Conjunctival fluid pH was measured pre- and post-operatively in 16 patients suffering from senile cataract. We found a significant increase (P less than 0.05) from 7.26 +/- 0.23 (mean +/- SD) on the day before operation to 7.50 +/- 0.23 (mean +/- SD) on the first post-operative day in the conjunctival fluid of the treated eye. Thereafter a gradual decrease towards pre-operative level was observed. These changes were not observed in the healthy fellow eye (P greater than 0.05). No significant pre-operative difference was shown between the two eyes. It is reasonable to assume that the composition of the transudate/exudate from the conjunctival vessels might be responsible for the changes observed.
对16例老年性白内障患者在手术前后测量结膜液pH值。我们发现，患眼结膜液pH值从手术前一天的7.26±0.23（均值±标准差）显著升高（P<0.05）至术后第一天的7.50±0.23（均值±标准差）。此后，观察到其逐渐降至术前水平。在健康的对侧眼未观察到这些变化（P>0.05）。两眼术前无显著差异。可以合理推测，结膜血管渗出液/漏出液的成分可能是观察到的这些变化的原因。
