H40.149 Capsular glaucoma with pseudoexfoliation of lens, unspecified eye

Name of the Condition

• Capsular glaucoma with pseudoexfoliation of lens, unspecified eye (ICD-10: H40.149)

Summary

Capsular glaucoma with pseudoexfoliation of lens, unspecified eye, is a type of secondary open-angle glaucoma. It involves the accumulation of pseudoexfoliative material on the lens and ocular structures, which obstructs fluid drainage and increases intraocular pressure. This can lead to optic nerve damage and vision loss if untreated.

Causes

This condition is primarily caused by the deposition of pseudoexfoliative material, a fibrous substance that accumulates in the eye. The material disrupts the normal drainage of aqueous humor, resulting in elevated intraocular pressure and subsequent optic nerve damage.

Risk Factors

• Age (more common in individuals over 60)
• Genetic predisposition
• Scandinavian or Mediterranean descent
• Exposure to ultraviolet (UV) rays

Symptoms

• Slowly progressing vision loss
• Elevated eye pressure
• Haloes around lights or eye discomfort (less common)

Diagnosis

Diagnosis involves a comprehensive eye examination by an ophthalmologist, including tonometry to measure intraocular pressure, gonioscopy to evaluate drainage angles, and imaging (e.g., optical coherence tomography) or visual field tests to assess optic nerve damage. The presence of pseudoexfoliative material on the lens is a key diagnostic indicator.

Treatment Options

Treatment focuses on lowering intraocular pressure to prevent optic nerve damage. Options include topical or oral medications, laser therapy, or surgical procedures to improve fluid drainage. The choice of treatment depends on the severity of the condition and individual patient factors.

Prognosis and Follow-Up

With early diagnosis and appropriate management, vision loss can often be slowed or prevented. Regular follow-up appointments are essential to monitor intraocular pressure, optic nerve health, and treatment effectiveness. Long-term management is typically required to maintain eye health.

Complications

Untreated or poorly controlled intraocular pressure can lead to permanent vision loss, optic nerve damage, or blindness. Other potential complications include cataracts and angle-closure glaucoma.

Lifestyle & Prevention

• Protect eyes from excessive UV exposure with sunglasses.
• Maintain regular eye examinations, especially for those with risk factors.
• Follow prescribed treatment plans consistently to manage intraocular pressure.

When to Seek Professional Help

Seek immediate medical attention if you experience sudden vision changes, severe eye pain, or haloes around lights, as these may indicate acute glaucoma or other serious eye conditions.

Tips for Medical Coders

When coding for capsular glaucoma with pseudoexfoliation of lens, unspecified eye (H40.149), ensure documentation supports the absence of a specified eye (right or left). Verify that pseudoexfoliative material and associated glaucoma are clearly documented to justify the diagnosis.
