Stereopsis changes with cataract
Stereoacuity was compared preoperatively to six weeks postoperative after cataract extraction and intraocular lens (IOL) implant. The authors evaluated the association of postoperative stereoacuity with visual acuity, age and duration of preoperative symptoms. This prospective study recruited 142 patients: 92...
Literature review of OKN
The authors conducted a critical review of the optokinetic nystagmus (OKN) literature to consider OKN and in particular, vertical OKN. The review provides an overview of OKN to aid understanding of the eye movements. It provides a review of the...Ambitions for sustainable service recovery amidst an escalating post-COVID backlog
Rod McNeil reviews plans, activity and solutions to better address the post-COVID backlog and bolster sustainable service recovery. Ophthalmology was the busiest outpatient specialty during the three years to March 2020 across the English NHS and again recorded the highest...How good does my vision have to be to drive this thing? Visual standards for various occupations
We can all picture that moment in clinic: you are about to tell someone that they’re no longer legally able to drive, ready to deploy our ‘breaking bad news’ techniques. For some patients this may have been expected, or they...
Topography-guided photorefractive keratectomy in the treatment of corneal scarring
This study reports the outcome of topography-guided photorefractive keratectomy (TG-PRK) in the treatment of patients with corneal scarring. A retrospective case series including six eyes of six patients with corneal scarring and irregular astigmatism who underwent topography guided PRK. The...
Outcomes of cataract surgery in patients with uveitis
This is a systematic, evidence-based literature review and meta-analysis, looking at the visual outcomes (vision 20/40 or better) of cataract surgery in uveitic eyes. The authors searched MEDLINE, EMBASE, CINHAL and CENTRAL, including English language and human studies only. They...
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...
PERG as a visual prognosticator in chiasmatic tumours
Pattern electroretinogram (PERG) allows assessment of ganglion cell function and may therefore be used to assess anterior visual pathway dysfunction. This prospective non-randomised study assessed PERG before and after surgical removal of tumours in and around the sellar region compressing...
Macular thickness and visual fields
The authors describe a comparison of spectral domain OCT with Humphrey visual fields (HVF) mean deviation (MD) and pattern standard deviation (PSD), examining the retinal thickness of the macula and circumpapillary retinal nerve fibre layer (RNFL) defects. Seventy-three subjects who...
CHARGE syndrome features
CHARGE syndrome (CS) includes coloboma, heart defects, atresia of the choanae, retardation of growth and development, genital and urinary anomalies and ear anomalies. The authors developed an original self-administered questionnaire (VISIOcharge) for patients with CS and used it to evaluate...
Sub-clinical detection methods in multiple sclerosis
Visually symptomatic multiple sclerosis (MS) provides only part of the required information to assist in understanding the disease. Recently, researchers have concentrated their efforts on diagnosing MS cases in the subclinical period. The aim of this paper was to assess...
