Under pressure: intraocular pressure and bariatric surgery

Obesity in the general patient population is increasing. The National Institute for Health and Care Excellence recommends bariatric surgery with body-mass index (BMI) of over 40, or between 35-40 and other significant disease that could be improved with weight loss....

Macular pigment and dark adaptation in older population with normal maculas

Macular pigment (MP) such as lutein, zeaxanthin and meso-zeaxanthin are highly concentrated in the fovea. They protect the retina from damage of ambient blue light via antioxidant properties. In older eyes with normal healthy retina, macular pigment optical density (MPOD)...

Differences in elastometry of cornea and optic nerve head in both eyes of patients with NAION

Non-arteritic anterior ischaemic optic neuropathy (NAION) is an important cause of visual loss in the middle aged and elderly population. This prospective cross-sectional study investigates the biomechanical properties of optic nerve head (ONH) and cornea in both eyes of patients...

Paraneoplastic optic neuropathy features

This is a retrospective review of seven patients diagnosed with paraneoplastic optic neuropathy (PON) between January 2015 and June 2017. Five patients had a history of primary malignancy, including papillary thyroid carcinoma, type B thymoma, testicular seminoma and lung carcinoma....

Biometry measure after cycloplegia

The authors investigated optical biometry in an Indian paediatric population on normal and cataract paediatric eyes and studied the effect of cycloplegia on different parameters measured in these eyes. This was a prospective study of 76 eyes aged five to...

The global burden of age-related macular degeneration

Age-related macular degeneration (AMD) is the third leading cause of blindness (behind cataract and refractive error). The authors present the results of the Global Burden of Disease (GBD) 2015 study, which included 195 countries. The disability-adjusted life years (DALY) due...

Is myopia protective against progression of diabetic retinopathy?

This population-based cohort study assessed the association of refractive error with the incidence and progression of diabetic retinopathy (DR); 1562 eyes of 860 patients with diabetes and gradable retinal photographs were included. Baseline data was taken between 2004-2009 and follow-up...

Benefit of selenium and vitamin D supplementation in thyroid eye disease

There is some limited evidence of as association between thyroid eye disease (TED) and nutritional deficiencies including selenium and vitamin D. Prior studies show that selenium can reduce TPO-antibody concentrations and improve hypothyroidism and post-partum thyroiditis. Limited evidence also shows...

Choroidal vascularity in NAION

The authors present a cross-sectional, non-interventional study of healthy volunteers and those with non-arteritic anterior ischaemic optic neuropathy (NAION) recruited over a six-month period at a single site. NAION is the most common cause of acute optic neuropathy over the...

Childhood blindness and visual impairment in the Narayani Zone of Nepal

Up to 50% of childhood blindness is preventable or treatable, and its control is a high priority in the VISION 2020 initiative of the International Agency for the Prevention of Blindness. In this study, the authors utilised the rapid assessment...
