PURPOSE: We report an unusual case of severe proptosis during phacoemulsification in a 58-year-old female with a history of Crohn's disease, bilateral chronic panuveitis, prior bilateral central retinal vein occlusion, and uncontrolled steroid-associated ocular hypertension requiring bilateral Ahmed glaucoma drainage device (GDD) implantation with pars plana tube placement. OBSERVATIONS: During phacoemulsification of the right eye, the patient developed significant proptosis. Following lid speculum removal and mechanical eyelid manipulation, the proptosis resolved within 20 minutes without requiring a lateral canthotomy. The patient had no permanent visual complications. CONCLUSIONS AND IMPORTANCE: The likely pathophysiology of intraoperative proptosis in this case was accumulation of fluid in the retrobulbar space due to a functioning Ahmed tube shunt with the tube placed in the vitreous cavity. To avoid this complication, concurrent cataract surgery may be considered for patients with pars plana tube placement GDD surgery.
