Seeing Black Spots In Vision: Causes Besides Floaters

Sudden black spots in vision that are not eye floaters can be concerning for individuals experiencing them. These visual disturbances can be caused by various factors, ranging from age-related macular degeneration to more temporary conditions such as scintillating scotomas or even retinal issues that require medical attention, such as retinal tears or detachments.

Understanding the possible causes for these black spots is crucial for determining whether they require urgent attention or can be managed through lifestyle adjustments and medical treatments. It is important to always seek professional advice especially when you have new floaters or a sudden increase in floaters. Only an eye specialist will be able to look in the back of the eye to determine what is causing your symptoms. If it is the weekend or evening, you may need to head to the emergency room to ensure that there is no retinal damage or other serious condition.

Causes of Sudden Black Spots in Vision

There are several reasons why an individual might experience sudden black spots in their vision. It is important to note that diseases below can also have other presenting signs and symptoms and black spots in the field of vision may or may not be necessarily part of it. In general, patients should seek immediate attention for any new dark areas of vision or a new blind spot in their vision.

Detached Retina

Retinal detachment is a serious eye condition in which the retina separates from the underlying layer of supportive tissue. This can cause sudden black spots in one’s vision and may be accompanied by other symptoms such as flashing lights or a loss of peripheral vision. If left untreated, a detached retina can lead to permanent vision loss. If you experience a shower of floaters or a curtain coming over the vision you should seek emergent medical advice from an ophthalmologist (ideally a retina specialist).

Retinal Hemorrhage

A retinal hemorrhage occurs when a retinal blood vessel leaks or become damaged. This can result in the sudden appearance of black spots in one’s vision or reduced visual clarity. Underlying causes of retinal hemorrhage include diabetes, high blood pressure, or injury to the eye.

Macular Hole

A macular hole is a small break in the macula, the central region of the retina responsible for our central vision. This can lead to a central scotoma. A scotoma can look like a black or gray spot. A black spot in the affected eye, along with blurred vision or distorted vision. The risk of developing a macular hole increases with age, and it may be associated with certain eye conditions or injuries.

Ocular Migraine

Ocular migraines are a type of headache that can cause visual disturbances, temporary scotomas, including sudden black spots or blind spots in one’s vision. These may be temporary and last from a few minutes to an hour. Ocular migraines typically affect one eye at a time and can be accompanied by other migraine symptoms such as nausea, sensitivity to light, or a throbbing headache. In addition to possibly seeing small specks or small spots, patients may also see a kaleidoscope of colors or squiggly lines. The dilated eye exam in these patients is usually normal.


A stroke can restrict blood flow to the brain, which may lead to sudden black spots in one’s vision, double vision, or vision loss. Strokes are a medical emergency and require immediate treatment to minimize the risk of permanent damage or disability. They may be more common in old age and in patients who have high blood pressure.

Other Ocular Conditions

Other vision problems can cause sudden black spots in one’s vision, such as age-related macular degeneration (AMD) and inflammation of the eye. In addition, trauma to the eye or other underlying health conditions may result in visual disturbances. It is essential to consult a healthcare professional if experiencing sudden black spots in vision to determine the cause and receive appropriate treatment.

Symptoms And Indicators

Differentiating from Floaters

Sudden black spots in vision, which are not floaters, can be alarming and confusing. It is important to differentiate them from floaters to understand their potential cause and seek appropriate treatment. While floaters appear as small, moving specks, sudden black spots remain fixed and may be darker in appearance.

Floaters, typically seen as threadlike or cobweb-like lines, usually move alongside the eye’s movement, while sudden black spots may have a more stationary quality. In some cases, these fixed spots may flicker or waver between dark and light, indicating a scintillating scotoma.

Associated Symptoms

There are several symptoms that may accompany sudden black spots in vision. These include flashes of light, wavy or distorted lines in the visual field, temporal loss of clear vision, peripheral vision loss and darkness on the side of the visual field. These symptoms can be associated with different underlying conditions such as a retinal tear, inflammation, or age-related macular degeneration. It is essential to consult an eye care professional if you experience sudden black spots in vision accompanied by any of these symptoms to receive proper diagnosis and treatment.

