Abstract:
We report the case of a 35-year-old man with no relevant past medical history who was referred for intermittent left-sided proptosis, self-limited blurred vision, and unilateral ocular hypertension. Examination showed preserved extraocular motility, mild left proptosis, and intraocular pressure of 19mmHg in the right eye and up to 29mmHg in the left eye, without structural glaucomatous damage on optical coherence tomography. Computed tomography demonstrated a large left frontal mucocele with remodeling and bony dehiscence of the orbital roof, causing extraconal mass effect on the left orbit. Topical hypotensive therapy was initiated, followed by endoscopic sinonasal surgery with left Draf IIb and right Draf I frontal sinusotomy technique. After surgery, proptosis resolved and intraocular pressure decreased to 14mmHg in the left eye. This case highlights frontal mucocele with orbital extension as an uncommon and potentially reversible cause of unilateral ocular hypertension.
