Maculopathy Due to Cobalamin C (cb1C) Disease in an Amish Child
Journal of Pediatric Ophthalmology and Strabismus
|October 2, 2009
Abstract:
A 5-year-old Amish boy diagnosed at birth as having a defect in intracellular cobalamin metabolism, cobalamin C disease (cb1C), presented to the pediatric ophthalmology service with severe visual impairment. Ophthalmoscopy showed bilateral bull's eye macular lesions. Visual loss occurs from retinal degeneration in cb1C disease. This report highlights the importance of post-natal metabolic testing and ophthalmic evaluation in cb1C disease, especially in high-risk inbred populations.

Photoreceptors and Visual Pathways
At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
Vitamins
Vitamins, derived from the Latin word for life, are essential organic substances required in small quantities for optimal growth and overall well-being. Unlike other organic nutrients, vitamins don't act as sources of energy or building materials but rather facilitate these nutrients' utilization by the body. Vitamins are predominantly coenzymes, assisting enzymes in specific chemical actions, like the oxidation of glucose for energy involving B vitamins. Most vitamins are not produced in our...
