periskeletal

Starting at approximately one month of age and continuing for the next two years, the scleral ossicles of SF elongate via unilateral periskeletal ossification and fuse to form a continuous bony ring that eventually covers 90% or more of the circumference of the eye, while the sclera of CF remain cartilaginous, stop growing, and eventually form a cyst around the degenerating eye.
