概括
眼内镜片 (IOL) 的倾斜和分散可能会降低光学质量,但不会显著影响单焦 IOL 的视力敏度. 这表明,中度的错位是可以容忍的,而不会影响患者的视力.
科学领域:
- 眼科医生 眼科 眼科
- 光学工程是指光学工程.
- 生物医学工程 生物医学工程
背景情况:
- 眼内镜片 (IOL) 倾斜和分散是常见的植入后问题.
- 量化IOL错位对视觉结果的影响对于患者满意度至关重要.
研究的目的:
- 为了确定从IOL倾斜和分散的光学退化是否影响视力敏度 (BCVA) 或主观折射.
- 为了将光学质量指标与眼睛中的临床测量与单焦无球体IOL相关联.
主要方法:
- 使用AS-OCT测量了105只眼睛的内视镜位置.
- 创建了个性化的合成眼睛模型来模拟对齐,去中心,倾斜和组合不对齐的场景.
- 使用光学模拟软件计算波面偏差,客观折射和预测视觉敏度.
主要成果:
- 观察到中度的内视镜倾斜 (平均5.19°) 和分散 (平均0.25毫米).
- 模拟失调显著增加了昏迷 (RMS) 和视觉模拟 (VSX) 的下降.
- 尽管光学退化,最佳校正视敏度 (BCVA) 仍然不受影响 (平均0.00 LogMAR),与倾斜或分散无显著相关性.
结论:
- 单焦内射眼镜的适度失调会降低光学质量,但不会影响BCVA.
- 个性化的眼睛模型对于模拟内视眼镜位置的光学效应是有价值的.
- 需要对多焦内膜眼镜设计进行进一步的研究,以了解失调效应.

Open Angle Glaucoma: Treatment
928
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.

Angle Closure Glaucoma: Treatment
1.1K
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...
