The "capsular warning syndrome" (CWS) is characterized by recurrent stereotypical episodes of motor and/or sensory dysfunction without cortical signs. CWS is a clinically well recognized entity, and carries a significant risk of capsular infarct. The ischemia is most likely ascribable to hemodynamic changes in diseased small penetrating vessels. Treatment remains controversial and none has been...
PURPOSE OF REVIEW To review the methods described in the literature in the past year (from August 2003 to date). RECENT FINDINGS Techniques for scleral and iris suturing have proven safe and effective to fixate posterior chamber intraocular lenses and avoid the sight-threatening complications of anterior chamber lenses. SUMMARY Scleral and iris fixation have both become well-established eff...
Introduction Sustained, repetitive, prehensile activities that require precision and stability, necessitate a sustained static shoulder girdle posture over long periods of time, which can result in abnormal activation the musculature consequent scapular misalignments. Aim, Aim this study was to establish test-retest inter-tester reliability six (6) clinical tests commonly used measure parameter...
PURPOSE The lens epithelium can be separated into two regions, the nondividing central zone and the equator, the site of all division in the normal lens. In the present study, the distribution of epithelial growth factor (EGF)/epithelial growth factor receptor (EGFR) signaling components was investigated and related to mitotic distribution in the lens. METHODS Anterior and equatorial regions ...
Posterior capsulorhexis with optic capture was originally described by Gimbel and DeBroff [4] to maintain a clear visual axis after pediatric cataract surgery. This technique involves capturing the IOL optic through a primary posterior continuous curvilinear capsulorhexis (PCCC), while the haptics remain within the capsular bag (Figure 1). Studies have demonstrated this to be a valuable techniq...
Histological changes were studied in 34 senile cataractous lenses removed surgically from patients aged 50 to 78 years. Sixty-eight percent had nuclear sclerosis, 44% swollen cells and morgagnian globular changes, 23% calcium deposition, 15% migration of epithelial cells beneath posterior capsule and villous projection in posterior in 7%. Several cases had more than one histological abnormality...
PURPOSE To investigate mechanical properties of the human posterior lens capsule. METHODS Twenty-five human donor eyes were obtained from an eye bank. The age of the donors ranged from 1 to 94 years. Test specimens were prepared as tissue rings from posterior lens capsules by means of excimer laser. Capsular thickness was measured microscopically as the difference in focus between microspheru...
UNLABELLED We describe the use of the capsular anchor (AssiAnchor) to manage a subluxated intraocular lens (IOL) in the capsular bag. The anchor comprises 2 prongs that hold the anterior lens capsule and a central rod that is sutured to the scleral wall, enabling centration of the IOL-capsular bag complex. Six pseudophakic patients presenting with subluxated posterior chamber IOLs in the capsul...
OBJECTIVE To evaluate the influence of lung volume on dependent lung opacity seen at thin-section CT. MATERIALS AND METHODS In thirteen healthy volunteers, thin-section CT scans were performed at three levels (upper, mid, and lower portion of the lung) and at different lung volumes (10, 30, 50, and 100% vital capacity), using spirometric gated CT. Using a three-point scale, two radiologists d...
