Management of diabetic macular oedema (DMO)

The authors present guidelines on current diagnostic and therapeutic procedures in the management of DMO. Fluorescein angiography (FA) and optical coherence tomography (OCT) are recommended before starting treatment to help diagnose and stage DMO, and can be repeated if there...

The natural history of treatment naïve choroidal neovascularisation (CNV) in geographic atrophy

The aim of this retrospective study is to assess the characteristics and natural history of quiescent CNV in geographic atrophy (GA) utilising multi-modal imaging. Case notes were reviewed of patients diagnosed with geographic atrophy between January 2010 and December 2016...

RPE tears after intravitreal Lucentis

The current hypothesis regarding retinal pigment epithelium (RPE) tears is the contraction and fibrosis in choroidal neovascularisation (CNV) tissue after anti-VEGF therapy can induce rips in the overlying RPE. This South Korean study aimed to identify the association between RPE...

Epiretinal membranes in uveitic macular oedema

Epiretinal membrane (ERM) formation in uveitic macular oedema is a fairly common structural complication of the retina. The authors describe a retrospective case series of 104 eyes of 77 patients with uveitic macular oedema from a tertiary centre. The treatment...

Retinal morphology after PASCAL PRP treatment

The authors of this prospective cohort study set out to report the changes on Spectral Domain-OCT of PASCAL panretinal laser photocoagulation (PRP) treatment for proliferative diabetic retinopathy (PDR) or severe nonproliferative DR (NPDR) and the retinal morphology, from one hour...

How does cataract surgery affect eyes with wet AMD?

In this retrospective cohort study the authors’ primary objective was to assess whether cataract surgery in eyes with wet age-related macular degeneration (AMD), triggered its progression. The surgical group comprised of 40 eyes versus 42 eyes in the non-surgical control...

Comparison of bilateral lateral and unilateral recession resection for IXT

This is a retrospective review study of patients between the ages of three and 15 years old with the basic type of intermittent exotropia (IXT) who had strabismus surgery between January 2003 to September 2009. There were 85 patients included...

RPE atrophy onset in treated nAMD

In this study the authors aim to evaluate the role of various factors for the development of retinal pigment epithelium (RPE) atrophy over a period of five years in patients with nAMD. Fifty-two newly diagnosed nAMD patients with complete absence...

Retinoschisis

In this retrospective study the authors evaluate the effect of pars plana vitrectomy (PPV) and internal limiting membrane (ILM) peeling for lamellar macular hole (LMH) with or without macular retinoschisis in highly myopic eyes. Twenty-one highly myopic patients (22 eyes)...

Intravitreal aflibercept for retinal angiomatous proliferation (RAP)

In this prospective study the authors present the visual and anatomical outcome of patients with RAP lesions who were treated with intravitreal aflibercept. The study cohort of 46 patients reached study completion at week 96. They were all Caucasians, with...

Retinal vascular occlusion from gentamicin injection post-vitrectomy

The authors present two case reports for the rare, but serious, complication of retinal vascular occlusion as a presumed result of subconjunctival injection following 25-gauge vitrectomy. Risk factors for the complication include: cardiovascular disease, retrobulbar anaesthesia, high intraocular pressure (IOP)...
