RPE use similar pathway to regulatory T cells to inhibit immune response

Retinal pigment epithelial (RPE) cells form an important part of the blood-retinal barrier that protects the neuronal cells responsible for sight. RPE cells are involved in innate and adaptive immune responses via expression of surface molecules and release of cytokines....

Pars plana vitrectomy for vitreomacular traction syndrome

This paper presents a meta-analysis and systematic review of the safety and efficacy of vitrectomy for vitreomacular traction (VMT), based on 21 eligible articles from 460 identified. A strength of this study is that it provided pooled analysis across a...

Understanding optic nerve head pericytes and glaucoma

The authors provide a comprehensive review of the current understanding of pericytes in the optic nerve head (ONH). Key points include: (1) Pericytes are contractile mural cells that play crucial roles in regulating blood flow, maintaining the blood-brain / blood-retinal...

Aug/Sep 2015 Quiz 2

History A two-year-old female child presented with loss of vision in her left eye. Examination showed leukocoria and intraocular calcification was identified on scanning. The suspected diagnosis was intraocular retinoblastoma and the child underwent an enucleation. The eyeball was submitted...

Preoperative RPE alterations in macular holes

This retrospective interventional case series from Japan assessed whether preoperative alterations of the retinal pigment epithelial (RPE) in idiopathic macular holes correlated with postoperative functional and morphological changes in the macula. Fifty-nine eyes had preoperative Spectralis OCT using the ‘detailed’...

Prognostic information for PRP-naive patients

The Diabetic Retinopathy Study group demonstrated that pan retinal laser photocoagulation (PRP) reduces severe vision loss by up to 50% in cases of proliferative diabetic retinopathy (PDR). The authors of this current study aimed to provide information for laser naive...

CD40L activation of human RPE cells

Age-related macular degeneration (AMD) is the leading cause of reduced visual acuity in the elderly worldwide. The risk factors involved in AMD include smoking and diet, while genetics have been shown to have a significant role. Recently a link between...

Macular thickness and visual fields

The authors describe a comparison of spectral domain OCT with Humphrey visual fields (HVF) mean deviation (MD) and pattern standard deviation (PSD), examining the retinal thickness of the macula and circumpapillary retinal nerve fibre layer (RNFL) defects. Seventy-three subjects who...

Renewed momentum in ocular gene and cell therapy, broadening application to chronic disease

Gene and cell therapies offer the prospect of ground-breaking new avenues for the treatment of diseases, reflected in a renewed explosion of interest and investment in retinal gene therapy. Rod McNeil reports recent clinical trial readouts across a diverse range...

Using optical coherence tomography angiography to detect MoyaMoya vasculopathy

Moyamoya (MM) disease is a chronic cerebrovascular disease that can lead to progressive stenosis of the terminal portions of the internal carotid arteries and their proximal branches. The authors carried out a cross-sectional cohort study to investigate vascular changes in...

OCT use with macular retinoblastoma

The authors explore the use of portable hand-held spectral domain OCT (SD-OCT) in three eyes of three infants and young children with macular retinoblastoma. All were treated with chemotherapy and all had SD-OCT before and after treatment. The children were...

Occurrence and risk factors for RD after PPV in acute postcataract bacterial endophthalmitis

This is a prospective multicentre study from France between March 2004 to December 2011 in four university hospitals; 123 consecutive patients treated with pars planar vitrectomy (PPV) were included in this cohort. The rate of retinal detachment (RD) of post-PPV...
