You might be surprised at how many tests eye doctors use to diagnose glaucoma. A proper diagnosis requires careful evaluation of many aspects of your eye’s health – from eye pressure to cornea thickness to the health of your optic nerve. This article describes how your eye doctor assesses your risk and all the tests needed to properly diagnose glaucoma.

Risk Factor Assessment

Your eye doctor will begin by assessing your risk level for developing glaucoma. This will help determine the frequency and extent of testing needed. Through a family history and medical questionnaire, the eye doctor is looking for the following risk factors:

• Over the age of 60

• Ethnic background such as African or black Caribbean descent, Hispanic, or Asian

• Family history of glaucoma, such as a sibling or parent with glaucoma

• History of eye conditions, injuries or surgeries

• Prolonged corticosteroid use (eye drops, pills, inhalers or creams)

• Chronic conditions that affect blood flow, such as migraines, diabetes, low blood
  pressure or hypertension

• Current or former smoker
   

If you’ve already had a comprehensive eye exam, your eye doctor will also consider these risk factors:

• Eye pressure higher than normal (above 21 mm Hg)

• Thin corneas (less than 0.5 millimeters)
   

Your type of eyesight is also important. People with farsightedness are at a higher risk for narrow-angle glaucoma, a more serious type that can advance quickly. While nearsightedness is associated with open-angle glaucoma, which progresses slowly without any symptoms.

If you have dry eye syndrome, you understand the frustration of repeatedly applying eye drops and other therapies in vain. The iLux®, a new product on the market, may help address your problem. 

It treats dry eye syndrome by combining heat and pressure to clear obstructions from the meibomian glands. Learning how it works and its advantages in treating dry eyes may help you.

What Is iLux?

Millions of individuals worldwide suffer from the prevalent ailment known as dry eye syndrome. This happens when your eyes do not produce tears in sufficient amounts or when tears evaporate too soon. Discomfort, irritability, and even eyesight issues may result from this. Although several treatments for dry eyes exist, many are transient and call for repeated application.

iLux is a medical device designed to treat dry eye syndrome. It combines heat and pressure to remove blockages from the meibomian glands. These glands in the eyelids produce the oil that prevents your tears from evaporating too quickly. 

The handheld device is easy to use, making it a convenient and effective solution for those who suffer from dry eyes. It is a practical choice for people with busy schedules because no downtime or recovery period is necessary.

How Does It Work?

The device works by applying gentle heat and pressure to the eyelids. This helps loosen and remove blockages from the meibomian glands. The treatment allows the glands to function properly, producing the necessary oils to keep the eyes moisturized and healthy. The device also provides targeted treatment to specific areas of the eyelids. This allows for a more customized and effective treatment experience.

Benefits 

Using this medical device to treat dry eyes offers numerous benefits, including:

• Improved Comfort

Dry eyes can cause discomfort, irritation, and even pain. By treating dry eyes with iLux, you can experience improved comfort and reduced symptoms.

• Enhanced Vision

Dry eye syndrome can affect vision, causing blurriness or difficulty focusing. Treating the condition with iLux can help improve vision and clarity.

• Noninvasive

Unlike other treatments for dry eyes, such as surgery, iLux is a noninvasive solution that requires no downtime or recovery period.

Seasonal allergies is a medical condition similar to other forms of allergies that occur when the body's immune system reacts to an external material in the environment during seasonal periods when plants and trees are pollinating. Seasonal allergies have a tremendous effect on millions of individuals annually causing a negative effect on eyesight. Seasonal eye allergies cause the eyes to become itchy, watery and red which in medical terms is referred to as allergic conjunctivitis. There are many allergens that can make our eyes go itchy and very red including dust, pollen, and smoke. These allergens, however, vary from one person to another. For example, while dust can cause itchy eyes for me, it might not be the same for you as it all depends on our immune system and the way it reacts against such substances.

