Dr Samantha Bradley, Head of Professional Relations and Medical Marketing, RB UK Ltd.

The accompanying article has been dispatched, advised and completely supported by RB.

Liposomal splashes are particularly intended to address evaporative dry eye (EDE) side effects. EDE represents roughly 80 percent of dry eye cases[1], with around 20 percent experiencing watery lacking dry eye[1].

Be that as it may, the method of activity and technique for utilization of liposomal showers are not in every case surely knew, specifically, it very well may be entangled to clarify how a liposomal splash achieves the surface of the eye subsequent to being connected to a shut eyelid.

This article is planned to enable drug specialists to comprehend and pass on the advantages of liposomal splashes to sufferers of dry eye, by considering their method of activity in connection to the adjustment of the tear film.

What are liposomal splashes? 

Liposomal showers, as OptrexTM ActiMistTM, contain soy lecithin, a phospholipid, which is typified inside minuscule circular liposomal vesicles. Soy lecithin is an emulsifier, which because of its bipolar nature empowers the water and oil layers of the eye to cooperate.

How do liposomal splashes function?

In 80 percent of individuals with dry eye, the reason is insufficiency or precariousness of the lipid layer of the tear film[1] which ordinarily goes about as a seal for the watery fluid layer, keeping it from vanishing.

Tear Film Layers


Three fundamental layers make up the typical tear film. In 80% of individuals with dry eye, the reason is insufficiency or flimsiness of the lipid layer

The tear film lipid layer is comprised of two stages: a thick external nonpartisan layer in contact with the air, and a more slender polar layer made up for the most part of phospholipids which frames an interface with the tear film watery layer. It is this phospholipid layer which encourages spreading of the external lipid layer. Research has demonstrated that people without a noticeable lipid layer, or with a nonconfluent lipid layer, show a four-overlay higher rate of tear film evaporation.

Nonetheless, an investigation has uncovered that the utilization of liposomal splashes results in a clinically and critical increment in lipid layer thickness and tear film dependability following application, while another infers that treatment with phospholipid liposomes demonstrates factually noteworthy clinical points of interest with better outcomes in the top parallel conjunctival overlay (LIPCOF) test, destroy film break time (BUT), Schirmer-I test, tear meniscus estimation, irritation of the cover edges, and visual sharpness, contrasted with customary counterfeit tears treatment.

The liposomal shower conveys phospholipid to the eye, fixing the lipid layer, in this way tending to the lipid unsteadiness that causes EDE. The splash ought to be connected to the shut eyelid from about 10cm away (see figure 2). The eyelids ought to be kept shut a while later to empower the phospholipid liposomes to settle on the eyelid, where they warm up and begin to move towards the edge of the eyelids. When they achieve the edge of the eyelid, squinting disseminates the liposomes over the watery layer of the tear film, creating moment relief.

Investigation into the activity of liposomal showers blended with a fluorescein color arrangement onto shut tops outlines how the splashed on arrangement achieves the top edges and the tear film inside a couple of minutes. After application to shut tops, and just a couple of squints, fluorescein is unmistakable in the tear meniscus.

This is like what happens normally when lipids are discharged from the meibomian organs (see figure 3) on to the top edges where they frame a store. Squinting puts weight on the meibomian organs, bringing about a little measure of oil being communicated onto the top edges, and the lipids that were a piece of the tear film blend by and by with the lipid store on the cover edge. Amid the opening of the tops, a portion of the lipids from this store spread onto the tear film, framing a lipid layer.

 Meibomian organs


In evaporative dry eye, the meibomian organ (imagined inset) neglects to emit enough oil to keep up the lipid layer of the tear film

The showered on phospholipid liposomes achieve the top edges through a similar impact and blend with the endogenous lipids to help fix the tear film lipid layer.

What are the advantages of liposomal showers? 

Dissimilar to liposomal showers, numerous watery fake tear visual oils, which are usually used to treat dry eye manifestations, are not particularly intended to address the disturbed lipid layer in EDE; rather, they briefly bathe the eye creating transient symptomatic alleviation and can require visit application.

Liposomal splashes help balance out the external lipid layer[1] to facilitate the bothering and inconvenience of evaporative dry eye. They give moment help and last to up to four hours[1],[4], which means they should be connected less every now and again than some dry eye items.

