ARN in North Africa

Acute retinal necrosis (ARN) is a rare cause of uveitis. This paper aims to outline the clinical features of 12 patients with ARN in a referral centre in Tunisia, North Africa. A retrospective review of case notes was carried out....

Transfected RPE cells inhibit AMD in rats

Age-related macular degeneration (AMD) is a leading cause of blindness in the elderly. Wet AMD is characterised by choroidal neovascularisation, new vessels into the retina, leading to leakage and tissue damage. Many proangiogenic factors particularly vascular endothelial growth factor (VEGF)...

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...

Meta-analysis of HLA B27 associated acute anterior uveitis

A literature-based meta-analysis was carried out to look at the various clinical features associated with HLA- B27 acute anterior uveitis (AAU). After an extensive search of literature for HLA B27 uveitis was conducted, 735 results were obtained. Twenty-nine articles were...

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...

Sclerotomy suturing

This was a retrospective review of 589 consecutive cases of patients who underwent 23-gauge tranconjunctival pars plana vitrectomy. Cases were split into Type 1 vitrectomies (macular hole, ERM and simple vitreous haemorrhages) and Type 2 cases which were more complex...

Sutureless 27-gauge needle intrascleral intraocular lens implantation

The authors report on a prospective, non-comparative, interventional case series of patients undergoing sutureless intrascleral fixation of a posterior chamber three piece intraocular lens (IOL) using a 27-gauge needle for docking. Sutureless techniques have the advantage of not having complex...

Prostaglandin levels in femto cataract surgery

Following previous reports of pupil size decrease after femtosecond treatment, the authors compare levels of prostaglandins in patients undergoing femtosecond assisted cataract surgery with those having routine cataract surgery. Patients with inflammatory eye disease, previous trauma surgery, age-related macular degeneration...

Does Ozurdex affect perfusion status in vein occlusion?

Ozurdex (intravitreal dexamethasone implant) has been approved by National Institute of Health & Care Excellence (NICE) for treatment of patients with macular oedema associated with vein occlusion. This study looks at the change in peripheral perfusion status in patients with...

Cataract surgery in patients with retinitis pigmentosa

Retinitis pigmentosa (RP) is the commonest inherited cause of retinal degeneration. Posterior subcapsular cataract (PSC) develops in 41% to 90% of these patients by age 40 years. In this retrospective study, the authors have evaluated surgical outcomes in patients with...

Injection of methotrexate into silicone oil-filled eyes for grade C PVR

Methotrexate (MTX) is an antineoplastic antimetabolite with immunosuppressant properties. Folate antagonism is known to contribute to the antiproliferative effects of MTX, and release of adenosine from cells and inhibition of polyamines may explain its anti-inflammatory effects. These activities contribute to...

Near-infrared autofluorescence to diagnose retinal laser injuries

This retrospective observational case series aimed to assess whether near infrared autofluorescence (NIR-AR) imaging is a useful imaging modality in the diagnosis of hand-held laser retinal injuries. Twelve patients from two centres underwent ophthalmic assessment and retinal imaging including fundus...
