Managing Complications: Treatment Options and Strategies

It is important to remember that there is currently no treatment that “cures” the underlying stretching of the eyeball or reverses established macular atrophy in degenerative myopia ^[1]. Instead, modern medicine focuses on treating the specific complications that arise from that stretching. By managing these issues early and aggressively, you and your care team can work to preserve your functional vision for as long as possible.

Treating Leaks: Anti-VEGF Injections

The most common complication requiring active treatment is myopic choroidal neovascularization (mCNV)—the growth of abnormal, leaky blood vessels ^[2]. The gold standard for this is intravitreal anti-VEGF injections ^[1].

• How they work: These medications (such as ranibizumab, aflibercept, or bevacizumab—the latter often used off-label) block a signal in your eye that tells these “bad” blood vessels to grow and leak ^[1].
• The Schedule: Treatment is based on clinical and imaging evidence of activity rather than symptoms alone. Many patients start with just one injection and are then monitored closely. If new fluid appears on an OCT scan, another injection is given ^[3][4].
• Long-Term Goal: While these injections are effective at stopping leaks, the goal is stability. Recurrences are common, happening in about 25% to 33% of patients over the first 18 months, depending on the study population ^[5]. Long-term surveillance is required.
• Safety Warning: Intravitreal injections carry material risks, including infection, inflammation, pressure changes, or retinal tear. Seek urgent care if you experience severe pain, increasing redness, marked light sensitivity, or a substantial vision drop after an injection.

Surgical Options for Traction and Detachment

When the retina is physically pulled or lifted away from the back of the eye, mechanical solutions may be considered. However, surgery is not always immediately indicated for every issue ^[6].

• Observation: Many cases of stable or mild Myopic Traction Maculopathy (MTM) (such as asymptomatic foveoschisis) are safely observed without surgery.
• When Surgery is Considered: Surgery is evaluated based on symptomatic decline, progression, foveal detachment, a macular hole, or a retinal detachment.
• Surgical Options: In a vitrectomy (PPV), the surgeon removes the jelly-like vitreous inside your eye and peels away thin membranes pulling on the retina ^[7]. A scleral buckle or macular buckle alters the shape of the eye wall to support the retina ^[8][9]. These procedures address different anatomical problems, and your surgeon will select the approach based on your eye.

Post-Surgery Note: If a gas bubble is placed in your eye during surgery, you must absolutely avoid air travel and nitrous oxide anesthesia until your surgeon confirms it is safe. Note also that while surgery may successfully reattach the retina, it cannot restore vision lost to underlying macular atrophy.

The Nuance of Laser (Retinopexy)

You may have heard of “laser” for lattice degeneration (thinning in the side vision).

• When it’s used: Laser (or cryotherapy) is typically required promptly if you have a symptomatic retinal tear ^[10][11].
• When it’s watched: For many patients with asymptomatic lattice degeneration, “watching and waiting” is appropriate. Even if your fellow eye has had a detachment, prophylactic laser is not automatically required; the decision depends on the specific lesion, symptoms, subretinal fluid, and specialist examination ^[12][13][14].

Special Considerations for Cataract Surgery

Cataracts occur naturally with aging, but high myopia can be associated with an increased risk or earlier onset ^[15]. Cataract surgery requires specific planning:

• Calculation Challenges: Standard formulas used to pick your new lens (IOL) are less accurate in very long eyes. Your surgeon will choose an appropriate formula (like Barrett Universal II or EVO) based on your axial length and ocular history to aim for the best outcome ^[16][17].
• Retinal Risk: Surgery can slightly increase the risk of a future retinal detachment or macular swelling, depending on your age and retinal health ^[15][18].
• Realistic Expectations: Cataract surgery treats lens opacity, not macular atrophy or staphyloma. Your final vision will still depend on the underlying health of your retina ^[19].

Every treatment in degenerative myopia is a balance of risks and benefits. Your care team will tailor these options based on your specific META-PM category and the unique shape of your eye ^[20].
