Strabismus And Amblyopia In Africa – A Systematic Review And Meta-Analysis, Prince Kwaku Akowuah, Samuel Adade, Andrews Nartey, Ebenezer Owusu, Richard Donkor, Stephen Ankamah-Lomotey

Articles

The objective of this review was to estimate the prevalence of strabismus and amblyopia in Africa. A systematic online literature search was conducted for articles on strabismus and amblyopia in Africa. Meta-analysis was performed, using the Freeman-Tukey double arcsine transformation, to estimate the prevalence of strabismus and amblyopia in Africa. Subgroup analyses were conducted according to age, gender, study year, and type of amblyopia. Meta-regression was used to evaluate the influence of predetermined factors on the prevalence of amblyopia. 8 (1 population-based & 7 school-based) and 21 (3 population-based & 18 school-based) studies on strabismus and amblyopia with sample sizes …

Regional Variations And Temporal Trends Of Childhood Myopia Prevalence In Africa: A Systematic Review And Meta-Analysis, Emmnuel Kobia Acquah, Daniel Ian Flitcroft, Prince Kwaku Akowuah, Gareth Lingham, James Loughman

Articles

Purpose: To provide contemporary and future estimates of childhood myopia prevalence in Africa.

Methods: A systematic online literature search was conducted for articles on childhood (≤18 years) myopia (spherical equivalent [SE] ≤ −0.50D; high myopia: SE ≤ −6.00D) in Africa. Population-or school-based cross-sectional studies published from 1 Jan 2000 to 30 May 2021 were included. Meta-analysis using Freeman–Tukey double arcsine transformation was performed to estimate the prevalence of childhood myopia and high myopia. Myopia prevalence from subgroup analyses for age groups and settings were used as baseline for generating a prediction model using linear regression.

Results: Forty-two studies from 19 …

Impact Of Computer Experience On The Viability And Repeatablity Of The Moorfields Motion Displacement Test In A Developing And Underserved African Setting, James Loughman, Carmen Gonzalez Alvarez, Gay Mary Verdon-Roe, Roger Anderson, Ramos Antonio Manuel, Kovin Naidoo

Articles

Background: The current study was designed to explore the effect of computer experience on the viability and testretest repeatability of the Moorfields Motion Displacement Test (MMDT), a novel computer-driven glaucoma screening device, in an African community setting. Methods: 164 healthy subjects were recruited from a semi-rural Mozambican environment, and stratified according to computer experience (computer naïve: n=85, computer familiar: n=79). A suprathreshold screening test algorithm was employed, and the global probability of true damage (GPTD), testing time (TT) and false positive (FP) response rate were recorded. The visual field test was conducted twice on the same eye, and results compared …