When something is regarded as a dangerous substance by the eye, a chemical response is elicited to fight against the allergen which is what leads to the itchiness, redness, and soreness in the eyes. These reactions are usually a result of a change in seasons, mostly occurring in the spring when plants and trees are pollinating and during the fall when the ragweed plants are pollinating.

Seasonal Allergies Effect on the Eyes

As we mentioned earlier, allergens affect people differently, but there are general ways in which everyone reacts. You would know an individual is suffering from allergies through the following symptoms.

• Teary eyes - Since the eyes perceive substances like dust, smoke, pollens as harmful to the normal conditioning of the eyes, there is an automatic release of water in order to clean the eyes which is more of a defense mechanism against these foreign items.

• Swollen eyes - After the entry of these foreign items, it is very natural to feel itchy and want to scratch the affected eyes. During the scratching, the skin covering the eyes would become swollen due to continuous friction.

• Dry eyes - Dry eyes occur most times during winter seasons, not because of allergens like dust or pollen, but whenever there is extreme cold or snow. This causes the eyes to become dry which leads to soreness and redness.

• Itchy Eyes - Allergens are carried by air and could end up in your eyes at any time. A reaction to these allergens would cause your eyes to feel irritated from the inside and would create the urge to then scratch your eyes in an attempt to provide some relief.

• Red Eyes - Redness of the eyes is usually accompanied by other symptoms such as itchy eyes which cause the eyes to become swollen and very red. There are also capillaries inside the eyes that can become red whenever one is faced with an allergy.

Dry Eye can have a major impact on your quality of life. You may find your eyes get tired faster or you have difficulty reading. Not to mention the discomfort of a burning sensation or blurry vision. Let’s take a look at dry eye treatments – from simple self-care to innovative prescriptions and therapies – to help you see clearly and comfortably.

What is Dry Eye?

Understanding dry eye will help you determine the best treatment option. Dry eye occurs when a person doesn't have enough quality tears to lubricate and nourish the eye. Tears reduce eye infections, wash away foreign matter, and keep the eye’s surface smooth and clear. People with dry eyes either do not produce enough tears or their tears are poor quality. It’s a common and often chronic problem, especially in older adults.

Preventive Self-Care

Before we delve into more serious dry eye treatment options, here are a few simple self-care options that can manage minor cases of dry eye.

• Blink regularly when reading or staring at a computer screen for a long time.

• Make sure there’s adequate humidity in the air at work and at home.

• Wear sunglasses outside to reduce sun and wind exposure. Wraparound glasses are best.

• Take supplements with essential fatty acids as these may decrease dry eye symptoms.

• Drink 8 to 10 glasses of water each day to avoid dehydration.

• Find out if any of your prescriptions have dry eye as a side effect and if so, see if you can take an alternative.

Artificial Tears

For mild cases of dry eyes, the best option is over-the-counter eye drops. Here are a few tips for selecting the right one:

• Low viscosity – These artificial tears are watery. They often provide quick relief with little or no blurring of your vision, but their effect can be brief, and sometimes you must use these drops frequently to get adequate relief.

• High viscosity – These are more gel-like and provide longer-lasting lubrication. However, these drops can cause significant blurring of your vision for several minutes. For this reason, high-viscosity artificial tears are recommended at bedtime.

Prescription Dry Eye Treatments

There are several prescriptions that treat dry eye differently. Your eye doctor can advise the best option for your situation.

• Contact Lenses – There are specialty contact lenses that deliver moisture to the surface of the eye. They’re called scleral lenses or bandage lenses.

• Antibiotics– If your eyelids are inflamed, this can prevent oil glands from secreting oil into your tears. Your doctor may recommend antibiotics to reduce inflammation.
   

• Anti-inflammatory drugs – These are eye drops to control inflammation on the surface of your eyes (cornea) using the immune-suppressing medication cyclosporine (Restasis) or corticosteroids.

• Eye Inserts – If artificial tears don't help, another option may be a tiny eye insert. Once a day, you place the hydroxypropyl cellulose (Lacrisert) insert between your lower eyelid and your eyeball. It dissolves slowly, releasing a substance to lubricate your eye.

