Managing idiopathic intracranial hypertension in the eye clinic.

Idiopathic intracranial hypertension (IIH) is a neuro-ophthalmological condition characterised by a raised intracranial pressure and papilloedema that causes disabling headaches. The main risk factors of female sex and living with obesity have been known for some time, however the knowledge of the underlying pathophysiology is evolving. Papilloedema can impact the visual function, and the majority of people are offered acetazolamide. Those with sight threatening disease need urgent management, though there is little high quality evidence to recommend any particular surgical intervention. Headache treatment is an unmet clinical need and simple medication overuse advice has the potential to reduce the chronification of migraine-like headaches. IIH is emerging as a systemic metabolic disease distinct from people living with obesity alone. While weight loss is the main stay of disease modifying therapy this is challenging to access and many healthcare professionals that manage the condition have no formal training or accessible pathways for weight management. The aim of this "how to do it" article is to present the latest advances in knowledge of IIH that we pragmatically included in routine clinical care for people living with the condition.

Risk factors and disease associations in people living with idiopathic intracranial hypertension.

INTRODUCTION: Idiopathic intracranial hypertension is a neurological condition characterized by a raised intracranial pressure and papilledema, leading to chronic headaches and visual disturbances. By recognizing modifiable risk factors and deploying evidence-based interventions, healthcare providers have the potential to mitigate the burden of the disease and improve patient outcomes. AREAS COVERED: It is well known that the condition occurs in predominantly pre-menopausal females who live with obesity particularly in the context of recent weight gain. This review discusses what risk factors may contribute to the metabolic underpinnings of cerebrospinal fluid dysregulation. There are a number of disease associations that are important to screen for as they can alter management. EXPERT OPINION: There is emerging evidence to suggest that idiopathic intracranial hypertension is a systemic metabolic disease and it is unknown what are all the risk factors are that precipitate the condition. Targeting certain hardwired risk factors is unachievable. However, as recent weight gain has been identified as a predominant risk factor for the development of the disease and relapse, modification of body weight should be the primary aim of management. Insightful research into the involvement of the neuroendocrine axis driving cerebrospinal fluid dysregulation now has the potential for the development of therapeutic targets.

Impact of the eye clinic liaison officer at an NHS foundation trust: a retrospective study.

OBJECTIVE: Vision loss has a significant impact on physical, mental and social well-being. Eye clinic liaison officers (ECLOs) have a crucial role in providing holistic care for patients with visual impairment. The aim of this study was to review the work of an ECLO over a period of 1 year at an NHS Trust to determine the volume of work and the areas of support provided by the ECLO. METHODS AND ANALYSIS: A secondary data analysis of the ECLO case notes for all patients reviewed by the ECLO at University Hospitals Birmingham (UHB) NHS Trust during the year 2019, was performed. Demographic data and certification of visual impairment (CVI) status were noted. The main outcome variable recorded was the categories of support provided by the ECLO. Case vignettes were chosen to illustrate the variety of support offered to individual patients. RESULTS: A total of 1127 consecutive participants were reviewed by the ECLO at University Hospitals Birmingham (UHB) NHS Trust during the year 2019. Areas of support most commonly provided by the ECLO included aiding the process of registration for CVI, and assistance in accessing benefits, social support and low vision support. Severely sight impaired patients required significantly more areas of support than sight impaired patients (Χ2=52.7, p=2.16×10-6). Three case vignettes, chosen by the ECLO, highlighted the positive impact of the ECLO with respect to emotional support, practical advice and as a point of contact ensuring continuity of care, also during the COVID-19 pandemic. CONCLUSIONS: The ECLO at UHB NHS Trust provides a core patient service within the ophthalmology department by being a key source of practical and emotional support and the crucial link between healthcare, social care and voluntary services.
