To assess lens clarity after 3-port lens-sparing vitrectomy for stages 4A and 4B tractional retinal detachment secondary to retinopathy of prematurity.
In a retrospective, interventional, consecutive clinical case series, 108 eyes of 102 patients who underwent lens-sparing vitrectomy for stages 4A and 4B tractional retinal detachment from February 1, 1998, through January 31, 2004, were reviewed. All procedures and follow-up examinations were performed by a single surgeon. Lens clarity was assessed at the final follow-up examination.
Of the 108 eyes reviewed, 102 (94.4%) maintained clear lenses at the final follow-up examination, which ranged from 6 to 48 months (mean, 32 months) after the procedure. Thirty-two eyes had stage 4A detachments and 76 eyes had stage 4B.
Three-port lens-sparing vitrectomy may be performed with relatively low risk of cataract formation during the early postoperative period. Maintenance of a clear crystalline lens during the critical period of visual development may lead to better functional outcomes.
评估三通道保留晶状体玻璃体切除术治疗早产儿视网膜病变继发的4A期和4B期牵引性视网膜脱离后的晶状体清晰度。
在一项回顾性、介入性、连续性临床病例系列研究中，对1998年2月1日至2004年1月31日期间接受保留晶状体玻璃体切除术治疗4A期和4B期牵引性视网膜脱离的102例患者的108只眼进行了回顾。所有手术和随访检查均由一名外科医生完成。在最后一次随访检查时评估晶状体清晰度。
在接受回顾的108只眼中，102只（94.4%）在最后一次随访检查时晶状体保持清晰，该检查在手术后6至48个月（平均32个月）进行。32只眼为4A期脱离，76只眼为4B期。
三通道保留晶状体玻璃体切除术在术后早期形成白内障的风险相对较低。在视觉发育的关键时期保持晶状体透明可能会带来更好的功能预后。
