Purpose.

Sinus Mucoceles are benign cystic cavities characterized by the presence of mucus-secreting epithelial cells which develops as a result of outflow obstruction of a sinus ostium. Orbital Mucoceles are conditions that can lead to severe ocular complications requiring urgent intervention. There are four types namely, FRONTAL SINUS MUCOCELE, MAXILLARY SINUS MUCOCELE, ETHMOID SINUS MUCOCELE and SPHENOID SINUS MUCOCELE. Orbital mucoceles Most commonly originate from the frontal and Ethmoidal sinuses and can spread through neighboring structures such as orbital walls. Frontal sinus mucoceles can displace the eye down, Ethmoid ones will push the eye out and maxillary lesions can elevate or push the eye in. Lastly, orbital mucoceles originating in the sphenoid sinus can compress the optic nerve resulting in loss of vision. The purpose of this poster is to create awareness of Optic Neuropathy associated with Orbital mucocele.

Case Report.

A 61-year-old Woman who is hypertensive with severe headaches noticed a rapid decrease in Visual Acuity in the left eye for 5months. Slit lamp and Ophthalmoscopic examinations revealed Proptosis, Relative Afferent Pupillary Defect and Optic Neuropathy in the left eye. Head CT scan Conducted revealed an orbital mass expanding parts of the left maxillary, left sphenoid and left ethmoid sinuses with thinning of the surrounding bone and compressing the optic nerve.

Conclusion.

Sphenoido-Ethmoido-Maxillary Mucocele can be associated with various detrimental effects, including retrobulbar optic neuropathy, cranial nerve palsies, and Acute visual loss. The severity of the optic neuropathy is affected by both the size and location of the mucocele, as well as the direction of its expansion. Sinus mucosa and dura mater stretching can induce trigeminal nerve-mediated periorbital pain.
