History An 18-month-old boy presented with a slow growing left anterior orbital lump medially. Examination revealed a palpable mass beneath the skin at the inferonasal aspect without any visual impairment. A CT scan (Figure 1) followed by an excisional biopsy...Intraocular lens technology to deliver enhanced optical performance after cataract refractive surgery
Modern cataract surgery aims to provide patients with the best possible visual outcome with the least dependence on spectacles and minimal or no complications and to treat both cataract and refractive errors with a single procedure. Phacoemulsification is the standard...Idiopathic intracranial hypertension (IIH)
IIH is a medical condition where the intracranial pressure (ICP) is raised without an obvious cause. The cerebrospinal fluid (CSF) is produced in by the choroid plexus in the lateral ventricles and the roof of the third and fourth ventricles,...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...Ophthalmic imaging in children
Ophthalmic imaging has in recent years become an integral part of the diagnosis and monitoring of patients. There is now a wide range of instruments available for imaging children and assisting in the provision of detailed clinical information for the...Chronic dacryocystitis?
Lacrimal drainage system tumours are rare and lymphomas account for less than 10% of these tumours [1]. Most patients presenting with lymphoma infiltration of the lacrimal drainage system have a history of previously diagnosed lymphoma elsewhere. We report a case...
Comparison of SS-OCT and SD-OCT in polypoidal choroidal vasculopathy
Swept source OCT (SS-OCT) is known to have a longer wavelength than spectral domain OCT (SD-OCT), allowing deeper penetration into retinal and choroidal layers. The aim of this study was to investigate whether SS-OCT is superior to SD-OCT in imaging...
Sex differences in the relationship between obesity and choroidal nevus in US adults
The National Health and Nutrition Examination Survey (NHANES); a population-based survey conducted annually in the US by the Centers for Disease Control and Prevention, was used to identify populations at higher risk for choroidal naevus. Over a period of four...
Management of diffuse OSSN with topical chemotherapy
Ocular surface squamous neoplasia (OSSN) can be localised to the conjunctiva or, less commonly, diffusely spread over the conjunctiva and cornea. Localised OSSN can be treated by surgical removal with adjuvant cryotherapy and chemotherapy with low rates of recurrence. Diffuse...
Aqueous humour cytokine levels in PCV and nAMD
This study looks into the possible roles of various cytokines or growth factors in the pathogenesis of exudative age-related macular degeneration (AMD) by comparing aqueous levels of 14 cytokines between eyes with polypoidal choroidal vasculopathy (PCV) and those with neovascular...
Atrophy and anti-VEGF
The aim of this study was to investigate treatment factors, along with ocular and systemic factors for their association with macular atrophy (MA) incidence in eyes with neovascular age-related macular degeneration (nAMD) treated with anti-VEGF aflibercept or ranibizumab according to...
