Summary
Local anesthetic injections during chalazion removal can cause ocular perforation, leading to severe vision loss. Caution is advised during these procedures to prevent potential sight-threatening complications.
Area of Science:
- Ophthalmology
- Surgical Complications
Background:
- Chalazion removal is a common ophthalmic procedure.
- Complications, though rare, can significantly impact vision.
Observation:
- Two patients experienced sudden vision loss post-chalazion removal.
- Ophthalmologic examination revealed ocular perforation in both cases.
Findings:
- Case 1: Cherry red spot and perforation site noted.
- Case 2: Intraocular gas bubble and ischemic retina observed.
- These findings suggest iatrogenic ocular perforation due to anesthetic injection.
Implications:
- Anesthetic injections, even for minor procedures like chalazion removal, carry a risk of ocular perforation.
- High intraocular pressure from injections can compromise retinal and optic nerve blood supply.
- Extreme caution and avoidance of injection if perforation is suspected are crucial to prevent vision loss.
