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...
Migraine attack: does retinal and peripapillary blood flow change?
This prospective clinical study compared retinal and peripapillary blood flow parameters in migraine patients during an attack with healthy controls using optical coherence tomography angiography (OCTA). OCTAs were performed on 52 eyes from 26 migraine sufferers and 48 eyes from...
OCTA in angioid streaks
This paper reports on the optical coherence tomography angiography (OCTA) features of choroidal neovascularisation (CNV) secondary to angioid streaks and the ability to predict CNV activity. A total of 38 eyes of 19 patients were included in the study. Thirty...
OCT angiography findings in amblyopic eyes
In this study, optical coherence tomography angiography (OCTA) was used to detect the existence of any vascular dysfunction in superficial and deep retinal layers that accompany visual impairment in amblyopic eyes compared to fellow and control eyes. The study included...
Migraine and risk of retinal artery occlusion
This retrospective cohort study assessed whether migraine was associated with an increased risk of retinal artery occlusion. They reviewed a large insurance database of 418,965 patients who suffered with migraines between 2007 and 2016. These were then matched with an...
Is an increased homocysteine level associated with greater risk of AMD?
Basic research studies have implicated homocysteine in causing vascular endothelial dysfunction and inflammation, and this has been borne out in large observational studies which suggested that elevated homocysteine is associated with increased risk of cardiovascular disease. In order to determine...
Choroidal and macular thickness in nonarteritic anterior ischaemic optic neuropathy
This study evaluates the choroidal and macular thickness in patients with chronic nonarteritic anterior ischaemic optic neuropathy (NA-AION). Two groups of subjects were compared, group one included 20 eyes with chronic NA-AION and group two, 31 healthy control eyes. The...Retinal arteriovenous malformation
A 24-year-old Caucasian girl reported to the eye clinic with the complaint of painless decreased vision in her right eye. She had no history of infectious disease, trauma, systemic malignancy or other systemic complaint. Her best corrected visual acuity was...
Stereotactic radiotherapy for polypoidal choroidal vasculopathy
Polypoidal choroidal vasculopathy (PCV) is a variant of neovascular AMD. It is a disease of choroidal vasculature characterised by abnormal branching vascular network with aneurysmal dilatations (polyps). Features of PCV include pigment epithelial detachments (PED), subretinal fluid (SRF) accumulation and...
Ginko bilboa extract affects hypoxic retinal pigment epithelial cells
Wet age-related macular degeneration (AMD) is characterised by choroidal neovascular membrane (CNVM) formation. It is thought that localised hypoxia within the retina results in overexpression of growth factors such as vascular endothelial growth factor (VEGF), which induces CNVM formation. VEGF...
