What Are The Factors That Lead To Retinal Vein Occlusion

What Are The Factors That Lead To Retinal Vein Occlusion?

Even though most people may not comprehend the complexity of an eye, numerous mile-second activities are involved in getting clear, focused eyesight. Our eyes are composed of many protective layers, tissues, and remote systems to see whenever we open our eyes. Retina or the front transparent part of the eyes reflects light and focuses the images we see. Problems or damages to the retina can lead to vision distortion and negatively affect our sight. Retinal vein occlusion is one such condition that occurs due to the blockage of blood supply in the vein that connects with the retina. The situation can cause blurriness and even lead to permanent blindness. This article will look into the factors that lead to retinal vein occlusion.

What Is Retinal Vein Occlusion (RVO)?

Our vascular systems transport blood throughout the body with the help of veins and arteries to every body organ, including the eyes. The light-sensitive tissue layer of our eyes, the retina, requires a constant blood supply to get adequate amounts of nutrients and oxygen. The process also involves removing waste that has been produced from the retina.

An occlusion or a stroke occurs due to blockage in an artery or a vein in our body. When this happens in the veins that supply blood to the retina, a retinal vein occlusion occurs. The occurrence can obstruct the retina from filtering retina and cause a sudden vision loss. The severity of sight loss can vary according to the location or the block, or the clot.

Factors That Lead To Retinal Vein Occlusion

Even though an exact reason for retinal vein occlusion has not been identified yet, the problem is due to narrow veins. Apart from this, several other medical conditions and habits can put you into the situation’s high-risk category. They are;

Atherosclerosis – A condition where fats and cholesterol buildups in artery walls that can restrict blood flow.

Blood clots travel – A blood clot that forms in an artery or a vein in a different part of your body can break loose and travel to the other part. This is called an embolus, and this can happen to your retina

Carotid artery disease – This is a major blood vessel in the neck that supplies blood to the brain, neck, and face. Blood reduction, narrowing, or blockage in these arteries can also result in retinal vein occlusion.

Macular edema – The condition causes fluid buildup, swelling, and thickening of the central part of the retina that can lead to retinal vein occlusion.

Diabetics – A significant long-term health condition that can lead to many problematic situations in the eye, including RVO.

High blood pressure – Elevated pressure can cause damages to the blood vessels and damage the retina.

High cholesterol – Significant amount of cholesterol deposits in arteries and veins can narrow them, causing blockage and clots.

Glaucoma – The second leading cause of blindness in the world that damages the optic nerve of the eyes.

Overweight – Obesity can increase the risk of many long-term medical conditions and eye issues that can eventually result in RVO.

Smoking, being over the age of 60, IV drug use, rare blood disorders are a few other situations that can lead to RVO condition. RVO usually occurs in one eye, and the permanent damages and vision loss can only be prevented by visiting the eye center immediately. Blurring vision, dark spots, pain, and pressure are a few symptoms you can experience directly.

Once you visit an eye center, eye drops will be used to enlarge your pupils, and an ophthalmoscope will be used to check bleeding or blockage in your retina. Fluorescein angiography and optical coherence tomography are a few other tests that your ophthalmologist will do to diagnose RVO. Injections, laser therapies, and surgeries will be recommended accordingly, depending on each condition.

If you have long-term medical conditions like diabetics, cholesterol, or pressure, it is essential to keep them in control and go for eye exams every six months to ensure your eyes are in a safe condition. Prevention before the occurrence is the ideal way to avoid situations like RVO that can even lead to permanent damages to the vision.

Discover 3 Types Of Cataracts How They Can Affect Your Vision Differently

Discover 3 Types Of Cataracts How They Can Affect Your Vision Differently

Vision can become compromised for many reasons. Cataracts are one of them. They are a common problem that affects people worldwide, and you might be at risk of getting it too. Understanding the condition is crucial to ensuring that you receive cataract treatment on time to retain your eyesight. Therefore, we will examine the three different types of this ailment and their differences in this blog.

What are cataracts?

