Summary
Radial-interrupted mattress sutures for scleral outfolding show greater macular translocation potential than scleral infolding. Further research is needed for age-related macular degeneration treatment.
Area of Science:
- Ophthalmology
- Surgical Techniques
- Retinal Diseases
Background:
- Macular translocation aims to reposition the macula to a healthier retinal area.
- Scleral infolding and outfolding are surgical techniques to achieve macular translocation.
- Age-related macular degeneration (AMD) with subfoveal choroidal neovascularization is a leading cause of vision loss.
Observation:
- Comparison of scleral infolding versus outfolding techniques in human cadaver eyes.
- Radial-interrupted mattress sutures for scleral outfolding were applied in a clinical case of AMD.
- Measurement of internal anteroposterior retinal contour changes after each technique.
Findings:
- Scleral infolding resulted in an average retinal contour decrease of 0.36 mm.
- Scleral outfolding created a significantly larger average decrease of 4.61 mm (P=.0001).
- Radial-interrupted mattress sutures for outfolding demonstrated greater potential for macular translocation.
Implications:
- Radial-interrupted mattress sutures may offer superior macular translocation compared to circumferential sutures.
- This technique holds promise for treating subfoveal choroidal neovascularization in AMD.
- Long-term efficacy and safety require further clinical investigation.
