Open-globe ocular trauma causes visual deficiency; calculating the magnitude of the latter often misses the estimation in patients without follow-up.
to identify the modification of the postoperative proportion of visual deficiency in open-globe ocular trauma, which would introduce considering the proportion estimated in patients without follow-up.
Non-interventional, retrospective, longitudinal, analytical study. Visual outcome in eyes with open-globe trauma, with and without follow-up, was calculated using the Ocular Trauma Score. The observed postoperative proportion of visual deficiency was identified in eyes with follow-up; in eyes without follow-up, the postoperative proportion of visual deficiency was estimated using an analysis of scenarios: best (Ocular Trauma Score), mean (that of eyes with follow-up) and worst (last observation/no visual improvement). The estimated proportion of visual deficiency was added to that observed in eyes with follow-up, and the resulting proportion was compared with that expected in the sample, using the Ocular Trauma Score (χ(2)).
104 eyes, 70 without follow-up and 34 without it. In eyes with follow-up the expected proportion of visual deficiency was 58.6%, and the observed one was 71.4% (p = 0.1); the estimated proportion of visual deficiency in eyes without follow-up was 76.5%. The resulting postoperative proportion of visual deficiency in the sample would be 73.1%, which would overcome that expected by the Ocular Trauma Score (59.6%, p = 0.04).
In open-globe ocular trauma, the efficacy of surgery to reduce the proportion of visual deficiency would decrease with regard to the standard expected by the Ocular Trauma Score, if the deficiency estimated in eyes without follow-up were considered.
开放性眼球外伤会导致视力缺陷；计算后者的程度时，对于没有随访的患者，其估计往往会有偏差。
确定开放性眼球外伤术后视力缺陷比例的变化情况，这需要考虑对没有随访的患者所估计的比例。
非干预性、回顾性、纵向分析研究。使用眼外伤评分计算有和没有随访的开放性眼球外伤患者的视力预后。在有随访的眼中确定观察到的术后视力缺陷比例；在没有随访的眼中，通过情景分析估计术后视力缺陷比例：最佳情况（眼外伤评分）、平均情况（有随访的眼的情况）和最差情况（最后一次观察/视力无改善）。将估计的视力缺陷比例与有随访的眼中观察到的比例相加，并使用眼外伤评分（χ(2)）将所得比例与样本中预期的比例进行比较。
104只眼，70只没有随访，34只进行了随访。在有随访的眼中，预期的视力缺陷比例为58.6%，观察到的比例为71.4%（p = 0.1）；没有随访的眼中估计的视力缺陷比例为76.5%。样本中最终的术后视力缺陷比例将为73.1%，这将超过眼外伤评分预期的比例（59.6%，p = 0.04）。
在开放性眼球外伤中，如果考虑没有随访的眼中估计的视力缺陷，手术降低视力缺陷比例的疗效相对于眼外伤评分预期的标准会降低。
