This enzyme cleaves the COMPLEMENT C3B-bound COMPLEMENT FACTOR B to form C3bBb which is ALTERNATIVE PATHWAY C3 CONVERTASE.Fluorescence: The property of emitting radiation while being irradiated. The radiation emitted is usually of longer wavelength than that incident or absorbed, e.g., a substance can be irradiated with invisible radiation and emit visible light. X-ray fluorescence is used in diagnosis.Retinal Dystrophies: A group of disorders involving predominantly the posterior portion of the ocular fundus, due to degeneration in the sensory layer of the RETINA; RETINAL PIGMENT EPITHELIUM; BRUCH MEMBRANE; CHOROID; or a combination of these tissues.Infrared Rays: That portion of the electromagnetic spectrum usually sensed as heat. Infrared wavelengths are longer than those of visible light, extending into the microwave frequencies. They are used therapeutically as heat, and also to warm food in restaurants.Retinal Photoreceptor Cell Inner Segment: The inner portion of a retinal rod or a cone photoreceptor cell, situated between the PHOTORECEPTOR CONNECTING CILIUM and the synapse with the adjacent neurons (RETINAL BIPOLAR CELLS; RETINAL HORIZONTAL CELLS). The inner segment contains the cell body, the nucleus, the mitochondria, and apparatus for protein synthesis.Eye Protective Devices: Personal devices for protection of the eyes from impact, flying objects, glare, liquids, or injurious radiation.Extracellular Matrix Proteins: Macromolecular organic compounds that contain carbon, hydrogen, oxygen, nitrogen, and usually, sulfur. These macromolecules (proteins) form an intricate meshwork in which cells are embedded to construct tissues. Variations in the relative types of macromolecules and their organization determine the type of extracellular matrix, each adapted to the functional requirements of the tissue. The two main classes of macromolecules that form the extracellular matrix are: glycosaminoglycans, usually linked to proteins (proteoglycans), and fibrous proteins (e.g., COLLAGEN; ELASTIN; FIBRONECTINS; and LAMININ).Rod Cell Outer Segment: The portion of a retinal rod cell situated between the ROD INNER SEGMENT and the RETINAL PIGMENT EPITHELIUM. It contains a stack of photosensitive disk membranes laden with RHODOPSIN.Polymerase Chain Reaction: In vitro method for producing large amounts of specific DNA or RNA fragments of defined length and sequence from small amounts of short oligonucleotide flanking sequences (primers). The essential steps include thermal denaturation of the double-stranded target molecules, annealing of the primers to their complementary sequences, and extension of the annealed primers by enzymatic synthesis with DNA polymerase. The reaction is efficient, specific, and extremely sensitive. Uses for the reaction include disease diagnosis, detection of difficult-to-isolate pathogens, mutation analysis, genetic testing, DNA sequencing, and analyzing evolutionary relationships.Microscopy, Electron: Microscopy using an electron beam, instead of light, to visualize the sample, thereby allowing much greater magnification. The interactions of ELECTRONS with specimens are used to provide information about the fine structure of that specimen. In TRANSMISSION ELECTRON MICROSCOPY the reactions of the electrons that are transmitted through the specimen are imaged. In SCANNING ELECTRON MICROSCOPY an electron beam falls at a non-normal angle on the specimen and the image is derived from the reactions occurring above the plane of the specimen.Dietary Supplements: Products in capsule, tablet or liquid form that provide dietary ingredients, and that are intended to be taken by mouth to increase the intake of nutrients. Dietary supplements can include macronutrients, such as proteins, carbohydrates, and fats; and/or MICRONUTRIENTS, such as VITAMINS; MINERALS; and PHYTOCHEMICALS.Cell Survival: The span of viability of a cell characterized by the capacity to perform certain functions such as metabolism, growth, reproduction, some form of responsiveness, and adaptability.RNA, Messenger: RNA sequences that serve as templates for protein synthesis. Bacterial mRNAs are generally primary transcripts in that they do not require post-transcriptional processing. Eukaryotic mRNA is synthesized in the nucleus and must be exported to the cytoplasm for translation. Most eukaryotic mRNAs have a sequence of polyadenylic acid at the 3' end, referred to as the poly(A) tail. The function of this tail is not known for certain, but it may play a role in the export of mature mRNA from the nucleus as well as in helping stabilize some mRNA molecules by retarding their degradation in the cytoplasm.Antibodies, Monoclonal: Antibodies produced by a single clone of cells.Paraneoplastic Cerebellar Degeneration: Cerebellar degeneration associated with a remote neoplasm. Clinical manifestations include progressive limb and GAIT ATAXIA; DYSARTHRIA; and NYSTAGMUS, PATHOLOGIC. The histologic type of the associated neoplasm is usually carcinoma or lymphoma. Pathologically the cerebellar cortex and subcortical nuclei demonstrate diffuse degenerative changes. Anti-Purkinje cell antibodies (anti-Yo) are found in the serum of approximately 50% of affected individuals. (Adams et al., Principles of Neurology, 6th ed, p686)

  • Patients exhibit macular schisis and peripheral schisis, which can mimic retinal detachment, a very different entity that requires surgical intervention. (biomedcentral.com)
  • Following treatment with topical dorzolamide 2 % for 18 months, there was dramatic regression of both macular and peripheral schisis cavities in the nonoperative eye. (biomedcentral.com)
  • Increased levels of VEGF also result in the development of macular edema. (molvis.org)
  • Late-Vision loss and macular damage are present, along with drusen. (denverhealth.org)
  • Hageman, Gregory S 2000-02-01 00:00:00 PURPOSE: To determine whether basal laminar drusen differ in their location, ultrastructure, or composition from drusen associated with aging and age-related macular degeneration. (deepdyve.com)
  • their substructure is indistinguishable from drusen phenotypes in age-related macular degeneration. (deepdyve.com)
  • Both basal laminar drusen and drusen associated with age-related macular degeneration are bound by the lectins Ricinis communis agglutinin and Arachis hypogea agglutinin (after neuraminidase digestion) and by antivitronectin, anti-HLA-DR, anti-serum amyloid P, and anti-C5 antibodies, but not by antibodies directed against basement membrane-associated heparan sulfate proteoglycan, laminin, fibrinogen, or collagen type IV. (deepdyve.com)
  • CONCLUSIONS: These data support the notion that cuticular or basal laminar drusen are similar to, and perhaps indistinguishable from, drusen associated with age-related macular degeneration and are not nodular or diffuse thickenings of Bruch membrane, as previously suggested. (deepdyve.com)
  • At this point, careful macular exam shows subtle pigmentary changes and some drusen. (healio.com)
  • It may be beneficial to perform an OCT if there is any doubt of drusen or pigmentary changes or if the view from the cataract is sufficiently poor to preclude fine macular exam. (healio.com)
  • For the 145 participants completing the study, the researchers found that there were significant increases in plasma concentrations of the administered carotenoids as well as the optical density of the macular pigment in the groups randomized to receive supplementary macular xanthophylls and ω-3 LC-PUFAs after one month of intervention.
