H40.14 Capsular glaucoma with pseudoexfoliation of lens

Name of the Condition

• Capsular glaucoma with pseudoexfoliation of lens (ICD-10: H40.14)

Summary

Capsular glaucoma with pseudoexfoliation of lens is a type of secondary open-angle glaucoma associated with the accumulation of pseudoexfoliative material in the eye. This material deposits on the lens and other ocular structures, obstructing fluid drainage and leading to increased intraocular pressure, which can cause optic nerve damage and vision loss.

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., laser trabeculoplasty) to improve fluid drainage
• Surgery (e.g., trabeculectomy) in advanced cases to create an alternative drainage pathway

Prognosis and Follow-Up

Prognosis depends on early detection and management of intraocular pressure. Regular follow-up with an ophthalmologist is essential to monitor optic nerve health and adjust treatment as needed. Untreated or poorly controlled cases may lead to progressive vision loss.

Complications

• Permanent vision loss or blindness
• Optic nerve damage
• Secondary cataracts due to pseudoexfoliative material

Lifestyle & Prevention

• Regular eye examinations, especially for those over 60 or with risk factors
• UV protection (e.g., sunglasses)
• Avoiding long-term steroid use without medical supervision

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 presence of pseudoexfoliative material and confirm the diagnosis of capsular glaucoma. Ensure clinical notes specify the eye affected (if applicable) and any staging or severity details to support accurate coding.
