Conjunctival Pigmentations, Right Eye: Causes and Symptoms

Conjunctival pigmentations refer to the presence of abnormal coloration on the conjunctiva, the clear membrane that covers the white part of the eye, known as the sclera. These pigmentations can occur in either or both eyes and are usually harmless. However, it is crucial to understand their causes and symptoms to ensure proper diagnosis and management.

Causes:

1. Melanosis: Melanosis is the most common cause of conjunctival pigmentations. It occurs when there is an increased production of melanin, the pigment responsible for the color of our skin, hair, and eyes. Melanosis can be triggered by various factors, such as aging, ultraviolet (UV) radiation exposure, and hormonal changes.
2. Pinguecula: Pinguecula is a yellowish or whitish bump that develops on the conjunctiva, usually near the cornea. Although it is not a pigmentation per se, it can cause localized discoloration and may be mistaken for a conjunctival pigmentation. Pinguecula is often associated with long-term exposure to sunlight and environmental irritants.
3. Nevi: Conjunctival nevi are benign pigmented lesions that arise from melanocytes, the cells responsible for producing melanin. Nevus can be present at birth or develop later in life. While most conjunctival nevi are harmless, some may require monitoring to ensure they do not undergo malignant transformation.
4. Pterygium: A pterygium is a growth of pink, fleshy tissue that extends from the conjunctiva over the cornea. Although not a pigmentation, it can cause localized discoloration due to its appearance. Pterygium is often associated with excessive exposure to UV radiation and dry environments.
