EYE - Glaucoma
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 eye may appear to be a comparatively simple organ and yet its optical system is complex and continues to be a source of investigation and research. The major optical elements are considered to be the cornea and the lens...

OCT, optic neuritis, optical coherence tomography, RNFL, steroid
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...
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...Conservative management of concomitant strabismus

EYE - General
The aim of management for all patients with strabismus should centre around four goals: to prevent amblyopia, to alleviate symptoms, to restore binocular single vision (BSV) and to improve ocular alignment. The conservative management options available for strabismus include observation,...
Cybersight: Using OCT as an Approach to Diagnose Glaucomatous and Other Optic Neuropathies
19 July 2024
Clinically, the difference between glaucomatous and simple optic atrophy of other origins is not always clear. OCT with the ability to image and measure inner retinal layers in the macula and peripapillary area, with the measurement of rim atrophy, is...
OSA Insights to Market win praise from members
OSA members praised the breadth of optical market insights provided by the Autumn meeting this week as a broad spectrum of suppliers gathered in London, reinforcing the strength of the trade body.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...

Detection rate, optic nerve disease, relative afferent pupillary defect, standard values
The authors have previously reported on use of the RAPDx device for evaluating relative afferent pupillary defects (RAPD). RAPDx objectively determines the magnitude of RAPD by presenting light stimuli alternately to pairs of eyes with laterality. The parameters of amplitude...
Optic nerve head perfusion response to reduced blood pressure and increased intraocular pressure

EYE - Glaucoma
The purpose of this prospective study was to test the hypothesis that blood flow autoregulation in the optic nerve head has less reserve to maintain normal blood flow where there is a blood pressure induced decrease in ocular perfusion pressure...
An interesting presentation of ruptured anterior communicating artery aneurysm with acute monocular vision loss

EYE - Neuro-ophthalmology
The authors report an interesting case of a 60-year-old man presenting with acute monocular vision loss accompanied by periorbital pain as an unusual presentation of subarachnoid haemorrhage (SAH) from ruptured anterior communicating artery aneurysm. The patient did not present with...
