Predicting visual prognosis of patients with methanol poisoning
Symptoms of methanol poisoning often occur 12–24 hours after oral consumption, and visual symptoms are seen in approximately 50% of cases. This study aims to investigate the role of optic nerve diffusion status on cranio-orbital magnetic resonance imaging (MRI) in...
Diagnostic accuracy of enhanced depth imaging OCT in children
The authors present the findings of a retrospective cross-sectional case series. Cases were identified using a treatment register having been evaluated in a set one-year period. Two ophthalmologists acted as masked image examiners for enhanced depth imaging optical coherence tomography...The International Council of Ophthalmology: what is it and is it useful for UK ophthalmologists?
ICO Director for Examinations and Assessments, Simon Keightley, explains the history and role of the organisation today, as well as outlining recent changes to the ICO examinations. The International Council of Ophthalmology (ICO) is the only international medical specialty organisation...Cutting-edge practice in glaucoma care: what, how and why?
More effective treatments and drug delivery modalities, implantable minimally invasive glaucoma surgical (MIGS) devices, as well as accelerating clinical research programmes, will transform the surgical and clinical management of glaucoma in the near future. There is also an ever-greater emphasis...A near miss
A 55-year-old gentleman presented with a ‘blurry patch’ to his left eye which he had noticed for the past two months. The visual acuity with correction was 6/5 in the right eye and 6/6 in the left eye on the...
Retinoblastoma mortality associations with choroidal and optic nerve invasion
The authors present a retrospective cohort study. Data was extracted from the National Cancer Institute’s Surveillance Epidemiology and End Results (SEER) database, based in the US and founded in 1973. Cases of retinoblastoma were extracted using the inclusion criteria of...
Using modified staging criteria to determine optic nerve invasion in retinoblastoma
This paper reports the use of a modified staging criteria for optic nerve invasion in extraocular retinoblastoma and its correlation with treatment outcomes in 21 patients. The average age at presentation was 41 months (7–120) and there were 14 unilateral...
Retrograde maculopathy in glaucoma
Macular optical coherence tomography (OCT) analysis can be used for quantitative measures of optic nerve atrophy at a location far away from the optic nerve head. This has recently led to the discovery of microcystic macular oedema (MME), in the...
Visual prognosis in Irish Leber’s hereditary optic neuropathy
Leber’s hereditary optic neuropathy (LHON) is an inherited optic neuropathy This paper presents a retrospective review of clinical data from patients with LHON presenting to an Irish tertiary referral ophthalmic hospital. Clinical and genetic characteristics were assessed for useful biomarkers...The embryology of the eye
Nobody claims to like embryology. At least nobody I know. It has been a neglected part of the curriculum since time immemorial and a vicious cycle occurs in which those with an incomplete understanding fail to appreciate the inherent beauty...Principles of contact lens fitting in keratoconus
Keratoconus is an ectatic condition of the cornea characterised by progressive conical distortion with irregular astigmatism, myopia and apical protrusion. Most cases progress slowly resulting in varying degrees of myopic astigmatism. Management of keratoconus includes spectacles, soft contact lenses, a...
