A poor diet consisting of highly processed foods with large amounts of salt and sugar can increase the risks of developing diabetes and many other health problems that can lead to blindness.

Jacqueline Gattegno, a Smart Vision Optometrist at Eyes InDesign Bondi, explains the importance of healthy food to maintain eye health. “Try adding some eye-friendly food to your diet, it can help improve vision and ward off diseases. While it’s important to nourish the body, adding certain nutrients can improve vision, especially in children. A well-balanced diet can help children develop vital learning skills and prevent vision loss,” Jacquie suggests.

We all know that a child’s development can vary immensely from child to child. It is perhaps not as well known that a child’s vision also develops over time and can also vary from child to child.

“Having a vision problem can affect a child’s academic performance and quality of life,” says Jacquie,” She explains the relationship between vision and learning; and why it is so important for parents to understand the difference between sight and vision. “Often it is not until children begin to read that we first notice they have a vision problem. This is the time when they start using their visual system more intensively to tune into small details. The level of demand on visual skills required for reading increases throughout a child’s learning years.”

 A healthy lunch box is a great start to help boost the nutrients children need to protect them from eye health issues such as the formation of cataracts, and macular degeneration. A good diet can also reduce the effects of dry eyes and other eye problems.

It is often a struggle to get children to eat more fruit and vegetables, but it is these that provide essential nutrients that children need for healthy vision. Including sliced fruit or vegetables in children’s lunch boxes can be a great way to tempt them with easy to eat bite-sized snacks. Some great options include apples, blueberries or strawberries. Citrus fruits deliver powerful antioxidant levels that can help prevent cataracts later in life, so the inclusion of oranges and mandarins can be beneficial. Citrus fruit can also help lower the risk of diabetes and blindness.

Studies have shown that vegetables, such as kale and spinach, can also support healthy eyesight as they contain the carotenoids zeaxanthin and lutein necessary for the development and maintenance of healthy retinas. “Beta carotene can be found in capsicum, carrots, and tomatoes and helps protect eyes from night blindness. These foods can also be used as tasty snack options and are simple enough to prepare each morning. Beta carotene is also beneficial for protecting children from diabetes-related ocular diseases,” Jacquie says.

Eggs, oily or fatty fish, and nuts are great sources of omega 3, which supports healthy eye function and brain development in early childhood. Essential fatty acids protect the retina from weakening and can reduce the effects of dry eyes and other eye problems. “Excellent options for quick and easy lunches are tuna and crackers or salmon fishcakes,” says Jacquie.

A deficiency in zinc can lead to deterioration in the macula, which is the centre of the retina responsible for central vision. Eating fresh meats and green vegetables can help protect the macula from disease, including macular degeneration. As well as being used in a variety of metabolic processes throughout the entire body, zinc also helps transport other nutrients to the eye. “An easy way to get extra zinc into children’s diets is through zinc-fortified cereals or pumpkin seeds, which have added vitamins and minerals,” says Jacquie.

Diabetic Disease Awareness Month aims to increase the awareness of diabetes, and diabetic eye disease.

Diabetes is the leading cause of blindness in adults, therefore it is important to seek treatment for vision impairment that are related to diabetes.

As the number of people living with diabetes grows, so does the number of people with impaired vision.

High blood sugar levels damages the blood vessels of the retina, and can cause permanent vision loss.  Vision impairment caused by Diabetic Retinopathy (DR) may be prevented by regulating blood sugar and blood pressure levels as well as regular eye examinations at your local Smart Vision Optometry.

Jacquie Gattengo, a Smart Vision Optometrist at Eyes InDesign Bondi, explains the four stages of DR and what preventable measures can be taken to reduce the disease from advancing, and causing permanent vision loss.

There are two types of DR; Non proliferative retinopathy – which refers to the bleeding of the retina or leakage of blood – and proliferative retinopathy whereby abnormal blood vessels grow on the retina. The blood may bleed in the centre of the eye, causing vision problems.

Micro aneurysms (MA) occurs in patients with non-proliferative diabetic retinopathy (NPDR) when the capillary walls leak fluid due to the haemorrhage of blood vessels.

Stage one: Mild NPDR

The first stage consists of mild non-proliferative retinopathy, which is an early stage of DR. In this stage, “small areas of swelling or bulges occurs in the blood vessels of the retina,” says Jacquie.

Vision may not be affected yet during this stage.

Mild NPDR has at least one MA. Such findings are elusive, therefore close monitoring and inspection are crucial.  Patients should have an extensive eye examination once a year.

It is also essential that “patients diagnosed with diabetes monitor their blood sugar level and diet,” says Jacquie.

Stage 2: Moderate NPDR

As the disease progresses, it results in moderate non-proliferative diabetic retinopathy, where some of “the blood vessels that nourish the retina becomes blocked and damage the retina,” says Jacquie.