• Tear-stimulating drugs – Available as pills, gel or eye drops, cholinergic (pilocarpine, cevimeline), these help to increase tear production.

• Autologous blood serum drops – For serious dry eye that’s not responding to other treatment, these eyedrops are made with a sample of your blood. It’s processed to remove the red blood cells and then mixed with a salt solution.

Myopia is a very common condition around the world, but its prevalence does not mean it should be taken lightly. Myopia is linked to several serious eye diseases that can permanently threaten vision, including myopic maculopathy, certain types of retinal detachment, and some forms of glaucoma.

What Is Myopia?

Myopia (or nearsightedness) is so common that nearly 50% of North Americans will have myopia by 2030. Myopia happens when the eye grows too fast, too long, and gets weaker. You may know it as blurry vision far away. At our practice, we specialize in pediatric eye care and treat myopia seriously.

Myopia can develop as young as age 3, and it often gets worse as children grow. Parents may not see signs that their child has myopia, such as squinting or having to sit up close to the television or computer screen to see clearly. Children often don’t realize their vision is blurry.

The heavy use of digital devices is not going away and certainly is not helping things. It is important to have your child take breaks that are at least 5 minutes long, at least once an hour. Children should also spend at least 90 minutes outside a day.

The younger your child, the faster their myopia tends to progress. Early and regular pediatric eye exams are essential for detecting myopia as soon as possible. Treating it early can help slow its progression and reduce the risk of serious eye health issues later in life.

Myopia Can Affect More Than Just Your Eyes

Myopia can affect your child’s ability to perform well in school, sports, performing arts, and other activities that require clear vision. Controlling myopia progression will free them up to be at their best.

If you believe that your child may have myopia, contact our office to schedule a pediatric eye exam - this is the best first step to take.

Over the years, contact lenses have evolved. A new product called MiSight is giving children a new and improved option. MiSight lenses effectively treat myopia, otherwise known as nearsightedness.

Myopia

Myopia is the medical term used for nearsightedness. Of all correctable visual impairments, myopia ranks number one. With this condition, the eye grows too long from the front to the back. As a result, images don’t focus on the retina. Instead, they focus at the front of it. With this refractive error, individuals can see things up close without any problem but everything at a distance appears blurry. Over time, myopia in children typically worsens. This refractive error puts them at risk of developing other problems. For example, they’re more prone to having premature cataracts and detached retinas as an adult.

To treat this condition, most opt for prescription eyeglasses or contacts. Although MiSight Lenses work similarly to conventional lenses, they’re unique.

Benefits of MiSight Lenses

These contacts slow the progression of myopia in children between the ages of eight and 12. Even more exciting, they slow the progression by as much as 59%. For instance, if an ophthalmologist or optometrist diagnoses a child with nearsightedness and predicts a diopter of -8.00, MiSight contact lenses can reduce that to about -3.50.

As the only contact lens on the market capable of doing this, the Food and Drug Administration (FDA) fully approved them in 2019.

Another benefit of wearing MiSight contacts over traditional lenses is their soft lens. Especially for younger wearers, they provide optimal comfort.

Also, an individual only wears them once before discarding them. It’s important to note that these contacts aren’t made for overnight wear. For that reason, users need to remove them from the eyes and discard them at the end of each day.

The eye is a very delicate and fragile part of the body. According to one study on distance vision, about 188.5 million individuals are said to suffer from mild vision impairment, 217 million individuals suffer from moderate and severe impairment while 36 million individuals are blind. For near vision impairment, there are about 826 million individuals suffering. In all, there are about 1.3 billion people living with one of these impairments.

While a lot of people are aware that the eyes are an integral part of the body system, most of them do not pay very close attention to taking care of their eyes and are, in essence, taking it for granted. As the saying goes, “You don't know what you have until it's gone," and therefore, we have decided to take the necessary steps to provide you with information on how to best to take care of your eyesight.

