Pseudopapilloedema with and without verified optic disc drusen. A clinical analysis I.

A clinical analysis of 200 patients (307 eyes with optic disc drusen, 40 eyes with pseudopapilloedema without verified drusen, 53 normal fellow-eyes) was performed to document the characteristic findings in pseudopapilloedema with and without verified drusen. In 4 eyes optic disc drusen accounted for diminished visual acuity. Papillary or peripapillary haemorrhages were found in 6.1% of 347 eyes. Peripapillary pigment epithelial derangement was present in 29.7% of the eyes, mostly with superficial drusen. Subjective symptoms caused by drusen were very rare. Changes in the appearance of the optic discs with drusen during the years could be documented in 15% of 153 patients. There were 5 patients with pigmentary retinopathy. The most usual of coincident disorders was migraine in 21 patients. The visual field findings are analysed in a companion report.
