Summary
Indocyanine green (ICG) autofluorescence persisted for months after macular hole surgery. This sustained signal may increase the risk of retinal damage, warranting further investigation.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Retinal Surgery
Background:
- Macular hole surgery often involves internal limiting membrane (ILM) peeling.
- Indocyanine green (ICG) is used to enhance ILM visualization during surgery.
- The long-term effects of residual ICG in the macula are not fully understood.
Observation:
- Persistent indocyanine green (ICG) autofluorescence was observed in the central macula of patients.
- This autofluorescence was detectable up to 8 months following ICG-assisted ILM peeling.
- Utilized scanning laser ophthalmoscopy at 795 nm for imaging.
Findings:
- All four patients in the study exhibited persistent ICG autofluorescence.
- The fluorescence remained visible in the macula for an extended period post-surgery.
- This indicates a prolonged presence of ICG in the surgical area.
Implications:
- Persistent ICG autofluorescence may pose a risk for delayed photochemical damage to the retinal pigment epithelium (RPE).
- Further research is needed to quantify the potential for RPE injury associated with ICG-assisted ILM peeling.
- This highlights the importance of understanding the long-term safety profile of intraocular dyes in ophthalmic surgery.
