MicroRNA mediate retinoblastoma signal transduction

MicroRNAs (miR) are small non-coding single-stranded RNA molecules, normally 22 nucleotides long. There is a large family of miR that control protein expression by binding to mRNAs, leading to their degradation. One important role of miR is in tumours where...

Retinal pigment epithelium tears

In this paper the authors review the current knowledge of retinal pigment epithelium (RPE) tears. Although rare these can cause loss of visual acuity. They can occur spontaneously in pigment epithelial detachment (PED) due to occult choroidal neovascularisation (CNV), retinal...

Combined anti-VEGF and PDT for wet AMD

The authors report on a retrospective case series of combined anti-VEGF and photodynamic therapy (PDT) in the treatment of wet age-related macular degeneration (AMD) refractory to anti-VEGF monotherapy alone. The criteria for treatment failure of anti-VEGF monotherapy were persistent subretinal...

Swept-source OCT for measuring peripheral anterior synechiae

The authors report on a cross-sectional study looking at swept-source optical coherence tomography (SS-OCT) for measuring the area and degree of peripheral anterior synechiae (PAS) in patients with angle closure glaucoma. The SS-OCT is commercially available, has a laser wavelength...

RPE tears in cases of IPCV

The aim of this study was to investigate the occurrence, characteristics, management and prognosis of retinal pigment epithelium (RPE) tears in patients with polypoidal choroidal vasculopathy (PCV). Medical records of previous cases were reviewed over an eight-year period from a...

Transient macular thinning with Densiron 68

Densiron 68 is a heavy silicone oil (HSO) used to treat rhegmatogenous retinal detachments (RRD) with inferior retinal breaks. The authors compared changes in retinal thickness during and after the use of Densiron endotamponade, and looked at any association between...

Intravitreal triamcinolone for uveitic macular oedema

This paper from South Korea reports on a prospective, double blind, randomised clinical study designed to evaluate the additional benefit of intravitreal triamcinolone (TA) administration for noninfectious uveitic macular oedema as an adjunct therapy to systemic anti-inflammatory treatment. Patients were...

OCT positioning regimen in macular hole surgery

The authors set out to evaluate an OCT-based positioning regimen for macular hole surgery. Patients were advised to maintain prone positioning until the hole was confirmed to be closed based on daily OCTs. Surgery consisted of 23-gauge phacovitrectomy with internal...

The choroid in pregnancy

During pregnancy there can be different types of ocular changes including a decrease in corneal sensitivity, increase in central corneal thickness and curvature, decrease in intraocular pressure, central serous chorioretinopathy and ocular blood flow. Advances in ophthalmic imaging devices has...

C-spp corneal consequences

This is a retrospective review of microbiological records of 22 patients, who had presented at the LV Prasad Eye Institute, India, between June 2009 and December 2012. The corneal scrapings were performed in all patients and had yielded significant growth...

Preoperative povidone iodine: weighing the risks

Following on from our recent online survey, the authors examine the potential risks and benefits of diluting the concentration preoperative povidone iodine. Povidone iodine (PI) is an iodophore that has an established use as a broad-spectrum antiseptic, mainly for the...

Aberration measurements with manual or FLA cataract surgery

This study group compared the higher order aberrations (HOAs) between femtosecond laser-assisted cataract surgery (FLACS) and manual cataract surgery. Consecutive patients undergoing FLACS or manual cataract surgery with implantation of an intraocular lens from January 2017 to February 2018 were...
