ABSTRACT
Introduction
Anti-angiogenesis therapy with intravitreal anti-VEGF agents is now the standard-of-care treatment for myopic choroidal neovascularization (CNV).
Areas covered
We provide a critical review of the safety of all the anti-VEGF agents currently used for treating myopic CNV including ranibizumab, aflibercept, conbercept, bevacizumab, and ziv-aflibercept.
Expert opinion
Anti-VEGF therapy for myopic CNV with the currently available anti-VEGF drugs generally have favorable safety outcomes in the short-term. Nonetheless, ocular adverse events following anti-VEGF therapy for myopic CNV may develop and these include worsening or new development of myopic traction maculopathy, increased risk of retinal detachment, and progression of chorioretinal atrophy. Clinicians should be aware of these potential complications and evaluate them before and after anti-VEGF therapy.
Article highlights
Intravitreal injection of anti-VEGF agent is currently the standard of care treatment for patients with myopic CNV.
Phase 3 randomized clinical trials have evaluated the efficacy and safety of various intravitreal anti-VEGF agents including ranibizumab, aflibercept and conbercept for myopic CNV and results demonstrated excellent short-term visual acuity gain with favorable safety outcomes up to 1 year.
Patients with high myopia are more prone to develop various ocular complications especially peripheral retinal breaks, retinal detachment, myopic traction maculopathy and chorioretinal atrophy.
Development of chorioretinal atrophy is a main cause of long-term visual loss in patients with myopic CNV and the use of verteporfin photodynamic therapy in combination with anti-VEGF therapy should be avoided.
Anti-VEGF therapy in patients with myopic CNV may lead to progression or new onset of myopic traction maculopathy. Patients should be monitored regularly with optical coherence tomography after treatment to evaluate for potential myopic traction maculopathy and CNV recurrence.
