Stereoscopic photographs are a useful tool in the detection of glaucoma, however, the difficulty in obtaining them has seen them underused in favour of optical coherence tomography (OCT). A new device is attempting to redress this balance, enabling stereo-photography to be used alongside OCT for optimal practice.
As an objective measure of the function of retinal ganglion cells, pattern electroretinography (PERG) testing reveals subclinical optic nerve changes that may be critical for deciding when to start therapy to avoid vision loss from glaucoma progression.
A new list of 133 genetic variants can help predict whether someone might develop primary open-angle glaucoma (POAG).
Cataract remains the most common causes of blindness worldwide, followed by uncorrected refractive error, glaucoma, age-related macular degeneration (AMD), cornea-related diseases, trachoma and diabetic retinopathy, researchers believe.
The combined clinical use of pattern electroretinography for the detection of early glaucoma indicators and selective laser trabeculoplasty for intervention may help realise the potential of early detection and treatment.
Created for surgeons, by surgeons – a new method of approaching gel stent implantation provides better outcomes for patients.
Optical coherence tomography angiography (OCTA) is a new imaging technique that has the potential to move rapidly into routine clinical practice. OCTA comprises different OCT-based technologies, which enable the non-invasive assessment of retinal perfusion, based on red blood cell movement in the optic nerve head, the peripapillary and the macular retina.
Micropulse transscleral cyclophotocoagulation utilises a different delivery modality than its predecessor, continuous-wave laser cycloablation, to produce a biological reaction without the lethal effects caused by thermal buildup.
High-intensity focused ultrasound cyclocoagulation is safe and effective in most refractory glaucomatous eyes. Complete success was achieved in 80% (24/30) of treated eyes that had undergone the maximum of three procedures.
A pioneering dye-based technique that enables aqueous humour outflow to be studied has the potential to improve glaucoma angle-based procedures and surgery outcomes.
