H40.141 Capsular glaucoma with pseudoexfoliation of lens, right eye

Name of the Condition

• Capsular glaucoma with pseudoexfoliation of lens, right eye (ICD-10: H40.141)

Summary

Capsular glaucoma with pseudoexfoliation of lens, right eye, is a type of secondary open-angle glaucoma. It involves the accumulation of pseudoexfoliative material on the lens and ocular structures of the right eye, 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

• Medications such as eye drops to lower eye pressure
• Laser therapy (Laser trabeculoplasty) to improve fluid drainage
• Surgery in advanced cases to provide an alternative drainage pathway

Prognosis and Follow-Up

With early diagnosis and consistent treatment, progression of vision loss can be slowed or halted. Regular follow-up appointments are essential to monitor intraocular pressure and optic nerve health. Long-term management is typically required to prevent complications.

Complications

• Progressive vision loss or blindness
• Optic nerve damage
• Increased risk of acute angle-closure glaucoma in some cases

Lifestyle & Prevention

• Regular eye examinations, especially for those with risk factors
• Protecting eyes from excessive UV exposure
• Maintaining overall eye health through routine care

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 pressure elevation or other serious conditions.

Tips for Medical Coders

Document the laterality (right eye) and the presence of pseudoexfoliation material to support accurate coding. Ensure clinical documentation specifies the eye affected and any associated findings to align with the code’s requirements.
