Cent Afr J Med. 1998 Jun;44(6):152-4.

Abstract

Objective: To determine the reliability of village community development workers in screening for blindness in the community and to suggest an extraordinary role for these cadres.

Design: Diagnostic study.

Setting: Chivi District, Zimbabwe.

Subjects: A simple random sample of 148 out of 886 people selected from notification forms.

Main outcome measure: Sensitivity, specificity and predictive values.

Results: The screening method employed was found to have a sensitivity of 93% (95% CI), specificity of 32% (95% CI) and a predictive value for a positive result of 75%.

Conclusion: The use of village community development workers to screen for blindness in the community has proved to be a reliable alternative when there is shortage of both ophthalmic trained personnel and funds.
