为了确定使用室温冲洗液进行眼内冷却是否会导致视网膜电图读数异常，我们对6名黄斑前纤维化和轻微视网膜脱离患者进行了手术，测量玻璃体腔内的温度并使用视网膜电图监测器。玻璃体切除术后，玻璃体腔内的温度降至27 ℃至28 ℃，在此期间使用室温溶液。这导致异常的视网膜电图读数（明显延迟的峰值时间和降低的振幅）。这些结果表明，常规使用的室温溶液会影响玻璃体切除术期间的视网膜功能;然而，这种功能变化在只有轻微视网膜异常的患者中是可逆的。
To determine whether intraocular cooling using room-temperature irrigating solution can cause abnormal electroretinograph readings, we operated on six patients with premacular fibrosis and minimal retinal detachment, measuring the temperature in the vitreous cavity and using an electroretinographic monitor. The temperature in the vitreous cavity dropped to 27-degrees-C to 28-degrees-C after vitrectomies during which room-temperature solutions were used. This resulted in abnormal electroretinograph readings (markedly delayed peak times and reduced amplitudes). These results suggest that the routinely used room-temperature solution affects retinal function during vitrectomy; however, this functional change was reversible in patients having only minimal retinal abnormality.
