Margin reflex distance 1 or MRD1 is determined by the examiner and patient aligning at the same level. MRD1 is used to indicate degree of ptosis or retraction. See below image. MRD2 is useful for calculations involving reverse ptosis such as seen in Horner syndrome , or lower eyelid retraction. Margin reflex distance 3 or MRD3 is an entity described by Putterman, which is the distance from the ocular, not corneal, light reflex to the central upper-eyelid margin when the patient looks in extreme up gaze. Margin limbal distance or MLD is used by some surgeons to measure levator function to determine the amount of levator muscle to resect.

Metachromatic leukodystrophy MLD is a lysosomal storage disease which is commonly listed in the family of leukodystrophies as well as among the sphingolipidoses as it affects the metabolism of sphingolipids. MLD involves cerebroside sulfate accumulation. Like many other genetic disorders that affect lipid metabolism, there are several forms of MLD, which are late infantile , juvenile , and adult. Palliative care can help with many of the symptoms and usually improves quality of life and longevity. Carriers have low enzyme levels compared to their family population "normal" levels vary from family to family but even low enzyme levels are adequate to process the body's sulfatide. The myelin sheath is a fatty covering that protects nerve fibers. Without it, the nerves in the brain central nervous system — CNS and the peripheral nerves peripheral nervous system — PNS which control, among other things the muscles related to mobility, cease to function properly. Arylsulfatase A is activated by saposin B Sap B , a non-enzymatic proteinaceous cofactor. A study contended sulfatide is not completely responsible for MLD because it is nontoxic. It has been suggested lysosulfatide, sulfatide which has had its acyl group removed, plays a role because of its cytotoxic properties in vitro. MLD has an autosomal recessive inheritance pattern. The inheritance probabilities per birth are as follows: [8]. With the current diagnostic tests, Pseudo-deficiency reports as low enzyme levels but sulfatide is processed normally so MLD symptoms do not exist. This phenomenon wreaks havoc with traditional approaches to Newborn Screening so new screening methods are being developed. Genomic sequencing may also confirm MLD, however, there are likely more mutations than the over already known to cause MLD that are not yet ascribed to MLD that cause MLD so in those cases a biochemical test is still warranted.

Metachromatic leukodystrophy is a lysosomal storage disease, which is characterized by damage of the myelin sheath that covers most of nerve fibers of the central and peripheral nervous systems. The disease occurs due to a deficiency of the lysosomal enzyme arylsulfatase A ARSA or its sphingolipid activator protein B SapB and it clinically manifests as progressive motor and cognitive deficiency.

What can you tell me about metachromatic leukodystrophy? My granddaughter was just diagnosed, but she has two older siblings who are perfectly healthy. How is that possible? Metachromatic leukodystrophy MLD is an inherited disorder that affects the protective covering around nerve cells myelin sheath , as well as the nerve fibers that the sheath insulates and protects.
