What does it mean if there is a black spot on the white part of the eye?

The white part of the eye, medically known as the sclera, may develop dark spots that could indicate the following conditions: 1. Conjunctival Pigmentation: Some people are born with pigmented spots on the sclera. These are usually normal and do not affect vision. Over time, these spots may increase in number or become darker. 2. Age-related Spots (Senile Lentigines): As people age, some may develop spots on the sclera similar to those appearing on the skin. These are related to sun exposure and genetic factors and are generally harmless. 3. Eye Injury: Trauma may cause bleeding in the sclera, forming a blood spot. As it fades over time, it may leave behind pigmentation. 4. Eye Diseases: Certain eye conditions, such as uveitis, ocular tumors, or vascular abnormalities, can also cause dark spots on the sclera. 5. Ocular Parasites: Rarely, ocular parasites such as ophthalmomyiasis (eye larva) may cause abnormalities in the sclera. Note: If you notice dark spots on the white part of your eye, it is best to consult a doctor for a thorough examination. Immediate medical attention is especially important if the spots change suddenly, are accompanied by vision loss, pain, or other discomfort.
