Endothelial cell loss using different graft injectors in DMEK

This study aimed to investigate endothelial cell loss between two injector systems in descemet membrane endothelial keratoplasty (DMEK) grafts; a glass injector – modified Jones tube and a plastic injector – closed system IOL injector, the Viscoject 2.2 system. DMEK...

The clinical spectrum of albinism

The authors sought to examine clinical correlates that may be related to foveal development in albinism with an aim to qualitatively describe the phenotype spectrum of albinism. Binocular best corrected visual acuity ranged from 20/20 to 20/80. Best corrected visual...

Investigating the effect of signal strength on mean retinal nerve fibre layer

Smartphone ophthalmoscopy vs. slit-lamp biomicroscopy in diabetic retinopathy

In this prospective, comparative, clinical study the authors’ aim was to assess the reliability and accuracy of smartphone ophthalmoscopy as compared with standard slit-lamp biomicroscopy in the grading of diabetic retinopathy. One hundred and twenty consecutive, new, diabetic patients underwent...

Sex differences in the relationship between obesity and choroidal nevus in US adults

The National Health and Nutrition Examination Survey (NHANES); a population-based survey conducted annually in the US by the Centers for Disease Control and Prevention, was used to identify populations at higher risk for choroidal naevus. Over a period of four...