Blood and other fluids build up in the small central part of the retina causing diabetic macular edema. Vision may be affected in this stage.

Patients with moderate NPDR should have an eye examination at least twice a year.

Stage 3: Severe NPDR

The third stage consists of an additional blockage of the blood vessels, “this disrupts the blood supply to the retina,” says Jacquie. The damaged retina signals the body to produce new blood vessels. The development of new blood vessels grows in the retina and fills the interior of the eye. “The obstructed blood vessels may lead to blurred vision with dark spots visible,” says Jacquie.

Multiple haemorrhages occur in the retinal quadrants. During this stage, retinal detachment may occur.

“Patients with severe NPDR should have a dilated fungus examination three or four times a year,” advises Jacquie. These patients are at high risk of disease progression and permanent vision loss

Stage 4: Proliferative Diabetic Retinopathy (PDR)

During this stage, “the new blood vessels are abnormal and rupture causing a flow of blood to the retina,” says Jacquie.

The growth of abnormal and fragile new blood vessels advance during this stage. “These blood vessels have fragile walls and can leak blood in the retina, causing severe vision loss and blindness,” says Jacquie.

Patients exhibit either neovascularisation of the eye or pre-retinal haemorrhage. Until the disease stabilises, it is required that they visit a retinal speciality once a month.

Eye examinations

There are usually no warning signs of Diabetic retinopathy (DR), however early signs of DR can be detected up regular eye examinations. The procedure of such examination includes near and distant eye tests, a dilated eye exam (which allows the examiner to see through the pupil to the retina), and a tonometry test to measure the fluid pressure in the eye.

Patients with type 1 or type 2 diabetes, are at risk of developing neurovascular complications that can lead to Diabetic Retinopathy (DR). It is advised that “patients with diagnosed type 1 and type 2 diabetes should have a comprehensive dilated eye examination,” says Jacquie.

Lifestyle is a major factor thought to influence susceptibility to many diseases including the eye. Lifestyle disease or disorder can be a result of the consequence of one’s health choices. Unhealthy lifestyle choices such as alcohol consumption, smoking, fat and sugar rich diet, lack of physical activity, poor sleep patterns and chronic eye strain are associated with the risk of developing eye diseases.

Gary Rodney, Master of Optometry and Fellow of the International Academy of Orthokeratology and Myopia Control (FIAOMC) based at the Smart Vision Optometry Eyes InDesign Mosman clinic, advices the significance about diabetic eye disease and Hypertensive Retinopathy.

Diabetic Retinopathy

Diabetic Retinopathy (DR) is an eye disease caused by the onset of diabetes. It is caused when high blood sugar levels damage the blood vessels of the retina.

“You may have diabetic retinopathy, and not even know it,” says Rodney. In the early stage of DR, no symptoms are shown. As this condition advances, one may “experience blurred vision, black or dark spots in the vision, and colours may appear faded,” says Rodney.

Another contributing factor to DR is smoking. Smoking is believed to increase tissue hypoxia (lack of oxygen in cells and body), a factor involved in developing diabetic retinopathy.

DR can be personally treated, such as bringing blood sugar and blood pressure levels under control. Stop smoking and maintain a healthy lifestyle to improve overall health and prevent unnecessary vision loss.

Maintaining a healthy balanced lifestyle and the richness of vitamins in meals are crucial to one’s health, and eye health. “Vitamin A plays an important role in keeping the retina and night vision in working condition,” says Rodney. “Vitamin E helps protect the eye from age-related macular degeneration (AMD),” says Rodney, and “vitamin C can help to fend off cataracts”.

Hypertensive Retinopathy

High and untreated blood pressure (hypertension) can affect one’s vision and lead to eye disease. Hypertension can cause damage to the blood vessels in the retina. This eye disease is known as Hypertensive Retinopathy.

Hypertensive Retinopathy (HR) is strongly associated with diabetes, and is related to blood pressure status. “High blood pressure causes blockage of the retinal arteries (blood vessels) that supply blood and oxygen to the eye,” says Rodney.

Retinal haemorrhages are commonly seen when there is a breakdown of blood-retinal barriers. “HR occurs when the force of blood against the artery walls is too high, causing damage to the artery.” says Rodney.

High blood pressure is a risk factor for many ocular conditions, such as glaucoma and age-related maculopathy (AMD). This condition can lead to double or dim vision, loss of vision and headaches.

Mild hypertensive retinopathy comes about due to “elevated blood pressure, and risks other chronic effects such as cardiovascular disease (CVD)”, says Rodney. When diabetes is associated with hypertension, cardiovascular risk rises, and retinopathy becomes more severe and rapidly progresses.

Moderate grade of hypertensive retinopathy, reflects higher in people with diabetes. Diabetes and hypertension are both vascular risk factors, and the prevalence of diabetes among patients with hypertension is high.

