AIM To determine the risk factors for developing phacomorphic glaucoma in eyes with mature cataracts. MATERIALS AND METHODS This is a case-control study comprising of 90 eyes with phacomorphic glaucoma and 90 age- and sex-matched control eyes with mature cataracts without phacomorphic glaucoma. Patients with pre-existing glaucoma, previous intraocular(More)
To investigate the etiology and prevalence of optic neuritis in a Chinese population. This was a single centre prospective cohort study. Consecutive patients with either a first or recurrent attack of optic neuritis from November 2010 to December 2011 were recruited from a district hospital in Hong Kong Special Administrative Region, China. All patients(More)
PURPOSE To identify novel corneal biomechanical parameters differentiating glaucomatous from normal eyes. PATIENTS AND METHODS Sixty subjects with varying degrees of glaucoma severity and 61 normal controls underwent corneal biomechanical measurements including corneal deformation amplitude, inward and outward applanation length and velocity, and highest(More)
PURPOSE To determine the predictors of success for adjuvant selective laser trabeculoplasty (SLT) in Chinese primary open angle glaucoma (POAG) patients. METHODS This prospective study recruited Chinese subjects with unilateral or bilateral POAG currently taking medication to reduce intraocular pressure (IOP). All subjects received a single session of(More)
The objective of this study is to determine the incidence and risk factors of retinopathy of prematurity (ROP) in extremely low birth weight (ELBW) Chinese infants. A retrospective medical record review of all ELBW (≤1,000 g) neonates screened for ROP from 2007 to 2012 was performed in Hong Kong. ROP screening was conducted at 2 neonatal intensive care(More)
PURPOSE The purpose of this study was to investigate the efficacy of selective laser trabeculoplasty (SLT) in the treatment of normal tension glaucoma (NTG). METHODS This prospective cohort study recruited consecutive cases of NTG on antiglaucoma medication. Cases were excluded for previous glaucoma surgery or laser. All patients underwent a 1-month(More)
BACKGROUND The objective of this study was to investigate the effects of adjuvant selective laser trabeculoplasty (SLT) versus medication alone on intraocular pressure (IOP) control, medication use, and quality of life in patients with primary open-angle glaucoma. METHODS This prospective, randomized control study recruited 41 consecutive primary(More)
PURPOSE To identify the optimal energy level to be used in selective laser trabeculoplasty (SLT) for maximal intraocular pressure (IOP) reduction in open-angle glaucoma (OAG) patients. PATIENTS AND METHODS This cohort sequentially recruited OAG subjects in Hong Kong, China during 2011 to 2012. All subjects received a single session of SLT with near(More)
BACKGROUND Normal tension glaucoma (NTG) is commonly treated with anti-glaucoma medications. Recently, selective laser trabeculoplasty (SLT) has been demonstrated to lower the intraocular pressure (IOP) and medication use in NTG. The purpose of this study was to investigate the efficacy of a single session of SLT for NTG at 1 year. METHODS This(More)
