Neither topical nor retrobulbar anesthesia affected POCD in this small geriatric cohort; leaves open need for larger randomized trials.
Postoperative cognitive dysfunction (POCD) has become a major concern for anesthesiologists and surgeons, particularly in elderly who already have limited cognitive status. General anesthesia is a well known risk factor for this entity. However, there is insufficient data regarding the association between regional anesthesia and POCD. This study aimed to investigate the impact of different regional anesthesia techniques on the development of POCD in elderly patients undergoing cataract surgery. Methods: The patients above 65 years who underwent cataract surgery were enrolled in this study. All patients were assigned to one of two anesthesia groups; topical anesthesia group (n=16) and retrobulbar blockade group (n=25). Cognitive status was assessed preoperatively and postoperatively (1st hour, 1st day, and 1st week), using Blessed Orientation-Memory-Concentration (BOMC) test.

Kılıç et al. (2021) conducted a cohort in Cataract (n=41). Retrobulbar blockade vs. Topical anesthesia was evaluated on Blessed Orientation-Memory-Concentration (BOMC) score at 1st week (p=0.435). Retrobulbar blockade compared to topical anesthesia had no significant effect on the development of postoperative cognitive dysfunction in geriatric patients undergoing cataract surgery.
