Predictors of response to a lapse in anti-VEGF treatment in patients with macular edema secondary to retinal vein occlusion.

Background: Macular edema (ME) in the setting of retinal vein occlusions (RVO) is a common cause of vision loss worldwide. Anti-vascular endothelial growth factor (anti-VEGF) injections are the gold standard for ME secondary to RVO. Despite their efficacy, anti-VEGF injections carry significant burdens for patients, resulting in high rates of loss to follow-up and treatment lapses.

Consequences of anti-vascular endothelial growth factor treatment lapse in patients with retinal vein occlusion.

Background: Anti-vascular endothelial growth factor (VEGF) treatments are the first-line treatment for Retinal Vein Occlusion (RVO). Although effectiveness and safety of these treatments is well documented, knowledge regarding the effect of lapses in anti-VEGF treatment among RVO patients is lacking. The purpose of this study is to analyse the anatomic and visual outcomes from a lapse in anti-VEGF treatment in patients with RVO.

Assessment of inner and outer retinal layer metrics on the Cirrus HD-OCT Platform in normal eyes.

Purpose: Ellipsoid zone (EZ) and outer retinal integrity are strongly linked to visual prognosis, but quantitative normative data is lacking. This study evaluates the EZ, outer retina, and inner retina in eyes without macular disease across a wide age spectrum.

Methods: An IRB-approved study was performed for eyes without macular pathology undergoing Spectral Domain Optical Coherence Tomography (SD-OCT) scans on the Cirrus HD-OCT system (Carl Zeiss Meditec, Oberkochen, Germany).

Accuracy of navigation in hip resurfacing with different surgeons and varying anatomy.

The accuracy of a commercial imageless navigation system for hip resurfacing and its reproducibility among different surgeons and for varying femoral anatomy was tested by comparing conventional and navigated implantation of the femoral component on different sawbones in a hip simulator. The position of the component was measured on postoperative radiographs. Variance for varus/valgus alignment and anteversion was higher for conventional implantation.
