BACKGROUND A new commercially available optical low coherence reflectometry device (Lenstar, Haag-Streit or Allegro Biograph, Wavelight) provides high-resolution non-contact measurements of ocular biometry. The study evaluates the validity and repeatability of these measurements compared with current clinical instrumentation. METHOD Measurements were(More)
Biliary strictures remain the most challenging aspect of adult right lobe living donor liver transplantation (RLDLT). Between 04/2000 and 10/2005, 130 consecutive RLDLTs were performed in our center and followed prospectively. Median follow-up was 23 months (range 3-67) and 1-year graft and patient survival was 85% and 87%, respectively. Overall incidence(More)
PURPOSE The authors relate the observed reduction in intraocular pressure (IOP) after excimer laser treatment to the degree of myopia treated. BACKGROUND Intraocular pressure, measured by both Goldmann applanation and noncontact tonometry, has been reported to decrease after excimer laser photorefractive keratectomy (PRK). However, IOP readings after(More)
AIM The aim of this study was to evaluate the practicality and accuracy of tonometers used in routine clinical practice for established keratoconus (KC). METHODS This was a prospective study of 118 normal and 76 keratoconic eyes where intraocular pressure (IOP) was measured in random order using the Goldman applanation tonometer (GAT), Pascal dynamic(More)
PURPOSE To compare the efficacy of topical aqueous indomethacin and ketorolac for pain relief following excimer laser photorefractive keratectomy (PRK). METHODS We conducted a double masked, randomized trial involving 120 patients. All patients received a standard regimen of one of the trial drugs and chloramphenicol ointment to be used four times daily(More)
In women, during pregnancy, there is decreased motility of the gastrointestinal tract leading to a delay in gastric emptying and an increase in colonic transit time. Whether the rise in estradiol (E2) or progesterone (P4) is responsible for this effect is controversial. As the nitrergic component of the nonadrenergic, noncholinergic (NANC) nerves is(More)
This study evaluated whether increased release of nitric oxide (NO) from the nitrergic component of the nonadrenergic, noncholinergic (NANC) nerves may be partly responsible for the decrease in gastrointestinal motility observed during pregnancy. Segments of fundal strip, ileum, and colon were obtained from nonpregnant rats, rats in midpregnancy (days(More)
PURPOSE To compare corneal thickness measurements using Orbscan II (OII) and ultrasonic (US) pachymetry in normal and in keratoconic eyes. SETTING Eye Department, Heartlands and Solihull NHS Trust, Birmingham, United Kingdom. METHODS Central corneal thickness (CCT) was measured by means of OII and US pachymetry in 1 eye of 72 normal subjects and 36(More)
Right lobe living donor liver transplantation (RLDLT) is not yet a fully accepted therapy for patients with end-stage liver failure in the Western hemisphere because of concerns about donor safety and inferior recipient outcomes. An outcome analysis from the time of listing for all adult patients who were listed for liver transplantation (LT) at our center(More)
