Early and Delayed Effect of Functional Endoscopic Sinus Surgery on Intraocular Pressure

Abstract Introduction Due to the close anatomical relationship between the paranasal sinuses and the orbit, involvement or injury of the orbit from paranasal sinuses procedures may occur. Objectives We aimed to study the early and delayed effect of endoscopic sinus surgery on intraocular pressure ( IOP ). Methods We included in the study 38 patients with chronic rhinosinusitis ( CRS), undergoing FESS. We performed FESS with the standard anterior to posterior approach. We measured IOP at the same time one day before surgery as well as day 1 and 6 weeks after surgery. Results One day aft...
