Retrospective analysis of translaminar, demographic, and physiologic parameters in relation to papilledema severity.

Objective: Some case reports suggest that the translaminar pressure difference is important in cases of papilledema. The purpose of this study was to determine ocular, physiologic, and demographic factors associated with papilledema severity.

Design: Retrospective, blinded study.

Functional anatomy and interaction of fast and slow visual pathways in macaque monkeys.

We measured the timing, areal distribution, and laminar profile of fast, wavelength-insensitive and slower, wavelength-sensitive responses in V1 and extrastriate areas, using laminar current-source density analysis in awake macaque monkeys. There were 3 main findings. 1) We confirmed previously reported significant ventral-dorsal stream latency lags at the level of V4 (V4 mean = 38.

Herpes zoster ophthalmicus: presenting as giant-cell arteritis.

A 74-year-old woman was referred to the authors' clinic with a 1-week suspicion of giant-cell arteritis. Uncomplicated, bilateral temporal artery biopsies were performed 3 days after admission for therapy. Four hours after the procedure she developed vesicular lesions of the face compatible with herpes zoster ophthalmicus.

Tonic pupil and sarcoidosis.

Purpose: To present a case of tonic pupil associated with enhancement in the region of the ciliary ganglion on magnetic resonance imaging in a patient with sarcoidosis.

Design: Observational case report.

Methods: A 52-year-old woman with sarcoidosis had a right pupil exhibiting sectoral palsy to light and light-near dissociation.
