PURPOSE To measure choroidal thickness (CT) in myopic eyes using enhanced depth imaging (EDI). DESIGN A cross-sectional study. PARTICIPANTS Fifty-six consecutive patients with spherical equivalent refractive error of at least 6 diopters (D) were evaluated. METHODS Enhanced depth imaging optical coherence tomography (OCT) images were obtained by(More)
Neovascular age-related macular degeneration (AMD) and polypoidal choroidal vasculopathy (PCV) are leading causes of irreversible blindness in developed countries. In this study, we investigated the associations of haplotype-tagging single nucleotide polymorphisms (SNPs) in the complement component 3 (C3) gene with both neovascular AMD and PCV, and(More)
PURPOSE To investigate long-term efficacy and prognostic factors of half-dose photodynamic therapy (PDT) in chronic central serous chorioretinopathy (CSCR). DESIGN Retrospective multicenter interventional case series. METHODS Patients with chronic CSCR undergoing half-dose PDT between 2005 and 2011 were reviewed. Main outcome measures included(More)
PURPOSE To compare the incidence of postoperative endophthalmitis before and after the implementation of a preoperative surgical site preparation protocol for cataract surgery. DESIGN Retrospective cohort study. METHODS Records of patients with postoperative endophthalmitis between January 2006 and August 2013 were reviewed. A revised protocol(More)
To report a case of bilateral varicella zoster virus (VZV)-associated acute retinal necrosis (ARN) occurring after both eyes sequential cataract surgery in an elderly immunocompromised patient. Medical records and investigation results of the patient were reviewed. Patient experienced floaters and blurring of vision in both eyes 4 weeks after her second(More)
The purpose of this study was to study the etiologies and operative outcomes of pediatric retinal detachment at a tertiary eye referral center in Hong Kong over a 10-year period. A retrospective study of patients (below 18 years of age) who received primary retinal detachment repair operations at a University Teaching Hospital between 2005 and 2015 was(More)
Purpose We determine the angiopoietin 2 (ANGPT2) gene as a new susceptibility gene for neovascular age-related macular degeneration (nAMD) and polypoidal choroidal vasculopathy (PCV). Methods A total of 34 haplotype-tagging single-nucleotide polymorphisms (SNPs) were first genotyped in an exploratory Hong Kong Chinese cohort. Suggestive SNPs were(More)
Purpose We investigated the association of the ATP-binding cassette, subfamily G, member 1 (ABCG1) gene with polypoidal choroidal vasculopathy (PCV) and neovascular age-related macular degeneration (nAMD) in independent Chinese and Japanese cohorts. Methods A total of 12 haplotype-tagging single-nucleotide polymorphisms (SNPs) and the SNP rs57137919 in(More)
