PURPOSE To determine the relationship between changes in contrast sensitivity, if any, after glaucoma therapy and the test-retest reliability of the CSV-1000 contrast sensitivity test. METHODS Patients with primary open angle glaucoma (N = 16) were retrospectively evaluated to determine changes in visual function, as measured by contrast sensitivity, after beta-blocker therapy. A control grou...

Progressive amyloid deposition in senile plaques and cortical blood vessels may play a central role in the pathogenesis of Alzheimer disease. We have used x-ray diffraction and electron microscopy to study the molecular organization and morphology of macromolecular assemblies formed by three synthetic peptides homologous to beta protein of brain amyloid: beta-(1-28), residues 1-28 of the beta p...

Childhood or pediatric glaucomas are a heterogeneous group, comprising the true primary developmental glaucomas, associated with developmental anomalies in the eye since birth and other secondary glaucomas. Early onset primary open angle glaucoma, the so called juvenile glaucoma, as well as angle closure glaucomas both primary and secondary are also seen in the pediatric age group. Pediatric gl...

We present new constraints on the frequency dependence of cosmic birefringence angle from Planck data release 4 polarization maps. An axion field coupled to electromagnetism predicts a nearly frequency-independent angle, $\beta_\nu = \beta$, while Faraday rotation local magnetic fields and Lorentz violating theories predict that is proportional frequency, $\nu$, power some integer $n$, \propto ...

The development of the chamber angle was studied in the eyes of heterozygous Pax6(lacZ/+) mutant mice (Nature 387 (1997) 406). Mutations in PAX6 cause aniridia, a condition that is frequently associated with glaucoma, a blinding disease that may be associated with chamber angle defects. Mesenchymal cells were seen in the chamber angle at P1-P5. In wild-type mice, these cells differentiated into...

Differences in aortic impedance between normotensives and hypertensives are not well characterized. We examined impedance in 8 normotensive and 11 hypertensive (mean 96.7 vs. 122.2 mmHg) age-matched, Chinese patients undergoing cardiac catheterization at rest, during nitroprusside, and handgrip exercise before and after beta blockade (propranolol). Hypertensives had higher resistance (2,295 vs....

statement of problem: the gonial angle plays an important role in ensuring a harmonious facial profile. changes in this angle especially after surgery may be an aesthetic concern for both the patient and the surgeon. purpose: the aim of the present study was to evaluate gonial angle changes after mandiblular setback with the bssro technique and to measure postsurgical relapse two years after su...
