Association between retinal layer thickness and postoperative delirium in older patients.

ABSTRACT:

Background

Postoperative delirium is one of the most common complications in the older surgical population, but its pathogenesis and biomarkers are largely undetermined. Retinal layer thickness has been demonstrated to be associated with cognitive function in mild cognitive impairment and patients with Alzheimer's disease. However, relatively little is known about possible retinal layer thickness among patients with postoperative delirium.

Aims

We aimed to investigate the relationship between retinal layer thickness and postoperative delirium in this cross-sectional study.

Methods

The participants (≥65 years old) having elective surgery under general anaesthesia were screened via medical records from Shanghai 10th People's Hospital. Preoperative macular thickness and
