Retinal Disorders Introducing The Common Problems And Their Symptoms

Retinal Disorders Introducing The Common Problems And Their Symptoms

The retina covers the inside of the back two-thirds of the eyeball and is a sensory membrane that receives light and converts them into neural-signals for visual recognition. It plays a significant role in vision, and the damages can cause a mild to severe range of problems which include permanent blindness conditions. The ophthalmologist emphasizes the importance of visiting the eye clinic for early treatments to prevent possible permanent damages to the eyes. Hence, this article will look into the most common retinal disorders and their symptoms for your understanding.

Retinal Detachment

The condition is an immediate situation where a thin layer of tissues situated at the back of the eye pulls away. The change in position separates the blood vessels from the retinal cells. These vessels are involved with continuous blood to the retina supplying oxygen and nutrients. A detachment of retinal cells can risk a permanent vision loss if left untreated. The symptoms of retinal detachment include;

  • The sudden appearance of floaters and flashes
  • Reduced or blood vision
  • Reduction in peripheral or side vision
  • A shadow over the visual field.

Retinal Tear

When the thin transparent front part of your eye or the retina gets damaged, and a crack develops, a tear is formed. The occurrence can be spontaneously and considered as the most common retinal issue among populations. Injuries, trauma, eye surgeries are a few causes for the event of a retinal hole. The symptoms of the condition include;

  • Sudden onset of floaters and flashes of light
  • Hazy vision
  • A dark spot in the visual field

Macular Hole

The macula is located in the center of the retina and is responsible for providing a sharp central vision required for reading and driving. A macular hole is a small break in the macula that can cause blurred and distorted vision. The condition can be mostly seen with aging and among people over the age of 60. The most common signs are;

  • Distortion or blurriness in central vision
  • Seeing straight lights in a wavy form
  • Difficulty in reading and driving

Age-Related Macular Degeneration

Just like the name interprets, the condition is linked with aging, where the eyesight of a person can worsen over time and even lead to permanent vision loss. This happens when the macula wears down and can be mostly seen in people over 60. The condition is categorized into two types, dry form and wet form, where the dry form can cause yellow deposits in the macula. In the wet form, the growth of blood vessels underneath the macula can be observed. The common symptoms include;

  • Blurry and worsen eyesight.
  • Dark and blurry areas in the central vision
  • Different color perceptions (a rare symptom)

Diabetic Retinopathy

Diabetes is a common long-term medical condition that affects the way your body turns food into energy. This chronic condition can cause problems in your eyes, including diabetic retinopathy, leading to vision loss and blindness in people. It is essential to visit an eye hospital regularly for people with diabetic conditions for early prevention. Although symptoms cannot be seen initially, changes can be seen in the later stages. They are;

  • Dark floating spots or streaks
  • Patchy vision
  • Eye pain or redness
  • Sudden vision loss


If you experience any of these situations and observe any unusualness in your sight, visit our eye specialist immediately for a comprehensive examination.

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.
