Occasionally, patients who underwent surgery for complicated retinal detachment report spatial distortions. This may be due to a translocation of photoreceptors when they become reattached to the pigment epithelium. We wanted to find out if, and to what extent, similar translocations occur after a simple buckling operation.
Binocular retinal correspondence was used as an indicator of photoreceptor translocation. Correspondence was measured in the peripheral visual field at eccentricities of 5, 10 and 20 degrees, using a mirror haploscope. We examined two normal observers, one patient having had surgery for complicated retinal detachment including retinotomy, and 23 patients who had simple radial buckling operations.
The patient who had received complicated detachment surgery including retinotomy revealed a tremendous shift in correspondence. Of the 23 patients who had simple radial buckle operations, only 10 were able to sustain central fixation while being tested in the periphery. Of these 10 patients, 2 showed distortions of peripheral retinal correspondence in the area of previous retinal detachment. However, only one of them remembered some spatial distortion after surgery.
As a rule, photoreceptors become correctly reattached after radial buckle operations for retinal detachment. Rarely, vertical or horizontal translocations of about 1 to 2 degrees occur, but this does not usually lead to metamorphopsia.
偶尔，接受复杂性视网膜脱离手术的患者会报告空间扭曲。这可能是由于光感受器重新附着于色素上皮时发生了移位。我们想弄清楚在简单的巩膜扣带术后是否会发生类似的移位，以及移位的程度如何。
双眼视网膜对应关系被用作光感受器移位的指标。使用镜面检眼镜在周边视野5度、10度和20度的偏心度下测量对应关系。我们检查了两名正常观察者、一名接受过包括视网膜切开术在内的复杂性视网膜脱离手术的患者以及23名接受简单放射状巩膜扣带手术的患者。
接受过包括视网膜切开术在内的复杂性脱离手术的患者显示出对应关系的巨大偏移。在23名接受简单放射状巩膜扣带手术的患者中，只有10名在周边视野检查时能够维持中心注视。在这10名患者中，2名在先前视网膜脱离区域出现周边视网膜对应关系的扭曲。然而，其中只有1人记得术后有一些空间扭曲。
通常，视网膜脱离的放射状巩膜扣带术后光感受器会正确重新附着。很少会发生约1至2度的垂直或水平移位，但这通常不会导致视物变形。
