Leukodystrophy is one of a group of disorders characterized by degeneration of the white matter in the brain. The word leukodystrophy comes from the Greek roots leuko, white, dys, abnormal, and troph, growth. The leukodystrophies are caused by imperfect growth or development of the myelin sheath, the fatty covering that acts as an insulator around nerve fibers. When damage occurs to white matter, immune responses can lead to inflammation in the CNS, along with loss of myelin. The degenerat
A corneal laceration can be a partial- or full-thickness injury to the cornea. A partial-thickness injury does not violate the globe of the eye (abrasion). A full-thickness injury penetrates completely through the cornea, causing a ruptured globe. This topic discusses the full-thickness injury.
If an ulcer becomes deep, a perforation of the cornea may result. A laceration is often the result of a traumatic âtearâ or âcutâ to the cornea surface that often penetrates into the eye. In either case, intraocular infection may result with loss of vision, pain, and possibly loss of the eye.Aggressive medical and surgical therapy is often indicated. laceration is often the result of a traumatic âtearâ or âcutâ to the cornea surface that often penetrates into the eye.
