Hypothesis

What are the prevalence and causes of blindness and low vision in Southern Sudan?

Conclusion

The studies reveal a high prevalence of blindness and low vision in Southern Sudan, particularly among the elderly and socioeconomically disadvantaged.

Supporting Evidence

  • Overall prevalence of blindness was estimated at 4.1%.
  • 7.7% of the population had low vision.
  • Cataract was the leading cause of blindness, accounting for around 40% of cases.
  • Trachoma was responsible for 35.3% of blindness, significantly higher than global averages.
  • 63.3% of children aged one to nine years showed signs of active trachoma.

Takeaway

In Southern Sudan, many people can't see well or are blind, especially older folks, and this is a big problem for their families and communities.

Methodology

Surveys were conducted in 22 randomly selected villages, examining 25 households from each village.

Potential Biases

Selection bias may have affected the results.

Limitations

The possibility of over-estimation due to selection bias was discussed.

Participant Demographics

Participants were from the Mankien district of Southern Sudan, with a focus on those over five years of age.
