Spasm of accommodation
A spasm of accommodation (also known as an accommodation, or accommodative, spasm) is a condition in which the
ciliary muscleof the eyeremains in a constant state of contraction. Normally, this contraction bends the lens to allow the eye to "accommodate" for near-vision. However in a state of perpetual contraction, the ciliary muscle cannot relax when viewing distant objects. This causes vision to blur when attempting to view objects from a distance. This may be caused be pseudomyopiaor latent hyperopia.
antimuscarinicdrops can be applied topically to relax the muscle, excessive pupil dilationmay occur as an unwanted side effect. The dilation may pose a problem since it could allow an increased amount of harmful ultraviolet lightto enter and damage the eye.
Patients who have accommodative spasm may benefit from being given a small plus prescription or through
Possible clinical findings include:
Amplitude of accommodationand Near point of convergence
