Summary
Silver nitrate sticks can cause serious corneal injury and vision loss. This case highlights the risk of ocular complications from using silver nitrate for hemostasis after chalazion surgery.
Area of Science:
- Ophthalmology
- Ocular Toxicology
Background:
- Chalazion excision and drainage is a common ophthalmic surgical procedure.
- Hemostasis is often achieved using topical agents like silver nitrate sticks.
Observation:
- A 42-year-old woman developed corneal injury after silver nitrate application to the eyelid.
- The injury occurred during hemostasis following chalazion surgery.
Findings:
- Nine months post-procedure, greenish-yellow stromal deposits were observed.
- These deposits led to persistent decreased visual acuity.
Implications:
- Physicians must exercise caution when using silver nitrate applicator sticks near the eye.
- Awareness of potential silver nitrate-induced ocular toxicity is crucial for ophthalmologists and surgeons.
