Purple eyes are usually caused by subcutaneous hemorrhage or hemangioma in the orbital area. When the eye is traumatized, resulting in subcutaneous bruising of the eyelid or spontaneous hemorrhage in the orbit due to abnormal coagulation, the blood will penetrate into the lower part of the skin of the eye, forming a blue-purple patch, which will cause the patient’s eyes to turn purple. In the early stage of ocular trauma causing subcutaneous bruising, patients can apply local cold compresses to the eyes to promote hemostasis, and after 48 hours, local hot compresses can be applied to promote the absorption of bleeding. If the congenital developmental abnormalities lead to the formation of hemangioma in the orbit, it will also lead to the patient’s eyes purple, mostly due to the hemangioma in the stagnation of a large amount of blood through the skin to reveal the color, the patient can be diagnosed through the orbital ultrasound, orbital CT examination. It is recommended that patients with obvious purple eyes should consult the hospital in time to assess their condition and under the guidance of the doctor for treatment.