Symptoms of mild to moderate hypertensive retinopathy are not always experienced, but can be discovered upon regular eye examinations.

Treatment for Hypertensive Retinopathy includes “controlling high blood pressure through lifestyle changes,” says Rodney. The control of blood pressure in hypertensive diabetic people prevents cardiovascular risks as well as the deterioration of retinopathy and visual acuity.

Chronic conditions can cause eye symptoms, such as dry eye, damaged blood vessels and blindness. Many eye problems are preventable and treatable.

Jacqueline Gattengo, a Smart Vision Optometrist at Eyes InDesign Bondi, explains common illnesses that cause many eye problems.

Diabetes

People with diabetes often have problems with the blood vessels in their body, and the eye is no exception. Diabetes causes many complications, including Diabetic Retinopathy (DR).

DR is caused by the onset of diabetes. “High blood sugar and high blood pressure levels can damage the blood vessels in the back of the eye, that supply blood to the retina,” says Jacquie. A lack of blood supply can affect vision and cause permanent blindness. DR can be prevented by regulating blood sugar and blood pressure levels.

High blood sugar levels increase the risk of dry eyes. “Dry eye causes significant eye discomfort and impaired vision,” says Jacquie. The symptoms include redness, a scratchy sensation of the eye, and blurry vision. The cause of dry eye is typically a lack of tears to keep the eye moist and healthy.

People with diabetes are also at higher risk of developing cataracts and glaucoma.

Nutritional deficiency

Vitamin A deficiency can cause severe dry eye and lead to ulcers of the cornea. A lack of vitamins can increase the risk of developing cataracts.  

“Cataracts are caused by the build-up of protein which clouds the lens of the eye, causing blurry vision and blindness,” says Jacquie. If left untreated, this condition will worsen and lead to blindness.

Jacquie says, “cataracts can also be caused by diabetes, smoking, high blood pressure and a history of cataracts in blood relatives.” 

“Many people are not aware of the effects of smoking on their vision,” says Jacquie. Smoking is associated with many health problems, including eye health. Smoking contributes to cataracts by “altering the cell of the lens through oxidation,” says Jacquie, and the “heavy metal like cadmium accumulates in the lens.”

Regular eye examinations are important to “test, diagnose and treat eye deficiency before they become progressively worse,” says Jacquie. Cataracts are more prominent in people who are diabetic. Therefore, it is important to “maintain high and low blood sugar levels,” says Jacquie.

Corneal Ulcer

A cornea ulcer is a common eye condition that is often caused by bacterial infections. This causes an ulcer to form in the front part of the eye.  People with “vitamin A deficiency and those who wear contact lenses are at a higher risk of cornea ulcers,” says Jacquie, as infectious agents are trapped behind the lens.

Jacquie identifies symptoms of cornea ulcer that include, “pain, intense redness, a scratchy sensation of the eye, light sensitivity and blurred vision.”

If you suspect you have a cornea ulcer, visit your local Smart Vision Optometry for an eye examination.

High blood pressure

High blood pressure can cause a change in the retina as it damages the blood vessels that supply the eye.

Controlling high blood pressure levels is fundamental for the vision of the eyes. “The longer the blood pressure levels remain high, the more an individual is at risk of having permanent eye damage,” says Jacquie.

High blood pressure may be diagnosed during a regular eye examination.

Autoimmune disease

Autoimmune disease is a condition whereby the immune system mistakenly attacks healthy cells of the body. The autoimmune attack causes inflammation of the optic nerve that damages the eye and affects vision.

People with autoimmune disease experience common symptoms such as “dry, red and itchy eyes, light sensitivity, eye pain, and change in vision,” says Jacquie. Treating the autoimmune disease will help control eye problems caused by the condition.

Rheumatoid arthritis

Rheumatoid arthritis, a collagen vascular disease, increases the risk of dry eye, as infections with bacteria or viruses affect the eye.

This condition can be treated with eye drops

Infectious diseases

Infections can affect the condition of the eye as well as one’s eyesight. Pink eye or conjunctivitis is a common form of eye infection. Common symptoms include redness and swelling of the eyelids and eye pain.

Trachoma

Trachoma begins with a bacterial infection, similarly to conjunctivitis (pink-eye), and can be easily treated.

However, if the condition is left untreated, “the condition will worsen as it causes scarring to the eyelid that pulls the eyelashes inwards,” says Jacquie. This causes tremendous pain as every blink scrapes the eye.

Advanced trachoma is called trichiasis, which occurs when the eye is inflamed. “Scar tissue builds up inside the eyelid, making the eyelid tight, pulling the eyelashes inward,” explains Jacquie.

Symptoms of trachoma include discharge from the eye, irritated eyes and redness. This causes immense pain as the eyelashes scrape against the cornea. This can lead to blindness.

