Central retinal artery occlusion with subsequent central retinal vein occlusion in the same eye is a rare entity. We present a 72-year-old man with biopsy-proven giant cell arteritis who developed bilateral arteritic anterior ischemic optic neuropathy and a left central retinal artery occlusion. Subsequently, he developed a left central retinal vein occlusion within 2 weeks of his initial vision loss. His vision did not improve with corticosteroids.

To our knowledge, there are no studies of patients with idiopathic intracranial hypertension (IIH) that address the relationship between level of intracranial pressure (ICP) and likelihood of progressive visual loss despite uncomplicated optic nerve sheath decompression (ONSD). This study investigated whether patients with IIH undergoing ONSD had a higher risk of surgical failure if opening pressure (OP) on lumbar puncture was ≥50 cm H2O compared to those with OP <50 cm H2O. ⋯ Patients with IIH and an OP ≥50 cm H2O had a 3-fold increased risk of failure of ONSD to prevent progressive visual loss, requiring a shunting procedure when compared to those with OP <50 cm H2O. Visual acuity at presentation and male sex also were associated with progressive visual decline after ONSD. These risk factors merit closer follow-up in the postoperative period when signs of further visual deterioration would indicate an urgent need for neurosurgical shunting.
