PURPOSE To determine whether foveal thickness, foveal volume, visual acuity, and foveal sensitivity after intravitreal injection of triamcinolone acetonide (IVTA) are influenced by the extent of occlusion (major versus macular branch retinal vein occlusion (BRVO)). MATERIALS AND METHODOLOGY In this interventional case series, 22 eyes of 22 BRVO patients with macular oedema were treated by IVT...

Introduction/Objective. During hemodialysis (HD) treatment great fluctuations were recorded in the systemic hemodynamic parameters and volume composition of ocular fluid. There are only a few studies that analyzed effect HD on retinal macular thickness with conflicting results. Objective this study was to determine thickness, marked as central foveal average volume, shortly before after HD. Met...

PURPOSE To evaluate the variation in macular retinal thickness and volume in young Chinese myopic patients using time-domain optical coherence tomography (Stratus TD-OCT) and spectral-domain optical coherence tomography (Cirrus HD-OCT). METHODS Ninety-two eyes of 92 myopic subjects were recruited in this study. Based upon spherical equivalence (SE), subjects were divided into two groups: the ...

BACKGROUND The purpose of this retrospective chart review was to evaluate factors associated with improvement of visual acuity after a single sub-Tenon injection of triamcinolone acetonide in patients with diabetic macular edema. METHODS We reviewed the medical records for 63 consecutive eyes with diabetic macular edema treated by sub-Tenon injection of triamcinolone acetonide and assessed at...

PURPOSE To assess the efficacy of intravitreal use of triamcinolone acetonide combined with laser photocoagulation for the treatment of diffuse diabetic macular edema and to compare it with the separate use of each treatment. METHODS After systemic clinical control, thirty patients with diffuse diabetic macular edema were divided into 3 treatment groups: (1) macular grid photocoagulation; (2)...

Purpose Ocular and systemic measurement and imaging of the macular carotenoids lutein and zeaxanthin have been employed extensively as potential biomarkers of AMD risk. In this study, we systematically compare dual wavelength retinal autofluorescence imaging (AFI) of macular pigment with skin resonance Raman spectroscopy (RRS) and serum carotenoid levels in a clinic-based population. Methods ...

PURPOSE To investigate the relationship between morphological changes of the optic nerve head (ONH) and macular sensitivity determined with blue on yellow (B on Y) and white on white (W on W) perimetry in normal subjects and patients with glaucoma. METHODS One randomly chosen eye was evaluated in each of 28 healthy subjects, 23 patients with ocular hypertension (OH), and 23 patients with earl...

PURPOSE To evaluate the efficacy of prophylactic ketorolac 0.5% versus nepafenac 0.1% versus placebo on macular volume 1 month after uneventful phacoemulsification and evaluate the health-related quality-of-life (HRQOL) of topical nonsteroidal antiinflammatory drugs (NSAIDs) in the context of cataract surgery. SETTING Hotel Dieu Hospital, Kingston, Ontario, Canada. DESIGN Prospective placeb...

BACKGROUND The aim was to report normative values of retinal nerve fiber layer (RNFL) and macular parameters in children using spectral domain optical coherence tomography (OCT) and to perform correlations with age, refractive error and axial length. METHODS This was an observational cross-sectional study recruiting 113 healthy children aged 6 to 17 years with no ocular abnormality except ref...

PURPOSE To evaluate macular thickening, the state of the optic disc and retinal nerve fibers layer (RFNL) in patients with an actual episode of acute anterior uvetis (AAU) by optical coherence tomography (OCT), and compare them with a control group. METHODS In this prospective, cross-sectional, observational and controlled study we recruited 27 consecutive eyes of 20 patients with an actual e...
