Dry Eye has reached epidemic proportions globally. Without proper assessment, treatment can be hit and miss. The Eye Practice prides itself in having the most advanced Dry Eye Clinic in Australasia. In the last 5 years we have had an explosion of new information on dry eyes.
As one of the most experienced optometrists in Sydney focusing on dry eyes, we travel the world to keep up to date with the latest and best dry eye treatments. It is no wonder that so many of our patients will travel from Melbourne, Adelaide, Perth, Brisbane and even Auckland to try and bring their dry eyes under control and get their life back.
It is very important to understand that the condition does not just appear over night. It takes years to develop to the point where it is debilitating for some people.
How hard could dry eye management be?
Many optometrists or ophthalmologists take the attitude that "if the eye is dry, then we need to wet it!" Unfortunately it is not that simple. In fact the so called mainstay of its treatment is lubricating eye drops, which believe it or not when used too frequently or inappropriately can actually make dry eyes worse!
Dry Eye disease or dry eye syndrome happens when the lubrication system of the eye breaks down. This can occur for many reasons, which is why dry eye is often referred to as a multifactorial disease.
Your eye is lubricated by your tear film. This sounds simple, but has been analysed by scientists and is extremely complex! NO eye drop on this planet can mimic the human tear film properly, which is why it takes more than dry eye drops to treat dry eyes.
Human tears are primarily made up of an aqueous (watery) component. This is produced by the lacrimal gland, which sits just under your eyebrow. This aqueous layer is mainly salty water. When the water evaporates in dry eye syndrome, the tear film becomes even saltier, which can cause the burning sensation that many people complain about.
Tears are just water, right?
Wrong! Your watery tears are packed with amazing little molecules that protect your eye from invading microbes. These little guys also control inflammation in the eye. There are two other very important components of the tear film, which are meibum and mucous.
The meibum is the oily layer and is produced by a row of glands called meibomian glands in the eye lids. When this oil is in short supply a condition known as meibomian gland dysfunction results. A recent study showed that at least 80% of dry eye patients had some form of meibomian gland dysfunction. Think of meibum as engine oil. If the oil is insufficient or old, the lubrication of the engine suffers and damage can occur.
Last but not least is the mucous layer of the tear film. This serves to anchor the tear film to the eye. Without a healthy mucous layer the tears cannot lubricate the eyes properly and this leads to significant discomfort.
Please make sure you do not miss the short video below, which explains dry eyes and its problems in a simple but logical way.
Symptoms include burning, grittiness, pain, irritation, redness, and inflamed or flaky eyelids (blepharitis). A feeling like an eyelash being caught in the eye or a grain of sand is also common. Paradoxically watery eyes (also called epiphora) can be a symptom of dry eyes. How could this be? The premise is that once the eyes have become dry, the lacrimal gland goes into over drive trying to self correct the tear film imbalance. Unfortunately this is not a particularly effective mechanism, as the eyes flood with tears and they in turn flush out the oil and the mucous, which is also so important in protecting the ocular surface.Learn more about dry eye symptoms
Causes of Dry Eyes
Studies show that over 80% of dry eye disease is caused or worsened by Meibomian Gland Dysfunction - a problem with the oily tear glands situated in the eyelids. Some medications can be culprits, but we must not forget the addictive use of digital devices such as the iPhone. In our extensive experience we have noticed an exponential increase in dry eye disease, even in teenagers. Constantly staring at these back lit gadgets causes atrophy in the blinking muscle of the eye lids, which in turn allows excessive air to continually irritate the eyes.
Other more obscure causes can be lagopthalmos, which often happens when we sleep. Auto immune diseases such as rheumatoid arthritis and Sjogren's syndrome cause inflammation in the whole body, which in turn can inflame and shut down the lacrimal gland.Learn more about the causes of dry eyes
