‘Dysphotopsia’ describes an adverse effect from cataract surgery, which can either be categorised as ‘positive’ or ‘negative’.  Positive dysphotopsias refer to bright artefacts of light, often in the form of flashes, glares or haloes of light, which are most commonly located centrally or in the periphery. Conversely, negative dysphotopsias denote a temporal shadow, which is dark in character and typically arc-shaped (1). Despite not being an inflammatory or painful adverse effect of cataract surgery, dysphotopsias can be particularly bothersome to patients, and result in great anxiety and dissatisfaction post-operatively. Hence, this article aims to provide an insight into the epidemiology, pathophysiology, diagnosis and management of negative dysphotopsia to aid the clinician in counselling on this side effect pre-operatively and managing it if required.

Eye care is a vital yet often under-prioritised aspect of managing unconscious or sedated patients in the Intensive Care Unit (ICU). Without appropriate precautions, patients are at risk of serious ophthalmic complications that may lead to long-term vision impairment or permanent blindness. This article outlines the best practices for eye assessment and protection, highlights common ICU-related ocular conditions, and provides recommendations for prevention, treatment, and when to seek ophthalmology input.

Posterior capsule rupture (PCR) is a well-recognised complication of cataract surgery and a key quality indicator in ophthalmic surgical outcomes (1). Conducting an audit on PCR is not only a valuable exercise in clinical governance but also relatively straightforward, making it an excellent opportunity for both ophthalmology trainees and those applying for training to gain audit experience and contribute to improving patient safety.

Corticosteroids can induce ocular hypertension and a type of secondary open-angle glaucoma, referred to as steroid-induced glaucoma. The use of corticosteroids is widespread and readily prescribed in clinical practice, and they have adverse effects on ocular health when used for long periods or in high doses; thus, it is important for clinicians to understand how to prevent vision-threatening complications in patients on corticosteroid therapy. This article will discuss the pathophysiology of steroid-induced glaucoma, associated risk factors, methods of diagnosing, and management, so that the clinician is somewhat familiar with the condition before diagnosing, managing, or even preventing it in patients.

Envision yourself in a hypothetical future where you are 87 years old and residing in Geneva, Switzerland, after having led a healthy life. As you relax on your sofa one afternoon, you notice something peculiar. There is a white handkerchief with four orange circles floating in the air. This sight leaves you momentarily frightened and bewildered. How could a handkerchief be floating in space? Where did it come from, and how did it get there? You may experience a range of emotions in this scenario. Initially, you might feel compelled to call out for help, but then you might hesitate, concerned about what others might think. The fear of being misunderstood or labelled as crazy could make you feel alone and confused, even though you know that you're the same person you've always been, with the same thoughts and feelings. The only thing that has changed is the presence of this unexpected handkerchief. This situation could trigger a sense of worry and isolation, which could be difficult to navigate

Tertiary eye casualty departments in the United Kingdom are often inundated with high volumes of patients from broad catchment areas. Patients may self-present during opening hours, arrive after being signposted from local or regional accident and emergency departments, referred by optometrists and general practitioners, or sent from smaller neighbouring ophthalmic departments. This constant inflow can overwhelm the system to breaking point, causing significant delays and leaving patients and staff extremely frustrated.

Vision is inarguably the most vital sense, enabling individuals to navigate the world, connect with others, and experience life in vivid detail. At the forefront of maintaining clear vision is the cornea, the transparent, dome-shaped outer layer of the eye that focuses light onto the retina. However, injury, infection, or diseases such as keratoconus and corneal dystrophies can compromise its clarity, leading to significant visual impairment or blindness. For millions of people worldwide, corneal transplantation has offered a lifeline, restoring sight and improving quality of life. This remarkable procedure, first performed successfully over a century ago, has transformed from a rudimentary surgical endeavour into a sophisticated intervention supported by advances in technology, immunology, and bioengineering. As we look to the future, corneal transplantation continues to evolve, offering innovative solutions to the challenges of donor shortages, surgical precision, and accessibility. This article will explore a brief history, current techniques and future advancement in corneal transplantation.

The 21st century has seen a sharp rise in the use of non-surgical cosmetic procedures, such as dermal fillers and botox injections. Their immense popularity can be attributed to their promise of facial rejuvenation, ease of access, and minimal downtime. However, as their use has surged, so too have their complications. Given the delicate neurovascular anatomy surrounding the eye, improper injection techniques or product migration have led to serious adverse effects including vision loss, diplopia, and ptosis. This article aims to highlight some key ophthalmic risks associated with cosmetic procedures and consequently highlight the importance of awareness and preventative strategies.

Keratoconus is a progressive corneal disorder characterised by thinning and conical shape of the cornea, posing a significant impact to ophthalmology physicians and patients’ quality of life. Patients are affected from a young age with various habitual, genetic, and environmental factors including eye rubbing, previous family history, as well as conditions such as Down Syndrome. Visual acuity is impacted through severe astigmatism, corneal scarring, and even corneal perforation with a prevalence of up to 5% of the population, especially in regions such as the Middle East.
