To evaluate the anatomical and functional results of pars plana vitrectomy in eyes with osteo-keratoprosthesis, who have suffered retinal detachment.
An observational, retrospective study of 18 eyes which underwent pars plana vitrectomy for retinal detachment after an implantation of an osteo-keratoprosthesis, with a minimum of 1-year follow-up. A descriptive study and a Kaplan-Meier survival analysis for anatomical and functional success were performed. Anatomical success was defined as an attached retina at the end of vitreoretinal surgery with no redetachment during the follow-up. Functional success was defined as a postoperative visual acuity of more than or equal to 20/400.
The overall rate of anatomical success was 56%, and the anatomical survival rates were 67% and 53% at 6 months and 12 months, respectively, maintaining this last value at 24 months after pars plana vitrectomy. The overall rate of functional success was 17%, and the functional survival rates were 83%, 39%, and 14% at 6 months, 12 months, and 24 months after pars plana vitrectomy, respectively. The most frequent complication after retinal surgery was retroprosthetic membrane (33%).
Despite the reserved prognosis and the severe complications, vitrectomy represents a valid method for treating retinal detachment in patients with osteo-keratoprosthesis, with good anatomical results but poor visual acuity.
评估接受骨-角状突角膜移植术后发生视网膜脱离的患者行玻璃体切除术的解剖和功能结果。
这是一项回顾性观察研究，共纳入 18 只眼，这些眼在植入骨-角状突角膜移植术后发生视网膜脱离，且至少随访 1 年。对解剖和功能成功进行描述性研究和 Kaplan-Meier 生存分析。解剖成功定义为玻璃体视网膜手术后视网膜完全贴附，随访期间无再次脱离。功能成功定义为术后视力≥20/400。
总体解剖成功率为 56%，6 个月和 12 个月时的解剖生存率分别为 67%和 53%，在玻璃体切除术后 24 个月时保持最后一个数值。总体功能成功率为 17%，6 个月、12 个月和 24 个月时的功能生存率分别为 83%、39%和 14%。视网膜手术后最常见的并发症是后发性角膜膜（33%）。
尽管预后较差且并发症严重，但玻璃体切除术是治疗骨-角状突角膜移植术后视网膜脱离的有效方法，具有良好的解剖结果，但视力较差。
