The effectiveness of wide-angle fusional stimulation was evaluated in 13 patients with convergence insufficiency. These patients were referred to us because they either did no respond to or could not tolerate conventional treatment. Wide-angle fusional stimulation resulted in significant enlargement of fusional amplitudes and the alleviation of symptoms for 11 of the patients. Long-term follow-up indicates that these patients remain asymptomatic and that their increased fusional amplitudes persist.
