Introduction: We performed a prospective, single-center, cohort study in order to evaluate the effects of vitrectomy with epiretinal membrane (ERM) peel on optical quality in patients with primary ERM.

Methods: Thirty patients treated for primary ERM by vitrectomy with ERM peel were included from our tertiary university hospital ophthalmology department. The main study outcome was a variation in optical quality parameters measured using the HD Analyzer™ between preoperative and 2-month postoperative evaluations in operated eyes.

Neuro-ophthalmological changes have been reported after prolonged exposure to microgravity; however, the pathophysiology remains unclear. The objectives of the present study were twofold: (1) to assess the neuro-ophthalmological impact of 21 days of head-down bed rest (HDBR) and (2) to determine the effects of resistance vibration exercise (RVE) alone or combined with nutritional supplementation (NeX). In this case, 12 healthy male subjects completed three interventions of a 21-day HDBR: a control condition without countermeasure (CON), a condition with resistance vibration exercise (RVE) comprising of squats, single leg heel and bilateral heel raises and a condition using also RVE associated with nutritional supplementation (NeX).

The spectrum of Myelin Oligodendrocytes Glycoprotein (MOG) antibody disease constitutes a recently described challenging entity, referring to a relatively new spectrum of autoimmune disorders with antibodies against MOG predominantly involving the optic nerve and spinal cord. The purpose of this article is to describe MRI features of MOG-AD involvement in the optic nerves, spinal cord and the brain of adults.

Hearing loss and visual impairment in childhood have mostly genetic origins, some of them being related to sensorial neuronal defects. Here, we report on eight subjects from four independent families affected by auditory neuropathy and optic atrophy. Whole-exome sequencing revealed biallelic mutations in FDXR in affected subjects of each family.

Objectives: To identify prognostic factors associated with poor visual recovery and chronic relapsing diseases, for example, multiple sclerosis (MS), in children with optic neuritis (ON) at onset.

Methods: This multicentre retrospective study included 102 children with a first ON episode between 1990 and 2012. The primary criterion was poor visual recovery determined by visual acuity, and the secondary was relapses following ON.

Aims: To improve the cytological diagnosis of retinal lymphoma on vitreous fluid using improved cell collection and systematic analyses.

Methods And Results: Since October 2010, we have developed and optimized in our department a method with which to perform the diagnosis of retinal lymphoma. The vitreous sample was collected in a tube containing RPMI-1640 medium, decomplemented fetal bovine serum, and gentamicin.

Purpose: To evaluate safety of medium-chain triglycerides used as a possible intraocular tamponading agent.

Methods: A 20-gauge pars plana vitrectomy was performed in the right eye of 28 rabbits. An ophthalmologic examination was performed every week until rabbits were killed.

Foxn4, a member of the N-family forkhead transcription factors, controls fate decision in mouse retina and spinal cord as well as in zebrafish heart. Analysis of Foxn4 amino acid sequence revealed the presence of a region homologous to the activation domain of its close relative Foxn1 in between C-terminal amino acids 402 and 455 of Foxn4 protein. The requirement of Foxn4 putative activation domain remains to be elucidated.

Purpose: To determine risk factors of choroidal detachment after scleral buckling procedure for treatment of retinal detachment.

Design: Retrospective chart review.

Methods: The authors performed a retrospective study of 69 consecutive cases of retinal detachment from January 2007 to January 2008 treated by scleral buckling surgery.

Purpose: To assess the efficacy and safety of a heavy silicone oil (Densiron 68 a mixture of perfluorohexyloctane (F(6)H(8)) with silicone oil as temporary internal tamponade in selected retinal detachments treated with large inferior retinectomy.

Methods: Complicated retinal detachments with severe posterior and anterior proliferative vitreoretinopathy (PVR) were included in this study. In all cases, a large inferior retinectomy involving the inferior quadrants was performed.

Endothelial decompensation is a serious complication of phakic intraocular lens (pIOL) implantation and is a major concern during the postoperative period. We report 3 eyes in which the same foldable angle-supported pIOL was implanted to correct high myopia. Rapid and severe postoperative endothelial cell loss occurred in all 3 eyes.
