ALTERATIONS IN THE FORM, MOVEMENT, AND STRUCTURE OF THE VITREOUS BODY IN APHAKIC EYES

Abstract

THE VITREOUS was studied with reference to its movements and attachments in phakic eyes and the results given in a previous paper.¹³ The present study includes observations of the form, movement, and structure of the vitreous made on 100 aphakic eyes after intracapsular cataract extraction, in seeking an explanation for certain postoperative complications. Sketches were made of the hyaloid membrane, its ruptures, and the relations of the vitreous to the iris in 67 eyes; the postrotational movements were studied and sketches made in 33 eyes. CHANGES FOUND The normal vitreous contains a fossa in its anterior surface, which accommodates the convex posterior surface of the lens. The vitreous hyaloid membrane in this fossa is normally attached to the surface of the lens at Eggers' line. This ring attachment serves to aid in imparting movements of the sclera to the vitreous. The convexity of the lens, too, aids in imparting
