Much of the debris is removed by macrophages. 4, As the scar matures, the fibroblasts subside. Newly formed blood vessels recanalize . New collagen strengthens the wound, which contracts. Note that the striated muscle cells (permanent cells) at bottom are replaced by sca r (arrow). Figure 2-1 fibrils, takes 4-6 weeks. The epithelial cells are labile; that is, some are continuously active mitotically and thus are able to completely replace the lost cells. If a thin layer of anterior cornea is lost with the abrasion, the shallow crater will be filled by epithelium, forming a facet.
The retina is anchored anteriorly to the nonpigmented epithelium of the pars plana. This union is reinforced by the attachment of the vitreous base, which straddles the ora serrata. Deformation of the eye can result in a circumferential retinal tear at the point of attachment of the ora or immediately posterior to the point of attachment of the vitreous base. Vitreoretinal traction may cause tears in a retina weakened by necrosis. Intraocular fibrocellular proliferation may occur after a penetrating injury.
