Summary
Unexplained retinal hemorrhage occurred in five patients after 23-gauge sutureless vitrectomy for macular holes. These hemorrhages resolved within months, suggesting potential causes related to surgical technique or patient positioning.
Area of Science:
- Ophthalmology
- Retinal Surgery
- Vitreoretinal Diseases
Background:
- 23-gauge sutureless vitrectomy is a minimally invasive surgical technique.
- It is commonly used for treating macular holes (MH) and macular hole retinal detachment (MHRD).
Observation:
- Five cases of unexplained retinal hemorrhage were observed post-surgery.
- Hemorrhages appeared within the first day after the vitrectomy procedure.
Findings:
- The retinal hemorrhages resolved spontaneously within several months.
- No significant residual damage was noted after the hemorrhages disappeared.
Implications:
- Potential causes include globe collapse during air perfusion through the cannula.
- Retinal vein congestion due to face-down positioning is another possible contributing factor.
- Further investigation is needed to elucidate the exact etiology of these hemorrhages.
