Summary
A new planned two-step vitrectomy safely and effectively removes large subretinal hematomas. This surgical strategy facilitates hemorrhage removal and retinal reattachment in patients with extensive subretinal bleeding.
Area of Science:
- Ophthalmology
- Surgical Innovation
Background:
- Large and thick subretinal hematomas pose significant surgical challenges.
- Current single-step vitrectomy techniques may be less effective for extensive hemorrhage.
Observation:
- A novel planned two-step vitrectomy was developed for subretinal hematomas involving 3+ quadrants.
- The first step involves initial vitrectomy and retinotomy, followed by a face-down position to mobilize hemorrhage.
- The second step removes mobilized hemorrhage and reattaches the retina.
Findings:
- The two-step approach successfully treated 4 patients with large subretinal hematomas.
- The face-down position effectively moved subretinal hemorrhage to the vitreous and anterior chamber.
- Subsequent hemorrhage removal and retinal reattachment were facilitated in the second surgical step.
Implications:
- Planned two-step vitrectomy offers a safer and more effective alternative for extensive subretinal hemorrhage.
- This technique may reduce overall surgical time compared to single-step procedures.
- It provides a viable option for complex retinal detachment cases involving significant hemorrhage.
