Graves' Disease (GD) is a common cause of hyperthyroidism. Although definitive treatment with radioactive iodine (RAI) is preferred for military aircrew, there are cultural and individual differences in receptivity toward RAI, and clinical guidelines that recommend antithyroid drugs (ATD) as the first line therapy. We examined a case series of Republic of Singapore Air Force (RSAF) aviators with GD treated with ATD and the impact of their condition on aeromedical disposition.

Militaries around the world have been affected in many ways, in terms of force attrition and disruption to operations.
Materials And Methods: The Republic of Singapore Air Force (RSAF) had formulated multiple strategies and executed several contingency plans to respond swiftly and effectively to the pandemic.
This study sought to determine the incidence, severity, and time-course of simulator sickness (SS) among Asian military pilots following flight simulator training. A survey was conducted on Republic of Singapore Air Force pilots undergoing simulator training. Each subject completed a questionnaire immediately after (0H), and at the 3-h (3H) and 6-h (6H) marks.

The increased utility of CT coronary angiography (CTCA) in cardiovascular screenings of aircrew has led to the increased detection of asymptomatic coronary artery disease (CAD). A systematic review of studies relevant to the interpretation of CTCA for the occupational fitness assessment of high-risk vocations was performed, with findings used to describe the development of a pathway for the aeromedical disposition of military aviators with asymptomatic CAD. Medline was searched using the terms CT coronary angiogram and screening and prognosis.

This study was performed to test the hypothesis that refractive procedures, such as laser-assisted sub-epithelial keratectomy (LASEK) or small incision lenticule extraction (SMILE), may alter the range of PTA, within which refractive corneal surgery can be safely performed.
Setting: Refractive department, tertiary ophthalmic hospital.

Purpose: Due to the anatomical differences between the Asian and non-Asian eyelid, the authors hypothesize a different spectrum of eyelid margin malposition conditions seen in Singapore as compared with a predominant Caucasian population. The purpose of the study is to describe the spectrum of eyelid margin malpositions that were operated in a South-East Asian Tertiary Hospital.
Methods: Retrospective study involving all patients who required surgery for eyelid margin malpositions over a 2-year period.
