Study reveals increase in Charles Bonnet Syndrome symptoms due to COVID-19
A study published today in BMJ Open Ophthalmology has shown the impact of COVID-19 on those already experiencing vivid hallucinations as a result of Charles Bonnet syndrome (CBS).
Treatment of Type 1 ROP with intravitreal bevacizumab or laser photocoagulation according to retinal zone
This is a retrospective review of charts of 54 consecutive very low birth weight (VLBW) infants between June 2011 and January 2015 from Berlin, Germany. Type 1 ROP (posterior ROP, n=33; peripheral zone 2, n= 21) were treated with either...
Screening for ROP using wide-angle digital retinal photography by non-ophthalmologists
This is a systematic review article to evaluate the accuracy of digital retinal photography (DRP) performed by trained personnel (non-ophthalmologists) in diagnosing clinically significant retinopathy of prematurity (ROP). The authors used search engines including Medline, EMBASE, CINAHL and Cochrane databases....
Structural effects of migraine on the retina
Migraine is a common, chronic, multifactorial neuro-vascular disorder typically characterised by recurrent attacks of disabling headache and autonomic nervous system dysfunction (migraine without aura). Up to one third of patients also have neurological aura symptoms (migraine with aura). The objective...
B-scan ultrasonography
B-scan ultrasonography is commonly employed for the diagnosis and follow-up of ocular trauma. This retrospective study looked at the accuracy and predictive ability of B-scan ultrasonography following open globe repair. Of the 965 patients identified with open globe injuries at...
The effect of everolimus on retinal pigment epithelium and proliferative vitreo-retinopathy
The principal cells involved in proliferative vitreo-retinopathy (PVR) are retinal pigment epithelial cells (RPE). Everolimus is a drug used in renal cell carcinoma which targets and inhibits a key regulatory protein in cancer (mTOR). In this study, the authors investigated...
Gender variations in retinopathy
The Tromso Eye Study is a substudy of the Tromso Study; a population based longitudinal study based in Norway. The extensive 5869 participants had no diabetes and were aged between 30-87 years. Retinal images from both eyes were taken using...
Effects of blood donation on the physiology of the eye
Hypovolaemia is a state of decreased blood volume, the reduction of which reduces tissue perfusion which may in turn lead to cellular hypoxia and end-organ damage. In blood donation, 500ml of blood is collected in ten minutes. This equates to...
Ocular manifestation of Marfan Syndrome
This repeated cross-sectional study collected data in 2003-2004 and 2014-2015 to investigate changes in ocular features in Marfan syndrome (MFS) fulfilling the Ghent-2 criteria. Ghent-2 is a set of criteria by which MFS are identified and includes aortic root aneurysm...
Microperimetry measurements in anisometropic amblyopia
The authors aimed to evaluate retinal sensitivity and fixation characteristics in children with anisometropic amblyopia by macular analyser integrity assessment (MAIA) microperimetry and to compare the results between amblyopia and fellow eyes. The study included 39 children; 21 female –...
Changes in drusen and retinal layer volumes prior to CNV development
This retrospective longitudinal study looked at patients with wet age-related macular degeneration (AMD) in one eye who subsequently developed wet AMD in the fellow eye. The aim was to discover whether drusen characteristics or volumes of retinal layers correlate with...
