RPE use similar pathway to regulatory T cells to inhibit immune response

Retinal pigment epithelial (RPE) cells form an important part of the blood-retinal barrier that protects the neuronal cells responsible for sight. RPE cells are involved in innate and adaptive immune responses via expression of surface molecules and release of cytokines....

Polymerase chain reaction evaluation of infectious multifocal serpiginoid choroiditis

This paper presents a retrospective review of infectious agents associated with multifocal serpiginous choroiditis (MSC) based on polymerase chain reaction (PCR) evaluation and specific antimicrobial therapy. The study included 13 patients with MSC who were evaluated with PCR for the...

Role of fundus autofluorescence patterns and baseline atrophy area on geographic atrophy progression

Central geographic atrophy (GA) is one of the morphological sub types of late-stage macular degeneration. The natural course of the disease is characterised by expanding areas of macular atrophy, which cause absolute scotoma. Fundus autofluorescence (FAF) is derived from lipofuscin...

Intravitreal functional plasminogen in branch retinal vein occlusion

Branch retinal vein occlusion (BRVO) is the second most common vascular disorder of the eye. Intravitreal injections of anti-VEGF agents and corticosteroids have proven efficacy. Posterior vitreous cortex (PVC) adhesion has been shown to support the development of retinal vein...

Efficacy of intravitreal dexamethasone implant in patients with persistent macular oedema

Chronic cystoid macular oedema (CME) can develop secondary to various pathologies such as diabetic maculopathy, retinal vein occlusion and uveitis. It can cause significant visual impairment and macular damage. The therapeutic effect of corticosteroids in CME is through one or...

Effect of voriconazole of vision of healthy volunteers

Voriconazole is a broad spectrum, triazole antifungal agent used for systemic fungal infections. It has a favourable safety profile and is available in both intravenous and oral forms. The commonest adverse drug reactions with voriconazole are changes in visual perception,...

Visual acuity after cataract surgery in AMD patients

The data from this study are obtained from the Age-Related Eye Disease Study (AREDS) 2 and analysed to evaluate if cataract surgery benefits patients with concurrent age-related macular degeneration (AMD). The AREDS 2 was a five year, prospective, multi-centre randomised...

Intraoperative floppy iris syndrome and prevalence of intraoperative complications

Alpha-blockers (particularly of the selective type) are known to be associated with intraoperative floppy iris (IFIS) and poor dilation, which can present in various severities during cataract surgery and need to be recognised in order to avoid intraoperative complications. Methods...

Anterior and posterior capsular opacification with the Tecnis ZCBOO and AcrySof SA60AT IOL

This a randomised, controlled, prospective and double-blind study comparing the anterior capsular opacification (ACO) and posterior capsular opacification (PCO) outcomes with two types of single-piece hydrophobic acrylic intraocular lenses (IOL), and AcrySof SA60AT – Group A, and Tecnis ZCBOO –...

LASEK vs. epi-LASIK for myopia: meta-analysis

Previous studies have produced inconsistent conclusions on the relative benefits between LASEK vs. Epi-LASIK. LASEK uses 20% alcohol to separate an epithelial flap from the Bowman membrane. After ablation, the epithelial flap is repositioned onto the cornea. Epi-LASIK creates the...

Inhibiting high-risk corneal allografts

The cornea is an immune privileged site and as such corneal transplants are very successful. However, in situations where this privilege is lost the failure rises substantially. To combat rejection inhibition of the immune responses depends on steroids and other...

Effect of preservative free fluoroquinolones on human corneal epithelial cells in vitro

Fluoroquinolones, including second generation (ofloxacin and ciprofloxacin), third generation (levofloxacin and tosufloxacin) and fourth generation (gatifloxacin and moxifloxacin), are a group of bactericidal agents used to treat multiple ocular infections. The third and fourth generation fluoroquinolones have enhanced Gram-positive activity...
