We studied 13 patients, six males and seven females, ranging in age from 14 to 53 years, with chronic pars planitis and a form of secondary retinal degeneration. All had experienced visual blurring but none had significant pain. Nine of the 13 had some disturbance in night vision. Visual acuity had decreased in three patients (in one because of cataract, in one because of cystoid macular degeneration, and for unknown reasons in the third), increased in two patients (because of improvement in cystoid macular edema), and remained stable in eight. There were electrophysiologic abnormalities, consisting of delayed B-wave implicit time, abnormal response to 30-Hz flicker, and reduced B-wave oscillations, in almost every patient. Our finding suggested that pars planitis is a vitreoretinal disorder rather than an inflammatory disease of the uveal tract.
我们研究了13例患者，其中6例男性，7例女性，年龄在14至53岁之间，患有慢性睫状体平坦部炎和一种继发性视网膜变性。所有患者均有视力模糊，但均无明显疼痛。13例中有9例存在夜视力障碍。3例患者视力下降（1例因白内障，1例因黄斑囊样变性，第3例原因不明），2例患者视力提高（因黄斑囊样水肿改善），8例患者视力保持稳定。几乎每位患者都存在电生理异常，包括B波潜伏时间延迟、对30Hz闪烁光的异常反应以及B波振荡减弱。我们的研究结果表明，睫状体平坦部炎是一种玻璃体视网膜疾病，而非葡萄膜的炎症性疾病。