Liposomal showers are additionally helpful, as they can be utilized by individuals who wear contact focal points, and as a result of the liposome detailing, they won't smear cosmetics. Besides, they can be valuable for patients with coordination issues, or smoothness issues or for the individuals who simply think that its hard to utilize drops. In contrast to many eye arrangements, when opened, they have an expiry of up to a half year and Optrex ActiMist is bundled in a fixed container with a non-vented pump.

Network drug store job 

Around 40% of network drug stores see no less than one patient a day* who has a worry about their eyes and studies demonstrate that up to 30 percent of the populace beyond 50 a years old dry eye indications on an ordinary basis[5].

In spite of this, a 2016 review of pharmacists*, demonstrated that two out of three respondents were unconscious that there are diverse sorts of dry eye condition, which have distinctive etiology, and hence required diverse administration.

By suggesting liposomal splash for the treatment of EDE, disclosing how to utilize it and critically, how it works when showered on shut eyes, drug specialists can assist contribute with ensuring patients get a treatment that is suitable, worthy and will help mitigate the indications of dry eye.

Glaucoma Wiki - Everthing About Glaucoma Disease

Glaucoma
Glaucoma is the name given to a group of eye diseases in which the optic nerve at the back of the eye is slowly destroyed. In most people this damage is due to an increased pressure inside the eye - a result of blockage of the circulation of aqueous, or its drainage. In other patients the damage may be caused by poor blood supply to the vital optic nerve fibres, a weakness in the structure of the nerve, and/or a problem in the health of the nerve fibres themselves.

Over 300,000 Australians have glaucoma. While it is more common as people age, it can occur at any age. As our population becomes older, the proportion of glaucoma patients is increasing.

Glaucoma Causes & Symptoms

Chronic (primary open-angle) glaucoma is the most common type. It has no symptoms until eye sight is lost at a later stage.

Damage progresses very slowly and destroys vision gradually, starting with the side vision. One eye covers for the other, and the person remains unaware of any problem until a majority of nerve fibres have been destroyed, and a large part of vision has been destroyed. This damage is irreversible. It is progressive and usually relentless. Treatment cannot recover what has been lost. But it can arrest, or at least slow down, the damage process. That is why it is so important to detect the problem as early as possible, to be able to start treatment with as little damage to the vision as possible.


  • normal vision
  • mild to moderate loss
  • severe visual loss


Glaucoma Risks

Although anyone can get glaucoma, some people have a higher risk, i.e. those with:


  • a family history of glaucoma;
  • diabetes;
  • migraine;
  • short sightedness (myopia);
  • long sightedness (hyperopia);
  • eye injuries;
  • high blood pressure; or
  • past or present use of cortisone drugs (steroids).

People in these groups should have their first eye check no later than the age of 35. For most people, it is recommended to have an eye check for glaucoma by the age of 40.

Glaucoma Types

Chronic (primary open-angle) glaucoma

This is the most common form of this disease. However, other forms occur.

Low-tension or normal tension glaucoma

Occasionally optic nerve damage can occur in people with so-called normal eye pressure. This form of glaucoma is treated in the same manner as open-angle glaucoma.


Acute (angle-closure) glaucoma


Acute glaucoma is when the pressure inside the eye rapidly increases due to the iris blocking the drain. An attack of acute glaucoma is often severe. People suffer pain, nausea, blurred vision and redness of the eye. Immediate medical help should be sought. If treatment is delayed there can be permanent visual damage in a very short time. Usually, laser surgery performed promptly can clear the blockage and protect against visual impairment.

Mild to moderate loss

Congenital glaucoma
This is a rare form of glaucoma caused by an abnormal drainage system. It can exist at birth or develop later. Parents may note that the child is sensitive to light, has enlarged and cloudy eyes, and excessive watering. Surgery is usually needed.

Secondary glaucomas
These glaucomas can develop as a result of other disorders of the eye such as injuries, cataracts, or eye inflammation. The use of steroids (cortisone) has a tendency to raise eye pressure and therefore pressures should be checked frequently when steroids are used.

How is glaucoma detected?
Regular eye examinations are the best way to detect glaucoma early.

