まとめ
経口シチコリン溶液は、12ヶ月にわたり開角緑内障患者の網膜機能と神経伝導を改善した。この治療は視覚路の接続性を高め、視野欠損を改善する可能性がある。
科学分野:
- 眼科学
- 神経科学
- 薬理学
背景:
- 開角緑内障(OAG)は進行性の視神経疾患である。
- 視覚路の機能不全はOAGの特徴である。

研究 の 目的:
- OAG患者における経口シチコリン溶液の網膜機能および神経伝導への影響を評価すること。
- 治療後12ヶ月にわたる視覚路の変化を評価すること。
- シチコリンの神経調節効果の可能性を探求すること。
主な方法:
- 29名のOAG患者を対象とした無作為化、前向き、二重盲検試験。
- シチコリン経口溶液(500 mg/日)またはプラセボを12ヶ月間投与。
- 視野(VF)、網膜電図(PERG)、視覚誘発電位(VEP)、網膜視床路時間(RCT)、およびDTI-MRIを評価した。
主要な成果:
- シチコリン群では、PERGおよびVEPの振幅に有意な増加が見られた。
- シチコリンにより、PERG、VEPの潜時、およびRCTの有意な改善が観察された。
- VEP潜時の短縮は、VFの平均偏差の改善と相関していた。
- RCTの変化は、視覚路構造におけるDTI-MRIの測定値と関連していた。

Open Angle Glaucoma: Treatment
951
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.

Direct-Acting Cholinergic Agonists: Therapeutic Uses
1.5K
Direct-acting cholinergic agonists have many therapeutic uses in various medical fields. Choline esters, including acetylcholine, have limited clinical utility due to their non-selectivity and short duration of action. Still, acetylcholine and carbachol are applied topically during ophthalmologic surgery to induce miosis. Pilocarpine, a muscarinic and ganglionic stimulator, effectively treats open-angle glaucoma and alleviates xerostomia and dry mouth caused by radiotherapy or Sjögren...

Cognitive Enhancers: Cholinesterase Inhibitors and NMDA Receptor Antagonists
535
Cognitive enhancers, also known as "smart drugs," are substances used to enhance memory, mental alertness, and concentration. These can be natural or synthetic and improve cognition in conditions like Alzheimer's disease (AD) and other neurodegenerative diseases. Some common examples include caffeine, amphetamines, methylphenidate, modafinil, arecoline, donepezil, vortioxetine, and piracetam. These enhancers work on the principle of synaptic plasticity and altered circuit function.

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...

Glaucoma: Overview
1.2K
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...

Direct-Acting Cholinergic Agonists: Pharmacokinetics
1.8K
Direct-acting cholinergic agonists, such as synthetic choline esters and naturally occurring alkaloids, exert their effects by enhancing the actions of acetylcholine and stimulating the parasympathetic nervous system. Synthetic choline esters share structural similarities with acetylcholine. For example, they have a positively charged quaternary ammonium or onium group, contributing to their hydrophilic characteristics. As a result, they are poorly absorbed in the body through oral...
