Lifestyle & Glaucoma - Wills Glaucoma
P: Nine months ago I started a walking routine, usually 45 to 50 minutes a day. After five months of that exercise, my blood pressure had dropped low enough that I no longer needed medicine to control it. My cholesterol also dropped. Further, I lost 17 pounds. The best news, however, is that at my last checkup my IOPs were10 mm Hg. My glaucoma specialist said that my visual field is stable. Since I have not changed glaucoma medication, I attribute the decrease in IOPs to walking. My IOPs have never been that low.
Dr. Rick Wilson: You are a good example: I see that all the time. In fact, when my son was born 21 years ago, I was found to have seriously high blood pressure. I started swimming four times a week and lost 15 pounds. I have never had to take medicine for high blood pressure as it dropped significantly.
You don't use it, you lose it!

The two studies address 2 seperate concerns. Both studies focus on lowering IOP as the vehicle for slowing down the disease progression.
1. OHTS - people with ocular hypertension: what are the chances that they develop POAG and will medication slow-down or prevent the disease.
2. EMGT - people with early manifest glaucoma: will medication prevent or slow-down the progression of the disease.
.
The Ocular Hypertension Treatment Study (OHTS)
Two Groups were studied for period of 5 years: one without medication(Observation Group) and a medication group. Note that the sample population selected had not developed POAG but exhibited high IOP. This is a very large study carried at multi-centers throughout America.
Selection of population study on basis of ages between 40 and 80 with IOP greater than or equal to 24 mm Hg but less than or equal to 32 mm Hg in at least one eye and IOP greater than or equal to 21 but less than or equal to 32 mm Hg in the fellow eye,
Study closed in June 1996.
Result of Study:
At end of 5 years, the study concluded the cumulative probability of developing POAG was 4.4 percent in the medication group and 9.5 percent in the observation group. There was little evidence of increased systemic or ocular risk associated with ocular hypotensive medication.
The study was able to highlight to doctors reasonable estimates of risk for individual ocular hypertensive patients and to determine which ocular hypertensive individuals are most likely to benefit from early prophylactic (preventive) medical treatment.
Baseline factors that predicted POAG included older age, larger vertical or hotrizontal cup-disc ratio, higher intraocular pressure, greater pattern standard deviation, and thinner central corneal measurement.

.
Early Manifest Glaucoma Trial (EMGT)
The study concluded in 2002 -- called the Early Manifest Glaucoma Trial conducted in Sweden-- followed 255 patients, aged 50-80 years, with early stage glaucoma in at least one eye. Most patients were identified in a population screening. The average age of the patients at the beginning of the study was 68 years. One group was treated immediately with medicines and laser to lower eye pressure, and the other group -- the control group -- was left untreated. Both groups were followed carefully and monitored every three months for early signs of advancing disease, using indicators that are extremely sensitive for detecting glaucoma progression. Any patient in the control group whose glaucoma progressed was immediately offered treatment.
After six years of follow-up, scientists found that progression was less frequent in the treated group (45 percent) than in the control group (62 percent), and occurred significantly later in treated patients. Treatment effects were also evident in patients with different characteristics, such as age, initial eye pressure levels, and degree of glaucoma damage. In the treated group, eye pressure was lowered by an average of 25 percent.
The findings from this study reinforce the known evidence that lowering eye pressure in glaucoma's early stages slows progression of the disease. It suggests that early detection and treatment will slow the disease progression.

What has our Health Ministry got to say about the 2 clinical trials:
IOP goals in specific groups of glaucoma patients
Recent large prospective randomised clinical trials conducted in the
US have provided some benchmarks that should guide the clinician
when managing specific categories of glaucoma patients.
It is recommended that glaucoma therapy in the local context should
be informed by, but not unduly constrained by, or indiscriminately
adherent to, the following trials:
- 1. The Collaborative Normal Tension Glaucoma Study (CNTGS)
2. The Advanced Glaucoma Intervention Study (AGIS)
3. The Collaborative Initial Glaucoma Treatment Study (CIGTS)
4. The Early Manifest Glaucoma Trial (EMGT)

Eye Supplements, Yes or No?
