How long does it take for a subconjunctival hemorrhage to heal?

　　In most cases, subconjunctival hemorrhage can gradually be absorbed and heal within 1 to 2 weeks. However, recovery may take longer if the bleeding area is large or the individual has poor overall health. If there are concerns, it is advisable to seek medical consultation promptly. Detailed analysis is as follows:

　　If the area of subconjunctival hemorrhage is small, the patient has no underlying conditions such as hypertension or diabetes, and proper eye protection is maintained without re-injury, the bleeding typically begins to resolve within about one week and usually returns to normal within two weeks. During this period, there are generally no significant discomforts other than a visible red patch on the eye. As the blood is absorbed, the color of the patch will gradually change from bright red to pale yellow before eventually disappearing completely.

　　If the hemorrhage covers a larger area, or if the patient is older, has coagulation disorders, or is taking anticoagulant medications long-term, recovery may extend to 2–3 weeks or even longer. Some patients may experience mild dryness or foreign body sensation in the eye and require more time for complete absorption of the blood. Close monitoring is necessary during this period for any signs of expanding hemorrhage, vision loss, or other abnormalities to avoid delays in addressing potential complications.

　　After subconjunctival hemorrhage occurs, cold compresses within the first 48 hours can help reduce bleeding, followed by warm compresses after 48 hours to promote absorption. Avoid rubbing the eyes and engaging in strenuous physical activity to prevent worsening of the bleeding. If symptoms such as eye pain, blurred vision, or recurrent bleeding occur, prompt medical evaluation is recommended to rule out underlying ocular or systemic diseases.
