title: A clinical analysis of pseudopapilledema. I. Population, laterality, acuity, refractive error, ophthalmoscopic characteristics, and coincident disease.
abstract: To clarify clinical features of pseudopapilledema, 142 cases (250 eyes) were analyzed regarding sex, age, race, bilaterality, acuity, refractive error, fundus characteristics, and coincident disease. Ninety-eight cases of identifiable hyaline bodies ([HB] group 1) were compared with 44 cases of pseudopapilledema without HB (group 2). The following results were notable: marked predominance of whites; one third in group 1 were unilateral, and 14% of all pseudopapilledema was unilateral; in only one eye did HB apparently account for diminished acuity; refractive error distribution paralleled that in the general population; anomalous vascular patterns occurred in 20% of group 1 and in 31% of group 2; pigment epithelial changes were found in 33% of group 1 and in 20% of group 2; and a statistically significant association was found with retinitis pigmentosa only. Analysis of field defects is the subject of a companion report.
