Medical condition
Accommodative insufficiency
Differential diagnosis
Convergence insufficiency.
Accommodative insufficiency (AI) involves the inability of the eye to focus properly on an object. Accommodation is the adjustment of the curvature of the lens to focus on objects near and far.
In this condition, amplitude of accommodation of a person is lesser compared to physiological limits for his age.[1] AI is generally considered separate from presbyopia, but mechanically both conditions represent a difficulty engaging the near vision system (accommodation) to see near objects clearly. Presbyopia is physiological insufficiency of accommodation due to age related changes in lens (decreased elasticity and increased hardness) and ciliary muscle power.[1]
AI is commonly present in people with convergence insufficiency.[2]
