Table 2.
Type | Description |
---|---|
High AC/A ratio | Amount of deviation: Distance > near AC/A ratio is high |
Proximal convergence | Amount of deviation: Distance > near even after 30-60 min of occlusion AC/A ratio is normal |
Tenacious proximal fusion | Amount of deviation: Distance > near at first measurement After 60 min monocular occlusion near measurement increases |
Basic | Amount of deviation: Near=far |
Low AC/A ratio | Amount of deviation: Near > distance AC/A ratio is low |
Fusional CI | Amount of deviation: Near > distance Fusional convergence amplitude is poor |
Pseudo CI | Amount of deviation: Near > distance But distance measurement increases with 60 min of monocular occlusion |
AC/A: Accommodative convergence to accommodation ratio, CI: Convergence insufficiency
