The association between post-traumatic optic disc pallor and traumatic choroidal rupture is poorly understood. To further define this relationship, nine cases of indirect traumatic choroidal rupture and post-traumatic optic disc pallor were compared with cases of indirect choroidal rupture without disc pallor in terms of severity of ocular injury, fundus findings, and visual outcome. The type and severity of the injury did not appear to influence the risk of optic disc pallor. Optic disc pallor was associated with a slightly poorer long term visual acuity than eyes without pallor (p = 0.059). The presence of a relative afferent pupillary defect was strongly associated with optic disc pallor (p = 0.016). Peripapillary retinal pigment epithelial abnormalities were a common finding, suggesting peripapillary trauma as a cause for optic disc pallor.
创伤后视盘苍白与创伤性脉络膜破裂之间的关联尚不清楚。为进一步明确这种关系，将9例间接性创伤性脉络膜破裂合并创伤后视盘苍白的病例与无视盘苍白的间接性脉络膜破裂病例在眼外伤严重程度、眼底表现及视力预后方面进行了比较。损伤的类型和严重程度似乎并未影响视盘苍白的风险。与无视盘苍白的眼睛相比，视盘苍白与稍差的长期视力相关（p = 0.059）。相对性传入性瞳孔障碍的存在与视盘苍白密切相关（p = 0.016）。视盘周围视网膜色素上皮异常是常见表现，提示视盘周围创伤是视盘苍白的一个原因。
