H52.533 Spasm of accommodation, bilateral

Name of the Condition

• Spasm of accommodation, bilateral

Summary

Spasm of accommodation, bilateral is a condition characterized by an involuntary, sustained contraction of the ciliary muscles in both eyes, impairing their ability to relax and focus on distant objects. This results in blurred distance vision in both eyes while near vision remains relatively unaffected. The condition disrupts the normal balance between near and far focusing, leading to visual discomfort and functional impairment affecting both eyes.

Causes

Spasm of accommodation, bilateral may result from neurological dysfunction affecting the ciliary muscles, psychological stress, or prolonged near work without adequate rest. Underlying conditions such as head trauma, ocular inflammation, or systemic diseases impacting ocular innervation can also contribute to the development of this spasm in both eyes.

Risk Factors

• Prolonged near work (e.g., reading, screen use) involving both eyes
• Psychological stress or anxiety
• History of ocular trauma or inflammation affecting both eyes
• Neurological conditions affecting eye muscle control
• Use of medications with parasympathomimetic effects

Symptoms

• Blurred distance vision in both eyes
• Difficulty shifting focus from near to far objects with both eyes
• Eyestrain or headaches during distance viewing
• Sensation of "tight" or fatigued eyes
• Possible diplopia (double vision) in severe cases

Diagnosis

Diagnosis involves a comprehensive eye examination, including visual acuity tests, refraction assessments, and accommodation amplitude measurements. Additional evaluations may assess pupillary responses and ocular motility to rule out other conditions. A detailed patient history, including recent visual tasks and stress levels, is also considered.

Treatment Options

Treatment focuses on addressing underlying causes and relieving symptoms. Options may include discontinuing or adjusting medications, implementing stress management techniques, and prescribing corrective lenses for temporary distance vision support. In some cases, vision therapy or cycloplegic agents may be used to relax the ciliary muscles.

Prognosis and Follow-Up

Prognosis is generally favorable with appropriate management, as symptoms often resolve with rest or treatment of contributing factors. Follow-up care typically involves monitoring visual function and adjusting interventions as needed. Regular eye examinations are recommended to ensure resolution and prevent recurrence.

Complications

Untreated or prolonged spasm may lead to persistent blurred distance vision, chronic eyestrain, or reduced quality of life due to visual impairment. In rare cases, it could contribute to secondary issues like headaches or difficulty with daily activities requiring clear distance vision.

Lifestyle & Prevention

Preventive measures include taking regular breaks during prolonged near work, practicing good ergonomics, and managing stress. Adequate sleep and avoiding excessive screen time may help reduce the risk of developing or worsening the condition.

When to Seek Professional Help

Seek medical attention if blurred distance vision persists, worsens, or is accompanied by severe headaches, eye pain, or double vision. Prompt evaluation is important to rule out other serious ocular conditions and initiate appropriate treatment.

Tips for Medical Coders

Document the bilateral nature of the spasm and any contributing factors (e.g., stress, medication use) to support accurate coding. Ensure clinical notes specify the condition affects both eyes and include details on diagnostic findings or treatment approaches to justify the code selection.
