Predictive factors for functional improvement following intravitreal bevacizumab injections after central retinal vein occlusion.

Purpose: Vision loss in central retinal vein occlusion (CRVO) is mostly caused by macular edema (ME) and can be treated with intravitreal bevacizumab injections. The goal of this study was to identify predictive factors for improvement in visual acuity.

Methods: Three hundred and sixteen eyes of six centres having received intravitreal bevacizumab for ME due to CRVO were enrolled in this multicentre, retrospective, interventional case series.

Long-term results after artificial iris implantation in patients with aniridia.

Background: The custom-made, flexible artificial iris developed by HumanOptics and Koch can reconstruct the anterior segment of patients with aniridia. The aim of this study was to evaluate the long-term clinical outcome and complication spectrum after artificial iris implantation and the role of the embedded fiber mesh in view of specific complications.

Methods: In this retrospective interventional case series, patients received an artificial iris between 2004 and 2013.

Customized humanoptics silicone iris prosthesis in eyes with posttraumatic iris loss: outcomes and complications.

Purpose: Posttraumatic partial or total iris defects often cause significant debilitating glare, photophobia, decreased vision and cosmetic problems. Currently, the best cosmetic results can be obtained with a customized silicone iris prosthesis. However, little is known about the functional results and the rate of complication if this type of iris prosthesis is implanted into severely traumatized eyes.

A modified scleral dissection technique with suprachoroidal drainage for canaloplasty.

Purpose: A modified canaloplasty technique is described that may facilitate the surgical procedure and potentially maximizes the intraocular pressure (IOP)-lowering effect by altering both the trabecular and uveoscleral aqueous outflow.

Methods: The second deeper layer in the modified technique (about 3.5 × 4 mm, Fig.

Critical evaluation of the usability of augmented reality ophthalmoscopy for the training of inexperienced examiners.

Purpose: To measure the value of augmented reality technology usage to teach the medical students performing binocular indirect ophthalmoscopy.

Methods: Thirty-seven medical students were randomly assigned to the training of binocular indirect ophthalmoscopy either in the conventional way or with augmented reality ophthalmoscopy (ARO). For testing student's skills, they had to examine a real person using a conventional ophthalmoscopy system and draw the optic disk.