Before exploring its types, it is essential to know what precisely a cataract is. It is a gray opaque cloudy area that covers the eye lens. If you have his condition, your vision can become blurry, like looking through a foggy window. In addition, it can affect your day-to-day life as you will have difficulty reading, driving cars, and observing facial expressions.

The condition develops slowly and, in the beginning, may appear as a grey dot in the eye. It does not immediately affect your vision; only doing so as it enlarges and becomes more prominent. There are three types of cataracts. While they share a set of core symptoms, there are differences in how they affect eyesight.

Nuclear sclerotic cataracts

It is the most common kind of cataract and begins at the nucleus of the eye, which is its center. It develops slowly and typically can take a few years to become prominent. The nucleus gradually hardens and becomes yellow, affecting other layers of the eye as the condition worsens. It has to be noted that there will be a very temporary improvement in close-up eyesight that could make you think you are becoming better. However, this is not the case, and your vision will quickly deteriorate.

Cortical Cataracts

Unlike nuclear sclerotic cataracts, it develops from the outer layers of the eye. It forms cortical spokes that start from outside the lens and make their way to the center as it progresses. This type causes blurred vision, glares and affects your depth perception and contrast. If you have diabetes, then you are more vulnerable to acquiring cortical cataracts.

Posterior subcapsular cataracts

It has the quickest development of all types of cataracts, typically taking a few months. It appears near the back of the lens as a small opaque spot, and as it develops, it interferes with light. As a result, you will find reading challenging. You will also find it difficult to see clearly when your surroundings are brightly lit. The cataract also impacts your night vision by creating glares and halos around lights. If you have significant nearsightedness or diabetes, you will be more likely to acquire this cataract type. The use of steroids can also increase risk.

How can they be treated?

In the beginning, specialists will recommend prescriptive glasses and stronger lighting to help you see more clearly. However, if the impairment grows, then the best treatment is cataract surgery. It is a standard procedure and is highly safe and effective. Suppose diabetes or other conditions are the reason for you developing cataracts. In that case, you will need to receive medication for that illness to stop any future resurgence. If you are suffering from cataract symptoms, it is vital to receive treatment immediately. Therefore, make sure to book an appointment at our Spanish clinic in Dubai for an examination.

Do’s & Dont’s Post Cataract Surgery

Dos & Don'ts Post Cataract Surgery

When your eye lens becomes cloudy and affects your eyesight, it is called a cataract, and your eye specialist will recommend undergoing cataract surgery in Dubai. It replaces your lens with an artificial one that will help restore your vision. Therefore, you will be able to enjoy a better quality of life, be safe and protect your eye health. While the surgical procedure is not complex, you will have to abide by specific rules afterward to ensure a smooth recovery. We will explore what they are in this article.

Do’s

Take the medication you are prescribed on time. After the surgery, your eye specialist will prescribe medicines that you need to take. While in the hospitals, our nurses would ensure you have them on time. Once you reach home, it is your duty, and you should make sure you have them as prescribed without any delay or alteration. Failing to take the medication could result in inflammation or irritation.

Do wear UV-protection sunglasses when going outside. After cataract surgery, your eyes are more sensitive than they used to be. Therefore, they could become vulnerable to UV exposure. To ensure they stay healthy, you need to wear sunglasses with a UV-protective coating when you go outside. The artificial lens does have a layer of the protective film; however, relying solely on that to keep your eyes safe could be unwise and risky. Typically, our doctor would recommend wearing the special sunglasses for at least a year to preserve your eye health.

Don’ts

Don’t rub your eye

After the procedure, your eyes will feel dry and itchy. Therefore, you may be tempted to scratch it. However, do not do so. If you rub your eye, you could move the new lens and displace it, causing blurry vision and problems with focus. If the lens moves to the vitreous cavity, it could result in vitreous hemorrhage or a retinal detachment. Repositioning a dislocated lens requires a more complex surgery with increased inflammation afterward. Therefore, always refrain from itching your eyes. If the discomfort is unbearable, speak to your doctor for new medication.

Do not wear eye makeup or any products that may contact your eye.

