Pseudopapilloedema with and without verified optic disc drusen. A clinical analysis II: visual fields.

An analysis of visual field findings in the material of 200 patients with pseudopapilloedema with and without verified optic disc drusen was performed. Goldmann and/or Friedmann visual fields were examined in 383 eyes. Visual field defects were found in 38.9% of the pseudopapilloedema eyes without verified drusen, but in 73.4% of the drusen eyes. The strongest field defects were found only in the eyes with drusen seen by oblique illumination or with superficial drusen. The eyes with superficial drusen showed visual field defects in 85.8%. Only 7 patients complained of visual field defects. A progression of visual field defects could be documented in 22% of 118 patients with visual field examinations 2 or more times.
