In this case report, it is reminded that intraocular infectious or inflammatory invasive lesions may cause sudden onset diplopia.


A 60-year-old male patient applied to our clinic with the complaints of edema, diplopia and pain around the right eye. In the examination of the patient, visual acuity of both eyes was 20/20, anterior segment biomicroscopic findings, fundus examination were found to be normal in both eyes. There was no reactive afferent pupillary defect. It was determined that the patient had mild proptosis and dystopia, limited movement in the right eye and diplopia endorsed when the patient looked up.
CT was taken to evaluate the patient’s orbit. Soft tissue-fluid densities were observed in the right frontal sinus, which destroyed the bone structure inferiorly and extended superiorly to the orbit. In the MRI, mucocele with hemorrhagic and cystic component was detected extending into the right frontal sinus, anterior ethmoid cell, middle meatus and periortibal adipose tissue, and a defect at supraorbital level, extension of the mass to this area, compression in the rectus superior muscle periorbital fat tissue detected.


The patient was taken to surgery,Functional Endoscopic Sinus Surgery procedure was started.There was a dense osseous tissue at the level of ethmoid sinuses blocking the passage to the frontal sinus ostium, that was apparent in the preoperative paranasal sinus.Then we moved on with the external approach to the frontal sinus through an incision at the lower border of the right eyebrow. An opening of about 2cm of diameter was made with chisels by preparing an osteoplastic flap that allowed the exposure of the frontal sinus. Just after the entrance of the sinus a copious amount of thick purulent discharge was observed and it was completely aspirated.


The mucocele rapidly eroded the upper orbital wall, preventing eye movements and causing dystopia due to pressure on the upper rectus muscle and globe. Both surgical procedures should be performed before orbital and cranial complications develop.External sinus surgery may be required in addition to endoscopic interventions.
