Hard exudates are primarily found in which retinal layer?

Explanation:
Hard exudates come from lipid-rich leakage that accumulates in the outer retina. They are most commonly found in the outer plexiform layer, the region where photoreceptors connect with bipolar cells, allowing lipid debris to deposit extracellularly. This distinguishes them from soft exudates, which reflect ischemia and sit in the nerve fiber layer of the inner retina. The other layers listed host different neural structures and are not the usual sites for lipid deposits from chronic leakage, making the outer plexiform layer the correct location.
