[The involutional vitreoretinal syndrome].

Ocular changes in elderly subjects are described, that may be regarded as manifestations of a disease, denoted by the author as the involution vitreoretinal syndrome. The subjective signs of the syndrome are floating 'moths', photopsias presenting as a 'lateral lightning', sudden appearance of a central macula (central positive scotoma). The objective signs are destruction and posterior detachment of the vitreous body, peripheral retinal dystrophy, stable light reflexes (coin-shaped, flap, etc.) on the fundus oculi, previously described by the author. The syndrome complications are fibroplasia of the fundus oculi central area, macular edema, perforation of the macula and characteristic lenticular changes. The author singled out the cases with combined changes of the vitreous body, fundus oculi and lens involvement as a lentivitreoretinal form of the involution vitreoretinal syndrome.
