The corneal stroma is a connective tissue which combines the usual properties of strength and resilience with one property, transparency, unusual in such tissues. Several models have been put forward to account for this transparency, these differ in detail but in almost all cases the regularity of arrangement of the collagen fibrils is taken to be an important parameter of the model (Maurice, 1957; Farrell & Hart, 1969; Benedek, 1971). So far the only experimental evidence about this arrangement comes from electron microscopy, and we have therefore applied small‐angle diffraction techniques because they involve less preparative procedures which might cause artifacts.
