Optical coherence tomography angiography usability in measuring iris vasculature in strabismus surgery
The purpose of this study was to investigate the use of optical coherence tomography angiography (OCTA) as a screening tool for anterior segment ischemia (ASI) in strabismus surgery. Optical coherence tomography angiography measurements were taken in 18 subjects. Twelve were...It’s not always GCA
Giant cell arteritis (GCA) is an immune mediated granulomatous inflammatory disease that affects muscular middle or large sized arteries. It is considered as a continuation of polymyalgia rheumatica (PMR) when the severity of the disease has increased. It is the...A near miss
A 55-year-old gentleman presented with a ‘blurry patch’ to his left eye which he had noticed for the past two months. The visual acuity with correction was 6/5 in the right eye and 6/6 in the left eye on the...Non-arteritic anterior ischaemic optic neuropathy in the Asian population

Anterior ischaemic optic neuropathy, inflammation, monocyte to high-density lipoprotein ratio
The authors evaluate the monocyte to high-density lipoprotein (HDL) ratio (MHR) in patients with arteritic and non arteritic anterior ischaemic optic neuropathy (A-AION / NA-AION). A distinction between the two types of AION is essential to begin appropriate treatment, which...

Non-arteritic anterior ischaemic optic neuropathy, NAION, severe visual loss, visual acuity
Very severe visual loss (hand movements or less) is typical of arteritic anterior ischaemic optic neuropathy (AION) and relatively rare in non-arteritic AION (NAION). This study aimed to report the frequency of very poor visual acuity (VA) in NAION. The...
