What Causes a Stye in the Eye? Discover How It’s Treated

If you have a painful lump or swelling on your eyelid, you may have a stye. Styes are fairly common eyelid bumps and are entirely benign, though they can be a cosmetic concern for some people. Some individuals can be prone to styes, while others have never before experienced a stye on their eyelid. Keep reading to find out more about eyelid styes. 

 

What is a Stye? 

Also known as a hordeolum, symptoms of a stye include a red, painful bump on the eyelid, whether the upper or lower eyelid. It can look like a pimple on the edge of the eyelid or a sore area of swelling elsewhere on the eyelid. 

There are two types of styes – internal styes and external styes. An external stye is one that looks like the pimple at the edge of the eyelid, while an internal stye forms deeper in the eyelid tissue. Sometimes you can see a red lump on the outer skin of the eyelid, while other times, there’s no visible bump from the outside. 

 

risks eyes styes melbourneAre Styes Dangerous?

Styes of the eyelid are not cancerous but can cause some distress if they’re particularly large or sore or if you’re concerned about the appearance. Styes are not contagious and do not present a threat to your vision. 

Another bump of the eyelid that is often confused for a stye is known as a chalazion. A chalazion is a blockage of the oil glands of the eyelid, but unlike styes, chalazia do not feel sore. 

 

What Causes Styes? 

 

External Styes

External, or outer, styes are typically bacterial infections of the eyelash follicle. Though bacteria are normally found on the skin, if they overgrow within the eyelash follicle, they can result in a stye. 

Failing to wash your hands frequently and touching your eyes or using old cosmetics that have become contaminated over time can increase your risk of developing an outer stye. Certain skin conditions, such as rosacea, can also make you more likely to develop a stye. 

 

Internal Styes

An internal stye is also a bacterial infection, this time of one of the oil glands of the eyelid. These oil glands are also known as meibomian glands and are important for producing tears. 

Similar to the risk factors for an outer stye, internal styes may be more likely if you wear contact lenses or persist in using old cosmetics, and they can be associated with certain skin conditions. 

Both internal and external styes can occur either on one or both eyelids, and you can have more than one stye at a time. 

 

Treatment Options for Styes (Home Remedies and Self Care) 

 

Warm Compresses

Most styes will self-resolve in a matter of days to a week without any treatment. However, you may find that applying warm compresses (that is, a warm washcloth or other clean cloth soaked in warm water) to the closed eyelid several times a day can help the stye heal more rapidly. When preparing the warm compress, ensure that the hot water is not so hot that it causes burns or pain to your delicate eyelid skin. 

You can also try gently massaging your eyelid, however, it’s important to never try to pop or burst a stye as this can cause damage to your eyelid anatomy and cause further spread of the bacterial infection. 

 

Keep the eye area clean 

You can do this by wiping away any eye discharge using a clean cotton ball or face towel soaked with warm water, but always remember to wash your hands before touching your eyelids.

While recovering from a stye, avoid wearing contact lenses, wash your hands often, and stay away from eye makeup, as this can cause further irritation to the affected eyelid gland. 

Avoid touching the stye as much as you can.  

 

Further Management

While most styes will heal on their own, some people will need to see a doctor for further intervention. 

 

 

When to See a Doctor

You may consider visiting your optometrist or ophthalmologist if:

  • The stye is not improving within a few days, and symptoms persist
  • The eyelid skin around the stye is becoming increasingly painful or red or swelling further as time passes
  • Your entire eyelid experiences painful swelling
  • The stye is so large that it interferes with your vision 
  • You associate other symptoms with the stye, such as fever, headache, and nausea

Though a stye is usually easily diagnosed, sometimes other lesions of the eyelid can be mistaken for a stye. If you experience symptoms such as ulceration or flaking skin around the bump, or if the nearby eyelashes fall out, see your eyecare professional immediately. 

 

Antibiotics to Treat a Stye 

The use of antibiotics for a stye can be controversial; using warm compresses is generally the first-line treatment. 

Though there is little evidence that antibiotics are useful treatment options for styes, some doctors still prescribe antibiotic ointment to be applied to the edge of your eyelid where the outer stye is or oral antibiotics if it’s an internal stye or a stye at risk of turning into a wider-spread infection (a medical emergency).  

 

Surgery for a Stye

If your internal stye is taking a long time to resolve, your eye doctor may recommend it be surgically removed. This involves making a small incision and draining the contents of the stye. 

 

How to Prevent Styes

Some people are more prone to developing a stye compared to others. Though following these suggestions can reduce your risk of a stye, they are not guaranteed to prevent styes entirely.  

 

treatment management stye eye melbourneManage Medical Conditions

Medical conditions that are associated with an increased risk of a stye include:

  • dry eyes 
  • blepharitis
  • diabetes
  • excessively oily skin  

 

Steps to Prevent Styes

  • Adhering to good hygiene with your contact lenses
  • Discarding eye makeup every three months
  • Washing your hands before touching your eyes 

Some people with dry eyes or blepharitis may also find it beneficial to regularly apply a warm compress to their closed eyelid long-term.

