Using frequency doubling technology perimetry to identify Alzheimer’s disease early

Alzheimer’s disease is widely reported to be associated with deficits in visual function. Visual disturbances include impaired stereopsis, contrast sensitivity and motion detection. Deficits specific to the magnocellular pathway (MGC) have been identified in Alzheimer’s disease. This article compares the...

Antibiotic prophylaxis after intravitreal injections

The use of topical antibiotics as prophylaxis after intravitreal injections is a contentious issue, especially now with increasing use of intravitreal anti-VEGF agents. In the Wills Eye Institute, prior to May 2011, all patients undergoing intravitreal injections in the office...

Evaluation of keratometry with a novel colour LED corneal topographer

The Cassini topographer (i-Optics), which analyses corneal shape based on the reconstruction of specular reflections on 679 coloured LEDs, generates keratometry and is the new machine being compared in this study with other keratometry devices. The prospective comparative study included...

Swept-source OCT for measuring peripheral anterior synechiae

The authors report on a cross-sectional study looking at swept-source optical coherence tomography (SS-OCT) for measuring the area and degree of peripheral anterior synechiae (PAS) in patients with angle closure glaucoma. The SS-OCT is commercially available, has a laser wavelength...

Combined PRK and CXL in keratoconus

This study aimed to investigate the results after photorefractive keratectomy (PRK) followed immediately by standard 30-minute corneal cross-linking (CXL) for keratoconus. This retrospective study included 26 eyes of 16 patients with keratoconus. Uncorrected distance visual acuity (UDVA), corrected distance visual...

Review of pathogenesis of Acanthamoeba keratitis

In this review, the author summarised the current microbiomic and immunological evidence related to the pathogenesis of Acanthamoeba keratitis (AK). AK has been described for almost 50 years, but the exact biology of the disease remains perplexing. Acanthamoeba spp. are...

Fifteen-year results of phakic artisan IOL for hyperopia correction

This retrospective review of a cohort of 61 eyes from 32 patients offers long-term results for phakic Artisan (Ophtec BV) iris-fixated phakic IOL (IF-pIOL). The mean age at surgery was 41.6 years with a range of 25-59 years. Refractive outcomes...

Prevalence and risk factors for ROP in Saudi Arabia

This study aimed to establish the prevalence of retinopathy of prematurity (ROP) among high-risk neonates in a tertiary centre, identify the most commonly associated risk factors and highlight the benefits of early treatment of type 2 ROP and ROP milder...

Can coenzyme Q10 have a protective role in ethambutol-induced retinal ganglion cell toxicity

Tuberculosis (TB) is one of the most prevalent infectious diseases, especially in developing or low- income countries. Ethambutol is a widely used drug to treat TB. Ethambutol can cause visual disturbance including ethambutol toxic optic neuropathy (ETON). ETON is one...

Incomplete teprotumumab treatment for thyroid eye disease

The aim if this study was to report ophthalmic related findings and complications in children with facial palsy. Medical records from a tertiary centre were retrospectively searched for children 16 years and under with a diagnosis of facial palsy, over...

Is virtual reality perimetry as reliable as static perimetry in detecting neurological visual field loss?

This study compares agreement between virtual reality perimetry (VRP) and static automated perimetry (SAP) in a variety of neuro-ophthalmological conditions. For this work the Order of Magnitude (OM) VR-based visual field assessment system was used which has been developed by...
