101 Possible Causes for Blue Sensitive, Cone, Opsins

Did you mean: Blue, Sensitive, Cone, Opsins

  • Congenital Stationary Night Blindness

    B-Y perimetry demonstrated that blue cone sensitivity in CSNB1 was normal in the fixation area, but the mean sensitivities of the entire 60 degrees field, the central 0 degrees-to[] The results also indicate dysfunction within the cone ON pathway.[] However, without a chromophore, Ala292Glu opsin anomalously activates transducin.[]

  • Tritanopia

    Abstract Tritanopia is an autosomal dominant genetic disorder of human vision characterize by a selective deficiency of blue spectral sensitivity.[] Abstract Transient tritanopia is a cone-cone post-receptoral interaction between short-wavelength (S) cones and medium (M) and long (L) wavelength cones.[] For tritanopia , the S-opsin gene must be introduced instead of M-opsin gene.[]

  • Achromatopsia

    A 19-year-old affected man was a classical blue cone monochromat on color matching and spectral sensitivity.[] Cone density and reflectivity were quantified to assess residual cone photoreceptor structure.[] Using AAV vectors administered by subretinal injection, we evaluated a series of promoters based on the human L-opsin promoter, or a chimeric human cone transducin promoter[]

  • Goldmann-Favre Syndrome

    With S cone perimetry, the patients had normal or subnormal S cone function.[] Cryosections were studied by indirect immunofluorescence, using well-characterized antibodies to rhodopsin, cone cytoplasm, and cone opsins.[] These large, slow waveforms persist without change under light adaptation, and there is greater sensitivity to blue light stimuli.[]

  • Blue Cone Monochromatism

    In this condition both red and green cone sensitivities are absent, however rod function and blue cone sensitivities are present.[] Abstract Blue cone monochromatism (BCM) is a subtype of achromatopsia in which the blue cone mechanism predominates.[] CONCLUSIONS: Hybrid red/green opsin genes carrying the Cys203Arg mutation are a frequent cause of BCM in German patients.[]

  • Retinoid

    It should be discontinued if hypersensitivity is noted.[] RT-PCR was performed to detect the cone alpha'-subunit of cGMP phosphodiesterase (cone alpha'-PDE), the rod beta-subunit of cGMP (rod beta-PDE), and the interphotoreceptor[] Abstract Previously, immunoreactive rod-opsin and S-antigen (arrestin), two highly characteristic markers of retinal photoreceptors and pinealocytes, were shown to be present[]

  • Progressive Cone Dystrophy

    METHODS: Local cone system function was assessed by measuring cone system thresholds (visual fields) and cone-mediated multifocal electroretinograms (mfERGs).[] […] genes (L- and M-opsin genes).[] For example, to cope with their hypersensitivity to light outdoors, some networkers wear very dark amber lenses or very dark brown lenses, some wear deep red lenses, and some[]

  • Night Blindness

    Rod and cone photoreceptor (R(ROD), S(ROD), R(CONE), S(CONE)) and rod-driven postreceptor (V(MAX), log σ) response parameters were calculated from the a- and b-waves.[] […] genetic defects, as well as the relative normalcy of vision in individuals with half the complement of wild type rhodopsin, suggest that it is an active property of the mutant opsin[] ‘Affected individuals are sensitive to blue light and develop night blindness at an early age.’[]

  • Nephronophthisis

    The retinal function in this case was identical with that in the classic type of sector retinitis pigmentosa, namely, subnormal ERG amplitudes but normal cone and rod implicit[] We show that Ahi1-null mice fail to form retinal outer segments and have abnormal distribution of opsin throughout their photoreceptors.[] Avoid if allergic or hypersensitive to oregano.[]

  • Macular Degeneration

    First, there are no blue sensitive cones at the centre of the fovea, thus, visible blue light cannot contribute to visual performance and experience at the location of maximum[] […] instead of the L-cone and M-cone opsin gene arrays.[] On the other hand, less mature cells have more self-renewal properties and possibly more potential to integrate and repair the eye’s rods and cones.[]