Retinal Vein Occlusion Treatment — All You Need To Know

A retinal vein occlusion is a medical term to describe a blockage of one of the blood vessels of the retina. Being such a metabolically active tissue, the retina requires a high oxygen and energy demand. This makes retinal vein occlusions a potential medical emergency with a risk of permanent vision loss. Keep reading to learn more about treatment for this vision-threatening retinal condition. 

 

What is a Retinal Vein Occlusion? 

Any occlusion (blockage) of a retinal vein is called retinal vein occlusion. This can occur in the main vein of the retina, which is then known as a central retinal vein occlusion (CRVO), or in one of the smaller offshoot retinal veins, which is then termed a branch retinal vein occlusion (BRVO). There are also even smaller branches of the retinal vein network known as retinal capillaries. 

The retinal vein network is responsible for taking away deoxygenated blood from the retina back to the heart and lungs to be replenished with oxygen. Retinal arteries are the blood vessels that carry blood back from the lungs to the retina, restocked with vital oxygen and nutrients. 

 

Causes of Retinal Vein Occlusion

The causes of retinal vein occlusions tend to be due to a blood clot becoming trapped in the blood vessel. This blockage stops the flow of blood throughout the network of retinal blood vessels. 

 

Central Retinal Vein Occlusion

In a central retinal vein occlusion, the location of this blood clot is often around where the optic nerve enters the eye. In some cases, the clot can become lodged within the retinal vein after it’s exited the eyeball. 

 

risk factors prevention occlusion veins eyes melbourneBranch Retinal Vein Occlusion

During a branch retinal vein occlusion (BRVO), a clot is more likely to form at the point where the retinal vein crosses over a retinal artery.

Occlusion of branch retinal veins is up to seven times more frequent compared to blockages of the central retinal vein. 

 

Do Retinal Vein Occlusions Cause Vision Loss?

Vision loss from a retinal vein occlusion, whether in the central or branch vessel, is due to one or both of two possible complications. 

 

Macular Oedema

Macular oedema (also spelled as macular edema) refers to swelling of the macula area. The macula is the part of the retina you use for central vision. Damage to these nerve cells from macular oedema can result in significant vision loss. Because we use our central vision for so many crucial tasks, such as recognising faces, reading, and writing, vision impairment from macular oedema can be particularly devastating.  

 

Retinal Ischaemia

This is the medical term for lack of oxygen to the retinal nerve cells, which can affect a wide area of the retina or a small area, depending on the location of the retinal vein occlusion. 

If the retina is experiencing low oxygen, it often responds by growing new blood vessels. The problem is that these abnormal blood vessels can be subject to fluid leakage, which contributes to macular edema. The other complication is if these new blood vessels grow into the structures at the front of the eye, it can induce elevated eye pressure and subsequent damage to the optic nerve in a disease called neovascular glaucoma. 

 

 

Retinal Vein Occlusion Treatment

Timely treatment can help to maintain vision; however, despite treatment, it is possible to experience permanent damage and some degree of long-term vision loss. 

The decision on how best to treat a vein occlusion is based on the location and size of the blockage. Your eye doctor will perform a thorough assessment of your retina and any other relevant health problems. Tests can include imaging scans such as optical coherence tomography, which is useful for visualising the location and degree of macular swelling, and another test called fluorescein angiography, which shows a map of the retinal blood vessels, including areas of leaking fluid or retinal ischaemia. 

 

Intravitreal Injections

The first-line treatment for macular edema caused by a retinal vein occlusion is with a therapy called anti-VEGF injections. Anti-VEGF therapy involves intravitreal injection (that is, injected directly into the eyeball) of a drug known as anti-vascular endothelial growth factor, which inhibits the growth of abnormal new blood vessels. 

Anti-VEGF injections are also used to treat the swelling of the macula in macular edema. These injections will often need to be repeated monthly for at least a few months. If required, you may need further injections at regular intervals to maintain the effects of the therapy.

In some cases, laser treatment will be the most appropriate for treating the complications of a retinal vein occlusion. 

 

Focal Laser Therapy

Focal laser therapy involves the use of a laser tool to seal off blood vessels close to the macula to prevent fluid leaking. Essentially, the treated blood vessels are cauterised closed. 

 

Laser Surgery

Laser surgery can be used if new blood vessels are beginning to develop in the retina due to ischaemia. Using a laser to create tiny burns in the retina reduces its oxygen demand and minimises the trigger to grow extra vessels. 

 

Risk Factors and Prevention

Although it’s not possible to make yourself immune to ever experiencing a retinal vein occlusion, you can minimise your likelihood by understanding and managing your risk factors. 

The risk factors for retinal vein occlusion are similar to those for other cardiovascular diseases, such as heart attack and stroke. They include:

  • Older age
  • High blood pressure (hypertension)
  • High cholesterol
  • Diabetes
  • Being overweight
  • Smoking

Though you can’t do much about ageing, taking steps to control your other risk factors can help to reduce your risk of vision loss due to retinal vein occlusion. 

There is also some suggestion that the contraceptive pill can contribute to an elevated risk of retinal vein occlusion, though this has been rarely reported. Speak to your doctor if you have any concerns. 

 

 

Note: Any surgical or invasive procedure carries risks. Before proceeding, you should seek a second opinion from an appropriately qualified health practitioner.
