Twenty-six ankles of 23 patients with seropositive or negative arthritis and 24 ankles of 12 cadavers as a control group were studied by contrast synoviography. The main features in the patients were capsule enlargement, hypertrophic synovitis, and connections to tendon sheaths and to the posterior subtalar joint. None of the controls showed capsule distension or irregular outline of the joint ...

The cause of dislocation of an intraocular lens is a direct blow or jerk, and dislocation may complicate both iris-supported and capsule-supported lenses. In capsule-supported lenses the implant dislocates towards the anterior chamber but in iris-supported lenses the dislocation is posterior. A technique for removal of a posterity dislocated lens is described.

Although often clinically indistinguishable in the early stages, Parkinson's disease (PD), Multiple System Atrophy (MSA) and Progressive Supranuclear Palsy (PSP) have distinct neuropathological changes. The aim of the current study was to identify white matter tract neurodegeneration characteristic of each of the three syndromes. Tract-based spatial statistics (TBSS) was used to perform a whole...

INTRODUCTION Posterior capsule rupture causes instant vitreous contamination, resulting in endophthalmitis. However, transfer of intracameral moxifloxacin (MFLX) to the vitreous has not been examined in detail. We investigated vitreous antibiotic concentrations following intracameral MFLX in both ruptured and intact posterior capsular eyes. METHODS Experiment 1: Intraocular lenses were insert...

PURPOSE To investigate the ability of an open capsule device to prevent posterior capsule opacification. METHODS A total of 40 eyes of 20 New Zealand white rabbits were randomly divided into six similar groups of 6 to 7 eyes each. After crystalline lens evacuation, one control group (group A) was implanted with a hydrophilic acrylic intraocular lens and no device, and another control group (g...

The functional anatomy of motor recovery was studied by assessing motor function quantitatively in 23 patients following capsular or striatocapsular stroke. While selective basal ganglia lesions (caudate and/or putamen exclusively) did not affect voluntary movements of the extremities, lesions of the anterior (plus caudate/putamen) or posterior limb of the internal capsule led to an initially s...

We compared the age-related morphology of the cricothyroid (CT) joint with that of the cricoarytenoid (CA) joint using 18 specimens from elderly cadavers in terms of their elastic fiber contents as well as the cells composing the joint capsule and synovial tissues. In contrast to an almost flat-flat interface in the CT joint, the CA joint was similar to a saddle joint. The CA joint capsule was ...

PURPOSE To determine whether apoptosis or necrosis of lens epithelial cells occurs after lens extraction. METHODS Lens extraction was performed on 24 rabbit eyes. The authors then performed terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling (TUNEL) and transmission electron microscopy on the eyes 1 to 10 days after surgery. RESULTS The postoperative lens was demarcated in...

The internal capsule conveys information from primary and supplementary motor areas, frontopontine and thalamic peduncles to brain stem and cerebellar regions, and from thalamus to prefrontal cortex. Neurological accidents involving the internal capsule indicate differential functional correlates with its sectors. To examine the microstructural condition of this fiber system and to test functio...

AIMS To determine whether alpha smooth muscle actin (alpha-SMA), a marker for myofibroblastic cells, is present in lens epithelial cells (LECs) in rabbit aphakic eyes. METHODS Phacoemulsification was performed in rabbit eyes, which were enucleated after surgery. Immunohistochemical methods were used to detect alpha-SMA in LECs. RESULTS Five days after surgery, the presence of alpha-SMA posi...