Diagnosis And Tests

Sudden black spots in vision, which are not floaters, can be concerning and may indicate a serious eye issue. To diagnose the underlying cause, a series of tests and examinations are performed.

Eye Examination

A comprehensive eye examination is crucial for detecting any abnormalities that may cause black spots in vision. A healthcare professional will typically assess the patient’s visual acuity, visual field, and ocular health. This can include slit-lamp examination, tonometry to measure intraocular pressure, and a dilated fundus examination to evaluate the retina and other internal structures of the eye(source).

Imaging Techniques

Imaging techniques such as optical coherence tomography (OCT) and fluorescein angiography can provide detailed information about the retina and choroid, assisting in the identification of any issues causing the black spots in vision. OCT uses light waves to create high-resolution cross-sectional images of the retina, while fluorescein angiography involves injecting a dye into the patient’s bloodstream and taking photographs of the blood vessels in the retina.

Referral To Ophthalmologist

If the initial eye examinations and imaging techniques point toward a specific underlying issue causing the sudden black spots in vision, such as a retinal tear, detachment, or eye melanoma, the patient may be referred to a specialist for further evaluation and treatment.

Treatment Options

Sudden black spots in vision not floaters can be a cause for concern, and having a clear understanding of the various treatment options helps in addressing the issue effectively.

Surgical Procedures

Depending on the underlying cause of the sudden black spots, surgical procedures might be recommended by your eye doctor. In case of retinal tears or detachments, laser therapy or surgery may be needed.


In some cases, medications might help reduce the black spots in vision. For instance, if the cause of the black spots is related to severe eye inflammation, anti-inflammatory drugs or steroids may be prescribed to alleviate the symptoms. It’s important to consult with your eye doctor to determine if medications are suitable for your specific condition.

Lifestyle Changes

Lifestyle changes will usually have little to no impact on many of the medical conditions mentioned above. The only significant risk that someone may be able to modify is if they are in an occupation where trauma to their eye is highly likely. For example, if someone is an avid boxer, they are more at risk for a retinal tear due to trauma. Remember that it is crucial to consult with your eye doctor if you notice sudden black spots in your vision, as proper diagnosis and prompt treatment play an essential role in maintaining good vision and eye health.

Prevention And Management

Regular Eye Checkups

One of the most effective ways to prevent and manage sudden black spots in vision is by scheduling regular eye checkups with an eye care professional. This can help detect any underlying conditions, such as retinal detachment or central serous chorioretinopathy, before they become severe and lead to vision loss.

Protective Measures

Taking protective measures can help reduce the risk of sudden black spots in vision by using protective eyewear during sports or other activities with a risk of eye injury. Be mindful of your surroundings and avoiding situations with potential eye hazards.

Risk Factor Reduction

Reducing risk factors associated with sudden black spots in vision can also help prevent and manage the problem. Properly manage chronic health conditions, such as diabetes, to prevent complications like diabetic retinopathy which can cause eye bleeds and retinal detachments. Maintain a healthy blood pressure, as high blood pressure can harm blood vessels in the eye.

Black Spots In Vision That Are Not Floaters: Summary

Sudden black spots in vision not associated with floaters can be a cause for concern, often indicating an underlying issue that warrants medical attention. For many patients have a number of floaters is common because the vitreous liquefies with time naturally. The vitreous gel is a jelly-like substance that helps the eye to maintain its shape. Vitreous floaters are natural as you age because the vitreous fluid breaks up with time and can cause the appearance of tiny black spots.

In some cases, black spots in the vision can be the sign of a more serious problem. It is important to see an eye care specialist to make sure that you do not have a torn retina or a higher risk eye disease. Early detection and treatment of such conditions can significantly reduce the risk of vision loss.

In conclusion, while some black spots in vision may be harmless, it is important to pay attention to any sudden or unusual changes in one’s sight. Consulting with an eye care professional when faced with non-floater related dark spots can help prevent complications and ensure the maintenance of optimal ocular health.
