DESIGN/METHODOLOGY/APPROACH Prospective non-randomised cohort study. A standardised questionnaire of five common ocular symptoms (general condition, vision, eye pain,(More)
BACKGROUND To investigate and compare the effect of cataract and pupil size on retinal nerve fibre layer (RNFL) thickness measurements using spectral-domain optical coherence tomography (Cirrus OCT) and time-domain OCT (Stratus OCT). DESIGN   Prospective, hospital-based study. PARTICIPANTS Twenty-five eyes from 25 normal subjects undergoing cataract(More)
PURPOSE To determine the incremental cost-effectiveness of a new telemedicine technician-based assessment relative to an existing model of family physician (FP)-based assessment of diabetic retinopathy (DR) in Singapore from the health system and societal perspectives.

PURPOSE To determine whether selective laser trabeculoplasty (SLT) can lower intraocular pressure (IOP) in eyes with chronic primary angle closure, elevated IOP, and a patent iridotomy. PATIENTS AND METHODS Patients with chronic angle closure who had underwent iridotomy, had an IOP greater than 21 mm Hg and a gonioscopically visible pigmented trabecular(More)
PURPOSE To determine the incidence and baseline clinical and anterior segment optical coherence tomography (AS-OCT) predictors associated with residual angle closure as assessed by gonioscopy 1 year after laser peripheral iridotomy (LPI) in primary angle closure suspects (PACS). DESIGN Subanalysis of randomized controlled trial data. METHODS AS-OCT(More)
