White dot syndromes

It is fair to say that trainees and consultants who are not medical retina specialists are a bit scared of the so called retinal ‘white dot syndromes’. It is easy to understand why this is the case, as almost every...

FAZ measurement on OCTA

This paper aimed to test the AngioVue OCTAs reproducibility and interoperator concordance in evaluating the size of the foveal avascular zone (FAZ). The authors also investigated how the FAZs representation on the OCTA varied after metabolic activity. The right eye...

The effects of anti-VEGF therapy for NvAMD on retinal vasculature

This retrospective consecutive case series examined 54 eyes of 54 treatment-naïve neovascular age-related macular degeneration (N-AMD) patients. Thirty-three eyes received intravitreal aflibercept injections, and 21 eyes received intravitreal ranibizumab injections with unaffected fellow eyes (54 eyes) as controls. All image...

Screening for Sickle Cell Retinopathy (SCR): Why we do wide-field imaging, OCT/OCT-A for SCR – Newcastle upon Tyne Hospitals NHS Foundation Trust

I have been working in ophthalmology for over five years as a photographer and research co-ordinator, and it is fascinating, rewarding, and interesting to learn all about the different diseases associated with the eye. One condition that has been a...

Acute macular neuroretinopathy

Acute macular neuroretinopathy (AMN) is a rare condition that typically affects young women and presents with photopsia and paracentral scotomata [1]. We describe a case of severe acute macular neuroretinopathy, following Covid-19 infection. A 30-year-old woman presented to the urgent...

A unique case of macular burn from ‘toy’ laser

The first laser was created in 1960 and its name is an acronym for ‘light amplification by stimulated emission of radiation’. Laser technology has been used for medical, industrial, research and entertainment purposes in a variety of fields following extensive...

Macular thickness after strabismus surgery

The aim of this study was to determine whether strabismus surgery is associated with changes in macular thickness as detected by OCT. The study included 60 eyes of 30 patients with mean age of 28.9±14.2 years undergoing unilateral surgery. Mean...

Nystagmus and associated diagnosis

Patients with nystagmus attending a Low Vision clinic in Sweden were included in this study. Medical records were reviewed to exclude those with general diagnoses that could explain the nystagmus. The remaining group of patients underwent subjective refraction, retinoscopy, ocular...

Handheld OCT in children with Down’s syndrome

This article investigated the use of handheld optical coherence tomography (OCT) in children with Down’s syndrome. Fourteen children were recruited to the study with a mean age of 6 years and 10 months with 57% male. All patients were dilated....

Macular pigment in relatives of AMD patients

Blue light causes photo-oxidative retinal injury and macular pigment (MP), with lutein, zeaxanthin and mesozeaxanthin as the main components, as a filter that protects the macula from this damage. Previous studies indicated that low levels of macular pigment optical density...

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...

Beware the disc in myopic patients

Glaucoma is a chronic and progressive optic neuropathy characterised by damage of retinal ganglion cells. Evaluation of structural damage of the optic nerve is important in glaucoma diagnosis. The ISNT rule states that the neuroretinal rim width is generally widest...
