Overview
The most common non-strabismic binocular vision anomaly, in which the eyes struggle to sustain convergence for near work. Presents with near-work headache, eyestrain, reduced reading stamina, and intermittent near diplopia or words moving on the page. The signs are a receded near point of convergence, reduced positive fusional vergence at near, and a near phoria that sits more exophoric than the distance measure, with symptoms reproduced on sustained near fixation.
Recognition
Symptoms: what patients report
- Near work headache or frontal discomfort.
- Eyestrain and reduced reading stamina.
- Horizontal binocular diplopia that is worse at near, or intermittent near diplopia / words moving on the page.
- Reading avoidance or reduced concentration with sustained near tasks.
- Symptoms worse with prolonged reading, screens, or end-of-day near work.
- Symptoms may improve with rest or brief visual breaks.
Signs: what the examination shows
- Receded near point of convergence.
- Near exophoria greater than distance phoria.
- Reduced positive fusional vergence at near.
- Symptoms reproduced on sustained near fixation or vergence testing.
- Full ocular movements and no pupil abnormality in a typical presentation.
