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...
Update on primary angle closure glaucoma
This review article considers primary angle-closure glaucoma which is responsible for half of glaucoma-related blindness worldwide. Angle closure is characterised by appositional contact between the iris and trabecular meshwork. It tends to develop in eyes with shallow anterior chambers, anteriorly...
Investigating the effect of signal strength on mean retinal nerve fibre layer
The aim of this study was to determine the effect of signal strength on mean retinal nerve fibre layer (RNFL) using spectralis optical coherence tomography (S-OCT). Thirty normal subjects were imaged with S-OCT using variably dense Bangerter foils to alter...
Longitudinal findings in children with neurofibromatosis type 1
This retrospective chart review evaluates the ophthalmologic findings of children with neurofibromatosis type 1 (NF1). Optic pathway gliomas (OPGs) are the most common tumours found in children with NF1. Findings are compared between eyes with and without optic pathway gliomas...
