To elucidate risk potentiality of frontline radiotherapy associated cataracts in primary ocular adnexal mucosa-associated lymphoid tissue lymphoma (OAML).
Data from eight consecutive patients of 41 total OAML patients who had undergone cataract surgery after frontline radiotherapy were analyzed.
The median patient age was 46 years (range, 36 to 69 years). The median total radiation dose was 3,780 cGy (range, 3,060 to 4,500 cGy), and the mean duration from radiation irradiation to cataract surgery was 36.60 ± 8.93 months. Preoperative lens opacification was primarily at the posterior lens subcapsule, and best-corrected visual acuity (BCVA) was 0.43 ± 0.21. Patients underwent the phacoemulsification surgical procedure with posterior chamber intraocular lens insertion. The average BCVA improved to 0.90 ± 0.14 after cataract surgery. Two patients underwent posterior continuous curvilinear capsulorhexis, and one had posterior capsule rupture. For posterior capsule opacification (PCO), three patients received Nd:YAG laser posterior capsulotomy after the initial surgery, and one patient is currently under consideration for laser posterior capsulotomy.
Radiotherapy increased posterior subcapsule opacification at a relatively young age in primary OAML. Phacoemulsification was a manageable procedure without severe complications, and final visual outcomes were good. However, because after-cataracts progressed earlier than did senile cataracts, close follow-up should be considered for PCO management.
阐明原发性眼附属器黏膜相关淋巴组织淋巴瘤(OAML)一线放疗相关白内障的潜在风险。
分析了41例接受一线放疗后行白内障手术的OAML患者中连续8例患者的数据。
患者中位年龄为46岁(范围36至69岁)。中位总辐射剂量为3780 cGy(范围3060至4500 cGy),从放疗至白内障手术的平均时长为36.60±8.93个月。术前晶状体混浊主要位于晶状体后囊下,最佳矫正视力(BCVA)为0.43±0.21。患者接受了超声乳化手术并植入后房型人工晶状体。白内障手术后平均BCVA提高至0.90±0.14。2例患者进行了后连续环形撕囊,1例发生后囊破裂。对于后囊混浊(PCO),3例患者在初次手术后接受了Nd:YAG激光后囊切开术,1例患者目前正在考虑进行激光后囊切开术。
放疗使原发性OAML患者在相对年轻时出现后囊下混浊。超声乳化是一种可控制的手术,无严重并发症,最终视力结果良好。然而,由于后发性白内障比老年性白内障进展更早,应考虑密切随访以管理PCO。
