The types and locations of retinal tears associated with 268 pseudophakic retinal detachments were studied as a function of the time at which they occurred following cataract surgery. Retinal detachments occurring more than two years following cataract extraction were significantly more likely to have their most posterior retinal break located at the posterior margin of the vitreous base than at or behind the equator. This distribution of tears was not observed in detachments occurring within six months of cataract surgery, with equatorial tears being significantly more common in early onset detachments than in those occurring after two years. The anterior tears which cause most retinal detachments long after cataract extraction are due to persistent chronic traction upon the vitreous base rather than to acute posterior vitreous detachment.
