The Age-Related Maculopathy Susceptibility 2 Polymorphism and Polypoidal Choroidal Vasculopathy in Asian Populations: A Meta-Analysis – Corrected Proof

2013/05/20
By
Objective: To assess the role of the age-related maculopathy susceptibility 2 (ARMS2) A69S polymorphism as a risk factor for polypoidal choroidal vasculopathy (PCV) in Asian populations.Methods: We performed a meta-analysis of the association of the A69S variant with PCV in Asian populations using data available from 14 case-control studies involving 6552 subjects. Summary odds ratios (ORs) and 95% confidence intervals (CIs) were estimated using fixed- and random-effects models. Sensitivity analysis also was performed.Main Outcome Measure: Understanding the relationship between the A69S variant and PCV is essential to provide new insights into pathophysiology and potential targets for intervention of PCV.Results: The (Read more...)

The Posterior Pole and Papillomacular Fold in Posterior Microphthalmos: Novel Spectral-Domain Optical Coherence Tomography Findings – Corrected Proof

2013/05/20
By
Purpose: To report and analyze the spectral-domain optical coherence tomography (SD-OCT) features of the posterior pole and papillomacular fold (PMF) in posterior microphthalmos (PM) in relation to axial length of the globe and corneal power.Design: Comparative case series.Participants: Forty eyes of 20 PM patients and 70 eyes of 35 age-matched controls.Methods: All PM and control eyes underwent a full biometric evaluation, including axial length and corneal power measurements, and macular SD-OCT. In addition, a novel SD-OCT marker of the posterior pole curvature, termed the posterior pole curvature index (PPCI), was measured along both the vertical and horizontal meridians. The OCT characteristics of the (Read more...)

Enhanced Depth Imaging Optical Coherence Tomography of the Choroid in Central Retinal Vein Occlusion – Corrected Proof

2013/05/20
By
Purpose: To evaluate subfoveal choroidal thickness in patients with central retinal vein occlusion (CRVO) using enhanced depth imaging optical coherence tomography.Design: Retrospective observational study.Methods: We measured bilateral subfoveal choroidal thickness, averaged for 100 scans, in 36 patients (mean age, 66 ± 15 years; 26 women and 10 men) with unilateral CRVO by using the enhanced depth imaging methods of the Spectralis optical coherence tomography system. Twenty-two patients were treated with intravitreal bevacizumab (1.25 mg/0.05 mL), and subfoveal choroidal thickness was measured before and after treatment. Statistical analysis was performed to compare subfoveal choroidal thickness of CRVO and fellow eyes and to compare (Read more...)

Antibiotic prophylaxis might, in fact, have a negative impact on the safety of the procedure, according to a speaker here.Alexander J. Brucker, MD, was awarded the Gian Battista Bietti SOI Medal Lecture 2013 at the annual joint meeting of Ocular Surgery News and the Italian Society of Ophthalmology.

Normal-tension glaucoma progression linked to dips in nocturnal blood pressure

LA JOLLA, Calif. — Decreases in nocturnal blood pressure below the daytime mean arterial pressure and the significance of these dips are linked to normal-tension glaucoma progression, according to a study presented here."Glaucoma is a chronic degenerative disease, and currently the only way to control this progression is to lower intraocular pressure," Carlos Gustavo De Moraes, MD, said at the American Ophthalmological Society meeting.

2013/05/20
By
The most common cause of failure after glaucoma surgery is scarring at the surgical site, so researchers are actively looking for ways to minimize or prevent scar formation. Previous work had suggested that vascular endothelial growth factor (VEGF) activates fibrosis, whereas VEGF inhibition results in reduced scar formation and better surgical results...
