Abstract To the Editor. —In the July 1990 issue of the Archives, an interesting article appeared on a posterior precortical vitreous pocket (PPVP).1 The article describes an intravitreal, premacularly located structure that, in the authors' words, "seemed to be analogous to the bursa premacularis." I discovered the bursa premacularis2,3 in 1970. According to the authors, important differences exist between the bursa premacularis and the PPVP: the PPVP is not a sack; the PPVP is lined by the posterior hyaloid membrane posteriorly, but the anterior extent is delineated by the vitreous gel; and the bursa is not necessarily confined to the macula.See also pp 1059 and 1060.Therefore, the authors deemed it necessary to give this structure a new name.In their article, the authors have confirmed the existence of a premacularly located intravitreal space, that in their—and my—opinion has important implications for macular function and pathologic changes.
