ConditionBilateral advanced glaucoma secondary to phakic intraocular lens implantation with advanced glaucomatous optic neuropathy
Key Mechanisms
Target Population
Care Setting

Key Highlights

  • Patient presented with advanced glaucomatous optic neuropathy 25 years post pIOL implantation with IOP of 26 mmHg in RE and 24 mmHg in LE.

Guideline-Based Recommendations

Diagnosis

    Management

      Monitoring & Follow-up

      • Long-term follow-up is essential for patients with phakic intraocular lenses to detect complications, ideally every 6-12 months.

      Risks

        Patient & Prescribing Data

        Early diagnosis and intervention, such as MP-TSCPC or medications, are crucial to prevent advanced optic nerve damage.

        Clinical Best Practices

        • Utilize electrophysiological examinations to aid in the differential diagnosis of optic neuropathies.
        • Educate patients on the risks associated with long-term pIOLs.
        • Regular IOP monitoring is recommended for patients with pIOLs.
