概括
毒素-A (BTX-A) 注射用于良性基本白发作和半面可以改变角膜测量并影响眼内透镜功率计算. 建议在BTX-A处理后重复测量以准确确定IOL功率.
科学领域:
- 眼科医生 眼科 眼科
- 神经学 神经学
背景情况:
- 良性基本 (BEB) 和半面 (HFS) 是神经疾病,导致 involuntary 眼收缩.
- 毒素-A (BTX-A) 注射是这些疾病的常见治疗方法,但它们对眼睛参数的影响尚未完全理解.
研究的目的:
- 评估BTX-A治疗对BEB和HFS患者的角膜拓学,眼睛生物测量和角膜测量的影响.
- 为了评估BTX-A注射后眼内透镜 (IOL) 功率计算的变化.
主要方法:
- 一项涉及33名BEB患者和5名接受BTX-A注射的HFS患者的研究.
- 在治疗前和治疗后一个月,测量了折射误差,撕裂分解时间 (TBUT),角膜地形 (K1,K2,Km) 和眼部生物量 (轴长,前腔深).
- 预期的吸血性IOL功率是使用标准公式 (SRK-T,Holladay,Hoffer-Q,Haigis) 来计算的.
主要成果:
- 治疗BTX-A导致平均角膜功率 (Km) 和前腔深度 (ACD) 显著增加.
- 通过SRK-T,Holladay和Hoffer-Q公式计算的预期血液中流的IOL功率显著下降.
- 在注射后,撕裂分解时间 (TBUT) 显著减少.
结论:
- 注射BTX-A可以改变肌肉测量和ACD值,可能会影响IOL功率计算.
- 该研究强调需要仔细考虑这些变化,建议在释后重复测量,以便在BEB和HFS患者中准确确定IOL功率.

Accessory Structures of the Eye
1.5K
Optical perception, or vision, is an extraordinary sense dependent on converting light signals received via the ocular organs. These organs, known as eyes, are securely positioned within the bony cavities of the skull, called orbits. The orbits serve a dual purpose: a protective shield for the ocular globes and a stable attachment point for the soft ocular tissues. The eye's external protective mechanisms include the eyelids, which are edged with lashes that act as a barrier against foreign...

Open Angle Glaucoma: Treatment
408
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.

Glaucoma: Overview
528
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...

Focusing of Light in the Eye
2.6K
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...

Angle Closure Glaucoma: Treatment
454
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...
