Ninety-nine (11.6%) of 850 phakic retinal detachment patients had bilateral detachments. The incidence of bilaterality was greater in nontraumatic detachments (13.4%) than traumatic detachments (3.8%). Patients were divided into two refractive classes: (1) myopic, containing refractive errors of -2.50 diopters or more, and (2) nonmyopic, containing all other refractive errors. The rate of bilaterality in nontraumatic detachments varied with refractive class and lattice degeneration: nonmyopic without lattice (8.1%), nonmyopic with lattice (14.2%), myopic without lattice (16.3%), and myopic with lattice (24.6%). Mean age in years at onset of the initial detachment varied with refractive class and lattice degeneration: nonmyopic without lattice (59.1), nonmyopic with lattice (55.8), myopic without lattice (49.2), and myopic with lattice (28.2). Lattice degeneration reduced the interval between detachments. Annual risks of fellow eye detachments were calculated for four groups: nonmyopic without lattice (0.12%), nonmyopic with lattice (0.95%), myopic without lattice (1.3%), and myopic with lattice (0.98%).
850例有晶状体眼视网膜脱离患者中，99例（11.6%）为双侧脱离。非创伤性脱离的双侧发生率（13.4%）高于创伤性脱离（3.8%）。患者被分为两个屈光类别：（1）近视，包括屈光度为-2.50或更高的屈光不正；（2）非近视，包括所有其他屈光不正。非创伤性脱离的双侧发生率因屈光类别和格子样变性而异：无格子样变性的非近视患者（8.1%）、有格子样变性的非近视患者（14.2%）、无格子样变性的近视患者（16.3%）、有格子样变性的近视患者（24.6%）。初次脱离发病时的平均年龄因屈光类别和格子样变性而异：无格子样变性的非近视患者（59.1岁）、有格子样变性的非近视患者（55.8岁）、无格子样变性的近视患者（49.2岁）、有格子样变性的近视患者（28.2岁）。格子样变性缩短了两次脱离之间的间隔时间。计算了四组患者健眼每年发生视网膜脱离的风险：无格子样变性的非近视患者（0.12%）、有格子样变性的非近视患者（0.95%）、无格子样变性的近视患者（1.3%）、有格子样变性的近视患者（0.98%）。
