Although lots of studies have been reported on convergence insufficiency (CI), no specific case of CI among African patients has been reported. We report a case of symptomatic classic convergence insufficiency in a female student who previously had been misdiagnosed and managed for refractive error. This case highlights the need for comprehensive binocular vision assessment, administration of validated symptom questionnaires in cases of suspicious CI, and the use of simple and inexpensive vision therapy procedures to manage CI in optometric centres in developing countries.
