WHAT IS GLAUCOMA?

Glaucoma is a condition that causes damage to your eye’s optic nerve and gets worse over time. It’s often linked to a buildup of pressure inside your eye. Glaucoma tends to be inherited and may not show up until later in life.

The increased pressure, called intraocular pressure, can damage the optic nerve, which transmits images to your brain. If the damage continues, glaucoma can lead to permanent vision loss. Without treatment, glaucoma can cause total permanent blindness within a few years.

Most people with glaucoma have no early symptoms or pain. You need to see your eye doctor regularly so she can diagnose and treat glaucoma before long-term visual loss happens.

If you’re over age 40 and have a family history of the disease, you should get a complete eye examfrom an eye doctor every 1 to 2 years. If you have health problems like diabetes or a family history of glaucoma or are at risk for other eyediseases, you may need to go more often.

What Causes Glaucoma?

It’s the result of an intrinsic deterioration of the optic nerve, which leads to high fluid pressure on the front part of the eye.

Normally, the fluid, called aqueous humor, flows out of your eye through a mesh-like channel. If this channel gets blocked, the liquid builds up. The reason for the blockage is unknown, but doctors do know it can be inherited, meaning it’s passed from parents to children.

Less common causes include a blunt or chemical injury to your eye, severe eye infection, blocked blood vessels inside the eye, and inflammatory conditions. It’s rare, but sometimes eye surgery to correct another condition can bring it on. It usually affects both eyes, but it may be worse in one than the other.

What Are the Types of Glaucoma?

There are two main kinds:

Open-angle glaucoma. It’s the most common type. Your doctor may also call it wide-angle glaucoma. The drain structure in your eye — it’s called the trabecular meshwork — looks normal, but fluid doesn’t flow out like it should.

Angle-closure glaucoma. It’s less common in the West than in Asia. You may also hear it called acute or chronic angle-closure or narrow-angle glaucoma. Your eye doesn’t drain right because the drain space between your iris and cornea becomes too narrow. This can cause a sudden buildup of pressure in your eye. It’s also linked to farsightedness and cataracts, a clouding of the lens inside your eye.

Who Gets Glaucoma?

It mostly affects adults over 40, but young adults, children, and even infants can have it. African-Americans tend to get it more often, when they’re younger, and with greater vision loss.

You’re more likely to get it if you:

  • Are of African-American, Irish, Russian, Japanese, Hispanic, Inuit, or Scandinavian descent
  • Are over 40
  • Have a family history of glaucoma
  • Have poor vision
  • Have diabetes
  • Take certain steroid medications, like prednisone
  • Have had trauma to the eye or eyes

What Are the Symptoms?

Most people don’t have any. The first sign is often a loss of peripheral, or side, vision. That can go unnoticed until late in the disease. That’s why glaucoma is often called the “sneak thief of vision.”

Detecting glaucoma early is one reason you should have a complete exam with an eye specialist every 1 to 2 years. Occasionally, pressure inside the eye can rise to severe levels. In these cases, you may have sudden eye painheadache, blurred vision, or the appearance of halos around lights.

If you have any of the following symptoms, seek immediate medical care:

  • Seeing halos around lights
  • Vision loss
  • Redness in the eye
  • Eye that looks hazy (particularly in infants)
  • Nausea or vomiting
  • Eye pain
  • Narrowed vision (tunnel vision)

How Is It Diagnosed?

Your eye doctor will use drops to open (he’ll call it dilate) your pupils. Then he’ll test your vision and examine your eyes. He’ll check your optic nerve, and if you have glaucoma, it will look a certain way. He may take photographs of the nerve to help him track your disease over time. He’ll do a test called tonometry to check your eye pressure. He’ll also do a visual field test, if necessary, to figure out if you’ve lost your side, or peripheral, vision. Glaucoma tests are painless and take very little time.

How Is Glaucoma Treated?

Your doctor may use prescription eye drops, laser surgery, or microsurgery to lower pressure in the eye.

Eye drops. These either reduce the formation of fluid in the eye or increase its outflow, thereby lowering eye pressure. Side effects may include allergies, redness, stinging, blurred vision, and irritated eyes. Some glaucoma drugs may affect your heart and lungs. Be sure to tell your doctor about any other medications you’re taking or are allergic to.

