Biopsy of nasolacrimal duct using sheath guided dacryoendoscopy
In this study the author’s biopsied six eyes of five individuals with recurrent nasolacrimal duct obstruction following a prior dacryoendoscopic probing. All procedures were performed under local anaesthetic, the obstruction or lesion was directly visualised with dacryoendoscope and biopsy was...
Intraocular pressure reduction after cataract surgery
Several studies have shown the efficacy of cataract surgery in lowering intraocular pressure (IOP), especially in angle closure glaucoma compared to open angle. A total of 156 eyes of 109 patients (without glaucoma or with medically controlled glaucoma) were included....
Retinal vessel diameter in pseudoexfoliation
Pseudoexfolation (PEX) is characterised by deposition of fibrillary extracellular material on ocular and extraocular tissue. Studies have shown that deposition in vascular structures cause hypoxia and ischaemia. In the eye, a decrease in blood supply to the optic nerve can...
A robotic armrest for ophthalmic surgery
Robot-assisted ophthalmic surgery has been the focus of intense interest in recent years. In this study, the authors tested the potential utility of a robotic armrest in ophthalmic surgery. The iArmS device consists of a forearm rest attached to a...
Lagophthalmos as a potential complication of COVID-19
Lagophthalmos is a condition associated with the inability to close the eyelids effectively, with the main cause being facial nerve palsy. The authors aimed to investigate whether lagophthalmos was associated with coronavirus infection (COVID-19) by comparing patients diagnosed with lagophthalmos...
Test combination which could detect prodromal Alzheimer disease
The authors prospectively recruited a convenience sample of individuals aged over 65 and either with a diagnosis of mild cognitive impairment (MCI) due to Alzheimer disease or normal cognition. Other types of dementia and severe neurological conditions were excluded. All...
Likelihood of developing multiple sclerosis after optic neuritis diagnosis
Optic neuritis (ON) is a relatively common cause of acute optic neuropathy in young patients which often presents as the first sign of multiple sclerosis (MS). There is a lack of evidence around the factors that are associated with the...
