Methods: In 57 eyes of 30 patients who were referred for doppler ultrasound examination of the ICA we measured POBF and analyzed the correlation with degree of ipsilat-eral ICA stenosis. Results: There was a significant negative correlation between POBF and ipsilateral ICA stenosis (Pearson correlation coefficient, r =-0.516, P< 0.0001). In 14展开更多
Epidemiological studies suggest that glaucoma exists in the presence of both elevated and normal intraocular pressures (IOP). Further, reduction of IOP does not necessarily prevent progression of glaucomatous damage. ...Epidemiological studies suggest that glaucoma exists in the presence of both elevated and normal intraocular pressures (IOP). Further, reduction of IOP does not necessarily prevent progression of glaucomatous damage. The normal tension glaucoma study found that visual field progression occurred at indistinguishable rates in a group of normal tension展开更多
Purpose: Open angle glaucoma (OAG) is known to demonstrate an hereditary pattern. The pattern, severity and progression of OAG in first degree relatives were evaluated and compared. Methods: Six pairs of first degree ...Purpose: Open angle glaucoma (OAG) is known to demonstrate an hereditary pattern. The pattern, severity and progression of OAG in first degree relatives were evaluated and compared. Methods: Six pairs of first degree relatives (five parent/child, one pair identical twins) with OAG were reviewed. The pattern of glaucoma within each pair of family members was compared,展开更多
Purpose: Raloxifene is known to reduce flow resistance in selected vasculature. This study examined the effect of raloxifene, a selective estrogen receptor modulator (SERM) on retrobulbar blood flow. Methods: Right ey...Purpose: Raloxifene is known to reduce flow resistance in selected vasculature. This study examined the effect of raloxifene, a selective estrogen receptor modulator (SERM) on retrobulbar blood flow. Methods: Right eyes of fifteen postmenopausal women receiving raloxifene were compared with right eyes of fifteen postmenopausal age-matched women not receiving raloxifene. Using color Doppler imaging the peak systolic velocity (PSV),展开更多
