Orbital varix thrombosis following surgical prone positioning for spinal decompression.

Orbital varix is a rare venous malformation within the orbit that is especially susceptible to thrombosis and hemorrhage. We report a unique case of vision-threatening orbital varix thrombosis resulting from prolonged prone positioning during an orthopedic spine procedure.

Lacrimal gland sparing IgG4-related disease in the orbit.

Purpose: We report an unusual case of orbital IgG4-related disease and discuss the distinguishing characteristics of the ophthalmic disease subtype.

Design: Case report.

Methods: Literature review and case description.
