Mucoceles are epithelial-lined cavities filled with sterile mucus that develop due to the obstruction of a sinus ostium. Frontal mucocele is one of the most common among mucoceles. Most of them present with ophthalmic manifestations. Here, we present such a case with ocular symptoms. Despite the absence of thyroid-related symptoms or significant medical history, her examination revealed left eye proptosis, limited ocular motility, optic disc edema, and significant visual loss due to optic nerve compression. Further investigations, including orbital computed tomography, confirmed a frontal mucocele extending into the left orbit. Following endoscopic sinus surgery with mucocele excision, the patient experienced significant improvement in vision, resolution of optic disc edema, and proptosis. This case underscores the importance of considering mucoceles in the differential diagnosis of orbital pathologies. It also highlights the efficacy of endoscopic management in achieving favorable outcomes and emphasizes the significance of interdisciplinary collaboration in optimizing patient care.
