Abstract

Anastasios Lavaris, Tryfon Rotsos and Marilita M Moschos

Background: Purpose of this case report is to describe, for the first time in literature assessed by optical coherence tomography (OCT) and visual evoked potentials (VEP), a rare case of partially reversible unilateral vision loss accompanied by retrobulbar optic neuritis symptomatology, after nasal polyps removal using endoscopic sinus surgery (ESS) technique. Case presentation: A 41-year old Greek male developed unilateral vision loss, partially reversible within 72 hours, reduced color vision, superior scotoma and retrobulbar pain on eye movement immediately after recovering from nasal polyp removal with (ESS) technique. He underwent complete ophthalmological examination including optical coherence tomography, fluorescein angiography, visual fields and visual evoked potentials. A magnetic resonance imaging (MRI), neurological examination and laboratory evaluation were also performed revealing no abnormalities. Conclusions: Sinus surgeons and ophthalmologists should be familiar with the possibility of irreversible visual impairment after endoscopic sinus surgery and enhance collaboration for facilitating better recognition and early treatment.
