Presentation of Orbital Metastases.

Purpose: To compare clinical characteristics of patients with and without a known systemic malignancy at the time of diagnosis of orbital metastases.

Methods: Retrospective case note and imaging review for patients with orbital metastases presenting between 1980 and 2022. Patients were classified as having known malignancy at orbital presentation (group I) or without known malignancy (group II).

A novel training session: mixed reality evisceration surgery webinar.

Background: Evisceration surgery is an important part of an ophthalmologist's skillset but is an uncommon procedure. Therefore, it is important for training ophthalmologists to have adequate knowledge and confidence in this procedure to maximise learning opportunities. Mixed reality involves the intertwining of real and virtual environments and has been used successfully in surgical training.

Autologous anterior lens capsule flap and serum transplant in managing idiopathic and refractory full-thickness macular holes.

Purpose: To report the results of pars plana vitrectomy (PPV) with inner limiting membrane (ILM) peeling alongside phacoemulsification and intraocular lens (IOL) implantation with autologous anterior lens capsule flap (ALCF) and autologous serum transplantation (AST) into full-thickness macular holes (FTMH) and 14% perfluoropropane (C3F8) tamponade for idiopathic and refractory FTMHs.

Methods: Retrospective study involving eleven patients with idiopathic FMTHs and seven with refractory FMTHs after standard surgery with PPV, ILM peeling, and gas tamponade. All eyes underwent a 'combination procedure' of PPV with ILM peeling alongside phacoemulsification and IOL implantation with autologous ALCF and AST into the FTMH and 14% C3F8 tamponade.

Primary lacrimal sac melanoma: a case report describing the novel use of fine needle aspiration cytology (FNAC) for diagnosis, together with literature review and immunotherapy treatment update.

Primary lacrimal sac melanoma (PLSM) is exceedingly rare and associated with high morbidity and mortality. Unfortunately, PLSM often presents insidiously resulting in delayed detection and poor prognosis. A 69-year-old Black man was suspected of having a lacrimal sac tumour following presentation with a left sided watery eye, bloody tears, and a lacrimal mass.

Myopic macular hole detachment associated with intravitreal ocriplasmin.

Purpose: To describe a case of macular hole retinal detachment in a high myope following intravitreal ocriplasmin injection.

Observations: A 71-year-old highly myopic (-18.63 Dioptres) female received 125 μg of intravitreal ocriplasmin (Jetrea, Oxurion, Leuven, Belgium) to treat a right, full-thickness macular hole (FTMH) with vitreomacular adhesion.

Real-world incidence of fingolimod-associated macular oedema.

Background: Fingolimod (Gilenya, Novartis, Basel Switzerland) 0.5 mg orally once-daily is widely used for relapsing-remitting multiple sclerosis. Patients are usually screened four months after starting fingolimod for fingolimod-associated macular oedema (FAME).

A double Descemet's stripping endothelial keratoplasty on a penetrating keratoplasty.

A patient with keratoconus underwent a penetrating keratoplasty (PK) in his right eye. This failed after 12 years following phacoemulsification surgery. A Descemet's stripping endothelial keratoplasty (DSEK) was carried out which failed and detached after 4 months.

Posterior Segment Distortion in Ultra-Widefield Imaging Compared to Conventional Modalities.

Background And Objectives: To describe posterior segment distortions in Optos ultra-widefield images (Optos 200TX; Optos, Dunfermline, United Kingdom) compared to Topcon retinal camera images (Topcon, Tokyo, Japan) using optic disc dimensions and exploring a proposed method for correcting these distortions.

Patients And Methods: Comparative image analysis study on 20 eyes with color fundus images from Optos and Topcon. A model eye with vertical and horizontal grids imaged with Optos in the conventional position and rotated 90° was analyzed.

The association of exposure to hepatitis B and C viruses with lung function and respiratory disease: a population based study from the NHANES III database.

Background: Globally, 500 million people are chronically infected with Hepatitis B virus (HBV) and Hepatitis C virus (HCV). While these viruses are notorious for their detrimental effect on the liver they are also known to affect multiple organs in the body including the lungs.

Aim: To investigate if exposure to HBV and HCV is associated with lung function and respiratory diseases.

Observations on the epidemiology of gastrointestinal and liver cancers in the Asia-Pacific region.

Gastric cancer (GC) has long been thought to be an Asian type of cancer that is broadly associated with poverty, whereas colorectal cancer (CRC) has been thought to be a Western type of cancer associated with affluence. The incidence of GC has declined dramatically in the West but has a very high incidence in East Asia. The age-standardized incidence rates (ASR) have also declined.

Obesity: an epidemiological perspective from Asia and its relationship to gastrointestinal and liver cancers.

Obesity is major health problem in the Asia-Pacific region. The proportion of people who are overweight and obese in the region has increased dramatically and is closely linked to the increasing affluence in the region. While the body mass index has been used as a yardstick in many published studies, it has been noted that Asian patients have a greater percentage body fat for a given body mass index and especially abdominal or visceral obesity.
