Metastatic Renal Cell Carcinoma Masquerading as a Sphenoid Wing Meningioma.

A 47-year-old man who presented with subacute binocular diplopia and a left head turn was found to have a right sixth nerve palsy and right optic disc edema. Radiologic imaging revealed a non-lytic right greater sphenoid wing mass with a dural tail, suggestive of a sphenoid wing meningioma. The patient underwent an orbitotomy with lesion biopsy; histopathologic analysis and subsequent imaging revealed the diagnosis of metastatic clear cell renal cell carcinoma.

Visual Outcomes of Patients With Retrobulbar Hemorrhage Undergoing Lateral Canthotomy and Cantholysis.

Purpose: Evaluate visual outcomes in relation to time from injury to intervention in patients who undergo lateral canthotomy with cantholysis (LCC) for retrobulbar hemorrhage (RBH).

Methods: Retrospective study of patients with orbital compartment syndrome (OCS) secondary to RBH who underwent LCC. OCS due to RBH was defined by a combination of decreased vision, proptosis, resistance to retropulsion, increased intraocular pressure, and relative afferent pupillary defect.

Repositioning a posteriorly dislocated silicone plate-haptic toric intraocular lens.

We describe a technique for repositioning an encapsulated, posteriorly dislocated silicone plate-haptic toric intraocular lens (IOL) while preventing further dislocation into the vitreous cavity. Sutures of 10-0 polypropylene were used to ensure safe retrieval of the dislocated IOL. An anterior vitrectomy was then performed to remove the contracted capsular bag around the IOL.

Reducing synuclein accumulation improves neuronal survival after spinal cord injury.

Spinal cord injury causes neuronal death, limiting subsequent regeneration and recovery. Thus, there is a need to develop strategies for improving neuronal survival after injury. Relative to our understanding of axon regeneration, comparatively little is known about the mechanisms that promote the survival of damaged neurons.

Propranolol and Mesenchymal Stromal Cells Combine to Treat Traumatic Brain Injury.

Unlabelled: More than 6.5 million patients are burdened by the physical, cognitive, and psychosocial deficits associated with traumatic brain injury (TBI) in the U.S.
