Usually, no laboratory studies are indicated.
Tensilon testing, acetylcholine receptor antibody titers, and single fiber electromyography (EMG) testing can be performed to differentiate convergence insufficiency from ocular myasthenia.
Cover testing and accommodation testing are the basic tests used to help diagnose this condition.
Measurement of fusional convergence amplitudes at near is also helpful.
