Schweigger's Perimeter

Schweigger's Perimeter

Usage conditions apply
A perimeter is used to examine the retina. Karl Ernst Theodor Schweigger (1830-1905), a German ophthalmologist, introduced a hand-held model in 1889. An inscription on this example reads "CH STOELTING CO / CHICAGO ILL." According to Stoelting, this form was used by “the United States Surgeon General’s office and in many of the Psychological Laboratories of educational institutions for experimental work.”
