Grading of cataracts using an objective scatter index
Vilaseca et al evaluated intraocular scattering in eyes with nuclear, cortical and posterior subcapsular cataracts (188 eyes, 136 patients) by means of an objective scatter index (OSI) obtained from double-pass images. They found a decrease in the BSCVA and an increase in the OSI with increasing cataract grade. There was good agreement between the OSI and lens opacities classification system III. OSI is a useful parameter for objective assessment of intraocular light scattering. (see page 1204)
Angle closure glaucoma in Europeans
Day et al estimated the prevalence of primary angle closure glaucoma (PACG) in European derived populations by means of systematic review and modelling of PACG prevalence data from population studies. Prevalence estimates were applied to the 2010 United Nations population. The prevalence of PACG in those 40 years or more was 0.4%. Three-quarters of the cases were females. It is estimated that there are 1.60 million cases of PACG in Europe (130 000 in the UK). …
