OCT angiography in PAMM secondary to CRVO

Paracentral acute middle maculopathy (PAMM) is a recently described manifestation presenting with hyperreflective bands within mid retina on spectral domain optical coherence tomography (SD OCT). The current view is that these findings are markers of ischaemia of deep retinal circulation....

Finasteride and central serous chorioretinopathy

The pathophysiology of central serous chorioretinopathy (CSC) is complex and has not been fully elucidated. Suggested theories include hyperpermeability and increased hydrostatic pressure in the choroidal vasculature, which creates RPE detachments overwhelming the RPE barrier function, leading to accumulation of...

HLA-B27 anterior uveitis

HLA-B27 has previously been shown to have an association with uveitis, ankylosing spondylitis, reactive arthritis, ulcerative colitis and psoriasis. The authors of this review provide an update of the epidemiology of HLA-B27 associated ocular disorders. There is great variation amongst...

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’...

OCT in peripheral corneal thinning

This small retrospective study used high resolution optical coherence tomography (OCT) Heidelberg Spectralis to identify features which could determine the underlying aetiology of peripheral corneal thinning. Ten patients were included; five with diagnoses of degenerative peripheral thinning; Terrien’s marginal degeneration...

Quarter DMEK

This case report describes a novel technique where one quarter of Descemet’s membrane (DM) was transplanted during a quarter-descemet membrane endothelial keratoplasty (DMEK) procedure. DMEK graft was prepared from a 58-year-old corneo-scleral donor after one week in culture. Peripheral DM...

Wrong intraocular lens events – what lessons have we learned?

Data from wrong IOL patient safety incidents (PSIs) submitted to the National Reporting and Learning System (2010–2014) were reviewed and scrutinised by thematic analysis and compared with the historical data collected for groups in 2003-2010, prior to the mandatory checklist...

Late stromal rejection in DALK

This case series reported on late stromal rejections in eyes after uncomplicated deep anterior lamellar keratoplasties (DALKs). Four eyes of three patients experienced episodes of isolated stromal rejection 33 to 46 months after surgically uncomplicated DALKs and a minimum of...

Scheimpflug images and graft rejection

This study aimed to assess corneal changes using 360-degree Scheimpflug images and pachymetry readings to outline screening parameters, which define graft rejection. Seventeen eyes of 16 patients developed clinically manifest allograft rejection two to 42 months after surgery – those...

Suspected vitreous seeding of uveal melanoma

This is a retrospective non-randomised study of 23 patients with consecutive uveal melanoma who underwent diagnostic vitrectomy between the period of January 2000 and November 2013. The reason for vitrectomy was suspected dissemination of tumour cells inside the eye. The...

Macular hole postop positioning

The purpose of this study was to determine whether the full thickness macular hole (FTMH) closure rate with nonsupine positioning (NSP) is noninferior to the high closure rate achievable with face down positioning (FDP). All patients were pseudophakic pre macular...

Intravitreal bevacizumab vs. triamcinolone in patients with DMO at the time of cataract surgery

This prospective, single masked randomised control trial (RCT) compared visual and anatomical outcomes when either intravitreal bevacizumab (BVB) or triamcinolone (TA) was administered at the time of cataract surgery and at subsequent review, if required, in patients with diabetic macula...
