Hypoaccommodative convergence insufficiency: symptoms, diagnosis ad therapy

ABSTRACT

Hypoaccommodative convergence insufficiency is a relatively uncommon binocular vision abnormality characterized by low amplitude of accommodation and convergence, reduced AC/A ratio, blurred near vision, fatigue around the eyes, intermittent diplopia for near fixation, and frontal headaches. Hypoaccommodative convergence insufficiency is not amenable to orthoptic therapy and, consequently, an early differential diagnosis is clinically important. This report a case of hypoaccommodative convergence insufficiency associated with a peculiar symptom is presented. The physiological bases of the symptoms and the therapy are described
