Purpose. To investigate the prognostic factors for visual outcome in traumatic cataract patients. Methods. The demographic features of traumatic cataract patients in Central China were studied. The factors that might influence the visual outcome were analyzed. The sensitivity and specificity of OTS (ocular trauma score) in predicting VA were calculated. Results. The study enrolled 480 cases. 65.5% of patients achieved VA at >20/60. The factors associated with the final VA were initial VA, injury type, wound location, the way of cataract removal, and IOL implantation. The sensitivities of OTS in predicting the VA at NLP (nonlight perception), LP/HM (light perception/hand motion), and ≥20/40 were 100%. The specificity of OTS to predict the final VA at 1/200-19/200 and 20/200-20/50 was 100%. Conclusion. The prognostic factors were initial VA, injury type, wound location, cataract removal procedure, and the way of IOL implantation. The OTS has good sensitivity and specificity in predicting visual outcome in traumatic cataract patients in long follow-up.
目的。探讨外伤性白内障患者视力预后的相关因素。方法。对中国中部地区外伤性白内障患者的人口统计学特征进行研究。分析可能影响视力预后的因素。计算眼部创伤评分（OTS）预测视力的敏感度和特异度。结果。本研究共纳入480例患者。65.5%的患者最终视力达到20/60以上。与最终视力相关的因素包括初始视力、损伤类型、伤口位置、白内障摘除方式及人工晶状体植入方式。OTS预测无光感（NLP）、光感/手动（LP/HM）及≥20/40视力的敏感度均为100%。OTS预测最终视力在1/200 - 19/200及20/200 - 20/50的特异度为100%。结论。预后相关因素为初始视力、损伤类型、伤口位置、白内障摘除手术及人工晶状体植入方式。在长期随访中，OTS对外伤性白内障患者视力预后具有良好的敏感度和特异度。
