概括
反向瞳孔阻塞 (RPB) 是无固定内膜眼镜植入后的常见并发症,可能导致严重的眼睛疾病. YAG激光虹膜切除术是有效的治疗方法,在特定情况下考虑进行外科虹膜切除术.
科学领域:
- 眼科 眼科
- 眼内透镜手术
- 前部部分成像
背景情况:
- 反向瞳孔阻塞 (RPB) 具有后面虹膜曲的特征,可能是由透镜-虹膜门机制引起的.
- 可以导致虹膜擦伤,颜色分散性眼球炎和脑膜炎-眼球炎-脑膜炎综合征.
- 无膜固定眼内透镜 (IOL) 植入是一种常见的眼内透镜脱落或阿法基的手术.
研究的目的:
- 研究无固定内膜眼镜植入的患者逆瞳孔阻塞 (RPB) 的发生率和治疗方法.
- 评估YAG激光虹膜切除术和外科虹膜切除术在治疗RPB中的有效性.
- 确定RPB的危险因素并推预防措施.
主要方法:
- 对41只没有接的内膜眼镜进行了回顾性分析.
- 后续检查包括裂纹灯生物显微镜,眼内压力测量和前部OCT (前部).
- 对RPB存在,相关并发症和治疗结果的评估.
主要成果:
- 在41个眼睛中,有11个眼睛出现逆瞳孔阻塞 (26. 8%).
- RPB与眼内压力升高没有一致的关联,但会带来长期风险.
- 当虹膜可视化充足时,YAG激光虹膜切除术在治疗RPB方面是有效的;对于前腔出血的病例,外科虹膜切除术是必要的.
结论:
- 反向瞳孔阻塞 (RPB) 是无固定内膜眼镜植入后的一个显著并发症.
- YAG激光虹膜切除是RPB的可行的治疗选择,而在特定情况下可能需要手术虹膜切除.
- 对于患有松虹膜或经手术后出现RPB的患者,应考虑采取预防措施,例如手术内虹膜切除或YAG激光虹膜切除.

Angle Closure Glaucoma: Treatment
674
Angle-closure glaucoma, or closed-angle glaucoma, is an eye condition where the iris bulges out and blocks the iridocorneal angle, resulting in a buildup of aqueous humor and increased intraocular pressure. Immediate medical attention is necessary due to the sudden onset of symptoms. The treatment for angle-closure glaucoma includes short-term and long-term approaches. Short-term treatment involves using eye drops like pilocarpine to lower intraocular pressure by increasing aqueous humor...

Glaucoma: Overview
749
Glaucoma is an eye condition characterized by increased intraocular pressure that damages the retina and optic nerve, leading to irreversible blindness if left untreated. The human eye has various components, including the cornea, iris, pupil, lens, and optic nerve. Aqueous humor is secreted by the epithelium of the ciliary body in the posterior chamber and flows through the trabecular meshwork and canal of Schlemm, maintaining normal intraocular pressure. The trabecular meshwork and the canal...
