Summary
Post-traumatic optic disc pallor in eyes with traumatic choroidal rupture may indicate poorer long-term vision. This finding highlights the importance of evaluating optic nerve health after eye injuries.
Area of Science:
- Ophthalmology
- Traumatic Optic Neuropathy
- Ocular Trauma
Background:
- The relationship between post-traumatic optic disc pallor and traumatic choroidal rupture is not well-defined.
- Understanding this association is crucial for managing ocular trauma patients.
Purpose of the Study:
- To investigate the association between indirect traumatic choroidal rupture and post-traumatic optic disc pallor.
- To compare ocular injury severity, fundus findings, and visual outcomes in patients with and without optic disc pallor.
Main Methods:
- Retrospective case comparison of nine patients with indirect traumatic choroidal rupture and optic disc pallor versus those without.
- Analysis of ocular injury characteristics, fundus examination findings, and visual acuity outcomes.
Main Results:
- Injury type and severity did not correlate with the risk of developing optic disc pallor.
- Optic disc pallor was linked to slightly worse long-term visual acuity (p=0.059).
- A relative afferent pupillary defect was strongly associated with optic disc pallor (p=0.016).
- Peripapillary retinal pigment epithelial abnormalities were common, suggesting localized trauma.
Conclusions:
- Post-traumatic optic disc pallor in the context of traumatic choroidal rupture may suggest a poorer visual prognosis.
- The presence of a relative afferent pupillary defect is a significant indicator of optic disc pallor in these cases.
- Peripapillary trauma is a likely cause of optic disc pallor following ocular injury.
