Can crying cause a subconjunctival hemorrhage?

Yes, crying can potentially cause a subconjunctival hemorrhage. When a person cries, the increased pressure on the small blood vessels in the eye can cause them to rupture, leading to a subconjunctival hemorrhage. This type of hemorrhage occurs when blood accumulates under the conjunctiva, the thin, clear membrane that covers the white part of the eye. It typically appears as a bright red or dark red patch on the white of the eye. While crying is a common trigger, other factors such as coughing, sneezing, or vigorous physical activity can also cause a subconjunctival hemorrhage. In most cases, a subconjunctival hemorrhage is not a serious condition and will resolve on its own within a few weeks without any treatment. However, if the hemorrhage is severe or accompanied by other symptoms such as pain, vision changes, or swelling, it's important to consult an eye doctor for further evaluation and management.
