Retinal detachment sometimes extends beyond the retina proper, through the region of the ora serrata to involve the pars plana ciliaris. This clinical feature has previously been reported by Schepens (1950,5 19574) in relation to retinal detachment, and by Grignolo, Schepens, and Heath (19571) in relation to cysts of the pars plana ciliaris. An extension of these cysts posteriorly may cause detachment of the ora serrata; however, this mechanism did not appear significant in the cases reported here. Klien (19412) and Samuels and Fuchs (19523) have reported a series of pathological specimens with detachment of the pars ciliaris retinae, but all of Klien's cases were associated with intraocular neoplasm or severe injury. This communication concerns the clinical features, incidence, and distribution of detachment of the ora serrata and epithelium of the pars plana ciliaris in cases of "idiopathic" retinal detachment.
