ROP anti-VEGF treatment review

The purpose of this review was to consider data relating to risks and benefits of the use of anti-VEGF treatment for retinopathy of prematurity (ROP) over the past five years of 2015-2020. Ocular benefits include treatment of aggressive posterior ROP,...

Deciphering dark retinal patches

We present a case of bilateral extensive dark without pressure (DWP) located outside the retinal vascular arcades in a young female. This retinal finding is benign but, in some instances, darkened retinal patches could be associated with potential sight-threatening conditions....

Ocular bubbly: a vitreoretinal update on the art of gases

The authors remind us of the revolutionary impact gases have had on retinal surgery. In 1938, Rosengren attempted to improve his retina repair surgical outcomes [1]. He discovered that suturing the retina or pressing externally on the sclera were not...

Handbook of Retinal OCT

This is not a large colour atlas for optical coherence tomography (OCT) with comprehensive reference lists offering an in-depth description of this popular technology, but an up-to-date pocket or handbag-sized, soft-backed textbook that is likely to become a well-thumbed primer...

PD-1 and retinal ganglion cell death

Death of retinal ganglion cells (RGC) in conditions like glaucoma leads to permanent visual loss. RGC death can be due to the initial stress such as raised intraocular pressure or secondary to mechanism such as oxidative stress. Programmed cell death-1...

ILM peeling in primary rhegmatogenous retinal detachment

This author retrospectively analysed the correlation between internal limiting membrane (ILM) peeling and the occurrence of a postoperative epiretinal membrane (ERM) in patients who underwent vitrectomy for rhegmatogenous retinal detachment (RD). There were 135 medical records investigated. Seventy patients underwent...

Normal reference values for the RETeval device

The purpose of this study was to provide normative data of full-field electroretinography (ERG) responses in the paediatric population using the RETeval device in healthy children with normal retinas. This was a prospective study of 38 eyes of 20 patients...

Transfected RPE cells inhibit AMD in rats

Age-related macular degeneration (AMD) is a leading cause of blindness in the elderly. Wet AMD is characterised by choroidal neovascularisation, new vessels into the retina, leading to leakage and tissue damage. Many proangiogenic factors particularly vascular endothelial growth factor (VEGF)...

Hyper reflective foci (HRF) on OCT in diabetic retinopathy

This study investigated the presence of hyper reflective foci (HRF) in asymptomatic patients affected by type 1 or type 2 diabetes, separately, without clinically significant diabetic macular oedema and visual impairment. In total 71 eyes with non-proliferative diabetic retinopathy were...

Retinal prosthetics: science fiction or a vision for the future?

“Is it a fact – or have I dreamt it – that, by means of electricity, the world of matter has become a great nerve, vibrating thousands of miles in a breathless point of time?” – Nathaniel Hawthorne, The House...

The bionic eye – behind the headlines

Multiple visual prosthetic projects and other vision regeneration initiatives being tested in preclinical and clinical development worldwide illustrate continuing progress and opportunities in addressing profound blindness from hereditary retinal diseases and other causes (Table 1). Three implantable bionic vision systems...

Retinal arteriovenous malformation

A 24-year-old Caucasian girl reported to the eye clinic with the complaint of painless decreased vision in her right eye. She had no history of infectious disease, trauma, systemic malignancy or other systemic complaint. Her best corrected visual acuity was...
