OCT, Retinal detachment, heavy silicone oil, macula
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...

In this study, the authors assessed retinal sensitivity before and after cataract extraction, in an effort to understand how lens opacities may affect microperimetry results in glaucoma and macular diseases. Thirty patients awaiting cataract extraction were examined and their lens...

This is a review article looking at the differential diagnosis of subretinal fluid in the macula that could be diagnosed as central serous chorioretinopathy (CSCR). The authors have categorised them into 12 groups: neovascular diseases, vitelliform lesions, inflammatory diseases, ocular...

This is a review article characterising a clinical entity called paracentral acute middle maculopathy (PAMM). The article highlights the fact that retinal capillary plexuses are organised predominantly into three trilaminar capillary layers occupying the area between the nerve fibre layer...

Age-related macular degeneration, Choroidal neovascularisation type, Drusen load, Imaging biomarkers, Retinal layer volumes
This retrospective longitudinal study looked at patients with wet age-related macular degeneration (AMD) in one eye who subsequently developed wet AMD in the fellow eye. The aim was to discover whether drusen characteristics or volumes of retinal layers correlate with...

OCT, RNFL, Retinal nerve fiber layer, Spectralis, optical coherence tomography, signal strength
The aim of this study was to determine the effect of signal strength on mean retinal nerve fibre layer (RNFL) using spectralis optical coherence tomography (S-OCT). Thirty normal subjects were imaged with S-OCT using variably dense Bangerter foils to alter...
Conversion factors for fovea on / off detachments
This is a retrospective study of medical records in a single unit over a 14 year period from January 2001 – December 2014, of patients who converted from fovea-on to fovea-off rhegmatogenous retinal detachment (RRD). Ten cases were identified while...
Incidence and factors associated with complication of sutured and sutureless cataract surgery following PPV
This is a retrospective review of 485 patients who had undergone phacoemulsification and IOL implantation after previous pars planar victrectomy (PPV) surgery between May 2000 and May 2014. The incidence and factors contributing to complications were studied. The most common...

Glaucoma, Intraocular pressure, Resveratrol, Retina, Steroid-induced, Trabecular meshwork
Topical and systemic steroid delivery is a very effective treatment for many ocular conditions but is compromised by raised intraocular pressure which in turn leads to death of retinal ganglion cells and irreversible blindness. This is an important consideration with...
