Abstract

Introduiction: Convergence Insufficiency (CI) is the leading cause of eyestrain, blurred vision, double vision (diplopia), and/or headaches. In the evaluation of patients with ocular asthenopia, convergence insufficiency should be suspected. Convergence insufficiency disorder interferes with a person’s ability to see, read, learn, and work at near.In studies that used standardized definitions of Convergence insufficiency, investigators have reported a prevalence of 4.2% to 6% in school and clinic settings. Objectives: To assess the incidence & associated symptoms of convergence insufficiency among general population. Materials & Methods: Patients visiting the ophthalmology OPD of SSIMS & RC were included for the study. patients were given CISS( convergence insufficiency symptoms survey) questionnaire & convergence insufficiency was tested was tested with RAF rule. Result: In group A total 68 patients (13.6%) out of 500 were diagnosed with convergence insufficiency. Most common associated symptom was headache (32.35%) [p value<0.04]. In group B 50 patients(10%) out of 500 had convergence insufficiency. Most common associated symptom was headache (17.64%). Conclusion: Convergence insufficiency is more common in Group A (<18 yrs. of age) & is one of the important causes for headache (32.35%). So all the patients with headache should be tested for convergence insufficiency.