Below are ways to keep your eyes safe:

1. Eat Healthy

Eating a healthy diet is a very integral part of keeping the eyes healthy. Nutrients like lutein, vitamins E and C, omega-3 fatty acids, and zinc may help in preventing eye-related problems like cataracts and macular degeneration. These nutrients can be found in vegetables like collards, kale, spinach, fish like tuna, salmon, and halibut, as well as in beans, nuts, eggs, oranges, pork, and oysters.

Besides eating meals rich in nutrients, it is equally important to eat a well-balanced diet. Obesity can cause diabetes and other medical conditions, leading to blindness or glaucoma. Obesity is also regarded as the chief cause of blindness across the globe which should raise a red flag to watch your weight. You can always visit your doctor to get help with drafting a healthy eating plan.

2. Know your family's medical history

Eye issues are usually hereditary which is why it is important to collect a family history on any diseases that may affect eye health and then report them to your eye doctor. This will help to determine your chances of any future eye conditions as well as come up with an action plan for future eye exams.

3. Avoid Smoking

Smoking, in general, is harmful to your overall health. In regards to your eyes, it can cause macular degeneration, destroy the optic nerve, and cause cataracts. It can even lead to vision loss. Quitting smoking if you already smoke, or better yet, not even starting, will be extremely beneficial to your overall health and wellness.

4. Wear Sunglasses

Sunglasses are more than just fashion accessories, they are vital in protecting the eyes from ultraviolet rays emitted from the sun. UV rays can cause macular degeneration and even cataracts which is why it is important to wear sunglasses that protect against 99% -100% of UV rays.

5. Obey workplace safety precautions

It is important we wear protective eye gears when engaging in sporting activities or jobs that could be harmful to the eyes. Such eyewear includes safety goggles, glasses, and helmets. Most of these protectors are from polycarbonates, which is a much stronger material than plastic.

6. Rest your eyes

Just like our bodies, the eyes also need rest to perform optimally. Depriving yourself of adequate sleep and rest can have an adverse effect on the eyes. During the use of the computer, remember to rest the eyes for at least 20 seconds after every 20 minutes by looking away from the screen. Doing this will reduce eye strain.

7. Visit your eye doctor regularly

Getting regular eye exams is one of the most important things you can do for your eye health. Conditions like glaucoma are much easier to treat if they are discovered early so don’t stay far from your doctor. 

As our bodies age, it is normal to notice that there are decreases in our ability to complete certain functions that may have been natural for us in our youth. Just like our physical strength, the strength of your eyes can also weaken over time.

Several different factors influence how each of us will experience aging. Your genetics can play a pivotal role. Understanding your family history and making sure to communicate this with your health professional can be a great way to monitor changes and spot early signs and symptoms. Exposure to certain chemicals or environments or specific trauma to our eyes can also have an impact on how our eyes age. While the eyes can often recover from traumatic injury or exposure, they may still have a detrimental effect on your vision as you age.

Knowing what age you start to have an increased risk of certain diseases or eye conditions can help you to be prepared when you meet with your optometrist. Here are some of the most common ailments that people experience when they age.

Presbyopia

Once you are over 40 years old you may experience a loss in vision at close range. Presbyopia is a normal condition that occurs due to the hardening of the lens in your eye. In the early stages, you can often compensate for small changes to your vision, but as the condition progresses, you will likely need a corrective lens, or choose a surgical procedure. such as Lasik, corneal inlays, refractive lens exchange, and conductive keratoplasty.

Cataracts

Cataracts are technically a disease of the eye. However, they are so frequently seen in patients as they age, that they are classified as a normal part of aging. While almost half of the population over 65 have cataracts, that number increases even more by age 70. While it can be frightening to begin losing your vision, cataract surgery is extremely successful and can restore up to 100% of the lost vision. If you notice even small changes to your vision, it is smart to talk to your doctor. Cataract surgery is best performed when the cataracts are small and can be more easily removed.

Macular Degeneration

This disease is the leading cause of blindness in senior citizens in the United States.

Glaucoma

The risk of developing glaucoma generally begins when you are in your 40’s with a near one percent chance and increases throughout the decades with a twelve percent by the time you are in your 80’s.

