What does a subconjunctival hemorrhage appear as?

A subconjunctival hemorrhage presents as a bright red spot on the white part of the eye, known as the sclera. This occurs when small blood vessels break under the conjunctiva, the clear membrane covering the sclera, leading to bleeding that becomes visible as a red area. This condition is typically benign and can result from activities that increase pressure in the vessels, such as heavy lifting, coughing, or straining.

In contrast, the other options describe different ocular conditions. A dark spot on the pupil could refer to a number of issues, including a foreign body or pigmentation but not subconjunctival hemorrhage. A cloudy area in the lens is indicative of a cataract, while a yellow stain on the cornea suggests conditions such as corneal staining or deposits that are not related to a hemorrhage. Thus, the identification of a subconjunctival hemorrhage as a red spot on the sclera is accurate and aligns with clinical observations.
