Cycloplegia
Cycloplegia
Cycloplegia (pronounced: sy-klo-plee-ja) is a medical condition that involves the paralysis of the ciliary muscle of the eye, resulting in a loss of accommodation or focus.
Etymology
The term "Cycloplegia" is derived from the Greek words "kyklos" meaning circle and "plege" meaning stroke. It refers to the circular muscle (ciliary muscle) of the eye that is affected in this condition.
Causes
Cycloplegia is most commonly caused by the use of cycloplegic drugs, such as atropine, cyclopentolate, and tropicamide. These drugs are used to temporarily paralyze the ciliary muscle in order to carry out certain diagnostic procedures or treatments on the eye. Other causes can include damage to the oculomotor nerve or certain systemic diseases.
Symptoms
The main symptom of cycloplegia is the inability to focus on near objects, a condition known as presbyopia. Other symptoms can include blurred vision, light sensitivity, and difficulty in reading.
Treatment
Treatment for cycloplegia is usually aimed at addressing the underlying cause. If the condition is caused by the use of cycloplegic drugs, it will typically resolve once the effects of the drugs wear off. In cases where cycloplegia is caused by damage to the oculomotor nerve or a systemic disease, treatment may involve managing the underlying condition.
