Hyper-reflective foci are small bright spots seen on optical coherence tomography images. They appear within or near retinal layers and stand out due to high reflectivity. These findings are linked to inflammation, lipid deposits, or cellular changes. Their location and number can provide diagnostic clues. Doctors interpret them alongside symptoms and other imaging.

These bright spots reflect structural or cellular changes within the retina. Several contributing factors are commonly evaluated.
Doctors evaluate size, number, and location. Changes over time may reflect disease activity. Some conditions show characteristic patterns. Findings are never assessed alone. OCT trends guide monitoring decisions.
Hyper-reflective foci are tiny bright spots seen on OCT within or near retinal layers, and the meaning depends heavily on where they sit and what else is happening in the retina. In many settings, they are discussed as markers of inflammatory or cellular activity, lipid or protein-related deposits, or other microstructural changes linked to disease activity. Doctors usually track them across repeat scans to see whether they increase, decrease, or migrate, since trend over time can be more useful than a single image.
Some remain stable while others change over time. This depends on the underlying condition.
Not always. Vision impact depends on location and associated disease.
They can be linked to inflammation, but other causes exist. Context is important.
In some cases, treatment reduces their number. Doctors track changes with OCT.
