Fig. 63. Rupture of the posterior sclera following blunt trauma. A. The sclera has ruptured immediately posterior to the insertion of a rectus muscle. The area of the rupture may not be identified unless surgical exploration is directed to visualize the vulnerable areas of rectus and superior oblique muscle insertion. B. The histologic section demonstrates that the rupture extended to the adjacent choroid and retina. (Hematoxylin-eosin stain; × 5.)
