Prevalence and clinical correlates of focal choroidal excavation in eyes with age-related macular degeneration, polypoidal choroidal vasculopathy and central serous chorioretinopathy.

Purpose: To describe the prevalence and clinical characteristics of focal choroidal excavation (FCE) in patients with exudative maculopathy due to age-related macular degeneration with choroidal neovascularisation (AMD-CNV), polypoidal choroidal vasculopathy (PCV) and central serous chorioretinopathy (CSC).

Methods: Three hundred and forty-three patients (343 presenting eyes and 255 fellow unaffected eyes) from consecutive patients presenting with untreated AMD-CNV, PCV or CSC are prospectively recruited. Two independent retinal specialists masked to the clinical diagnosis graded the presence of FCE by examining the findings from spectral-domain optical coherence tomography (SD-OCT).

MYOPIC RETINOSCHISIS IN ASIANS: Structural Features and Determinants of Visual Acuity and Prognostic Factors for Progression.

Purpose: To describe microstructural changes and schisis extent in eyes with myopic retinoschisis and to determine their influence on visual acuity at baseline and follow-up.

Methods: In this prospective observational study, 50 eyes of 38 patients with myopic retinoschisis were evaluated using spectral domain optical coherence tomography, and the patients were followed for at least 12 months. The presence of microstructural changes and the extent of retinoschisis at baseline on spectral domain optical coherence tomography, and the association between these parameters and the risk of visual acuity deterioration were analyzed.

SCLERAL BUCKLING VERSUS VITRECTOMY IN THE MANAGEMENT OF MACULA-OFF PRIMARY RHEGMATOGENOUS RETINAL DETACHMENT: A COMPARISON OF VISUAL OUTCOMES.

Purpose: To compare visual outcomes between pars plana vitrectomy (PPV) with or without scleral buckling (SB) and SB alone in the management of uncomplicated macula-off primary rhegmatogenous retinal detachment.

Methods: Case-control study of 723 patients with uncomplicated macula-off primary rhegmatogenous retinal detachment seen at the Singapore National Eye Centre from 2005 to 2011. The primary outcome measure was the proportion of eyes achieving functional success, defined as logMAR best-corrected visual acuity of ≤0.

New loci and coding variants confer risk for age-related macular degeneration in East Asians.

Age-related macular degeneration (AMD) is a major cause of blindness, but presents differently in Europeans and Asians. Here, we perform a genome-wide and exome-wide association study on 2,119 patients with exudative AMD and 5,691 controls, with independent replication in 4,226 patients and 10,289 controls, all of East Asian descent, as part of The Genetics of AMD in Asians (GAMA) Consortium. We find a strong association between CETP Asp442Gly (rs2303790), an East Asian-specific mutation, and increased risk of AMD (odds ratio (OR)=1.

A prospective study of treatment patterns and 1-year outcome of Asian age-related macular degeneration and polypoidal choroidal vasculopathy.

Objective: To study the treatment patterns and visual outcome over one year in Asian patients with choroidal neovascular membrane secondary to age-related macular degeneration (AMD-CNV) and polypoidal choroidal vasculopathy (PCV).

Design: Prospective cohort, non-interventional study.

Methods: 132 treatment-naïve patients who received treatment for AMD-CNV and PCV were included.

Trends in age-related macular degeneration management in Singapore.

Purpose: To describe the trends and patterns of anti-vascular endothelial growth factor (anti-VEGF) therapy and photodynamic therapy (PDT) use for age-related macular degeneration (AMD) in the National Eye Centre in Singapore over a 4-year period.

Methods: Data on the total number of intravitreal anti-VEGF injections and PDT treatment over a 4-year period at the Singapore National Eye Centre were obtained from centralized electronic records. Patients aged 40 years and older treated for AMD were included.

Trends and factors related to outcomes for primary rhegmatogenous retinal detachment surgery in a large asian tertiary eye center.

Purpose: To describe trends and outcomes of vitreoretinal surgery for primary rhegmatogenous retinal detachment in a large Asian tertiary eye center.

Methods: Retrospective review of 1,530 eyes with primary retinal detachment between 2005 and 2011 managed at the Singapore National Eye Center by one of the following: scleral buckling (SB), pars plana vitrectomy (PPV), and combined SB and PPV (SB + PPV). Anatomical and functional outcomes were assessed.

Prognostic factor analysis of vitrectomy for retinal detachment associated with myopic macular holes.

Purpose: To describe the anatomic and functional outcomes in a cohort of subjects undergoing vitrectomy for retinal detachment (RD) resulting from myopic macular hole (MH) and to analyze the prognostic and surgical factors predicting retinal reattachment and MH closure.

Design: Retrospective case series.

Participants: All patients who underwent vitrectomy for RD resulting from myopic MH between 2000 and 2009 at our center.

Development of thyroid-related orbitopathy following cataract surgery.

Aim: To report a case series of patients who had manifestation or aggravation of thyroid related orbitopathy (TRO) following cataract surgery in an Asian eye centre.

Methods: A systematic review of clinical records of patients with manifestation or aggravation of TRO was conducted. Inclusion criteria were manifestation or aggravation of TRO within 6 months of cataract surgery.

Foveolitis associated with dengue Fever: a case series.

Background: Dengue fever (DF), a viral infection caused by dengue virus, is characterized by fever, headache, muscle and joint pains. Approximately 50-100 million people are infected annually. Ocular manifestations during DF are uncommon and include intraretinal hemorrhages and cotton wool spots; manifestations predominantly characterized by foveal involvement have not been described before in DF or any other retinopathies.
