Can OCT predict Alzheimer’s disease?

Simerdip Kaur takes a look at the latest ophthalmology-related news stories and asks which are based on facts and which are ‘fake news’. Headline: Can OCT predict Alzheimer’s disease? In 1986 Hinton et al. demonstrated evidence of optic nerve degeneration...

Inflammation and microvascular changes in diabetic retinopathy

Studies have shown that neurodegeneration and inflammation in the retina start early in diabetic retinopathy (DR) and can be present before the latter is clinically evident. The aim of this retrospective review of 99 diabetic patients was to evaluate retinal...

Moorfields Education: Implementing a non-medical intravitreal injection service (19 May)

This course is for clinicians working in an ophthalmic or medical retina setting, focusing on the treatment of age-related macular degeneration, retinal vein occlusion and diabetic oedema. .

Light reflex in preterm infants

In this study, the pupillary size and light reflex was examined in premature infants using infrared video-pupillography and stimuli of red and blue light. Only eyes of infants without retinopathy of prematurity were included in the study. Pupillary light reflexes...

Histopathological changes in rabbit retinitis pigmentosa

The authors report the histopathological changes of retinal ganglion cells (RGCs), optic disc and optic nerve in rabbit with advanced retinitis pigmentosa (RP). RP was recreated in rabbits by using bacterial artificial chromosome transgenesis, with the purpose of increasing understanding...

Retinal blood flow changes in glaucoma

This study examined the changes in retinal blood flow and vessel diameter after IOP reduction in high- and low-pressure glaucoma; exfoliation glaucoma (ExG) and normal-tension glaucoma (NTG). Glaucoma progression is seen at times in eyes despite IOP reduction and changes...

Optos announces new ultra-widefield colour image modality, providing additional retinal visualisation to eyecare professionals

Optos, Plc, the leading retinal imaging company, announces it is expanding the optomap® ultra-widefield (UWF™) retinal imaging modalities available with the California FA device to further assist eyecare professionals in disease management and treatment planning.

An update on inherited retinal disorders (part 2): Approaches to therapy for IRDs

Part 1 of this topic can be found here There are currently no proven cures for inherited retinal disease (IRD). However, multiple avenues of research are being investigated to better understand disease mechanisms and trial potential therapies that may slow...

Age-related macular degeneration

This review article offers an up to date review of the genetic and environmental risk factors associated with aetiology surrounding age-related macular degeneration (AMD). The article briefly describes the typical clinical presentation relating to early and late stages of the...

Somatostatin protects retinal pericytes

Diabetic retinopathy (DR) is a complication of diabetes, caused by high blood sugar levels damaging the retinal microvasculature. Mechanisms, such as oxidative stress and deposition of advanced glycation end products, leads to glial cell activation and neuronal apoptosis. Pericytes, contractile...

Changes in parafoveal retinal thickness after bariatric surgery in type 2 diabetics

Bariatric surgery induces an instant normalisation of blood glucose in as many as 80% of patients with type 2 diabetes. It has been previously reported that diabetic retinopathy (DR) is stable within one year after bariatric surgery. In this study,...

Retinal ganglion cell loss in diabetes and diabetic retinopathy

The aim of this observational case control study was to evaluate the association of diabetes and diabetic retinopathy (DR) with retinal ganglion cell loss. Cases were Chinese patients with type 2 diabetes with and without DR, aged 40-80 years. Eligible...