EYE SUPPLEMENTS, YES OR NO?
A PATIENT’S PERSPECTIVE
Sharon Siddique, PhD
All For Eyes Pte Ltd
Singapore
Whether or not to take vitamin and herbal supplements for eye health confronts everyone with low vision. We need to take this issue seriously because there is evidence that certain vitamin and herbal supplements appear to slow down (but not reverse) eye deterioration caused by eye conditions, such as AMD (age-related macular deterioration), glaucoma, and cataracts. It is up to the individual, in consultation with his/her eye doctor, to decide what is appropriate.
Information (as always) is the key. There are basically three approaches. Some believe that it is sufficient to eat a healthy diet, full of the types of foods that provide nutrients for eyes. Others feel that it is sometimes beneficial to supplement (or “top up”) this healthy diet with a selection of vitamins, minerals, and herbs. In Singapore we can also consider various types of TMs (traditional medicines), which include TCM (traditional Chinese medicine) and Ayurveda (traditional Indian medicine).
HEALTHY DIET
A healthy diet for eyes will include several portions of green, yellow, orange and red fruits and vegetables every day. Fortunately for us, Singapore markets have an abundance of greens (kai lan, yu choy, bak choy, Chinese cabbage, bitter gourd. etc), and yellow vegetables - carrots, peppers, squash, pumpkin, tomatoes and yams. Fruits such as papaya, kiwi, various melons, mango, oranges, pomelo, clementines, starfruit, grapes, persimmons, plums, etc. are plentiful. In Singapore, they are not only easily available, they are also relatively cheap.
So if we eat a healthy diet, is there a reason to take supplements? Some say no. But how many of us actually follow the “healthy diet” described above, on a daily basis? If we have to admit that we fall short of this ideal, it may make sense to consider adding certain supplements to our daily health regime. There is a bewildering number of vitamins, and it is easy to get lost in the terminology. Navigating through the information is challenging. Basically, there are Vitamins, Herbs, and Traditional Medicines (TM) to discuss.
VITAMINS
Antioxidants can help our eyesight because they prevent the damaging effects of oxidation, particularly in the retina. Vitamins A, C, and E are the most effective antioxidants. In addition to the vitamins themselves, there are a number of associated natural extracts (called carotenoids and flavonoids) that are found to be rich in these vitamins, and which may be easier for the body to absorb. Finally, Vitamins A, C, and E are more effective when taken together with certain minerals (zinc and, selenium) and other vitamins (particularly the B complex of vitamins).
Vitamin A and Carotenoids
Carotenoids are a class of highly unsaturated yellow to red pigments occurring in plants and animals. They are the natural extracts from which Vitamin A is derived. Three carotonoids most often mentioned in the context of eyes are beta carotene, lutein, and zeaxanthin. Lutein and zeaxanthin appear to be particularly important to eye health. They have been found to be highly concentrated in the macula of healthy retinas and appear to neutralize free radicals generated when ultraviolet and blue light strikes the retina.
Vitamin C and Flavonoids
Vitamin C is a major antioxidant in the lens of the eye. Flavonoids help the body to absorb Vitamin C, and assist in maintaining the intercellular glue (collagen) that strengthens connective tissue throughout the body. They have antioxidant powers and are essential for strong blood vessels, including the sensitive blood vessels of the retina. The most common flavonoid associated with eyes is rutin. Rutin has also been associated with maintaining healthy pressure levels within the eye. Other flavonoids, such as quercetin and the anthocyanidins, may help protect the lens of the eye from cataracts.
VITAMIN E AND MINERALS
Vitamin E functions mainly as an antioxidant. Vitamin E, also known as tocopherol, is a fat-soluble vitamin, so Vitamin E is carried through the body attached to fat. The body stores vitamin E in fat deposits and in the liver. The minerals zinc and selenium help the body absorb Vitamin E. Zinc is required for the function of certain enzymes in the retina that are critical for vision.
