Sixteen patients enrolled in the PERK study were evaluated by fluorophotometry 24 hours or six months following radial keratotomy. A comparison of eyes operated and not operated upon showed that endothelial permeability was not significantly altered 24 hours and six months after surgery. Aqueous humour flow rates and anterior chamber elimination coefficients were significantly higher 24 hours after surgery in the eyes operated on than in those not operated on. Six months after surgery there was no longer a significant difference in these factors. The increase in aqueous humour flow rates 24 hours after surgery may represent a subclinical breakdown in the blood-aqueous barrier.
16名参加PERK研究的患者在接受放射状角膜切开术后24小时或6个月时接受了荧光光度法评估。对手术眼和未手术眼的比较显示，术后24小时和6个月时内皮通透性没有明显改变。手术眼术后24小时的房水流量和前房清除系数显著高于未手术眼。术后6个月，这些因素不再有显著差异。术后24小时房水流量的增加可能代表血-房水屏障的亚临床破坏。
