On an infrared image, how would exudates appear?

Explanation:
Exudates show up as bright, white areas on infrared images because they are lipid-rich deposits that reflect infrared light more strongly than the surrounding retinal tissue. Infrared light penetrates and interacts with different tissue components in ways that highlight differences in reflectivity, so the lipid-laden exudates stand out as hyperreflective (bright) regions against a relatively darker retina. This contrast makes them appear white on IR imaging.
