Conjunctival Nevus
Conjunctival nevus: careful checks of spots and pigment changes on the white of the eye
About
What Is a Conjunctival Nevus?
When melanocytes become active, pigmentation like the moles that appear on the skin or face
can develop on the white of the eye (the conjunctiva).
A brown spot appearing on the white of the eye is called a conjunctival nevus.

Causes of Glaucoma
-
Congenital factors
In some cases, nevus cells are present from birth.
Although they exist from birth, the pigment can become active during adolescence or adulthood, making the spot darker or more noticeable. -
Chronic external irritation
Exposure to strong UV rays from sunlight continuously stimulates melanocytes, and chronic eye irritation from wind, dust or dry eye syndrome
can also promote the formation and growth of a nevus. -
Acquired development
Small injuries from a habit of frequently rubbing the eyes can stimulate melanocytes
and cause a spot to form later in life.
Spots may also develop naturally with age.
Types of Conjunctival Nevus
Most conjunctival nevi (spots on the white of the eye) are benign and harmless, but in rare cases they can develop into malignant melanoma.
A sudden change in a nevus is a strong warning sign that the reason the spot is growing may be more than a simple mole.
Be sure to check for the following 4 key signs and visit an eye clinic.
-
1
Color changeThe nevus suddenly turns a deep black, or several shades such as brown, black and blue
appear irregularly mixed within a single
spot. -
2
Increase in size/thicknessThe nevus grows noticeably and rapidly (why spots on the eye get bigger), or it bulges out more than before with a thickness you can almost feel (nodule formation).
-
3
Irregular borderThe edge of the nevus is no longer smooth and becomes uneven
or jagged. A blurred border spreading into the surrounding conjunctiva is also a warning sign. -
4
New blood vessel formationNew red blood vessels that were not there before appear around the nevus, or the nevus itself becomes inflamed or bleeds.
Conjunctival Nevus Treatment and Removal
Most conjunctival nevi are benign, but removal may be considered for cosmetic improvement or to manage the risk of malignant change.
At BSM Eye Clinic, we recommend the most suitable and safest treatment based on the depth, size and type of the nevus.
-
1 Laser Removal
A special ophthalmic laser is used to break down the melanin
pigment in the nevus and finely cauterize and remove the surface epithelium
where the nevus is located.-
Advantages
- No incision needed, so less pain
- Short procedure time
- Fast recovery
-
Suitable for
- Shallow, superficial conjunctival nevi
- Relatively small nevi
-
-
2 Chemical Peeling
Safe chemical agents such as alcohol are used
to gently remove the surface epithelium where the nevus is located.-
Advantages
- Relatively simple procedure
- Can be used even when the pigment is widely spread
-
Suitable for
- Shallow, superficial conjunctival nevi
- Some cases where laser treatment is not suitable
-
-
3 Surgical Treatment (Safe and Complete Removal)
When nevus cells lie deep or malignant change is suspected,
surgical removal is needed to minimize the chance of recurrence
and allow an accurate diagnosis.-
Advantages
- Low recurrence rate
- The removed tissue can be examined to accurately determine whether it is malignant (diagnostic value)
-
Suitable for
- Deep compound nevi
- Recurrent nevi
- Very large nevi
- Lesions suspected of malignant change
-

Conjunctival Nevus Removal Q&A
We’ve gathered the key questions patients ask most often
before starting treatment at BSM Eye Clinic.
Q.
Are there cases where conjunctival nevus removal is necessary beyond cosmetic reasons?
A.
Yes. Most conjunctival nevi are benign, but in rare cases they can undergo malignant change.
If warning signs such as a growing spot, discoloration of a spot on the white of the eye or an irregular border are found,
removal should be seriously considered after a conjunctival nevus diagnosis.
Beyond cosmetic reasons, managing the risk of malignant change is an important purpose of removing spots on the white of the eye.
Q.
What are the treatment options for conjunctival nevus removal (laser or surgery), and what is the chance of recurrence?
A.
The removal method depends on the depth of the nevus.
Laser treatment is used for shallow nevi, while surgery is used for deep nevi or those suspected of being malignant.
Whichever method is chosen, there is always a chance of recurrence, so skilled technique and thorough follow-up after removal are important to minimize it.
Q.
Does a conjunctival nevus need to be removed before LASEK/LASIK surgery?
A.
In general, a conjunctival nevus is located on the white of the eye (the conjunctiva), not on the cornea where LASIK or LASEK is performed, so it does not directly affect vision correction itself.
However, if the nevus is very large or may obstruct the surgical field, removal of the spot may be recommended before surgery following a conjunctival nevus diagnosis.
