In cases of persistent pupillary membrane (PPM), the eye is usually slightly microphthalmic and emmetropia or hyperopia is often present, yet severe myopia is reportedly rare. Here we presented a case of PPM complicated by vitreomacular traction syndrome and posterior staphyloma due to severe myopia.
This study involved a 63-year-old female patient who had been diagnosed with bilateral PPM at a local eye clinic and who was subsequently referred to our department for a more detailed examination due to a recent decrease of visual acuity.
Slit-lamp microscopy examination revealed bilateral PPM. The ocular fundus revealed peripapillary conus and myopic change in both eyes. Optical coherence tomography examination revealed no particular abnormalities in the right eye, yet did show findings indicative of vitreomacular traction syndrome in the left eye.
In both eyes, we performed surgical removal of the PPM, phacoemulsification aspiration, and intraocular lens implantation, yet in the patient's left eye, vitrectomy was also performed.
After surgery, the patient's visual acuity improved in both eyes.
The findings in this case show that when required, vitrectomy should be considered based upon the preoperative Optical coherence tomography findings for PPM.
在持续性瞳孔膜（PPM）病例中，眼睛通常略小，常存在正视或远视，但据报道严重近视罕见。在此，我们报告一例PPM合并玻璃体黄斑牵引综合征及因严重近视导致的后巩膜葡萄肿的病例。
本研究涉及一名63岁女性患者，其在当地眼科诊所被诊断为双侧PPM，近期因视力下降而转诊至我科进行更详细检查。
裂隙灯显微镜检查显示双侧PPM。眼底检查显示双眼视盘周围圆锥及近视性改变。光学相干断层扫描检查显示右眼无特殊异常，但左眼显示有玻璃体黄斑牵引综合征的表现。
双眼均进行了PPM手术切除、超声乳化吸除及人工晶状体植入，而患者左眼还进行了玻璃体切除术。
术后患者双眼视力均有改善。
该病例结果表明，对于PPM，必要时应根据术前光学相干断层扫描结果考虑行玻璃体切除术。
