摘要
目的:利用光学生物测量技术,探讨玻璃体切除术后不同类型玻璃体视网膜病变的术后前房深度(ACD)的差异。方法:对14例患者的14只眼(男11例,女3例;平均年龄59.4±8.4岁,无黄斑受累的孔源性视网膜脱离(RRD)行晶状体切除术(RRD组),14例14眼(男10例,女4例;平均年龄(68.4±4.7)岁,伴有黄斑裂孔(MH)行晶状体切除术(MH组),24例24眼(男14例,女10例;平均年龄66.5±7.6岁),29例42眼(男15例,女14例;平均年龄(71.4±11.8岁),无黄斑病变,行白内障手术者(白内障组)。术前和术后1个月采用光学生物测量法测量ACD,并进行组间比较。结果:RRD组ACD(术后ACD减去术前ACD)的平均差值为0.68±0.38 mm, MH组为1.12±0.32 mm, ERM组为1.04±0.56 mm,白内障组为1.00±0.47 mm。RRD组术后ACD较其他组浅。结论:与包括MH患者在内的其他组相比,RRD患者术后ACD较浅,可能是RRD患者近视移位的原因之一。
Changes in the Postoperative Anterior Chamber Depth in Eyes Following Phacovitrectomy in Several Vitreoretinal Diseases
Aim: To investigate the difference in postoperative Anterior Chamber Depth (ACD) following phacovitrectomy depending on the type of the vitreoretinal diseases, measured using optical biometry. Methods: We investigated 14 eyes of 14 patients (11 males, 3 females; mean age 59.4 ± 8.4 years) with Rhegmatogenous Retinal Detachment (RRD) without macular involvement who underwent phacovitrectomy (RRD group), 14 eyes of 14 patients (10 males, 4 females; mean age 68.4 ± 4.7 years) with a macular hole (MH) who underwent phacovitrectomy (MH group), 24 eyes of 24 patients (14 males, 10 females; mean age 66.5 ± 7.6 years) with Epi Retinal Membrane (ERM) who underwent phacovitrectomy (ERM group), and 42 eyes of 29 patients (15 males, 14 females; mean age 71.4 ± 11.8 years) without macular disease who underwent cataract surgery (cataract group). ACD was measured prior to surgery and one month after surgery using optical biometry and was compared between groups. Results: The mean difference in ACD (postoperative ACD minus preoperative ACD) was 0.68 ± 0.38 mm in the RRD group, 1.12 ± 0.32 mm in the MH group, 1.04 ± 0.56 mm in the ERM group, and 1.00 ± 0.47 mm in the cataract group. Postoperative ACD in the RRD group was shallower compared to the other groups. Conclusion: Postoperative ACD in patients with RRD is shallower compared to other groups, including patients with MH, making it one of the suspected causes of myopic shift in patients with RRD.
