title: Polaroid photomacrography using the SX-70 camera.
abstract: This paper describes a technique for taking color photographs of the external eye using the Polaroid SX-70 camera and a biomicroscope. It is particularly useful in providing a photographic record of anomalies such as pterygium, in which the rate of progression across the cornea can be observed over a period of months or years.