The B-Compound vitamins are needed for maintenance of the nervous system, and proper functioning of the cell and its energy metabolism. It is generally recommended that the B vitamins be taken in tandem, as their specific functions are interrelated. Riboflavin (vitamin B2) is manufactured in the body, and is needed to activate vitamin B6 (pyridoxine), which may ease watery eye fatigue and may be helpful in the prevention and treatment of cataracts. The B vitamins include thiamine (B1), Riboflavin (B2), Niacin (B3), Pantothenic acid (B5), Pyridoxine (B6), Biotin (B7), Folic acid (B9), and Cyanocobalamin (B12).
HERBS
Bilberry, a close cousin to the blueberry, has long been widely used in Europe for eye health. Bilberry is rich in fatty acids, flavonoids, iron, zinc, and selenium. During World War II British Royal Air Force pilots reported improved night visual acuity on bombing raids after consuming bilberry jam. Subsequent claims have been made that bilberry extracts result in improved night visual acuity, quicker adjustment to darkness and faster restoration of visual acuity after exposure to glare. Bilberry has been used in the treatment of glaucoma as well.
The herb Eyebright is great for the eyes. Since the Middle Ages, Eyebright has been a popular herbal eyewash. Eyebright's antibiotic and astringent properties tighten membranes and mucus surrounding the eyes, effectively strengthening and improving circulation. Eyebright contains bitters, essential oils, flavonoids, several B vitamins, and Vitamins A, C, D, and E. Today Eyebright is used for relieving eye problems such as eye strain, pink eye and inflamed, irritated and sore eyes Eyebright is also used for cleansing and purifying the blood, therefore stimulating healthy liver functions.
TRADITIONAL MEDICINE (TM)
We are familiar with Bilberry and Eyebright because they are European, and they are therefore much better marketed. With regard to Asian traditional medications, we are barely scratching the surface of fascinating connections and similarities between European, Chinese and Indian TM in general, and, in our case, as applied to eye health. Here are two examples.
In both Chinese and Indian TM, there is a direct relationship between herbs used for the treatment of liver function, and the eyes. Wolfberries, for example, are the Asian cousin of the European bilberry, and are cheap and plentiful in dried form, found in any Chinese medical hall in Singapore. Called "goji" in Chinese, ancient Chinese medical texts extolled wolfberries for strengthening the eyes, liver, and kidneys as well as fortifying the "qi" (chi) or life force. There are also interesting parallels in Indian traditional medicine. Triphala is a composite herbal preparation containing equal proportions of three native Indian fruits, and it is taken for various eye disorders, as well as cleansing the liver.
The turmeric root is also used to support liver function, as well as eye health, in both Ayurvedic (Haridra) and Chinese (jiang huang) herbal medicine. Turmeric protects against the damaging effects of toxins and free radicals. Turmeric, which is a member of the ginger root family, is a deep yellow colour, and is commonly used in Indian cooking. And hence we return to the diet, which, according to Western health directives, should contain plentiful supplies of eye friendly green and yellow vegetables. It is difficult to find anything more intensely yellow than turmeric!
SUMMING UP
We are fortunate to be in Singapore, where off-the-shelf vitamins and supplements have been tested and approved by the Ministry of Health. There are many Western multi-vitamin supplements which are specially formulated for eyes, as well as herbal preparations and traditional medicines. They are available throughout Singapore, and generally contain various combinations of the vitamins and herbs mentioned above. So investigate this interesting subject, and discuss it with your GP and ophthalmologist. It is up to each of us to take responsibility for doing everything possible to preserve our precious gift of sight.

Should Glaucoma qualify for the Medisave Chronic Disease Management Programme?
Should we qualify? : YES
Are we presently in the Scheme? : NO
Here are my reasons why Glaucoma should be included:-
- Glaucoma is a chronic disease and has to be managed for life
It is a progressive disease and thus cost of management increases with time
Medication is expensive and cost of early-stage glaucoma management exceeds $500 per year and may increase to over $1000 with some cases in a couple of years. This is apart from consultation charges, vison testings, etc
Cost of surgery for advanced-stage glaucoma management is prohibitive and may need to be repeated with time to prevent blindness
The disease affects more the aged-population; the elderly who are without a source of income
Glaucoma carries a stigma on employability; other chronic diseases such as diabetes do not!
