What is a Scotoma in the Eye?

Vision is one of the most important senses we have. Any problem with it can change the way we see the world. For example, imagine you are reading a book, and suddenly, a blank spot appears where the text should be. You try to see the words, but they stay hidden. This is a sign of an issue called scotoma, which refers to abnormal blind spots in your vision.

Although this may seem worrying, do not panic. With early detection and the right treatment, you can manage scotoma. Taking action early can help prevent more serious problems and keep your vision healthy.

If you want to learn more about scotoma, including its causes, symptoms, and treatments, keep reading this blog for all the details.

What is Scotoma?

Scotoma is a Greek word that means darkness. It is a medical term used for blind spots. Every human being has a pin-sized blind spot in the eyes, but it goes unnoticed because the brain automatically fills in the missing information. But in cases when your optic nerves don’t work and can’t send signals to the brain, there comes an abnormality in your vision known as scotoma.

Scotoma looks like a dark, blurry spot or an arc of light. It can happen in one or both eyes and is of varying size and shape. Whether it’s temporary or permanent, a scotoma can impact daily life activities like driving, reading, recognizing faces in the crowd, and many others.

Types of Scotomas of the Eyes

Now, let’s discuss some of the different types of scotoma:

1. Central Scotoma

A blind spot directly in the center of your vision is referred to as central scotoma. In this type, you will see a dark spot, smudge or blurred vision in the center of your eyes.

2. Scintillating Scotoma

Scintillating means sparkling or shimmering. Such scotoma is a sparkling visual disturbance mainly associated with migraines and moves across your field of vision.

3. Paracentral Scotoma

This scotoma occurs near the central vision but does not directly impact it. For instance, if you look at a road sign, you can read the words clearly, but you can not see objects that are slightly off-center.

4. Junctional Scotoma

It is a complex type of scotoma that happens at the junction of the optic nerve and optic chiasm. The optic chiasm is the point where the optic nerve enters the brain. This affects your vision in a specific area of the visual field.

Causes of Scotoma

There are different conditions that affect the optic nerve and can result in scotoma. Below, we have compiled the most common of these causes:

Symptoms of Scotoma

Though the symptoms of scotoma depend on its type and severity, the most common ones are:

• Difficulty is seeing different colors
• Vision loss
• Difficulty in seeing fine details
• A sensation of blind spots when looking at different objects.
• Headaches or migraines
• Floaters or dots

Scotoma Diagnosis Procedure

Now that you are aware of all the causes and symptoms of scotoma, let’s see how your eye care specialist will assess your condition. After getting all your medical history, they usually perform the following key steps:

1. Routine Eye Exam

Routine eye examination is painless and performed to test your vision and eye health.

2. Visual Field Testing

This is a crucial step in which you are asked to look at fixed points in order to identify the blind spots. It maps out your areas of vision loss.

3. Optical Coherence Tomography (OCT)

This test provides cross-sectional images of the retina to identify the abnormalities.

4. Fluorescein Angiography

This step is also very important to visualize blood flow in the retina and reveal any underlying issues.

Based on these results, your doctor will suggest suitable treatment options.

How to Treat Scotoma of the Eye?

Let’s discuss here some of the common treatment methods:

• Eyeglasses or Contact Lenses

If the scotoma is caused by refractive errors, prescribed eye glasses or contact lenses will help you a lot.

• Medication

Your doctor would prescribe certain anti-inflammatory drugs and anti-oxidants to deal with different optical conditions.

• Lasik Therapy

LASIK is also suggested to reduce the risk of vision loss.

• Surgery

If scotoma is caused by eye injury or tumors, surgical vision correction is the best way to deal with it.

• Lifestyle Adjustments

In addition to the particular treatments, your doctor would suggest lifestyle changes to support your overall eye health. These include a diet rich in antioxidants and vitamins and regular eye exams.
