Black Spots on the Eye: Causes, Risks, and Treatment Options

Q: Black Spots on the Eye: Causes, Risks, and Treatment Options

Hello, Ah Xiang： 1. Is it possible that repeatedly picking at the white part of the eye with your fingers could cause irritation and result in a black spot or "mole"? It is possible, but maybe not. However, this is not important; the outcome is the same. 2. <b

Follow-up question #151742: Black spots on the sclera?

Dear Dr.
Gao,
Thank you very much for your response regarding the article "#151742 Eye White Black Spot." I would like to ask the following questions:
1.
In your response, you mentioned that the black spot on the white part of my right eye may not be a result of bruising but rather a "nevus." The reason I am asking is that, in the past, while removing my contact lenses, my fingernail repeatedly scratched that area of the eye, and I noticed a black spot forming at that time.
I initially thought it was just a bruise that would be absorbed by my body, but it has persisted until now.
Therefore, I would like to ask if the black spot on the white part of my right eye could be a result of repeated scratching by my fingernail, causing irritation that led to the formation of a black spot or "nevus"?
2.
Following up on that, if the black spot on the white part of my right eye is indeed a "nevus," what potential effects or pathological changes could arise from it (such as melanoma)? Additionally, how can one determine whether there is any pathological change?
3.
You mentioned that the only current method to remove the black spot on the white part of the eye is through "surgical removal." I would like to ask if laser treatment for myopia could be applied to remove the black spot on the white part of the eye? In other words, is there a method to use "laser" to remove the black spot on the white part of the eye?
Thank you, Dr.
Gao.

2.
As long as there are no changes, it is usually benign.
If there is growth or significant change, further examination is necessary.

3.
Myopia laser surgery cannot remove black spots on the white part of the eye; a different type of laser is required.

More Info

Understanding black spots on the eye, particularly on the sclera (the white part of the eye), can be a source of concern for many individuals. The presence of these spots can arise from various causes, and understanding their implications is crucial for maintaining eye health.

1. Causes of Black Spots: The black spots you are observing on your sclera could indeed be a result of trauma, such as the repeated irritation from your fingernail when removing contact lenses. This type of trauma can lead to localized bleeding or pigment changes, which may appear as dark spots. However, it is also possible that these spots are nevi (moles) or other benign pigmented lesions. Nevi are generally harmless but can sometimes change over time, which warrants monitoring.

2. Potential Risks and Changes: If the black spot is a nevus, it is typically benign. However, any changes in size, shape, or color should be evaluated by an eye care professional. In rare cases, pigmented lesions can develop into more serious conditions, such as melanoma, which is a type of cancer that can affect the eye. Regular eye examinations are essential for monitoring these changes. An ophthalmologist can perform a thorough examination, including imaging techniques like optical coherence tomography (OCT), to assess the lesion's characteristics and determine if further action is needed.

3. Treatment Options: As you mentioned, surgical removal is often the only definitive way to eliminate a pigmented lesion on the sclera. While laser treatments are widely used for various eye conditions, they are not typically employed for removing pigmented lesions on the sclera due to the risk of complications and the need for precise tissue handling. Surgical excision remains the gold standard for ensuring complete removal and for histopathological examination to rule out malignancy.

4. Monitoring and Follow-Up: It is crucial to keep an eye on any changes in the appearance of the black spot. If you notice any new symptoms, such as changes in vision, increased irritation, or discomfort, you should seek immediate medical attention. Regular check-ups with an ophthalmologist can help ensure that any potential issues are caught early.

In summary, while black spots on the sclera can be benign, it is essential to monitor them closely and consult with an eye care professional for a comprehensive evaluation. They can provide guidance on the best course of action, whether that be monitoring, further testing, or surgical intervention if necessary. Maintaining eye health through regular check-ups is key to preventing potential complications and ensuring your vision remains clear and healthy.

If it really increases, you must be cautious and undergo a dilated eye exam to confirm there are no retinal tears. If it is confirmed that there are no tears, regular check-ups are still recommended. Floaters typically do not go away, and you may need to adapt to them!
