OCTA in geographic atrophy

4 August 2021 | | Retina / Uvea / Vitreous | Age-related macular degeneration, Angiography, Choriocapillaris, Choroid, Optical coherence tomography
In this article the authors aim to give an overview of the current literature concerning the application of OCT-A in geographic atrophy (GA). GA is a disease characterised by loss of outer retinal layers including photoreceptors, degeneration of the retinal...

Aflibercept treatment in polypoidal choroidal vasculopathy

1 April 2019 | | Retina / Uvea / Vitreous | Aflibercept, Caucasian population, Indocyanine green angiography, Optical coherent tomography, Polypoidal choroidal vasculopathy, Prospective study
The authors present a study to evaluate the anatomical and functional efficacy of aflibercept intravitreal (IVT) as a monotherapy in polypoidal choroidal vasculopathy (PCV) in a Caucasian population treated with initial three-monthly aflibercept IVT, followed by a bimonthly regimen for...

Subthreshold micropulse laser treatment in chronic central serous chorioretinopathy

1 February 2016 | | Retina / Uvea / Vitreous
This retrospective study was conducted to assess the treatment of 38 patients of chronic central serous chorioretinopathy with a 577-nm subthreshold micropulse laser (SML) Supra Scan Quantel Medical. Eighteen patients of these had persistent subretinal fluid (SRF) after photodynamic therapy....

What about the children? Cornea cross-linking for children with keratoconus

1 October 2017 | | Cornea / External Eye Disease | cornea, cross-linking, keratoconus, paediatric
Keratoconus can behave more aggressively in paediatric than in adult patients. Collagen cross-linking has been shown to slow the progression of keratoconus in adults. This systematic review determined the effectiveness of corneal collagen cross-linking (CXL) in children. For this study,...

Clinical relevance of the anatomic classification of neovascular age-related macular degeneration

1 February 2018 | | Imaging, Retina / Uvea / Vitreous, Ophthalmology
The author explains why an OCT-based classification of neovascular AMD is needed and how these neovascular subtypes may help to predict patients’ long-term visual outcome. Age-related macular degeneration (AMD) is a chronic and progressive neurodegenerative process involving the macula in...

It was the best of times, it was the worst of times... It was the season of Light, it was the season of Darkness... I am fortunate to work on a vitreoretinal firm at the moment and only a few...

Bionic eyes: deciphering the neural circuitry of vision restoration

3 June 2024 | | Ophthalmology
As the boundaries between technology and biology blur, retinal prosthetics, often dubbed ‘bionic eyes’, present a ground-breaking paradigm shift in addressing blindness. This article delves into the captivating scientific intricacies of these neural interfaces, exploring their mechanisms of action, current...

Principles of contact lens fitting in keratoconus

1 December 2015 | | Cataract and Refractive
Keratoconus is an ectatic condition of the cornea characterised by progressive conical distortion with irregular astigmatism, myopia and apical protrusion. Most cases progress slowly resulting in varying degrees of myopic astigmatism. Management of keratoconus includes spectacles, soft contact lenses, a...

Adaptive optics imaging: resolving single cells in the living eye

1 June 2014 | | Cornea / External Eye Disease
The human retina is unique in the central nervous system (CNS) in that it can be directly visualised non-invasively. Technological advances of several imaging modalities, including optical coherence tomography (OCT), multichannel scanning laser ophthalmoscopy (SLO) and fundus photography, have afforded...
