H52.523 Paresis of accommodation, bilateral

Name of the Condition

• Paresis of Accommodation, Bilateral

Summary

Paresis of accommodation, bilateral, is a condition where both eyes have reduced ability to adjust focus from distant to near objects. This occurs due to weakness or dysfunction in the ciliary muscles, which control lens shape for proper focusing. The condition may result in blurred vision during close tasks and difficulty shifting focus between distances in both eyes.

Causes

Accommodation paresis can stem from various factors, including neurological disorders affecting the ciliary nerves, systemic diseases impacting ocular muscle function, or medications with anticholinergic properties. Trauma to the eye or head, as well as age-related changes, may also contribute to the condition.

Risk Factors

• Advanced age, particularly presbyopia
• History of eye trauma or surgery
• Neurological conditions (e.g., multiple sclerosis)
• Use of medications that affect parasympathetic function
• Systemic diseases like diabetes or myasthenia gravis

Symptoms

• Difficulty focusing on near objects with both eyes
• Blurred vision when shifting from distant to near tasks in both eyes
• Eyestrain or headaches during close work involving both eyes
• Squinting or frequent blinking to compensate with both eyes

Diagnosis

Diagnosis involves a comprehensive eye examination, including visual acuity tests, refraction assessments, and accommodation amplitude measurements. Additional evaluations may include neurological assessments to identify underlying causes.

Treatment Options

Treatment focuses on addressing the underlying cause, if identifiable. Options may include discontinuing or adjusting medications, managing systemic conditions, or using corrective lenses (e.g., reading glasses) to improve near vision. In some cases, vision therapy or specific medications may be considered.

Prognosis and Follow-Up

Prognosis depends on the underlying cause and its reversibility. Regular follow-up with an eye care professional is recommended to monitor vision changes and adjust treatment as needed. Early intervention may improve outcomes, especially if the cause is treatable.

Complications

Untreated or poorly managed paresis of accommodation may lead to persistent blurred near vision, reduced quality of life, and difficulty with daily tasks requiring close focus. In some cases, it may contribute to secondary issues like eyestrain or headaches.

Lifestyle & Prevention

• Use proper lighting for close work to reduce strain.
• Take regular breaks during prolonged near tasks (e.g., the 20-20-20 rule).
• Maintain overall health to support ocular function (e.g., managing diabetes).
• Avoid medications with anticholinergic effects when possible, if advised by a healthcare provider.

When to Seek Professional Help

Seek care if you experience persistent blurred near vision, difficulty focusing, or worsening symptoms. Prompt evaluation is important if symptoms interfere with daily activities or if there are signs of underlying neurological or systemic issues.

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record. Ensure the diagnosis is supported by clinical findings, such as accommodation testing results or a detailed history. For coding, verify that the documentation aligns with the specific criteria for H52.523 to ensure accurate assignment.