Laser surgery. This procedure can slightly increase the flow of the fluid from the eye for people with open-angle glaucoma. It can stop fluid blockage if you have angle-closure glaucoma. Procedures include:

  • Trabeculoplasty: Opens the drainage area
  • Iridotomy: Makes a tiny hole in the iris to let fluid flow more freely
  • Cyclophotocoagulation: Treats areas of the middle layer of your eye to reduce fluid production

Microsurgery. In a procedure called a trabeculectomy, the doctor creates a new channel to drain the fluid and ease eye pressure. Sometimes this form of glaucoma surgery fails and has to be redone. Your doctor might implant a tube to help drain fluid. Surgery can cause temporary or permanent vision loss, as well as bleeding or infection.

Open-angle glaucoma is most often treated with various combinations of eye drops, laser trabeculoplasty, and microsurgery. Doctors in the U.S. tend to start with medications, but there’s evidence that early laser surgery or microsurgery could work better for some people.

Infant or congenital glaucoma — meaning you are born with it — is primarily treated with surgery, because the cause of the problem is a very distorted drainage system.

Talk to your eye doctor to find out which glaucoma treatment is right for you.

Can You Prevent Glaucoma?

No. But if you diagnose and treat it early, you can control the disease.

What’s the Outlook?

At this time, lost vision can’t be restored. However, lowering eye pressure can help preserve the sight you have. Most people with glaucoma who follow their treatment plan and have regular eye exams don’t go blind.

Sweet sleep: Dealing with and overcoming sleep disorders – by Anna Kucirkova

Sleep.

We often take it for granted, expecting that every night we’ll drift into sweet slumber. But for millions of people around the world, sleep is a challenge. Due to sleep disorders, they find themselves unable to sleep, or worse.

But what exactly are sleep disorders? And what causes them?

In this post, we’re going to break down both the what and why of sleep disorders, as well as explain the effects of lack of sleep on the human body.

Ready? Let’s dive in.


What Is A Sleep Disorder?

Put simply, a sleep disorder is a change in the way you sleep. Instead of sleeping well and getting a good night’s rest, new, unhealthy sleep patterns are introduced into your life, altering the very fabric of your sleep.

Sleep problems are widespread, with approximately 10-20% of people saying that they struggle with significant sleep problems, and another 33% of adults reporting insomnia-like symptoms.

Sleep disorders can be grouped in a variety of ways, including difficulty falling asleep, feeling extra sleepy during the day, having trouble breathing at night, problems with your natural sleep-wake cycles, and behaviors at night while sleeping.

How do you know if you have a sleep disorder? There are some common symptoms that are signs that something is greatly amiss with your sleep:

  • Excessive sleepiness during the day
  • Irregular breathing patterns at night
  • Irregular movements at night
  • Difficulty falling asleep

If you struggle with any of these symptoms, there is a good chance that you’re struggling with some form of sleep disorder.


What Are Some Common Sleep Disorders?

There are a variety of common sleep disorders which affect millions of people around the world.

These disorders include:

Insomnia

Perhaps the most well-known of all sleep disorders, insomnia is characterized by the inability to either fall asleep or stay asleep, resulting in a person getting insufficient sleep.

For most people with insomnia, it takes more than 20-30 minutes to fall asleep (or fall back asleep). If this happens at least three times per week for more than three months it is called “chronic insomnia”.

Approximately 10% of all adults are officially diagnosed with insomnia, making it the most common sleep disorder.

Insomnia is often treated with either Cognitive Behavioral Therapy or medication.

Sleep Apnea

Sleep apnea is an extreme form of snoring. It is a chronic medical condition in which a person stops breathing repeatedly while they are sleeping. This stoppage of breath can last 10 seconds or more and can cause both oxygen levels to drop and the person to temporarily awake from sleep.

Typically, sleep apnea is caused by one of two things. First, it can be the result of an obstruction of the upper airway. This is called “obstructive sleep apnea”. It can also be caused by the brain itself failing to initiate breathing, which is called “central sleep apnea”.

If left untreated, the health effects of sleep apnea can be significant, including:

All of these are in addition to the extreme sleepiness which sleep apnea typically causes.

