Abstract

Introduction: Lacteocrumenasia is a relatively rare postoperative complication of cataract surgery. It is classified as a late-onset type of capsular block syndrome (CBS) and is often accompanied by myopia; however, its mechanism is not clearly understood.

Case presentation: We report a case of a 62-year-old male patient having CBS with myopia. The patient was treated with neodymium-yttrium aluminum garnet (Nd-YAG) laser posterior capsulotomy. We measured and compared the depth of the intraocular lens using anterior segment optical coherence tomography (AS-OCT) before and after laser treatment. Treatment resulted in refraction improvement of more than 1.0 diopters. The intraocular lens depth before and after Nd-YAG laser irradiation had very mild changes of less than 0.05 mm, which did not explain the refractive changes.

Conclusion: Myopia in the early-onset type of CBS is caused by anterior deviation of the intraocular lens; however, the evaluation of this case using AS-OCT suggested that an abnormal intraocular lens position may not be involved in late-onset CBS.

钕钇铝石榴石激光治疗后近视改善的囊状阻滞综合征的前眼球光学相干断层扫描结果。

导言乳糜尿是一种相对罕见的白内障手术后并发症。它被归类为囊袋阻滞综合征（CBS）的晚发类型，通常伴有近视，但其发病机制尚不清楚：我们报告了一例 62 岁男性患者的囊膜阻滞综合征并伴有近视。患者接受了钕钇铝石榴石（Nd-YAG）激光后囊切开术治疗。我们使用前段光学相干断层扫描（AS-OCT）测量并比较了激光治疗前后的眼内晶状体深度。治疗后，屈光度提高了 1.0 个屈光度以上。Nd-YAG激光照射前后的眼内晶状体深度变化非常轻微，小于0.05毫米，这并不能解释屈光度的变化：结论：早发型 CBS 的近视是由眼内晶状体前偏引起的；但使用 AS-OCT 对该病例进行评估后发现，晚发型 CBS 可能与眼内晶状体位置异常无关。

期刊介绍： This peer-reviewed online-only journal publishes original case reports covering the entire spectrum of ophthalmology, including prevention, diagnosis, treatment, toxicities of therapy, supportive care, quality-of-life, and survivorship issues. The submission of negative results is strongly encouraged. The journal will also accept case reports dealing with the use of novel technologies, both in the arena of diagnosis and treatment. Supplementary material is welcomed. The intent of the journal is to provide clinicians and researchers with a tool to disseminate their personal experiences to a wider public as well as to review interesting cases encountered by colleagues all over the world. Universally used terms can be searched across the entire growing collection of case reports, further facilitating the retrieval of specific information. Following the open access principle, the entire contents can be retrieved at no charge, guaranteeing easy access to this valuable source of anecdotal information at all times.