- There are presently no subsidy for LOW VISION AIDS
I like to have readers opinion too.

Xalatan - eyedrops from Pfizer
Pfizer on Xalatan
Look what I found, but ask your doctor first, and secondly our room temperatures are much higher ...
How should I store XALATAN?
•Are you wondering why you have to refrigerate your prescription XALATAN before opening but not the free sample from your eye doctor? There’s a good reason! The expiration date (shelf life before opening) determines whether refrigeration is required. And the expiration for prescription XALATAN from the pharmacy and sample XALATAN from your doctor are different.
•Prescription XALATAN has an 18-month expiration date until you open it. This longer shelf life makes refrigeration necessary until you open it
•Samples of XALATAN have a 12-month expiration date. This shorter shelf life allows doctors to easily store samples at room temperature in their offices
•Once opened, your sample or prescription XALATAN may be stored at room temperature (up to 77°F) for 6 weeks

The Importance of Sunglasses: A Patient's Perspective
THE IMPORTANCE OF SUNGLASSES:
A PATIENT’S PERSPECTIVE

THE SUN’S HARMFUL RAYS
In tropical Singapore we are all aware of the damage that the sun can do to our skin. Protective clothing and sun creams are commonly used to try to prevent sunburn, wrinkles, and skin cancer. Unfortunately, we are much less aware of the damage that strong sunlight can do to our eyes. Too much exposure to ultraviolet (UV) radiation can leave the eyes red, teary, strained, and light sensitive. Just as with the skin, damage is cumulative, and can lead to an increased risk of cataracts and retinal damage, including AMD (age-related macular degeneration).
UV radiation is so potentially dangerous because we literally can’t “see” it. It is composed of invisible, high-energy, light rays from the sun that are found beyond the violet/blue end of the visible spectrum. Our eyes are particularly sensitive to damage from ultraviolet A (AV-A) and ultraviolet B (UV-B) light. Children, the elderly, and those of us with eye problems are particularly at risk.
Children’s eyes are more vulnerable because their pupils are larger, meaning more light enters the eye, and reaches the retina. By the age of 18, studies show that more UV light will have been absorbed by a child's eyes than over the rest of his life. And yet we seldom see Singaporean children using sunglasses. As Singapore’s population ages, we are already seeing the effects of long-term exposure to the sun’s harmful rays as the rates of cataract and AMD increase.
Ultraviolet protection is especially important for people after cataract surgery. Since the lens absorbs UV radiation, individuals who have had cataract surgery are at increased risk of retinal injury from sunlight. This is because although the lens implant contains some UV blocking agents, it does not provide the same degree of protection to the macula as the natural lens. Taking certain medications - such as tetracycline, sulfa drugs, birth control pills, diuretics and tranquilizers – also increases the eye's sensitivity to light, and potential damage.
A good pair of sunglasses should protect against harmful UV light entering the eye. Ask before you purchase. Do the lenses provide both UV-A an UV-B protection? Are the lenses polarized, which ensures that they will reduce reflected glare? Do the frames fit snugly to provide the eyes with maximum protection, particularly over and around the rims of the frames? Sunglasses which are specifically designed to fit-over a normal pair of spectacles may be particularly suitable for many spectacle-dependent Singaporeans.
THE CONFUSING WORLD OF COLOURS
There is a big misconception that the darker the lens, the better the protection. In fact, UV coating is colourless. Clear lenses, with no colour-tint, can still be UV-light blockers, and they are very useful in protecting the eyes from impact, debris, dust, chemicals, or after eye surgery. Clear lenses can be used during low light or nighttime activities, and are particularly effective to reduce glare under fluorescent light.
Most sunglasses come in a bewildering range of colours, from common amber and grey, to yellow, red, green, and even orange and plum. Does this mean, then, that the choice of colour is merely cosmetic? Absolutely not. Different colours absorb or transmit specific wavelengths of light. That is why, for example, when we look through red-coloured lenses, the world looks, well, rosy.