To properly heal after cataract surgery, even the best eye specialist will recommend avoiding wearing makeup after the procedure for at least one to two weeks. The reason we tell you this is to ensure you do not develop an infection. The eye makeup and products you use can harbor bacteria that could get into the eye and cause an infection. If the latter occurs, you may suffer from severe symptoms and could require urgent medical care. Your recovery period may also be affected significantly.

While cataract treatment can help restore your vision, failure to abide by the above rules could result in easily avoidable complications and expensive complex procedures. Therefore, speak to our eye specialist and discuss everything you should do and not do after the surgery. Afterward, make sure to abide by them for the best post-surgical recovery.

Ptosis: How Can You Spot The Symptoms Prevent It Earlier

Ptosis: How Can You Spot The Symptoms Prevent It Earlier

A relatively uncommon eye condition that does not get much attention in the UAE is Ptosis. It is impartial to people; therefore, anyone can get it. Knowing about the ailment and its symptoms is essential for you to obtain treatment early from an eye specialist in Dubai and save your vision. In this blog, we will explore this ailment and how it can be identified.

What is Ptosis?

It is a condition where your upper eyelid droops over the eye. It can affect both children and adults. The impact on your eyesight depends on the extent of the droop. There will be little effect; however, there can be a significant loss of vision if it covers the pupil. This is not only due to the eyelid blocking the view.

Once the brain realizes that the eyesight from an eye is compromised, it will start ignoring its signals. Thus, making the vision deteriorate and eventually leading to amblyopia. However, early detection and medical intervention can help the condition from worsening. Therefore, it is crucial to know the symptoms.

What are the symptoms?

The main symptoms of ptosis are as follows. If you believe you have any of them, you need to visit a Dubai vision eye center immediately.

Drooping Eyelids
The most recognizable and common symptom of this condition is the drooping of the upper eyelid. As the ailment mostly affects one eye, you will notice that one is more open than the other. Therefore, the eyelid of the affected eye will also be lower. If it only appears once in a while and the droop is slight, then the reason behind it could be fatigue and will resolve on its own. However, if it does not recede and remains prominent, then it is most likely ptosis.

Crossed Eyes
When you have ptosis, it is also expected to have crossed eyes, also known as strabismus. This is because the cranial nerve is responsible for eye alignment and eyelid movement. As the eye muscles are all closely related, it is likely that the eyeball will also be affected when an issue affects an eyelid. However, this is not always guaranteed.

Double Vision
If you have strabismus as a symptom, you will likely have double vision. Because the eyes are not aligned, they cannot focus on the same thing and send different signals to the brain. Consequently, you will see two images instead of one.

Tilting Head Backward
If the ptosis is severe and is blocking the pupil, you will have to move your head to the back to see clearly. Over time, this can lead to neck and head problems such as soreness and pain.

Difficulty Closing The Eye
Suppose the condition is caused by a neurological disorder that affects eye muscles or nerves. In that case, you might find it difficult to close the eye or blink. It is because the nerves and muscles will not be able to work together.

Dry & Irritated Eyes
As the eyelids protect the eyes from dirt and ensure the eyeball stays moist, you will have dryness if it cannot close correctly. Therefore, your eyes will become red and irritated.

By taking action as soon as you notice symptoms, you can stop ptosis from becoming worse and save your eyesight. Therefore, if you think you might have the condition, contact us and make an appointment to see the best eye specialist in Dubai.

IntraLase Treatment Delving Deeper Into The Process Of This Surgical Procedure

IntraLase Treatment Delving Deeper Into The Process Of This Surgical Procedure

Human beings perceive up to 80% of all sensory information in their environment through their eyes. Therefore, good eyesight is essential for a person to do their day-to-day activities without facing any inconvenience. For example, if your vision is compromised, you might find simple tasks such as grocery shopping incredibly challenging. Therefore, visiting an eye specialist in Dubai  is crucial to saving your sight.

For many decades, people believed that the only way to correct poor vision was through corrective lenses; however,  LASIK eye surgery in Dubai has changed that view. They made it possible for a person to see clearly without needing any additional equipment. While there are many types of this procedure, one of the more popular ones is IntraLase, and we will explore it in this blog.

