Description
A conjunctival nevus, also known as an eye freckle or mole-like spot, is a benign growth that occurs on the clear film (conjunctiva) covering the eyeball. It is a very common type of lesion and can be present at birth or develop over time.
Characteristics:
- A conjunctival nevus is typically a discrete lesion on the conjunctiva.
- It can range in color from dark brown to yellow.
- Many times, it will contain clear cystic spaces within the lesion.
- The size of the lesion can vary, but it is usually small.
Types:
- There are several types of nevi, including junctional, compound, and subepithelial nevi.
- Conjunctival melanocytic tumors comprise benign and malignant neoplasms, with nevi being a type of congenital benign melanocytic tumor.
Diagnosis:
- Diagnosis is typically made through slit lamp examination, which can visualize the presence of clear cysts within the lesion.
- In ambiguous cases, anterior segment optical coherence tomography (AS-OCT) can be used to highlight sub-clinical cysts, pointing towards a diagnosis of nevus.
Treatment:
- Conjunctival nevi are generally considered benign and do not require treatment unless they change in color or size over time.
- However, it is essential to monitor the lesion for any changes that may indicate a potential malignancy.

Signs and Symptoms
What are Conjunctival Nevus?
Conjunctival nevi, also known as freckles of the eye, are common, benign growths that can appear on or in the eye. They are similar to moles on the skin and are usually harmless.
Signs and Symptoms:
- Typically do not have any symptoms [3]
- May be mistaken for conjunctival melanoma, a rare form of cancer [4]
- Can cause changes in vision, including blurry vision [1]
- May appear as a colored growth or freckle on the eye [3]
Important Notes:
- Conjunctival nevi are usually not dangerous and do not require treatment or removal [2]
- However, it's essential to monitor them for any changes that may signal cancer [8]
- If you have a conjunctival nevus, your eye doctor may want to watch it over time [6]

Diagnostic Tests
Diagnostic Tests for Conjunctival Nevus
Conjunctival nevus, also known as eye freckle, can be diagnosed through various tests and examinations. Here are some of the diagnostic tests used to diagnose conjunctival nevus:
- Biomicroscopy: This is a crucial test in diagnosing conjunctival melanoma, which is a rare disease that makes up approximately 5% of ocular melanomas [11]. Biomicroscopy helps in identifying the lesion and assessing its extent.
- Ultrasonography: Your doctor may order ultrasonography to assess conjunctival thickness [10].
- Optical Coherence Tomography (OCT): OCT is a non-invasive imaging test that can help diagnose conjunctival melanoma by examining the thickness of the conjunctiva and detecting any abnormalities [6][11].
- Slit-lamp examination: This is a basic eye exam that can be used to identify some types of eye freckles, including choroidal nevi [12].
- Conjunctival biopsy: In some cases, a conjunctival biopsy may be necessary to confirm the diagnosis and rule out other conditions. Conjunctival biopsies are relatively common in ophthalmic pathology practices [13].
It's essential to note that not all conjunctival nevi require diagnostic testing. If the nevus is small and benign, your doctor may recommend observation only, with regular follow-ups to monitor any changes in size or color [8].

Treatment
Treatment Options for Conjunctival Nevus
Conjunctival nevi, also known as conjunctival melanocytic nevi, are benign growths on the conjunctiva, a thin membrane covering the white part of the eyes. While they are typically not dangerous and do not require treatment, some cases may need medical attention.
Topical Treatment
According to various sources [1], [2], [3], topical antiallergic agents and immunosuppressants can resolve hyperemia (redness) and pigmentation in eyes with inflamed conjunctival nevus. However, this treatment is not always necessary and may be used on a case-by-case basis.
Surgical Options
For larger or growing nevi, surgical excision may be recommended [4]. The procedure involves removing the affected area of the conjunctiva. In some cases, cryotherapy may also be used to treat conjunctival nevi [5].
Observation and Monitoring
In many cases, small, typical conjunctival nevi can be managed through periodic observation with photographs [6]. If growth is documented, local excision of the nevus may be considered.
Recovery and Complications
The recovery time for surgical procedures to treat conjunctival nevi varies depending on the individual case. In some cases, a very mild thermal brushing technique may be used to extract pigment from the surface of the conjunctiva [7]. However, this procedure is not commonly used and may have specific requirements.

Differential Diagnosis
The differential diagnosis of conjunctival nevus, also known as conjunctival melanocytic tumor, includes several conditions that can be confused with a benign or malignant neoplasm on the conjunctiva.
Conditions to Consider:
- Primary Acquired Melanosis (PAM): A pre-malignant condition characterized by flat or slightly elevated pigmented lesions on the conjunctiva [2].
- Complexion-associated Melanosis (CAM): A benign condition that can present as flat or slightly elevated pigmented lesions on the conjunctiva, often associated with skin pigmentation [1].
- Malignant Melanoma: A rare but aggressive form of cancer that can arise from the conjunctiva, often presenting as a pigmented lesion [3].
- Ocular Surface Squamous Neoplasia (OSCN): A type of cancer that affects the surface of the eye, including the conjunctiva [8].
- Lymphoproliferative and Vascular Tumors: Rare conditions that can present as pigmented lesions on the conjunctiva [8].
Key Points to Consider:
- The presence of a pigmented lesion on the conjunctiva does not necessarily indicate a malignant tumor.
- A thorough examination, including imaging studies and biopsy, is necessary to determine the correct diagnosis.
- Differential diagnosis is crucial in distinguishing between benign and malignant conditions.
