Severe Visual Impairment in Schools (A PEEK Study)

Abstract

Childhood visual impairment is a major public health concern. The global financial burden of childhood-onset blindness is greater than that of adult-onset blindness due to the longer span of living. The importance of good vision for education and socialisation from an early age has prompted the adoption of vision screening in schools by many national eye care programmes in Zimbabwe. Therefore, the aim and purpose of this study were to determine the prevalence of visual impairment and the pattern of eye conditions affecting school children screened during the course of the "Portable Eye Examination Kit (PEEK) project." The study was a retrospective review that utilized data that was collated and analysed from the PEEK project dashboard from June 2019 to December 2020 by well-trained eye health care providers. The sample size was 4591 school-going children aged between 5 to 20 years of age recruited from the Harare and Bulawayo schools. Results showed that 58% did not have any eye problems while 24% had a red watery and itchy eye, 10% had a red eye, 2% had lid and globe issues and 2% had strabismus. The visual acuity results showed that the majority of participants, 2/3, had a good vision as they recorded a Snellen acuity test score of 6/9 or better. In addition, 1/5 had mild visual impairment, and about 2% of the participants were legally blind. 15% of the participants recruited in this study had moderate to severe visual impairment.
