PHOTOGRAPHY OF CORNEAL PATTERN

PHOTOGRAPHY OF CORNEAL PATTERN Abstract To the Editor. —I read with great interest Dr. Schweitzer's communication in the April 1967 issue of the Archives (77:548), dealing with the polygonal pattern of the cornea. I have been photographing the same pattern for over a year (Pentax Spotmatic camera loaded with Agfa Isopan Record Film). With appropriate excitor and barrier filters before the flash and camera, the fluorescent pattern is readily recorded.There are a number of ways of inducing or observing the pattern. For instance, if a glass slide is pressed against the cornea in the presence of fluorescein, a mosaic of dark lines against a fluorescent background may be seen. On removing the glass slide and allowing the subject to blink, the lines take up fluorescein and the polygons become fluorescein-free. The pattern then is identical to that induced by simple massage of the cornea through the lid.In the absence of fluorescein, the References 1.

Abstract

Abstract To the Editor. —I read with great interest Dr. Schweitzer's communication in the April 1967 issue of the Archives (77:548), dealing with the polygonal pattern of the cornea. I have been photographing the same pattern for over a year (Pentax Spotmatic camera loaded with Agfa Isopan Record Film). With appropriate excitor and barrier filters before the flash and camera, the fluorescent pattern is readily recorded.There are a number of ways of inducing or observing the pattern. For instance, if a glass slide is pressed against the cornea in the presence of fluorescein, a mosaic of dark lines against a fluorescent background may be seen. On removing the glass slide and allowing the subject to blink, the lines take up fluorescein and the polygons become fluorescein-free. The pattern then is identical to that induced by simple massage of the cornea through the lid.In the absence of fluorescein, the References 1.
