评估儿童白内障手术合并人工晶状体(IOL)植入术后中央黄斑厚度(CMT)和中央凹下脉络膜厚度(SFCT)的谱域光学相干断层扫描(SD-OCT)变化。
这是纵向的,prospective,介入研究,包括90例接受白内障摘除人工晶状体植入术的儿科患者。连续SD-OCT扫描在术后第1天,1个月,和3个月的随访。每次访视时测量CMT和SFCT。
在手术后1个月(从199.3μm到210.04μm),CMT有统计学意义的增加,在3个月内下降(202.70μm,P=0.0001)。在SFCT的情况下,在3个月的随访中观察到持续增加(基线:296.52μm;1个月:309.04μm;3个月:319.03μm,P=0.0001)。外伤性白内障组比非外伤性白内障组表现出更明显的CMT和SFCT变化。在进行原发性后囊切开术(PPC)的患者与未进行后囊切开术的患者之间,关于这些参数没有观察到显着差异。研究组患者均未出现黄斑囊样水肿。这些与后段相关的解剖学变化不影响最终的视觉结果。
白内障手术可诱导儿科患者黄斑和脉络膜潜在的炎症改变。这种变化在创伤相关病例中更为明显;然而,它们的重要性不足以影响视觉结果。同样,PPC的额外手术步骤不会引起明显的解剖或功能变化。
To evaluate the central macular thickness (CMT) and subfoveal choroidal thickness (SFCT) changes on spectral domain optical coherence tomography (SD-OCT) after cataract surgery with intraocular lens (IOL) implantation in a pediatric population.
This was a longitudinal, prospective, interventional study which included 90 pediatric patients who underwent cataract extraction with IOL implantation. Serial SD-OCT scans were done at postoperative day 1, 1-month, and 3-month follow-up. CMT and SFCT were measured at each visit.
A statistically significant increase in CMT was noted at 1 month (from 199.3 μm to 210.04 μm) post surgery, which declined over a 3-month period (202.70 μm, P = 0.0001). In case of SFCT, a constant increase was observed for over 3 months of follow-up (baseline: 296.52 μm; 1 month: 309.04 μm; and 3 months: 319.03 μm, P = 0.0001). The traumatic cataract group showed more pronounced changes in CMT and SFCT than the non-traumatic cataract group. No significant difference was observed regarding these parameters between those who underwent primary posterior capsulotomy (PPC) versus those who did not. None of the patients in the study group developed cystoid macular edema. These posterior segment-related anatomical changes did not affect the final visual outcomes.
Cataract surgery induces potential inflammatory changes in the macula and choroid in pediatric patients. Such changes are more pronounced in trauma-related cases; however, they are not significant enough to affect the visual outcomes. Similarly, the additional surgical step of PPC does not induce significant anatomical or functional changes.
