H40.143 Capsular glaucoma with pseudoexfoliation of lens, bilateral

Name of the Condition

• Capsular glaucoma with pseudoexfoliation of lens, bilateral (ICD-10: H40.143)

Summary

Capsular glaucoma with pseudoexfoliation of lens, bilateral, is a type of secondary open-angle glaucoma affecting both eyes. 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 surgery to improve fluid drainage. Bilateral involvement may require treatment in both eyes.

Prognosis and Follow-Up

With early diagnosis and consistent treatment, vision loss can often be slowed or prevented. Regular follow-up appointments are essential to monitor intraocular pressure and optic nerve health. Untreated or poorly controlled cases may lead to progressive vision loss.

Complications

• Progressive vision loss or blindness
• Optic nerve damage
• Increased risk of cataracts

Lifestyle & Prevention

• Regular eye examinations, especially for those over 60 or with risk factors
• Protecting eyes from excessive UV exposure
• Managing other health conditions that may affect eye health

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 eye conditions.

Tips for Medical Coders

Document the bilateral nature of the condition clearly in the medical record, as this is required for accurate coding of H40.143. Ensure pseudoexfoliative material presence and glaucoma diagnosis are well-documented to support the code assignment.
