Association between colour vision impairment and amyotrophic lateral sclerosis (ALS)

The purpose of this study is to test the hypothesis that colour vision impairment is associated with amyotrophic lateral sclerosis (ALS). Abnormalities of the inner and intermediate retinal structures in patients with ALS have been described using optical coherence tomography...

Biomechanical stabilisation of ocular measurements post cataract surgery

This prospective study looks into the time duration of biomechanical stabilisation post uneventful cataract surgery in a case series of 62 consecutive eyes in patients with no ocular or systemic comorbidity. The patients were followed-up at fixed intervals of one...

Outcomes of paediatric cataract

The authors aimed to compare the visual outcomes of primary and secondary IOL implantation and to identify the risk factors for the development of strabismus in patients with paediatric cataract. The study included 220 eyes of 148 patients: 76 unilateral...

AOP update on new GOC e-service for statutory notices

The GOC intends to introduce email communication for statutory notices with consent.

Combined ranibizumab and ablative therapy for Coat’s disease

The aim of this study was to observe the efficacy of intravitreal ranibizumab (IVR) combined with laser photocoagulation or cryotherapy, for Coats’ disease. Patients younger than 16 years of age who were diagnosed with Coats’ disease were included in this...

Using OCT to screen and monitor Alzheimer’s disease

Alzheimer’s disease (AD) is a neurodegenerative illness characterised by progressive decline in cognitive function. AD is the main cause of dementia worldwide. Over recent years researchers have strived to find biomarkers to diagnose AD, particularly in the early stages of...

The London Crisis at Christmas Opticians and Eyecare Service, which is run as a partnership between Crisis, the national charity for people experiencing homelessness and Vision Care for Homeless People, celebrated its 20th year in December, with the service growing from one initial clinic to nine in London.

Prophylaxis for clinical macular oedema after phacoemulsification

The authors report on a retrospective cohort study looking at three different prophylaxis methods for macular oedema after cataract surgery: 1) Topical prednisolone acetate (PA) alone; 2) Topical PA in combination with non-steroidal anti-inflammatory drug (NSAID); 3) Intraoperative subconjunctival injection...

DALK as an early therapeutic option for Acanthamoeba keratitis

Eleven patients with Acanthamoeba keratitis (AK) were treated by early therapeutic deep anterior lamellar keratoplasty (DALK). All surgeries were performed in patients who had no response to standard medical therapy of chlorhexidine gluconate, propamidine isethionate and neomycin sulphate, within 10-15...

Retinal nerve fibre layer thickness in migraine

The aim of this study is to evaluate retinal nerve fibre layer (RNFL) thickness changes in children with migraine compared to healthy controls and analyse RNFL changes dependent on type of migraine. This was an observation case control study of...

A review of neuro and retinal imaging findings in Alzheimer’s disease

The authors present a systematic review with the aim of assessing the relationship between retinal and cerebral changes in Alzheimer’s disease (AD), mild cognitive impairment and pre-clinical AD. A total of 23 articles met the inclusion criteria of the review,...

Nicotine accelerates diabetes induced retinal changes

This study investigated the influence of nicotine in an experimentally induced diabetic rat model. They used non-invasive high-resolution spectral domain optical coherence tomography (SD-OCT) imaging to provide quantitative information on the temporal alterations of retinal structures at the micrometer resolution...
