Ocular infiltrates may include which cellular component?

• A. Cells (abscess/necrosis - white/yellow, eosinophils, neoplasia)
• B. Capillaries
• C. Collagen fibers
• D. Vitreous humor

Answer: (A)

Ocular infiltrates are accumulations of cellular material within ocular tissues, reflecting the presence of inflammatory or neoplastic cells rather than just fluid or structural components. The best answer is that infiltrates can consist of cells such as those seen in abscesses or necrotic tissue (which appear white or yellow due to pus), eosinophils in certain inflammatory or allergic contexts, and even neoplastic cells that invade ocular structures. This cellular content defines an infiltrate.

The other options are not cellular infiltrates. Capillaries are blood vessels, not cellular accumulations. Collagen fibers are part of the connective tissue framework, not infiltrating cells. Vitreous humor is the gel-like fluid inside the eye, not cellular material.
