Blindness from retrobulbar injection into the optic nerve.
Ophthalmic Surgery
|June 1, 1986
Summary
Sharp retrobulbar needles can cause severe visual loss by injecting into the optic nerve sheath. A modified technique is presented to reduce the risk of optic nerve trauma during retrobulbar injections.
Area of Science:
- Ophthalmology
- Neuro-ophthalmology
Background:
- Retrobulbar injections are common ophthalmic procedures.
- Atkinson's technique for retrobulbar injection has been associated with complications.
Observation:
- Two patients experienced severe visual loss after retrobulbar injections.
- Clinical findings included optic disc edema, retinal edema, and hemorrhages.
Findings:
- Injection into the optic nerve sheath is a cause of visual impairment.
- The use of sharp retrobulbar needles is implicated in optic nerve trauma.
Implications:
- A modified retrobulbar injection technique is proposed.
- This modified technique aims to minimize the risk of optic nerve damage.
