Summary
Indocyanine green (ICG) staining for cataract surgery can spread to the posterior segment. This rare complication led to retinal toxicity and required a vitrectomy to remove the dye.
Area of Science:
- Ophthalmology
- Surgical Innovation
- Medical Complications
Background:
- Phacoemulsification is a common cataract surgery technique.
- Indocyanine green (ICG) is used to stain the anterior capsule during certain cataract surgeries.
- Traumatic cataracts present unique surgical challenges.
Observation:
- ICG staining of the anterior capsule was performed for a traumatic cataract.
- During surgery, the ICG dye unexpectedly extended into the posterior segment of the eye.
- Postoperative examination revealed retinal toxicity attributed to the ICG dye.
Findings:
- The patient developed significant retinal toxicity following ICG staining.
- A vitrectomy procedure was necessary to remove the ICG from the posterior segment.
- The likely route of ICG extension was through a defect in the zonular fibers.
Implications:
- This case highlights a potential risk of ICG dye migration during cataract surgery.
- Zonular dehiscence may be a critical factor in posterior segment ICG extension.
- Careful patient selection and surgical technique are crucial when using ICG in complex cataract cases.