Diabetic Retinopathy

Individuals who have diabetes may be affected by diabetic retinopathy. This disease occurs when blood sugar levels are elevated for an extended period that causes damage to the eye. This damage may lead to permanent vision loss. Americans with diabetes over the age of 40 are at an increased risk, with about 40 percent of people with diabetes over this age displaying some degree of diabetic retinopathy.
 

Contact lenses come in a variety of shapes and styles to suit the range of needs for individual patients. What this means is that there is almost certainly a type of contact lens that will both feel comfortable for you and improve your vision. 

Some types of contact lenses are known as speciality lenses. This is because they are designed specifically to overcome some eye issues which may prevent a patient from wearing the most common and generic styles of contact lenses. In fact, speciality contact lenses have transformed the vision options of many patients who would otherwise have only had the choice between wearing glasses or undergoing laser vision correction. There are numerous types of speciality contact lens, including scleral lenses.

What are scleral lenses?

Scleral contact lenses get their name from the fact that, unlike regular contacts, they vault over the entire corneal surface and rest on the white part of the eye, which is called the sclera. This makes them larger than standard contacts, which in turn provides a variety of benefits. Their size makes them easier to handle and more stable when on the eye, which in turn provides the patient with sharper and more reliable vision. They are also less likely to become dislodged and come out. 

Scleral contact lenses are also gas permeable, which means that oxygen can pass right through them and reach the surface of the eyes. This is important for comfort, particularly for patients who experience dry eyes. The gap that is created between the back of the contact lens and the front surface of the eye can also trap tear film, acting as a fluid reservoir which will keep the eyes moist and healthy. 

Types of scleral lenses

Within scleral lenses there are several different sizes to choose between. These are based on where the lenses meet the surface of the eye and are as follows:

• Full scleral lenses: the largest type, they provide the greatest amount of clearance between the cornea and lens and rest on the outer sclera. 

• Mini scleral lenses: the mid-size variety, make contact with the eye on the anterior sclera. 

• Semi-scleral lenses: although larger than conventional lenses, they are not huge, and the edge of the contact lens rests on the junction between the cornea and the sclera. 

Your scleral lens provider will be able to make a recommendation as to the correct size for you, which will be based on your individual requirements. 

Many patients come to us every day struggling to get through their daily lives with their current choice of vision correction. Some have eyeglasses that do not sit properly on their face or feel that their peripheral vision is hindered by the frames. While contact users may find the lenses uncomfortable or have them fall out at inconvenient times. For these patients, we are pleased to offer orthokeratology, or Ortho-K, a revolutionary way to help you see clearly throughout the day without having to wear glasses or contacts and without having to get laser eye surgery.

What is Ortho-K?

Generations ago, eye doctors knew that the tissue in the eye was soft and somewhat malleable. This knowledge caused them to wonder if they could push the eye back into the proper shape, would an individual be able to see clearly even if they were not wearing their prescription lenses. With the development of gas permeable contact lenses, a few eye doctors began to notice that their patient’s prescriptions did not change as rapidly as previously noted and that they appeared to be able to see correctly even when they were not wearing their contacts.

From these early discoveries, the world of Ortho-K was born. Ortho-K is a special treatment to help patients see clearly even when they are not wearing a prescription lens. Instead, a special gas permeable contact lens is placed into the eye each night before bed and the lens gently pushes the eye into the proper shape while you sleep. In the morning, you can remove the lenses and still see clearly throughout the day. Some patients can even see clearly for up to three days after wearing them for just one night!

Who Should Consider Ortho-K?

• There are a number of issues that our patients can have with prescription lenses. If you have one of the following conditions or concerns, call our office today to schedule an appointment.

• Allergies to the materials in contact lenses

• Dry eye that is made worse by wearing prescription lenses

• Dirt or other debris that gets under contact lenses

• You play sports and do not want to worry about glasses or contacts

• The ability to wake up at night and see clearly

• A general dislike of glasses or contacts
