their adverse systemic side-effects including; a metallic taste, loss of appetite, loss of libido, fatigue, depression, kidney stones, weight losss and a tingling sensation felt in the fingers and toes known as peripheral neuropathies.
The Parasympathomimetics calls of drugs mechanism of action is to increase the outflow of the aqueous humour from the inside of the eye. These glaucoma eye drops are often used in the cases of narrow-angle glaucoma patients to control their intraocular pressure. They cause the pupils to constrict which helps to open up the blocked or narrowed angle where the eye’s drainage system is.
The most common adverse side-effects from using these glaucoma eye drops include; reduced night vision, a burning sensation and brow ache.
FDA-approved drugs in this class include Demecarium from LaRoche, Pilocarpine from Bausch & Lomb, Carbachol from Pharma Fair and Echothiophate from Wyeth Pharms.
The epinephrine classification of glaucoma drugs has a dual mechanism of action upon the eyes. This class of drugs work by the combination of increasing the outflow of aqueous humour from within the eye whilst also reducing the rate at which the aqueous hour is produced by the eye.
The most common adverse side-effects with the use of this class of drugs include; an increased heart rate with heart palpitations, blocked tear ducts and deposits on the pigmented eye surface membrane called the conjunctival.
The FDA-approved drugs in this class of glaucoma eye drops include; Propine from Allergan (Dipivalyl epinephrine) and Epinephrine from Eastman Kodak.
Hyperosmotic Agents are usually administered on a one time only emergency basis to people with extremely high intraocular pressure that must be immediately reduced before permanent damage to the optic nerve has been done. These drugs mechanism of action is to quickly reduce intraocular pressure by reducing the volume of fluid inside the eye and include; Mannitol and Urea administered intravenously and glycerin and isosorbide administered orally.
Combination glaucoma drugs
Study results have shown that approximately fifty percent of glaucoma patients require more than one type of glaucoma medication to control their intraocular pressure levels. Because of this, some ophthalmic pharmaceutical companies are now manufacturing ‘combination’ glaucoma eye drops which include two different anti-glaucoma drugs inside the same bottle so that they are both administered at the same time.
For your convenience, your eye specialist or ophthalmologist may prescribe you these combined intraocular pressure lowering medications. These combined glaucoma treatment drugs typically have an additive effect, working together to reduce elevated intraocular pressure levels more than using each one on its own.
Some examples of combined glaucoma drugs approved by the FDA include; DuoTrav from Alcon, Combigan from Allergen and Cosopt from Merck.
A Revolutionary New Glaucoma Eye Drops Treatment
Now there is a brand new, drug-free, all natural alternative on the market which offers the same, or better results, with non of the adverse side effects associated with all of the prescribed medications listed above. NAC eye drops contain the all natural ingredient N-Acetyl-Carnosine which posesses the unique ability to rejuvenate and regenerate cells and is very effective at reducing intraocular pressure associated with glaucoma.
Even more interestingly, NAC works at a cellular level to repair the damage caused by glaucoma. All of the drugs listed above treat the symptoms of glaucoma and not the causes. The text books state that once the optic nerve has been damaged by glaucoma that damage is then irreversible. But new evidence suggests that the NAC in the new glaucoma eye drops actually starts to rejuvenate and regenerate the damaged optic nerve cells.
NAC is indigenous to the human body and so it is not a drug, vitamin or mineral. It is thought to be the body’s own repair substance and, when applied topically to the eyes by using NAC eye drops, it penetrates the cornea, into the aqueous humour below, and then circulates around the inside of the eye looking for damage to repair.
Michael Wildman, who was the gentleman featured on the Richard & Judy Show trials with me, got his wife to try our Glaucoma Eye Drops as he got such great results with our other drops for cataracts as she suffered with glaucoma. Prior to using Bright Eyes eye drops for glaucoma, she had used two different prescribed medications; Xalatan and one other, for over 2 years, with no signs of any improvements whatsoever. She was having six-monthly checkups and on her next checkup, after using Bright Eyes eye drops for glaucoma, her ophthalmologist was amazed to report that her intraocular pressure had dropped from 28 mm/hg to 14 mm/hg which is back within the normal range. Her eye specialist was so amazed at such great improvements since her last check up that he then sent her for further test with a specialist and those subsequent tests confirmed that her periphery vision had also improved as well which is virtually unheard of with glaucoma sufferers.
Everyone is at risk from glaucoma; from new born babies to the elderly alike. Even with standard prescribed medications and treatments intraocular pressure within the eyes may continue to escalate and glaucoma can continue to advance until ultimately the progression leads to complete blindness.
NAC glaucoma eye drops also have excellent prophylactic properties and should be used regularly to stop the onset of glaucoma and many other degenerative eye conditions including cataracts, macular degeneration and dry eye syndrome, to name but a few.
Now, with a far greater understanding of the many different factors associated with the development of glaucoma, researchers are looking more and more towards natural antioxidants and compounds and their related reactions on cell defense and signaling to support the integrity of the delicate tissues within the eye and to support the healthy flow of eye fluids and the aqueous humour.