What is IntraLase surgery?

It is a type of LASIK surgery developed by Johnson & Johnson to enhance the primary LASIK procedure. It is a bladeless operation and is used to correct refractive errors such as myopia, hyperopia, presbyopia, and astigmatism.

It is highly advanced and accurate, using femtosecond (quadrillionth of a second) laser pulses to form the flap necessary for LASIK. It is considered one of the best LASIK surgeries as it has a tremendous success rate and is very safe.

What is the process?

Unlike traditional LASIK, which uses a microkeratome blade to cut the cornea and create a flap, IntraLase doesn’t touch the outer cornea layer at all. Instead, it uses an ‘inside-out’ process using infrared light to create the flap from below the cornea’s surface. As a result, the beam passes safely through the outer corneal layers without causing any harm. We will examine the process in detail below.

Step 1

The eye specialist will decide on the flap’s dimensions based on your eyes and use computer-controlled laser beams to create the flap with absolute precision. They will focus on a specific spot in the stroma and use tiny pulses of infrared light, roughly a quadrillionth of a second in duration, to create a uniform layer of microscopic bubbles under the cornea surface.

Step 2

Thousands of these bubbles are positioned carefully so the surgeon can define the flap’s dimensions, beveled edge, and hinge location. Afterward, the bubbles are stacked along the flap edge to the corneal surface to complete the flap. The process is very swift and can be finished in 45 seconds.

Step 3

Once the flap is created, the surgeon will lift it to apply the LASIK procedure to shape your cornea. Once the treatment is complete, the flap will be repositioned accurately due to its beveled edge. Your eye will then begin healing rapidly.

Most patients favor IntraLase surgery because the recovery process is much quicker. There are also significantly fewer side effects than other types of LASIK procedures. In addition, night glare and halos do not occur due to the precision of the surgery and reduced aberrations. Enhancement operations after the primary procedure are also rarely required. If you wish to do this surgery, make sure to contact the best eye specialist in Dubai to find out more about it.

Corneal Scarring Understanding The Primary Causes Symptoms Of This Condition

Corneal Scarring Understanding The Primary Causes Symptoms Of This Condition

Broken bones, also known as bone fractures, are a leading cause of why people seek medical help in orthopedic clinics in Dubai. Depending on its severity, you may even need urgent attention from the accident and emergency unit. They can occur for various reasons and typically require medication and treatment to ensure your bone can heal correctly. We will examine this condition in-depth in this article.

What are bone fractures?

It is a medical condition where there is a break or a crack in your bone. While bones are strong, they can break if the force exerted on the bone is greater than it can withstand or are constantly exposed to continuous pressure. Therefore, weakening and causing them to break and change their shape. The fracture could be complete or partial and can occur in numerous ways: lengthwise, crosswise, or separate into several smaller pieces. The most vulnerable sites for fractures are the wrist, hip, and ankle.

What are the causes?

As mentioned above, fractures can occur when your bone comes into contact with a strong force, for example, meeting with a car crash, falling on hard ground, or being impacted by falling objects. They can also occur if you are exposed to a repetitive force that can gradually affect your bones and cause a break, such as running long distances or repeatedly jumping up and down. The latter is called stress fractures and typically occur in athletes or older adults.

Another cause is medical conditions that can weaken bones. Some of the most prominent ones are osteoporosis, rheumatoid arthritis, or brittle bone disease. When medical conditions cause fractures, bone specialists call them pathological fractures.

What are the symptoms?

The symptoms of fractures depend on which bone is affected, the severity of the injury, and a patient’s age and health. However, typically, you would have one or more of the following.

  • Pain
  • Bruising
  • Swelling
  • Angulation – the area that is affected, could be bent at an abnormal angle
  • Discolored skin near the area that is affected
  • A grating sensation on the affected joint or bone
  • You could have difficulty applying weight to the area
  • Difficulty moving the affected area
  • Bleeding


If a large bone is affected, you may have more severe symptoms such as:

  • You will appear more pale and sweaty
  • You could have nausea
  • You may feel dizzy

What is the treatment?

