Keratocytes occupy less than what percentage of the corneal stroma?

Keratocytes are the resident cells of the corneal stroma, but they are sparsely distributed among a dense extracellular matrix of collagen lamellae. In a normal cornea, their volume fraction is quite small, typically around 5–10% of the stroma. That makes the range of 5–10% the best description for how much of the stroma keratocytes occupy. The rest of the stroma is primarily organized collagen and proteoglycans that give the cornea its strength and transparency. Variations can occur between individuals or measurement methods, but the key idea is that keratocytes are a minority component, not the major constituent of the stroma.
