H40.142 Capsular glaucoma with pseudoexfoliation of lens, left eye

Name of the Condition

• Capsular glaucoma with pseudoexfoliation of lens, left eye (ICD-10: H40.142)

Summary

Capsular glaucoma with pseudoexfoliation of lens, left eye, is a type of secondary open-angle glaucoma. It involves the accumulation of pseudoexfoliative material on the lens and ocular structures of the left 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 (e.g., eye drops to lower intraocular pressure)
• Laser therapy (e.g., trabeculoplasty)
• Surgical interventions (e.g., trabeculectomy or drainage implants)

Prognosis and Follow-Up

Prognosis depends on early detection and management. Regular follow-up with an ophthalmologist is essential to monitor intraocular pressure and optic nerve health. Timely treatment can slow or prevent vision loss, but progression may occur if the condition is not controlled.

Complications

• Progressive vision loss
• Optic nerve damage
• Blindness (if untreated)

Lifestyle & Prevention

• Regular eye examinations, especially for those 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 laterality (left eye) and confirm the presence of pseudoexfoliative material on the lens. Ensure the diagnosis aligns with clinical findings and that the code H40.142 is used for the left eye specifically. Verify that no other eye conditions are present that would require a different code.
