Diagnostic error rates for ROP detection by trainee ophthalmologists

The purpose of this study was to characterise common errors in ROP diagnosis by ophthalmologists-in-training in the USA and Canada. Case acquisition was from a web-based system used for ROP assessment from which 20 cases were selected. Fifty-five trainees from...

Diagnosis and management of paediatric keratoconus

This article reviews the current literature on paediatric keratoconus diagnosis and management. Paediatric cases pose challenges as they may not vocalise unilateral changes, difficulty in obtaining reliable imaging, faster rates of progression, difficultly with contact lenses and presumed worse outcomes...

Surgical treatment outcomes and predictors for consecutive exotropia

This retrospective study presented the long-term results of consecutive exotropia surgery and its prognostic factors, and compared efficacy of medial rectus advancement, lateral rectus recession, or a combination of both. Patients were treated between 2000–2020. Mean age was 33.98 ±17.68...

Macular pigment in relatives of AMD patients

Blue light causes photo-oxidative retinal injury and macular pigment (MP), with lutein, zeaxanthin and mesozeaxanthin as the main components, as a filter that protects the macula from this damage. Previous studies indicated that low levels of macular pigment optical density...

Prismatic contact lens correction vs prismatic glasses

The aim of this study was to verify if diplopia could be corrected by applying soft directional prism contact lenses, to compare effectiveness of diplopia correction, comfort and quality of vision with these contact lenses compared to prism glasses. This...

Clinical predictors of proliferative sickle cell retinopathy

Sickle Cell Disease (SCD) is an inherited disorder resulting in production of Haemoglobin S (HbS), which aggregates in conditions of hypoxia, acidosis or hyperosmolarity. This leads to vascular stasis, thrombosis and ischaemia. The authors present a cross-sectional study (45 consecutive...

Intermittent manual compression for CCF

Carotid cavernous fistulae (CCF) can be classified as high and low-flow or as having direct and indirect communication. Most commonly, management of high-flow CCF is with endovascular embolisation. The authors look at an alternative treatment for CCF in indirect low-flow...

Comparison of five IOL formula for paediatric eyes

There is no consensus on the most suitable intraocular lens formulas for paediatric eyes to provide consistent postoperative results. This study compared modern IOL formulas to identify the smallest mean prediction error among them: Hill-RBF 2.0, Barrett Universal II (BUII),...

Is thrombolytic treatment warranted for central retinal artery occlusion?

Central retinal artery occlusion (CRAO) is a subtype of acute ischaemic stroke which results in severe visual loss. Acute CRAO is equivalent to a brain acute ischaemic stroke (AIS), as the obstruction of the central retinal artery (CRA) causes end-organ...

Review of chalazion treatment

Even though chalazion is a common eyelid lesion, there is lack of consensus on a treatment algorithm. Conservative management includes lid hygiene and warm compresses and, in some cases, steroid ointments for two to three weeks. More invasive options for...

Retrobulbar amphotericin B for rhino-orbital-cerebral mucormycosis

Rhino-orbital-cerebral mucormycosis (ROCM) is a rare and often fatal infection usually occurring in immunocompromised patients from diseases such as diabetes, haematological malignancy and solid organ transplantation. Current standards of care include systemic antifungal therapy and debridement, including exenteration. This study...

Comparison of bupivacaine injection vs. mini-tenotomy for small angle deviations

Bupivacaine hydrochloride is an aminoacyltype local anaesthetic. Injection into extraocular muscles elicits a myotoxic response destroying striated muscle fibres but sparing satellite cells, nerves and vessels. Preserved satellite cells proliferate to form new muscle fibres, causing muscle hypertrophy and greater...
