Abstract

To determine the impact of uncorrected presbyopia on vision-related quality of life (QoL) and visual function (VF) among adults 40 years and older in Bungudu local government area (LGA) of Zamfara State, Nigeria. A population-based cross-sectional study in Bungudu LGA of Zamfara State Nigeria was conducted in 2012. Six-hundred and fifty persons at least 40 years of age were examined using a two-stage cluster random sampling-based on probability proportional to size. Presbyopia was defined as the inability to read N8 at 40 cm in an indoor illumination using LogMAR E-chart. Demographic information comprising of age, sex, occupation, and educational level among others was obtained from a pilot tested VF-14 and modified vision-related QoL questionnaire by trained interviewer. Out Of the 650 subjects enumerated 635 were examined given a response rate of 97.7%. The mean age of participants was 53.59 years (95% confidence interval:52.75%-54.43%). The crude prevalence of presbyopia was 30.4%, (95% CI: 26.8%-34.1%). The mean VF score of persons with presbyopia was 85.09, (95% CI: 83.09%-87.09%) and being female was strongly associated with high VF scores (P = 0.003). The VFs most impaired were the ability to read, write, use mobile phon...Continue Reading

Arrhythmias are abnormalities in heart rhythms, which can be either too fast or too slow. They can result from abnormalities of the initiation of an impulse or impulse conduction or a combination of both. Here is the latest research on arrhythmias.