A glaucoma test usually includes the following:


  • optic nerve check with an ophthalmoscope;
  • eye pressure check (tonometry);
  • visual field assessment if needed — this tests the sensitivity of the side vision, where glaucoma strikes first.

Can glaucoma be treated?
Although there is no cure for glaucoma it can usually be controlled and further loss of sight either prevented or at least slowed down.

Glaucoma Treatments


Glaucoma Eyedrops - these are the most common form of treatment and must be used regularly. In some cases pills are prescribed. The drops can be varied to best suit the patient and the type of glaucoma.
Laser (laser trabeculoplasty) - this is performed when eyedrops do not stop deterioration in the field of vision. In many cases eyedrops will need to be continued after laser. Laser does not require a hospital stay.
Glaucoma Surgery (trabeculectomy) -  this is performed usually after eyedrops and laser have failed to control the eye pressure. A new channel for the fluid to leave the eye is created.


Treatment can save remaining vision but it does not improve eye sight.

Glaucoma Causes - Do I Have Glaucoma

The front of the eye is a D-molded chamber in which the focal point and iris (the hued part) make up the straight divider, while the cornea (the surface of the eye) frames the bended divider. An organ behind the upper eyelid fills this chamber with a reasonable fluid (watery funniness) that provisions the front of the eye with oxygen and supplements and keeps it swelled. An enduring supply of fluid is delivered, and it depletes out through a work of modest openings behind the lower eyelid, called the trabecular meshwork.

In glaucoma, the fluid is created typically however the trabecular meshwork can't deplete it because of stopping up or some other reason. Fluid weight develops in the eye, pushing on the optic nerve (the nerve that interfaces the eye to the mind). The nerve cells are then gradually choked of blood, in the long run biting the dust. The external nerves bomb first, so vision misfortune will in general begin at the edges, advancing to "exclusive focus" and visual impairment. Numerous individuals don't see this at first, and there's typically no agony, so glaucoma can be very best in class before it's identified. The US Glaucoma Establishment appraises that just half individuals with glaucoma know about the malady.



Kinds of glaucoma are arranged by what's preventing the fluid from depleting: 

Essential open-point glaucoma (POAG) is the most widely recognized type of glaucoma in North America, influencing around 1 out of 100 individuals. Individuals of African plummet are particularly powerless. It regularly strikes after the age of 50. The trabecular meshwork looks fine on examination yet doesn't deplete legitimately. A few analysts trust this is on the grounds that maturing makes the phones less effective. Others speculate a seepage issue under the eye, or another imperfection. Regardless, weight develops and the optic nerve begins to come up short. Vulnerable sides in the end show up in the fringe vision, and later in the focal "seeing" region. This harm can't be fixed. POAG deteriorates after some time in the event that it isn't dealt with.

Point conclusion glaucoma is most basic in individuals of Asian or Inuit plummet, and in ladies and farsighted individuals. It very well may be ceaseless or discontinuous. Since the trabecular meshwork is situated in the edge of the D between the iris and the cornea, anything that swells the iris or pushes it forward can close that edge, obstructing the meshwork. Certain ailments, for example, diabetes or uveitis (fiery state of the eye), can make the iris be pushed forward. Maturing additionally will in general thicken the focal point and iris, blocking fluid stream between the front and back assemblies of the eye. Weight works in the back chamber (the fundamental piece of the eyeball), driving the iris forward and shutting the trabecular meshwork.



In typical strain glaucoma, the weight in the eye is in the ordinary range, yet the optic nerve is as yet harmed. It's trusted that poor blood stream to the optic nerve makes the nerves more defenseless. Weights only somewhat better than expected can along these lines harm the eye.

Pigmentary glaucoma generally influences more youthful partially blind individuals. The iris, which is inward in nearsightedness, rubs against the shade layer that holds the eye's shading. Pieces of color rub off and stop up the trabecular meshwork, raising weight. Peeling disorder, most regular in Caucasians matured 50 and more seasoned, is comparative. Flaky white material shows up on the focal point before tumbling off to stop up the meshwork. Peeling disorder doesn't really result in glaucoma, yet it makes it multiple times more probable.

Awful glaucoma is the consequence of eye damage, regularly showing up a very long time after the occasion.