When you notice symptoms of a fracture, depending on its location, you should not move until a healthcare professional is present. If you are in a dangerous place, you can relocate to safer ground, but do not apply pressure or move the affected areas. If your symptoms are manageable and you can walk, you can visit the accident and emergency unit.

You will be given one or more tests to diagnose the fracture and determine its severity, such as x-rays, bone scans, CT scans, or MRI. Then, depending on the results, your doctor may give you a cast or a splint, which immobilizes the bone and straightens it so it can heal. You may also be given traction to stretch the muscles and tendons around the affected bone and align it.

If the fracture is severe, you will have to undergo orthopedic surgery, which involves using screws, plates, or frames to steady the bone and allow it to heal.

If you suspect a fracture, you need to consult our medical clinic. We will examine the break and provide you the necessary treatment or direct you to our orthopedic surgeon in Dubai for surgery.

Minimally Invasive Glaucoma Surgery The New Approach To Glaucoma Treatment

Minimally Invasive Glaucoma Surgery The New Approach To Glaucoma Treatment

Glaucoma is a common yet highly impactful eye condition. It can cause widespread effects in your day-to-day life, with activities such as driving and playing sports becoming more challenging. However, a new and innovative glaucoma treatment Dubai aims to improve your symptoms and restore your vision: minimally invasive glaucoma surgery. We will explore this procedure and its effects on your eye health in this article.

What is glaucoma?

An eye condition develops when the optic nerve, which connects the retina to the brain’s visual cortex, becomes damaged. A fluid build-up primarily causes it in the front of the eye that increases pressure within the eye. Although it can affect people at any point in their lives, those above 70 are more vulnerable. If left undiagnosed or untreated, glaucoma can gradually lead to a loss of vision. Therefore, identifying symptoms is crucial but could be difficult.

Many patients do not suspect they have the condition until it is picked up in a routine eye test. However, if you pay attention, you could pick up some of the signs. There are two main types of glaucoma, and the symptoms can vary between them.

Open-angle glaucoma

  • Blind spots may be present in your central or peripheral vision of both eyes.
  • Tunnel vision if the condition is in an advanced stage.


Acute angle-closure glaucoma

  • Eye pain
  • Blurred vision
  • Severe headache
  • Nausea and vomiting
  • Eye redness
  • Halos around lights

What is minimally invasive glaucoma surgery?

Also known as MIGS, it is a procedure carried out by glaucoma specialists to lower eye pressure and prevent or reduce optic nerve damage. The group of operations that belong to this category has been developed in recent years to reduce the complications of traditional glaucoma surgeries.

The traditional glaucoma surgeries—trabeculectomy and tube shunt procedures— are major surgeries with many possible complications, though they are highly effective. These include double vision, eye infections, cornea swelling, choroidal detachment, retinal detachment, and vision loss.

On the other hand, MIGS surgeries reduce the prevalence of complications and are safer than standard procedures. The treatment typically uses microscopic-sized equipment and small incisions to correct the condition; they are minimally invasive and quicker healing.

They are divided into the following categories:

  • Miniaturized versions of trabeculectom
  • Internal or suprachoroidal shunt
  • Trabecular bypass operation
  • Milder, gentler versions of laser photocoagulation


Depending on your type of glaucoma, its effects, and your age and overall health, our glaucoma specialist will recommend a suitable MIGS procedure for you.

How effective is MIGS?

MIGS procedures have allowed us to lower the threshold for surgical intervention. Therefore, we can control your intraocular pressure better and preserve your vision at early stages without solely relying on heavy medication. However, the procedure is not yet consistent in its effectiveness. While some types only reduce the pressure by a small amount, others can have more significant reductions but require a longer healing time to recover eyesight.

At present, MIGS surgeries will not eliminate or replace the need for traditional glaucoma surgical procedures. However, they have significantly decreased the number of patients who require these procedures to control their intraocular pressure.

If you notice symptoms related to glaucoma, make sure to contact our eye clinic in Dubai and consult a specialist. They will give you the essential information and treatment to preserve your vision.
