    ERG and EOG abnormalities in carriers of X-linked retinitis pigmentosa

    The diagnosis of X-linked retinitis pigmentosa (XL-RP) relies on the identification of the female carriers, in whom fundal abnormalities are often minimal and variable. The electroretinogram (ERG) has been rep...

    Induced intraocular light scatter and the sensitivity gradient of the normal visual field

    The influence of intraocular light scatter on the perimetric sensitivity profile of the normal eye was investigated using a series of light-scattering cells containing 0.01%, 0.02% and 0.025% concentrations of...

    Some concepts on the use of three-dimensional isometric plots for the representation of differential sensitivity

    An increasing use is being made of three-dimensional isometric plotting to represent the topography of the visual field. The format of such plots, however, can be manipulated depending upon the parameters of t...

    The role of intraocular light scatter in the attenuation of the perimetric response

    The relationship between perimetric attenuation and intraocular light scatter was investigated in normal subjects using latex bead cells and in patients with uniocular media opacities. The Octopus 201 and Dico...
