Dark Spots on Whites of Eyes Causes, Symptoms, and Treatment Options

When we think about eye health, we often focus on the clarity of our vision and the well-being of our cornea and retina. However, it’s important not to overlook the appearance of the whites of our eyes, known as the sclera. Dark spots or patches on the sclera can be concerning and may indicate an underlying issue. In this blog post, we will explore the possible causes of dark spots on the whites of the eyes, common symptoms to look out for, and available treatment options.

Common Causes of Dark Spots on Whites of Eyes

1. Pinguecula Pinguecula is a common condition characterized by yellowish or grayish raised spots on the sclera near the cornea. These spots are typically caused by exposure to UV light, dust, wind, or dryness. While pinguecula is usually harmless, it can sometimes cause discomfort or inflammation.

2. Pterygium Similar to pinguecula, a pterygium is a growth on the conjunctiva, which is the thin tissue covering the sclera. It often starts as a pinkish spot and can grow into a fleshy, triangular-shaped tissue that extends onto the cornea. Pterygium is also associated with UV exposure and can cause redness, irritation, and blurred vision.

3. Subconjunctival Hemorrhage A subconjunctival hemorrhage occurs when a small blood vessel in the conjunctiva ruptures, leading to the appearance of a red or dark spot on the sclera. This can happen due to minor trauma, eye rubbing, straining, or even spontaneously. Subconjunctival hemorrhages are typically harmless and resolve on their own within a couple of weeks.

4. Nevus A nevus, also known as an eye freckle, is a pigmented spot on the sclera caused by the accumulation of melanocytes. These spots are usually benign and do not require treatment unless they change in size, shape, or color over time.

5. Melanoma While rare, melanoma can develop on the whites of the eyes. Dark spots or pigmented lesions that grow, change shape, or cause symptoms such as blurred vision or discomfort should be evaluated by an eye care professional.

Treatment Options and Management

The treatment options for dark spots on the whites of the eyes depend on the underlying cause. Here are some common approaches

1. Lubricating Eye Drops In cases where dryness or irritation contributes to the appearance of dark spots, lubricating eye drops can help alleviate symptoms and reduce discomfort.

2. UV Protection Wearing sunglasses that provide 100% UV protection can help prevent or minimize the development of pinguecula and pterygium by shielding the eyes from harmful UV radiation.

3. Observation and Monitoring In cases of benign conditions such as pinguecula, pterygium, or nevi, observation and regular eye exams may be recommended to monitor any changes in size, shape, or color.

4. Surgical Intervention If a pterygium causes significant discomfort or affects vision, surgical removal may be necessary. However, it is generally reserved for more severe cases.

5. Medical Evaluation If dark spots on the whites of the eyes are concerning, persist, or show signs of growth, it is essential to seek professional evaluation from an eye care specialist. They can perform a comprehensive eye examination and determine the appropriate course of action.

Dark spots on the whites of the eyes can be a cause for concern, but in many cases, they are benign and do not require treatment. Pinguecula, pterygium, subconjunctival hemorrhages, nevi, and, rarely, melanoma can all contribute to the appearance of dark spots. If you notice any changes, discomfort, or vision disturbances associated with these spots, it is crucial to seek professional evaluation. Regular eye exams and protective measures such as UV protection can help maintain eye health and prevent the development of these spots. Remember, early detection and appropriate management are key to maintaining healthy eyes and vision.
