Inquiry about the sclera (the white part of the eye)?

Hello, Dr.
Gao: I would like to ask you about something.
When I pull down the lower eyelid of my left eye, revealing the sclera (the white part of the eye), I notice a faint black circular spot on the sclera.
Below this spot, there are twisted, thin red blood vessels, and it seems to be flat.
In the same position of my right eye, there is a similar faint black circular spot, but it is located slightly lower, surrounded by twisted, thin red blood vessels.
The faint black circular spots on the sclera of both my eyes can only be seen when I pull down the eyelid or look upward, and I have the impression that they have been present for a long time without any discomfort.
Dr.
Gao, in your opinion, what could these faint black circular spots connected to the twisted, thin red blood vessels on the sclera of my eyes be? Thank you for your clarification, Dr.
Gao.

Hello! Thank you for your question regarding the dark spots on the sclera (the white part of the eye) and the associated red blood vessels. It's understandable to be concerned about changes in your eyes, and I’m here to provide some insights.

The dark spots you are observing on your sclera could be a few different things, but one common possibility is a condition known as a "conjunctival nevus." A conjunctival nevus is a benign (non-cancerous) growth of pigmented cells on the conjunctiva, which is the clear membrane covering the sclera and the inner surface of the eyelids. These nevi can appear as small, flat, or slightly raised dark spots and are usually harmless. They can vary in color from light brown to dark black and often have associated blood vessels, which may appear as red or pink lines.

Another possibility is a "pinguecula," which is a yellowish, slightly raised growth on the conjunctiva that can sometimes appear darker depending on the pigmentation. Pingueculae are typically caused by UV exposure, dry eyes, or irritation from environmental factors. They are also benign and usually do not require treatment unless they become bothersome.

If the spots are new, changing in appearance, or accompanied by symptoms such as irritation, redness, or vision changes, it is essential to consult an eye care professional for a thorough examination. They can provide a definitive diagnosis and determine if any treatment is necessary.

It's worth noting that while these conditions are generally benign, any new or unusual changes in your eyes should be evaluated by an ophthalmologist, especially if you have a history of eye problems or if you notice any changes in your vision.

In summary, the dark spots on your sclera, especially if they have been present for a long time without any discomfort, are likely benign conditions such as a conjunctival nevus or pinguecula. However, it is always best to have any concerns about your eyes evaluated by a healthcare professional to ensure your eye health is maintained.

If you have any further questions or concerns, please feel free to ask!
