Incidence and risk factors of postoperative visual function impairment in elderly patients undergoing nonocular surgery: a prospective cohort study

Comprehensive perioperative eye protection

“…The present edition of BJAN has articles related to the topic. One of the articles assessed perioperative visual acuity and IOP of patients submitted to major non-cardiac surgeries, 7 and another assessed patients submitted to heart surgery with and without cardiopulmonary bypass. 8 Two other observational studies 9 , 10 assessed the effect of the head-down tilt position during robotic prostatectomy on IOP, in that one of the studies correlated IOP with the optic nerve sheath diameter.…”

“…In this edition of BJAN, Badessa et al 7 performed a prospective observational study that included visual acuity and IOP assessment in the pre- and postoperative periods of elderly patients submitted to long major non-ophthalmological surgeries to assess the incidence and risk factors for postoperative visual changes. Among the 107 elderly patients assessed, 21 presented visual function impairment on the third postoperative (PO) day, and of those, 33% on the 21 st PO, totaling 6.5% of total patients assessed.…”
