Concomitant chorioretinal folds with disc edema can be seen in cases of thyroid eye disease presenting with compressive optic neuropathy and may portend optic nerve ischemia. We describe an unusual case of a 64-year-old man who developed partial vision loss after orbital decompression.

The source of this hemorrhage has been debated and may originate either from direct extension of intracranial hemorrhage or more likely from the peripapillary retinal vessels.
Observations: A 39-year-old woman presenting with nausea, vomiting, floaters and papilledema with normal neuroimaging was diagnosed ultimately with pseudotumor cerebri syndrome.

Purpose: To determine whether patients with Type B orbital blowout fractures (soft-tissue distortion disproportionate to bone-fragment displacement) repaired within 7 days of injury have statistically greater postoperative vertical binocular fusion than similar patients who undergo later surgery.
Methods: Prospective and retrospective surgical case series. Inclusion criteria were orbital floor (with or without medial wall) blowout fracture repair, preoperative coronal orbital CT scans, and patient age of at least 12 years at time of postoperative binocular visual field.
Cerebral venous sinus thrombosis (CVST) is a rare and potentially life-threatening cause of stroke. In the past few decades, the incidence and patient demographics have changed because of many factors, including the widespread use of oral contraceptives, improved detection of prothrombotic conditions, and advancement of imaging technology. The presentation of CVST is varied and can include ocular signs and symptoms.

A 73-year-old woman underwent routine enucleation for a blind, painful eye related to end-stage diabetic retinopathy and neovascular glaucoma. A large cystoid space, in continuity with the optic nerve stump, formed around the implant in the first few weeks following surgery. Aspirated contents were positive for β-2 transferrin, confirming cerebrospinal fluid origin.

Whether a catheter angiogram should still be obtained in cases with negative CTA or MRA remains debated and mostly relies on whether the noninvasive study was correctly performed and interpreted. The aim of our study was to review the diagnostic strategies used to evaluate patients with isolated aneurysmal third nerve palsy at a large academic center.

Design: Nonrandomized retrospective case series.
Participants: Thirty-seven consecutive cases of presumed trochlear nerve schwannoma from 9 tertiary university neuro-ophthalmology centers.
Objective: Protective properties of high-density lipoproteins (HDL) may include reverse cholesterol transport and suppression of oxidation and inflammation. These were investigated in vivo, as were the effects of HDL on the characteristics of atherosclerotic lesions.
Methods And Results: Male apolipoprotein E knockout (apoE-/-) and apoE-/- mice expressing human apolipoprotein AI (hAI/apoE-/-) were studied up to 20 weeks after commencing a high-fat diet.
Objective: To test the non-lipid-lowering effects of simvastatin on the response to injury in normolipidemic and hyperlipidemic mice.
Methods And Results: Wild-type (WT) mice (n = 40) and hyperlipidemic apolipoprotein-E-deficient (apoE(-/-)) mice (n = 40) received normal chow or chow containing simvastatin 100 mg/kg/day prior to bilateral femoral artery wire injury. Intimal hyperplasia and plasma cholesterol concentration were quantified after 4 weeks.
