    To study the outcome of patients with orbital apex lesions treated with endoscopic decompression alone.Retrospective medical chart review with a mean follow-up of 25.6 months.Departments of Ophthalmology and Otolaryngology, University of Washington, Seattle.Five individuals seen at the University of Washington Medical Center from November 2003 through December 2005 with visual disturbance caused by orbital apex lesions as documented by preoperative magnetic resonance imaging or computed tomographic scan.All patients underwent endoscopic decompression of the medial wall of the orbital apex with incision of the periorbita.Postoperative visual acuity, presence or absence of a relative afferent pupillary defect, color vision, and visual field were recorded.All 5 patients presented with visual field deficits, 4 of whom improved postoperatively. Three patients had dyschromatopsia preoperatively, 2 of whom improved postoperatively. Visual acuity improved or stabilized in 4 of 5 patients postoperatively. One patient had progressive visual loss during the course of her follow-up, which, after obtaining postoperative imaging, was attributed to inadequate decompression of the apex at its most posterior aspect. This same patient also developed postoperative sinusitis that resolved with antibiotic treatment. Two patients developed diplopia, 1 in primary gaze requiring treatment with prismatic lenses. All patients presented with and maintained normal intraocular pressures.Orbital apex lesions can often be effectively and relatively safely treated by endoscopic decompression alone.
