Abstract

One of the classical symptoms of Retinitis Pigmentosa is the gradual loss of vision in the periphery, first detected as a ring- or horseshoe-shaped scotoma in the mid-periphery. Using a Goldmann perimeter, such a scotoma can first be documented with small targets, e.g. II/4e. Subsequently it slowly increases in density and extent: a V/4e target may reveal the scotoma as much as ten years later than the II/4e target.
