**Core Concept**
Subconjunctival hemorrhages occur due to the rupture of small blood vessels in the conjunctiva, leading to bleeding under the conjunctiva. This is often a result of increased intraocular pressure, trauma, or vasculitis.

**Why the Correct Answer is Right**
Subconjunctival hemorrhages are commonly associated with conditions that increase intraocular pressure, such as glaucoma, or those that cause trauma to the eye, like a blow to the head. Vasculitis, an inflammation of the blood vessels, can also lead to the rupture of these small vessels.

**Clinical Pearl / High-Yield Fact**
Subconjunctival hemorrhages are often self-limiting and resolve on their own within 2-3 weeks. However, if the hemorrhage is large or does not resolve, it may be a sign of an underlying condition that requires further investigation.
