Use of international interocular difference thresholds for optic neuritis diagnosis in clinical practice
Multiple sclerosis (MS) is the most common non-traumatic cause of disability in young people, and visual symptoms can be the initial manifestation in up to 20% of cases. Retinal examination can be helpful in making the correct diagnosis. The latest...Newer generation IOL platforms designed for high-quality visual performance after cataract surgery
Expanding intraocular lens (IOL) capabilities provide broadening options, ranging from next-generation monofocal IOLs for basic cataract surgery, to specialised premium IOLs for lens-based presbyopia correction and astigmatism correction at the time of cataract surgery. Rod McNeil considers several newer alternative...
Review of non-arteritic anterior ischaemic optic neuropathy
This article reviews the risk factors, clinical presentation and therapies that have been investigated for non-arteritic anterior ischaemic optic neuropathy (NAAION). Additionally, it provides an update from recent rodent and primate models, offering a new insight into the pathophysiology of...
Surgery technique for subluxation in Marfan syndrome
The authors evaluated the efficacy and safety of bimanual capsulorrhexis combined with sutureless scleral-fixated IOL implant in children with Marfan syndrome. Seven children (14 eyes) with subluxated lenses underwent bilateral surgery; four female, three male with mean age of 7.1...
Disc margin delineation using spectral domain OCT
Observing progressive anatomical changes of the optic nerve head is essential in the detection of progression in glaucoma. Imaging devices continue to evolve and are useful in detecting change in established glaucoma, although probably less useful in an initial diagnosis....The treachery of images – making sense of OCT imaging
In 1929 Belgian surrealist Rene Magritte produced his painting La Trahison des Images. It depicted an old fashioned pipe for smoking tobacco and underneath were the words “ceci n’est pas une pipe”, this is not a pipe. You may wonder...Use of off-the-shelf magnifying glasses as a cost-effective alternative for surgical loupes
Surgical loupes are an integral part of ophthalmic surgery on the ocular surface and in the periocular area. Available in different magnifications, they provide a clear view of the field of surgery which can greatly assist in identifying fine structures...
OCT-A imaging in Grave’s orbitopathy and orbital decompression
In this case series of 12 patients and 24 orbits, the authors describe the changes in the optic nerve and peripapillary blood vessel density in patients with moderate to severe Grave’s Orbitopathy (GO) undergoing orbital decompression. The patients undergoing orbital...
Long-term retinal changes following unilateral retrobulbar optic neuritis
The aim of this study was to assess the longitudinal changes in retinal nerve fibre layer (RNFL) thickness after a first attack of optic neuritis and to investigate the impact of treatment on RNFL thinning at one year after the...Optoversity 2024 happens on Sunday 7 April online
Students and companies have just a few days left to sign up for the annual Optoversity Challenge optometry competition and charity fundraiser for Vision Care for Homeless People (VCHP), run by student training provider Out of the Box Optics.
