Degenerative myopia with choroidal neovascularization (CNV) is a serious condition that can lead to significant vision loss. The ICD-10 code H44.2A9 specifically refers to this condition when it is unspecified for which eye is affected. Here, we will explore the standard treatment approaches for this condition, focusing on the most effective and commonly used methods.

Understanding Degenerative Myopia and Choroidal Neovascularization

Degenerative myopia is a progressive eye disorder characterized by excessive elongation of the eyeball, leading to various complications, including CNV. CNV occurs when new, abnormal blood vessels grow beneath the retina, which can leak fluid and cause scarring, ultimately affecting vision. This condition is particularly concerning because it can lead to irreversible damage if not treated promptly.

Standard Treatment Approaches

1. Anti-VEGF Therapy

One of the primary treatments for CNV associated with degenerative myopia is the use of anti-vascular endothelial growth factor (anti-VEGF) injections. These medications work by inhibiting the action of VEGF, a protein that promotes the growth of abnormal blood vessels. Commonly used anti-VEGF agents include:

• Ranibizumab (Lucentis®): This is a widely used treatment that has shown efficacy in reducing fluid accumulation and improving visual acuity in patients with CNV[1].
• Aflibercept (Eylea®): Another effective option, aflibercept has a similar mechanism of action and is often used in cases where other treatments may not be effective[2].
• Brolucizumab (Beovu®): This newer agent has been introduced and may offer benefits in terms of dosing frequency and efficacy[3].

2. Photodynamic Therapy (PDT)

Photodynamic therapy is another treatment option for CNV. This involves the intravenous administration of a photosensitizing agent, such as verteporfin (Visudyne™), followed by exposure to a specific wavelength of light. The light activates the drug, which selectively targets and destroys the abnormal blood vessels while sparing surrounding healthy tissue. PDT can be particularly useful for certain types of CNV and may be used in conjunction with anti-VEGF therapy[4].

3. Laser Photocoagulation

In some cases, traditional laser photocoagulation may be employed. This technique uses a focused beam of light to seal off leaking blood vessels. However, it is less commonly used for CNV associated with degenerative myopia due to the risk of damaging surrounding retinal tissue and the potential for scarring[5].

4. Surgical Options

For patients with severe vision loss or complications from CNV, surgical interventions may be considered. These can include:

• Submacular Surgery: This involves removing the abnormal blood vessels and any associated scar tissue from beneath the retina.
• Retinal Translocation: In some cases, the retina may be repositioned to a healthier area of the eye, although this is less common and typically reserved for advanced cases[6].

5. Monitoring and Follow-Up

Regular monitoring is crucial for patients with degenerative myopia and CNV. This typically involves:

• Optical Coherence Tomography (OCT): This imaging technique allows for detailed visualization of the retina and can help assess the effectiveness of treatments.
• Fluorescein Angiography: This test helps to visualize blood flow in the retina and can identify areas of leakage or abnormal vessel growth[7].

Conclusion

The management of degenerative myopia with choroidal neovascularization involves a multifaceted approach, primarily focusing on anti-VEGF therapy and photodynamic therapy. Regular monitoring and follow-up are essential to assess treatment efficacy and make necessary adjustments. As research continues, new therapies and techniques may emerge, offering hope for improved outcomes in patients suffering from this challenging condition. If you or someone you know is affected by this condition, consulting with a retina specialist is crucial for personalized treatment planning.