Trachoma can be treated with cleanliness and hygiene, regularly wash your bedding, clothes and face to prevent infection.

It is important to be aware of other diseases that affect the eye, as if left untreated and undiagnosed, it can result in permanent blindness and vision impairment.

He says: “Those who want their car to run well, will ensure the right fuel and oil is used so all its systems work smoothly. It makes sense that eyes, the organs which provide 80% of the information which shapes and guides people’s lives and how they see the world, should be given the same treatment.”

Lessening the Worst of the Worst

According to Rodney, research has shown that the wrong food can impact on vision in general, and also play a role in the development or worsening of chronic eye diseases.  On the contrary, an eye-friendly diet keeps the eyes healthier, lessens the likelihood of eye problems, slows the progression of chronic eye conditions, and lowers the risk of vision loss.

He says an eye health diet is vital when it comes to the top four vision destroyers. These include the eye-clouding cataract; age-related macular degeneration that blurs central vision; diabetic retinopathy which impacts on the retina’s blood vessels; and glaucoma, the world’s largest cause of blindness in those over 60. This eye disease which affects around 76 million people globally, raises the pressure levels in the eyes and damages the optic nerve responsible for conducting visual data from the eyes to the brain.

Eating the Way to Healthier Vision

Rodney says an eye-healthy diet should not include highly processed foods, frequent take-outs and fast-foods like burgers, milkshakes, pre-packed dinners, as well as carbohydrates, fried foods and margarine, which can clog the thin arteries supplying blood to the eyes.

Diabetics, or those who are insulin resistant, should keep clear of sugar to lower the chances of diabetic retinopathy, or slow its progression if already present. Carbonated drinks, and specially those sweetened with corn syrup, are also not recommended, as they can increase blood pressure, which can lead to vision problems. 

Using What’s Good in the Food

On the other hand, a diet which is low in fat, sugar and chemicals, but rich in fruits and vegetables can help protect the eyes’ health, says Rodney, and certain vitamins and minerals have long been seen to support eye health.

Among these stalwarts is Vitamin A, which keeps the eye’s light-sensing cells, used in the harvesting of visual information, in shape. It’s found in orange vegetables and fruits such as carrots, sweet potatoes, apricots and cantaloupes.

Studies also suggest the Vitamin C in oranges, lemons, grapefruit, strawberries,  blackberries, raspberries, bell peppers and tomatoes; and the Vitamin E from avocados, almonds and sunflower seeds and nuts may, at the very least, slow age-related macular degeneration and cataract, and protect the eyes from  environmental problems, smoking, and over-consumption of processed food and take-outs.

So will the two anti-oxidants, lutein and zeaxanthin, found in leafy green vegetables such as kale, spinach, romaine lettuce, turnip greens, peas and broccoli and in eggs;  and the zinc in chickpeas, beans, oysters, lean beef and yogurt.

Omega-3s have been associated with a reduction in the risk of diabetic retinopathy in older adults, and it’s also being investigated with regard to helping with dry eyes. Omega-3s are found in oily fish such as salmon, sardines and tuna, as well as in nuts.

NOTE: Rodney says any eye-health diets should be discussed with eye doctors, whether they’re for coping with severe and sight-threatening diseases, or for improving general eye health and sight. This is important as some supplements or vitamins will only show positive effects if there is a deficiency in them.

THE ONE THING YOU DIDN’T KNOW ABOUT CHOCOLATE

Whilst Easter is traditionally a religious celebration, it has evolved today into time dedicated to family and friends while indulging in a little bit of chocolate! So while we all contemplate the up and coming celebrations, whilst worrying ever so slightly about the expanding waistlines, we thought we would share some good news with you…Chocolate might just be good for your eyes!

Research has shown that dark chocolate can improve people’s vision. This is thought to be because of the higher concentrations of flavonoids found in dark chocolate, which may increase blood flow to the brain and retina of the eye. Vitamin A, which is essential for normal eye function and can reduce the onset of eye diseases such as macular degeneration, can also be found in dark chocolate.

One study in particular^[1] tested the vision of 30 healthy adults before and after eating chocolate. Those who ate dark chocolate out-performed their previous tests and the other test subjects. Moreover, the scientists claimed that cocoa improves cognitive ability.

When eaten in moderation, dark chocolate can be a source of copper, magnesium, iron, manganese, potassium, phosphorous, selenium, zinc and fibre. The copper in dark chocolate aids in preventing damage to the optic nerves^[2]. 

Well if that’s not great news, we don’t know what is!

Unfortunately, white and milk chocolate just won’t do. They are often higher in sugar and fat and do not contain enough cocoa to offer the same level of health benefits. When choosing dark chocolate, go for options that are higher in cocoa (ideally 70 – 80%), as many of the health benefits come directly from the cocoa.
