Figure 2. Cystine crystal quantification measured as the percentage (%) of crystals per stromal volume over time. We observed a progressive increase in the crystal content in corneas from 3 to 8 months of age. However, at 10 months of age, crystal volume appeared to decrease due to breakdown of crystals and/or scarring. A: The average and standard deviation values over time. B: All the individual eyes that were followed over 10 months.
