Objectives: To identify the characteristics, treatment, and visual outcomes of dengue uveitis at a tertiary eye care centre in Singapore.
Methods: Retrospective case record review of all consecutive dengue uveitis patients (2004 to 2015) from the Ocular Autoimmune Systemic Inflammatory and Infectious Study (OASIS) database.
Results: Fifty-four patients were identified from the OASIS database.
Purpose: The COVID-19 pandemic has galvanized the development of new vaccines at an unprecedented pace. Since the widespread implementation of vaccination campaigns, reports of ocular adverse effects after COVID-19 vaccinations have emerged. This review summarizes ocular adverse effects possibly associated with COVID-19 vaccination, and discusses their clinical characteristics and management.

A 54-year-old Chinese male with no previous ocular history presented to the ophthalmology department for the bilateral acute painless blurring of vision after receiving the 1st dose of COVID-19 mRNA vaccine (PFIZER-BioNTech/COMIRNATY). Clinical examination and imaging tests were consistent with Vogt-Koyanagi-Hara disease. The patient responded well with a high dose of intravenous methylprednisolone followed by a tapering dose of oral prednisolone.

Currently, there are a number of antiviral agents administered to treat viral anterior uveitis (VAU). However, there is no consensus or guidelines about the most appropriate approach leading for the best treatment outcomes with fewer ocular complications.

Introduction: Intraocular lymphoma is rare. There are very few studies on intraocular lymphoma published from Asian countries.
Objective: To report our case series of intraocular lymphoma patients from a tertiary eye centre in Singapore.
Aim of the study was to examine extent, natural history, and clinical features associated with visual impairment (VI) in patients diagnosed with ocular tuberculosis (OTB) by the Collaborative Ocular Tuberculosis Study (COTS)-1. Multi-center retrospective cohort study. Main outcomes were VI.

The main outcome measure was a number of patients with treatment failure (TF).
View Article and Find Full Text PDFTuberculosis (TB) is a major infection that can affect the eye as first and sole presentation without features of systemic disease. Controversy exists regarding diagnosis and management of tubercular uveitis (TBU), further compounded by regional variations in disease expression. Collaborative Ocular Tuberculosis Study (COTS)-1 aims to address knowledge deficits through collaboration amongst uveitis specialists across the globe by sharing the data of patients with TBU presented at participating centers from January 2004 to December 2014.

Aim: To report the clinical features and outcome of patients with presumed tubercular uveitis (TBU).
Methods: Retrospective analysis of patients with presumed TBU at a tertiary referral eye care centre in Singapore between 2007 and 2012 was done. Main outcome measures were failure of complete resolution of uveitis or recurrence of inflammation.
Purpose: To report the epidemiology and classification of ocular inflammation at a tertiary eye care center in Singapore.
Methods: Retrospective cohort study of the clinical records of consecutive new cases from the Ocular Autoimmune Systemic Inflammatory Infectious Study (OASIS) database from 2004-2015.
Results: A total of 2200 patients were studied from the OASIS database.
Background: Nontuberculous mycobacteria (NTM) are found ubiquitously in the environment. Since exposure to NTM is universal, infection likely represents underlying host susceptibility factors. Anti-IFN-ɣ autoantibodies have been described previously in patients with NTM.

Methods: Retrospective case series.
Results: Two young immunocompetent males who were diagnosed to have unilateral disc swelling were treated as presumed optic neuritis and started on systemic steroids.
Choroidal neovascularization secondary to tuberculous serpiginous-like choroiditis (Tb-SLC) is uncommon and requires further invasive imaging, such as fluorescein and indocyanine green angiography. We evaluate the optical coherence tomography angiography (OCTA) findings in a patient with a Tb-SLC and present the use of this investigation as a non-invasive diagnostic and follow-up clinical tool in this disease.

We report a case of paradoxical worsening of tuberculous chorioretinitis after initiation of anti-tuberculous therapy (ATT). The patient had left panuveitis with tuberculous chorioretinitis and was started on systemic ATT and oral steroids a week later. However, he developed paradoxical worsening 2 months after initiation of therapy.
