RESUMO
In a retrospective study of 1180 consecutive eyes operated for retinal detachment, vitreous traction on the rent was the determining factor for the development of proliferative vitreoretinopathy (PVR). Round, multiple, small holes in equatorial degeneration (retinogenic) and macular holes in which no vitreous traction on the rent was found did not complicate with PVR. Retinal detachment caused by horseshoe or crescent-shaped tears with evidence of vitreous traction (vitreogenic) developed PVR to a variable degree: in 171 (25.8%) senile myopic, 19 (44.2%) senile-myopic aphakic, 23 (20.2%) typical aphakic, and 32 (78.1%) patients with giant tears. We also found that retinogenic retinal detachments affected younger age groups more than did vitreogenic retinal detachments.

Of 471 retinal detachments occurring in aphakic patients after undergoing intracapsular cataract extraction, we reviewed 318 eyes with uncomplicated aphakia (no vitreous loss). Myopic eyes had equatorial breaks 38% of the time versus 19% for nonmyopic eyes. The time interval between aphakia and detachment was shorter for myopic than for nonmyopic eyes. Our results showed a significant incidence of: (1) equatorial breaks in myopic eyes versus nonmyopic eyes (P less than 0.005), and (2) earlier detachments for myopic eyes versus nonmyopic eyes (P less than 0.005). The presence of equatorial breaks seemed to be associated with earlier retinal detachments.
