Angle-closure glaucoma in association with orbital pseudotumor
Bernardino CR; Davidson RS; Maus M; Spaeth GLOphthalmology 2001; 108: 1603-1606
PURPOSE: To describe the pathophysiology of angle-closure glaucoma secondary to idiopathic inflammatory orbital pseudotumor. DESIGN: Retrospective, small noncomparative case series. PARTICIPANTS: Three patients with angle-closure glaucoma and orbital pseudotumor. METHODS: The pathophysiology of this entity was investigated using magnetic resonant imaging (MRI) and ultrasound biomicroscopy (UBM). MAIN OUTCOME MEASURES: Clinical features, anterior chamber angle configuration, and intraocular pressure. RESULTS: Angle closure from anterior rotation of the ciliary body caused by choroidal effusions secondary to pseudotumor was demonstrated using MRI and UBM. Two of the three cases resolved after treatment for orbital pseudotumor. CONCLUSIONS: Idiopathic orbital pseudotumor is a cause of secondary angle-closure glaucoma. The mechanism of angle closure is anterior rotation of the ciliary body secondary to choroidal effusions resulting from the orbital inflammation.
