[Cognitive function of geriatric ophthalmology patients after local and general anesthesia].

Since there will be an increase in the number of geriatric patients who undergo surgery and anesthesia over the next few years, studies comparing the effects of general and local anesthesia on cognitive functioning in elderly persons are mandatory. One hundred eleven ophthalmological patients, all over the age of 64 years, were assessed preoperatively, on the first and on the fourth postoperative day using a battery of standardized cognitive tests. Of the initial sample, 47 patients undergoing local and 54 undergoing general anesthesia completed the assessment.
