PURPOSE To evaluate the effect of orthoptic treatment on the AC/A (A, accommodation; C, convergence) and CA/C ratios in subjects with convergence insufficiency (CI). METHODS The change in AC/A and CA/C ratios after a 12-week period of home-based orthoptic treatment was examined in 10 subjects (mean age, 25.4+/-4.1 years [SD]). Both the AC/A and CA/C ratios were measured by using gradient resp...

BACKGROUND In paediatric ophthalmology retinoscopy may be performed immediately after an orthoptic examination or during an additional ambulatory visit. So far, no studies have been performed to investigate which of both procedures is preferred by the persons accompanying or examining the children. PATIENTS AND METHODS 32 consecutive children under the age of 16 were randomly assigned to have...

Patients with basic, convergence insufficiency (CI) and divergence excess (DE) types of intermittent ...

Background: The ocular motor system is complex and dependent on the cooperation of many different areas of the brain. Ocular motor functions may be disturbed by various factors resulting in strabismus, and abnormal fixational behaviour, which may interfere on a multitude of visual functions. To study binocular functions orthoptic methods may be used and when studying visual fixation eye-tracker...
