Which description best fits the appearance of a retinal hemorrhage?

A retinal hemorrhage typically presents as poorly circumscribed and raised. This description fits because retinal hemorrhages occur when blood leaks into the retinal tissue, leading to the formation of localized, raised areas due to the accumulation of blood. These hemorrhagic areas are often irregularly shaped and can vary in size, creating an appearance that is less defined compared to other ocular findings.

The other descriptions do not match the characteristic appearance of retinal hemorrhages. For instance, a flat and hyperreflective appearance is more relevant to certain types of lesions or reflective surfaces within the eye, while well-defined and scarring would suggest the presence of other abnormalities, such as scars from previous injury or disease. Clear and linear does not align with the nature of retinal hemorrhages, as they are marked by the presence of blood, which would not be clear or linear in its appearance. Thus, the association of a retinal hemorrhage with a poorly circumscribed and raised morphology is accurate.
