Pooling in relation to hyperfluorescence refers to the concentration of a dye in a specific area, resulting in an increased level of fluorescence in that localized region. This phenomenon typically occurs when there is an accumulation of dye in tissue or cells, leading to a brighter signal in imaging studies. This concentrated fluorescence can be indicative of particular physiological or pathological conditions, such as leakage from blood vessels or increased vascular permeability.

In contrast, a uniform distribution of dye signifies an even spread across a tissue or structure, which would not be characteristic of pooling. Likewise, an absence of dye would suggest no fluorescence at all, and a random spread of dye would imply that there is no defined concentration, both of which do not align with the concept of pooling. The key aspect of pooling is the localized accumulation that leads to hyperfluorescence, making the first description the most accurate.
