Orbital apex syndrome (OAS) is a rare and serious condition that can affect vision and potentially be life-threatening due to its links to sinus infections.
A study reviewed 27 patients who had OAS caused by sinusitis and underwent endoscopic sinus surgery (ESS) from 2011 to 2021, focusing on symptom resolution and outcomes.
Results showed that while some patients experienced stabilization or improvement in vision post-surgery, there were significant reductions in ptosis (70% improvement) and ophthalmoplegia (85% improvement), with minimal complications and a low mortality rate of 3.7%.
