Blue eyes need to be alerted to the possibility of scleritis, scleral staphyloma, and other conditions.
Blue eyes are usually caused by the thinning of the sclera, which reveals the color of the deep choroidal blood vessels. The choroidal blood vessels are rich in venous blood and therefore appear blue-violet through the sclera. There are many diseases that cause thinning of the sclera, such as scleritis and scleral staphyloma.
1. Scleritis: usually caused by autoimmune reaction, patients will have red eyes, eye pain and other symptoms in the early stage of the disease, and then the sclera may appear limited thinning, resulting in blue white of the eye.
2. Scleral staphyloma: due to local scleral thinning and protrusion and the formation of the early onset of local bluish eyes, with the aggravation of the disease and even local black color, until ulceration occurs.
The appearance of blue eyes, should consult a doctor in time, follow the doctor’s instructions for treatment.
