vision/eye
• Relative to C57BL/6J controls, homozygotes develop a smaller posterior eye and shorter posterior chamber depth leading to a shorter axial length, although the anterior chamber depth is longer, and decreased corneal radius of curvature
|
• the angle is narrow and the iris is closely apposed to the trabecular meshwork
|
• focally hypoplastic with substantially reduced collagen fibrils in the trabecular beams and an increase in open spaces lacking extracellular matrix
|
• in some mice at 3 months of age
|
• With age there is a slight increase in lens thickness
|
• variable decrease (ranging from 0-10% shorter than in controls) in axial length at 2 months of age
|
• in severely affected mice
(J:188765)
• Background Sensitivity: reduction in axial length is more severe in mice on an inbred C3H/HeA background than in mice on a C57BL/6 background

)
• progressing with age
|
• focal regions with abnormal crowding of collagen fibrils
|
• expanded and thicker by as early as 2 months of age
|
• pupil dilation induces a large increase in intraocular pressure
|
• the refractive error was found to be slightly increased at 10 weeks of age, shifting toward hyperopia, but to a lesser degree than caused by the em2(IMPC)J null allele of this gene