So when and why is the choice of colour important? Those of us with eye problems need to pay particular attention to these “colour codes” because by absorbing and transmitting certain specific wavelengths of light, tinted lenses – also called absorptive lenses - can improve our ability to see. For example, glaucoma-sufferers typically perceive the world as being "too dark." As a result, they may show a preference for yellow lenses, which increase the apparent brightness of objects or surroundings. People with macular degeneration may favour an orange, yellow-orange or plum tint. And people with retinitis pigmentosa may prefer an orange or red tint to reduce glare.
The two most commonly available colours for sunglasses are grey and amber. Grey lenses are described as neutral because they do not enhance contrast or distort colors. Choosing lighter shades of grey can help relieve indoor glare, especially under fluorescent light. In general, grey is soothing, sharpens focus, and provides good glare protection. Grey is often the colour of choice for post-op cataract surgery, glaucoma sufferers, diabetics or people who have had corneal transplants.
Amber tints are known for their “blue blocking", protective effect. There is some evidence that the retina may be more sensitive to blue visible light. Blocking the visible blues eliminates much of the scatter created by the shorter wavelengths of light. The result is an apparent increase in contrast and depth perception. Objects appear more clearly defined, and thus amber tints are popular with skiers, boaters, and pilots. They also provide good contrast enhancement, useful for those with macular degeneration, and retinitis pigmentosa.
Yellow is a powerful a "blue-blocker" because the color keeps blue light from entering the lens. Yellow and orange sunglasses make objects appear sharper, with more contrast, but there is some colour distortion. Both yellow and orange are helpful for reading. Yellow is often the choice of those suffering from retinitis pigmentosa and macular degeneration because it provides maximum brightness and good visual acuity. Yellow glasses are great for relieving eye fatigue from prolonged exposure to computer screens. Orange is even more effective than yellow for intensifying backgrounds, allowing the wearer to see objects more clearly.
For normally sighted people, red is a rather uncomfortable color to look through, but it is recommended for certain eye conditions. Red does cut down on blurred vision caused by blues, greens and yellows. Red lenses are good for medium and lower light conditions because they enahnce contrast. Reds and pinks are great in alleviating computer eyestrain, but there is also a certain amount of color distortion. A light or medium tinted lens is good for day-to-day wear. Dark plum is an excellent dark lens, and provides a high amount of glare relief.
Green is a less commonly found colour, but it offers some color contrast with little or no color distortion. Green is also great for glare protection. Because green allows only low levels of visible light to enter the eye, it is a good colour choice for post-op cataract surgery and glaucoma.
SUMMING UP
A final thing to pay attention to in the confusing world of colours is what is called the VLT (visible light transmission). Some types of sunshades come with a colour and a VLT, expressed in percentage terms. Thus, “40% Amber” means that the tint is amber, and that 40% of the visible light is transmitted through the lens. Sometimes the terms “light” (generally over 70% VLT), “medium” (10% to 69% VLT) and “dark” (below 10% VLT) are indicated.
To maximize visual acuity, select the highest visible light transmission (VLT) which is comfortable, and a colour that “feels” good. There is no one correct fit. It depends very much on the conditions under which the sunglasses are going to be used, and the condition of the eyes. Many people require different filter transmissions for cloudy and bright conditions or for inside versus outside applications. In general, the goal is to achieve the maximum visual acuity, while minimizing eye discomfort and strain.
In sum, sunglasses are an ESSENTIAL part of the proactive patient’s vision tool kit. Choose a pair of sunglasses carefully. Decide under what conditions you are going to be wearing them (inside/outside; bright sunny/hazy conditions). Make sure they fit around your eyes to block out glare, that you have maximized your visual acuity with the tint and VLT, and that they are polarized, scratch-proof, and provide 100% UV-A and UV-B protection. Above all, they should fit comfortably – otherwise you won’t wear them. And remember, often our eyes do warn us that they are under stress by tearing, blurring, redness, dryness, and pain. Learn to listen to them.
