Claim One:
1. A method of eye examination for detecting structural anomaly in the retina, comprising the steps of: A. with the retina in a first stress condition, illuminating the retinal surface with coherent light; B. with the retina in the first stress condition, forming a record of a first exposure on a photosensitive medium of coherent light reflected from said retinal surface; C. allowing the stress condition of the retina to change by an incremental amount to create a second stress condition; D. with the retina in said second stress condition, forming a record of a second exposure on said photosensitive medium of coherent light reflected from said retinal surface, the reflected light recorded on the photosensitive medium during steps B and D being focused in such a way as to provide a pair of images corresponding to the retinal surface that are slightly displaced and mutually overlapping on the photosensitive medium; E. using the records of said first and second exposures to form an interference pattern on said photosensitive medium as a function of the change in said retinal surface corresponding to said first and second exposures; and F. analyzing said interference pattern for the presence or absence of anomalous fringes characteristic of retinal anomaly.
