Elschnig,² Grósz,³ Dunphy,⁴ Greenwood and Grossman,⁵ my brother, Sanford Gifford,⁶ and others, all expressed the belief that retrobulbar anesthesia reduced the percentage of cases of loss of vitreous in cataract extractions. In my study⁷ on loss of vitreous, I demonstrated that the extraocular muscles were capable of producing the massive losses that occur in about 10 per cent of cases of loss of vitreous.
