How long does it typically take for stromal healing to occur, leading to corneal fibrosis?

Stromal healing in the cornea leading to corneal fibrosis typically occurs over a timeframe of days to weeks. This healing process is influenced by various factors, including the severity of the injury, the presence of inflammation, and the overall health of the ocular surface.

During the initial healing phase, fibroblasts migrate to the injury site, and collagen production increases, contributing to the formation of scar tissue, or fibrosis. This process generally begins shortly after the injury and can continue over the course of several weeks, leading to noticeable changes in the corneal structure.

A timeframe of months to years would be too prolonged for initial stromal healing and fibrotic changes to take place, while hours to days is typically too short for significant healing processes to occur. Therefore, the correct answer aligns with the biological healing response seen in the corneal stroma after an injury.
