Abstract:

The techniques described were developed to corroborate the feasibility of making in vivo measurements of image parameters in the interior of the eye. The preliminary experiments on excised eyes demonstrated that the procedure for photographing the image was a reliable and valid way to record the image for detailed examination. The design of a suitable fiber optics conduit posed several difficult problems. However, it was demonstrated that the design achieved does provide a means for transmitting the information directly to an external detector and that the resolution of the system can be made sufficiently high to provide the required fidelity. The results of the in vitro experiments with excised eyes indicate that 20 micron diameter at intensity value of 1e of maximum is probably the limiting size one can expect to find for an emetropic, light adapted rhesus monkey eye. The in vivo measurements derived from a limited number of samples resulted in values of 32 microns for a 2mm pupil and 37 microns for a 4mm pupil. Author
