Long-term visual prognoses in patients with retinitis pigmentosa: the Ludwig von Sallmann lecture
EL Berson - Experimental eye research, 2007 - Elsevier
Retinitis pigmentosa can be followed over almost its entire course with narrow bandpassed,
computer averaged cone electroretinograms (ERGs). The long-term rate of decline of these
responses can be described by an exponential function. A cone ERG actuarial table based
on 1039 patients and 6553 visits is presented to show the estimated number of years for an
average patient with a given 30-Hz cone ERG amplitude to decline to 0.05 μV (ie virtual
blindness). The table is based on a projected rate of loss of 10% of remaining cone ERG …
