Flat Nevi Around the Eye: Risks and Treatment Options - Ophthalmology

More Info

---

Flat nevi, or flat moles, around the eye can be a source of concern for many individuals, especially when there are changes in size, color, or shape. In your case, you have a flat nevus larger than 0.1 cm around your left eye's pupil and three smaller black spots. You mentioned having undergone laser surgery six years ago, which raises questions about whether the changes you are observing could be related to that procedure or perhaps due to previous trauma.

First, it is essential to understand that flat nevi are generally benign and are common among individuals of various ethnic backgrounds, including those of East Asian descent. However, any changes in the appearance of a nevus, such as an increase in size, changes in color, or irregular borders, should be evaluated by a qualified ophthalmologist or dermatologist. The concern about the potential for a nevus to develop into melanoma, a type of skin cancer, is valid. While the risk is relatively low for flat nevi, it is crucial to monitor them closely.

The fact that you have noticed the nevus around your pupil growing larger is particularly important. Changes in size can be a warning sign, and it is advisable to seek a thorough examination from an eye specialist who can assess the nevus using specialized equipment, such as a slit lamp or dermatoscope. These tools allow for a detailed examination of the nevus and can help determine whether any further action is necessary.

Regarding your concern about the need for surgical intervention, it is important to note that not all procedures require the removal of the entire eye. If a nevus is suspected to be malignant or if it is causing visual disturbances, a biopsy may be performed. This can often be done with minimal impact on the surrounding tissues. In some cases, only the nevus itself may be excised, preserving the integrity of the eye. However, if the nevus is located in a sensitive area or if there are signs of malignancy, more extensive surgery may be necessary, but this is typically a last resort.

You mentioned that an eye doctor previously reassured you that the nevus is not a cause for concern due to your ethnicity. While it is true that certain populations may have a lower incidence of ocular melanoma, it is essential to remember that individual risk factors can vary. Therefore, it is prudent to remain vigilant and proactive about monitoring any changes in your eye health.

In summary, here are some steps you should consider taking:
1. Regular Monitoring: Keep an eye on the nevus and any changes in size, color, or shape. Document these changes if possible.

2. Seek Professional Evaluation: Schedule an appointment with an ophthalmologist who specializes in ocular tumors or a dermatologist with experience in skin lesions around the eyes. They can provide a comprehensive evaluation and determine if a biopsy is necessary.

3. Discuss Treatment Options: If the nevus is found to be benign but concerning, your doctor may recommend regular follow-ups. If it is determined to be malignant, they will discuss the appropriate treatment options, which may include surgical excision.

4. Educate Yourself: Understanding the signs of melanoma and other skin cancers can empower you to seek help promptly. Look for changes such as asymmetry, irregular borders, multiple colors, and an increase in size.

5. Avoid Self-Diagnosis: While it is helpful to research your condition, avoid relying solely on internet sources for diagnosis or treatment advice. Always consult with a healthcare professional for accurate information.

In conclusion, while flat nevi are often benign, any changes warrant a thorough examination. Early detection and intervention are key to managing potential risks effectively. Stay proactive about your eye health, and do not hesitate to seek a second opinion if you feel uncertain about the advice you have received.
