Cycloplegia is a medical condition characterized by the paralysis of the ciliary muscle of the eye, resulting in a loss of accommodation or focus. This condition is typically induced temporarily by the use of cycloplegic drugs, primarily for diagnostic purposes in ophthalmology.

Causes

Cycloplegia is most commonly caused by the administration of certain medications, known as cycloplegic drugs, which include atropine, cyclopentolate, and tropicamide. These drugs are used to paralyze the ciliary muscle, allowing for a more accurate measurement of refractive error in children and for the treatment of certain inflammatory conditions of the eye, such as iritis and uveitis.

Symptoms

The primary symptom of cycloplegia is the inability to focus on near objects, a condition known as presbyopia. Other symptoms may include light sensitivity, due to the inability of the pupil to constrict, and blurred vision.

Diagnosis

Diagnosis of cycloplegia is typically made through a comprehensive eye examination, which may include a refraction test to measure the eye's need for corrective lenses, a dilated eye exam to examine the retina and optic nerve, and a tonometry test to measure the pressure inside the eye.

Treatment

Treatment for cycloplegia is typically not necessary, as the condition is usually temporary and resolves once the effects of the cycloplegic drugs wear off. In cases where cycloplegia is caused by an underlying condition, such as iritis or uveitis, treatment of the underlying condition is necessary.
