概括
与非PEX眼相比,接受白内障手术的伪皮眼 (PEX) 显示出更窄的角度和更大的前腔深化. PEX眼睛也经历了显著的超视转移,影响了眼内透镜功率选择.
科学领域:
- 眼科医生 眼科 眼科
- 前段外科手术 前段外科手术
- 生物识别仪表是如何使用的
背景情况:
- 伪脱皮综合征 (PEX) 是二次白内障的常见原因之一.
- PEX可以影响眼睛结构,可能会影响手术结果.
- 了解PEX眼睛在白内障手术后的解剖和折射变化至关重要.
研究的目的:
- 为了比较 phacoemulsification 后的角度形态,前腔深度 (ACD) 和折射预测误差 (PE) 的变化.
- 为了评估伪剥皮 (PEX) 和非PEX眼睛之间的差异.
主要方法:
- 预期病例控制研究涉及60名患者 (30名PEX,30名非PEX).
- 扫描源前段光学连贯性断层扫描用于术前和术后1个月的角度参数 (ACA,AOD,SSA,TISA) 和ACD的测量.
- 折射预测误差 (PE) 用优化的A-常数和凯恩公式计算.
主要成果:
- 与非PEX眼相比,PEX眼的手术前角度 (ACA,AOD,SSA,TISA) 是较窄的 (p<0.05).
- 在手术后的PEX眼睛中观察到更大角度开放和增加ACD深化的趋势 (p<0.05).
- 在PEX眼中发生了一种显著的高视度折射转移,在phacoemulsification后 (p=0.035).
结论:
- 伪皮眼睛有较窄的角度,在白内障手术后显示增加的ACD深化,可能是由于区域松.
- 在PEX眼中显著的超视转移需要在眼内透镜功率计算过程中仔细考虑.
- 这些发现突显了PEX眼睛与非PEX眼睛之间手术结果的重要差异.

Glaucoma: Overview
497
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...

Angle Closure Glaucoma: Treatment
433
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...
