Heidelberg Perimeter with 90 degree rotating arm 1883

Heidelberg perimeter with 90 degree rotating arm from around 1883. Ophthalmic surgeon, Malcolm MacDonald McHardy (1852-1913),published the first perimeter with a quarter arc in 1882.

The Jung company produced the Heidelberg perimeter which looked like the one shown here. This is a modification of the Priestley Smith perimeter.

The perimeter was a huge breakthrough in examining and recording a patient’s peripheral vision. It allows the eye doctor to follow the success or failure of treatment of diseases such as chronic open angle glaucoma.
