概括
异常性视网膜外科手术 (iERM) 通过改变斑点地形,特别是状位置和血管廊距离,改善视力敏度. 这些变化与更好的视觉结果相关,但与变形眼的改善无关.
科学领域:
- 眼科医生 眼科 眼科
- 视网膜外科手术 视网膜外科手术
- 斑点退化症 斑点退化症
背景情况:
- 异形性视网膜膜 (iERM) 可以扭曲斑点地形.
- 了解这些变化对于预测手术结果至关重要.
研究的目的:
- 为了研究iERM移除后黄斑地形的变化.
- 评估这些地形变化与视敏度 (VA) 和变形眼之间的关联.
主要方法:

Angle Closure Glaucoma: Treatment
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...
Open Angle Glaucoma: Treatment
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.
