Contrast sensitivity after laser corneal surgery

This study group compared contrast sensitivity among participants undergoing wavefront-guided or wavefront-optimised photorefractive keratectomy (PRK) or laser-assisted in situ keratomileusis (LASIK) for the treatment of myopia or myopic astigmatism 12 months after surgery. This was a prospective, randomised clinical trial,...

Sickle cell maculopathy

This paper reports the result of a prospective study to analyse the prevalence of sickle cell maculopathy (SCM) and its associations with age, sex, genotype, proliferative sickle cell retinopathy (PSR) stage, and the impact on visual acuity (VA). This study...

Exploiting nature’s randomised trials of eye disease

Confounding and reverse causation in observational ophthalmic epidemiology Traditional observational studies are inherently limited in establishing a causal effect of an exposure on an outcome of interest. One fundamental limitation is confounding, whereby causation is incorrectly attributed to a third...

Trabeculectomy for normal tension glaucoma

This is a retrospective consecutive, non-comparative case series of 131 eyes of 98 patients undergoing trabeculectomy between 2007 and 2013 in a normal tension glaucoma (NTG) clinic. Assessment of the clinical outcomes include intraocular pressures (IOP) reduction, bleb formation, final...

25 years of OCT

David Huang first described optical coherence tomography (OCT) in 1991, in his seminal paper on the subject in Science. This method developed the work of others on ophthalmic interferometry, which essentially showed that measuring reflected light could be used to...

Specialist high-street eye clinics for managing patients with retinal disorders can enhance care standards

The author examines the successful introduction of community-based retinal clinic services by Manchester University NHS Foundation Trust. Dr Sajjad Mahmood, Consultant Ophthalmologist, MREH, shares experience of establishing community-based medical retina clinic services.

Eyes on the road – visual standards for car drivers

The author examines the current visual standards required by drivers and asks whether more needs to be done to make roads safer. Are the public adequately protected by the current system of visual standards required by drivers? In a survey...

Open globe trauma – visual outcomes after primary vitrectomy

This retrospective study aimed to evaluate the impact of early vitrectomy on visual outcomes in eyes with open globe ocular trauma. One hundred and eighty eyes from a cohort of 166 patients who underwent primary vitrectomy between 2017 and 2023...

Unravelling ocular motility

Ocular motility can often be a slightly abstract concept during the earlier years of ophthalmology training. A large variance on what embodies normality; mythical concepts like fusion and binocular vision, examination techniques that can be fiddly, and complex neuroanatomy all...

Pituitary tumours: why are they so often missed?

Part 3: Clinical features, assessment and management (see also Part 2, and Part 1) As previously mentioned in this treatise [1] pituitary tumours are common, occur in all age groups and can present with anything from minimal visual symptoms to...

Relating metamorphopsia severity and OCT findings in advanced epiretinal membranes

The authors present the findings of a retrospective study to correlate metamorphopsia and ectopic inner foveal layers (EIFL) or ‘central bouquet’ abnormality (CBA) in patients with advanced stages of epiretinal membrane (ERM) following the new OCT‐based grading scheme as described...
