Abstract:
Age-related macular degeneration has a natural progression from the precursors (the drusen) towards atrophic or neovascular complications. Choroidal neovascularization is undoubtedly the aspect of the disease that benefits most from new therapeutical approaches. Destructive photocoagulation based on fluorescein angiography has demonstrated since 20 years its efficiency on choroidal neovascularization. The same approach based on indocyanine green (ICG) angiography would increase the number of patients available to therapy. Very recently photodynamic therapy has demonstrated its efficiency to stabilize visual acuity at least at two years in patients with choroidal new vessels predominantly well defined. Other treatment developments are considered, such as refinement of photocoagulation techniques or of surgery. Until now, none has demonstrated its efficiency although they raise justified hopes. The future approaches rely upon the progress of the research both in physiopathology of the disease and on the angiogenic process requiring a constant interaction with all thematics of research. Finally, palliative treatments will be required before heading up to a preventive treatment.
Insights
New therapies are improving age-related macular degeneration (AMD) treatment, particularly for choroidal neovascularization. Photodynamic therapy shows promise in stabilizing vision, with ongoing research exploring further advancements.
Area of Science:
- Ophthalmology
- Medical research
Background:
- Age-related macular degeneration (AMD) progresses from drusen to atrophic or neovascular complications.
- Choroidal neovascularization (CNV) is a key aspect of AMD benefiting from therapeutic advancements.
Purpose of the Study:
- To review current and emerging therapeutic approaches for choroidal neovascularization in AMD.
- To highlight the role of different imaging techniques and therapies in managing AMD.
Main Methods:
- Review of established treatments like fluorescein angiography-guided photocoagulation.
- Evaluation of newer modalities such as indocyanine green (ICG) angiography and photodynamic therapy (PDT).
- Consideration of surgical techniques and ongoing research in AMD pathophysiology and angiogenesis.
Main Results:
- Fluorescein angiography-guided photocoagulation has a 20-year track record of efficacy in treating CNV.
- ICG angiography may expand therapeutic options for CNV.
- Photodynamic therapy demonstrates efficacy in stabilizing visual acuity in patients with well-defined choroidal new vessels.
Conclusions:
- Photodynamic therapy offers a valuable option for managing CNV in AMD.
- Continued research into AMD pathophysiology and angiogenic processes is crucial for future treatment development.
- The progression towards palliative and eventually preventive treatments for AMD is anticipated.
