To explore whether there are ethnic differences in relationships among parathyroid hormone (PTH), vitamin D, and bone mineral status, 352 healthy volunteers, 60-83 years old, were studied in Shenyang, Peoples' Republic of China (108 men, 110 women), and in Cambridge, UK (67 men, 67 women), in late winter. Early morning fasting blood and 2-h fasting urine(More)
PURPOSE To describe the use of subretinal trypan blue to identify retinal breaks during vitrectomy for rhegmatogenous retinal detachment (RD). DESIGN Interventional case series. PARTICIPANTS Five patients with RD in whom no retinal break could be identified by internal search with scleral indentation. METHODS Trypan blue 0.15% was injected(More)
PURPOSE To determine prospectively among patients with diabetic macular edema (DME) the frequency of a clinically evident taut thickened posterior hyaloid (TTPH), optical coherence tomography (OCT) signs suggestive of partial vitreomacular separation (PVMS), and OCT evidence of subretinal fluid (SRF) and to investigate for associations between these(More)
INTRODUCTION End-stage diabetic eye disease is an important cause of severe visual impairment in the working-age group. With the increasing availability of refined surgical techniques as well as the early diagnosis of disease because of screening, one would predict that the prevalence of this condition is decreasing and the visual outcome is improving.

BACKGROUND/AIMS Most surgeons performing macular hole surgery using long acting gas recommend strict postoperative face down posturing for 10-15 days. Patients with chronic systemic illness such as arthritis may be unable to carry out this postoperative regime. Thus there is a need for alternative techniques that would eliminate such a regime.

The aim of this study was to provide insight into the bone mineral status and biochemical markers of bone metabolism in a Chinese population from Shenyang, in the north of China, where hip fracture incidence is low. A total of 194 healthy men and women, aged 25-35 years and 65-75 years, were studied. Bone mineral density (BMD) at the lumbar spine (LS) and(More)
A prospective study was carried out to test the null hypothesis that there is no additional benefit to be gained from second eye cataract extraction. Twenty-nine patients with unilateral cataract but contralateral pseudophakia completed a questionnaire enquiring into their visual disability and underwent testing of monocular and binocular visual acuity,(More)
PURPOSE To report the clinical features and management of two patients with pseudophakic anterior capsule contraction with secondary tractional ciliary body detachments and hypotonous choroidal effusions. METHODS Case reports. RESULTS In two eyes of two patients with pseudophakia, severe anterior lens capsule contraction and tractional ciliary body(More)
In this prospective study patients with small traumatic hyphaemas were managed as ambulatory outpatients. No routine systemic or topical treatment was given. The patients were reviewed daily in the Casualty Department until the blood had cleared, after which they were examined fully. The incidence of rebleeding and the number of days for the blood to clear(More)