Sleep apnea is typically treated with a CPAP device, which forces a steady stream of air into a person’s nose to ensure that they keep breathing.

Restless Leg Syndrome

Sleep Apnea

Restless leg syndrome (RLS) is a disorder in which the person feels the need to constantly move while in bed, particularly their legs. People often describe the sensation as aching, burning, tingling, or even feeling like bugs are crawling on their legs. These symptoms can make it extremely difficult to fall asleep and stay asleep.

There are many causes of restless legs, including pregnancy, iron deficiency, and obesity.

RLS can be treated through exercise, a reduction in caffeine or alcohol, and in severe cases, medication.


Circadian Rhythm Disorders

Your circadian rhythm is your body’s internal clock, telling you when to wake up and when to go to sleep. Circadian rhythm disorders occur when a person’s internal clock is out of sync with the external world.

For example, being wide awake at 2:00 AM may indicate that your circadian rhythm has gotten out of sync with the light-dark cycle.

Typically, these disorders happen due to shifting work, jet lag, advanced or delayed sleep phase syndrome, or blindness. The mismatch between the circadian rhythm and the external cues can result in insomnia or extreme sleepiness.

Circadian rhythm disorders can be treated with medication or natural supplements such as melatonin.


Parasomnias

Parasomnias are sleep disorders characterized by strange, abnormal sleep behaviors. These behaviors can be complex and are done unconsciously, as the person is fully asleep. These behaviors can include everything from sleep terrors to sleepwalking to sleep eating to even sleep sex.

There can be a number of underlying causes, including sleep apnea. Thankfully, these disorders can often be treated with medications such as melatonin or clonazepam.


Sleep Paralysis

Sleep paralysis involves the temporary inability to move as a person moves from sleep to wakefulness or vice versa. This temporary feeling of paralysis can be quite frightening and often involves hallucinations as well. The disorder is common, with around 25% of people experiencing it at least once.

If necessary, sleep paralysis can be treated with medication.


Narcolepsy

There are four symptoms typically associated with narcolepsy:

  • Excessive sleepiness during the day
  • Cataplexy (the sudden loss of muscle tone in response to a particular stimulus such as laughter or surprise)
  • Sleep paralysis
  • Hypnagogic hallucinations (very vivid hallucinations)

The result of these symptoms can be a person seemingly falling asleep in an instant at any point in time.

Narcolepsy is most often treated with medications.

Chronic Fatigue Syndrome

Chronic Fatigue Syndrome (CFS) is an ongoing, unexplained fatigue that is not lessened by rest or sleep. It may be worsened through physical or mental activity, and the results can be extreme, causing a person to be practically incapacitated.

The fatigue can be so extreme that a person is forced to adapt their daily schedule so that they can preserve as much energy as possible.

Before a person can be diagnosed with CFS, other underlying causes, such as sleep apnea, must be ruled out.


What Are The Effects Of Lack Of Sleep?

There are numerous detrimental effects of lack of sleep.

  • Not getting enough sleep can cause you to have memory problems. Sleep is essential to forming memories and not getting enough sleep can affect both your long-term and your short-term memory.
  • Sleeplessness can also result in difficulty concentrating and problem-solving.
  • Mood changes are a common side effect of lack of sleep. When you don’t get enough sleep, your emotions are on a hair-trigger and can lead to depression or anxiety.
  • If you sleep less than five hours per night, your risk of high blood pressure greatly increases.
  • A lack of sleep is detrimental to your immune system, making you much more vulnerable to viruses that cause the common cold and the flu.
  • Weight gain is a common side effect of not getting enough sleep. When you’re sleep-deprived, your brain doesn’t send the normal signals to your body that you’re full, resulting in overeating.
  • Many people who don’t sleep enough find themselves experiencing a low sex drive. In men, this may be caused by a drop in overall testosterone levels.
  • A lack of sleep can affect your body’s ability to control insulin levels, which is a blood-sugar-lowering hormone. Those who don’t get enough sleep often have higher levels of blood sugar, which can eventually result in Type-2 diabetes.
  • When you don’t get enough sleep, your balance and coordination are affected, making you much more prone to falling.

Don’t Neglect Your Sleep
