- 评估RGP镜头磨损对最佳校正视敏度 (BCVA) 和双眼功能的影响.
- 根据折射误差的类型和同时存在的眼部疾病的存在来比较结果.
主要方法:
- 一项对50名装有RGP镜头的幼儿进行回顾性研究.
- 纳入标准:超高的视障,近视 (≤-9.00D),高的光标 (≥2.00D),高的无光度 (≥3.00D),有或没有眼睛病变.
- 在RGP穿戴 (≥6个月) 之前和之后分析BCVA变化和双眼功能 (沃斯4点测试,立体急性).
主要成果:
- 在RGP磨损后,BCVA显著改善,从1.10到0.30 logMAR (p < 0.001).
- 56%的孩子达到6/12或更好的BCVA;17人表现出良好的双眼功能.
- 在超高近视 (50%),高合性 (67%) 和纯高无光度 (50%) 中,观察到双眼功能良好的最高率.

01:16Focusing of Light in the Eye
5.3K
Light rays enter the eye through the cornea, a transparent dome-shaped tissue that is the eye's outermost layer. The cornea bends or refracts, light rays traveling to the pupil. The shape of the cornea determines how much of the light is bent and whether the image will be focused correctly on the retina at the back of the eye. Once the light has passed through both refraction layers, it converges into a single focal point onto a small area. This is where photoreceptors start transforming...

01:28Angle 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...

01:27Open Angle Glaucoma: Treatment
953
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.
