• adult mice display abnormal fibril structure and stromal disorganization
• larger and less uniform collagen fibrils are seen throughout the cornea stroma, with disrupted fibril packing
• a significant decrease in fibril density and inter-fibril space is noted in both anterior and posterior regions of the stroma
|
|
• adult mice exhibit a 14% decrease in corneal stroma thickness relative to wild-type controls
|
|
• in the anterior stroma, the mean stromal fibril diameter increased to 42.5+/-12.8 nm versus 25.3+/-3.4 nm in control corneas
• the range of anterior stroma fibril diameters is 8-95 nm versus 14-42 nm in control corneas
• a 58% decrease in the number of fibrils per unit area is noted in the anterior stroma
|
|
• in the posterior stroma, the mean stromal fibril diameter increased to 34.7+/-6.7 nm versus 27.5+/-3.3 nm in control corneas
• the range of posterior stroma fibril diameters is 12-61 nm versus 14-39 nm in control corneas
• a 36% decrease in the number of fibrils per unit area is noted in the posterior stroma
|
|
• at P30 and P90, mice exhibit a heterogeneous collagen fibril population containing fibrils with very large diameters
• structurally abnormal fibrils with irregular profiles are commonly observed
• the fibril phenotype shows an anterior-posterior difference, with the anterior stroma containing larger and more heterogeneous fibrils than the posterior stroma
• a significant decrease in fibril density is noted in both anterior and posterior regions of the stroma
|
|
• adult mice exhibit conspicuous corneal stromal opacity
• at P60, backscattered light is observed throughout the corneal stroma, with more haze in the anterior stroma
|
|
• mice exhibit a 3.5-fold increase in the average light scattering per micrometer thickness of the corneal stroma relative to wild-type controls

• mice are viable and fertile with no significant differences in body weight at P10 or P30 relative to wild-type controls
