Summary
Cannabinoids may treat glaucoma by lowering eye pressure and protecting retinal cells. This review explores the endocannabinoid system
Area of Science:
- Ophthalmology and Neuroscience
Background:
- Glaucoma causes irreversible blindness through retinal ganglion cell (RGC) loss.
- Elevated intraocular pressure (IOP) is a key modifiable risk factor for glaucoma progression.
Purpose of the Study:
- To review the role of cannabinoids in glaucoma treatment.
- To discuss the endocannabinoid system's (ECS) potential in managing glaucoma pathology and neuroprotection.
Main Methods:
- Literature review of studies on glaucoma pathophysiology.
- Analysis of cannabinoid signaling alterations in glaucoma.
- Examination of ECS-targeting agents for glaucoma therapy.
Main Results:
- Exogenous cannabinoids demonstrate IOP-lowering effects.
- ECS modulation shows potential for neuroprotection in glaucoma.
Conclusions:
- The ECS presents a promising therapeutic target for glaucoma.
- Cannabinoids and novel ECS agents warrant further investigation for glaucoma treatment.

Open Angle Glaucoma: Treatment
1.1K
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
1.6K
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...

Angle Closure Glaucoma: Treatment
1.6K
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...

Ophthalmic Drug Delivery Systems
211
Ophthalmic drug delivery faces major limitations due to poor absorption across the corneal membrane. This process is primarily driven by diffusion and is influenced by two main factors: the physicochemical properties of the drug and tear drainage. Most ophthalmic drugs, such as pilocarpine, epinephrine, atropine, and local anesthetics, are weak bases. They are typically formulated at an acidic pH to enhance chemical stability. However, this leads to high ionization, reducing their ability to...

G Protein-coupled Receptors
19.5K
G Protein-Coupled Receptors or GPCRs are membrane-bound receptors that transiently associate with heterotrimeric G proteins and induce an appropriate response to sensory stimuli such as light, odors, hormones, cytokines, or neurotransmitters.
GPCRs are also called heptahelical, 7TM, or serpentine receptors, and consist of seven (H1-H7) transmembrane alpha-helices that span the bilayer to form a cylindrical core. The transmembrane helices are connected by three extracellular loops and three...

Ligand-Gated Ion Channel Receptor: Gating Mechanism
4.7K
Ligand-gated ion channels are transmembrane proteins that play a vital role in intercellular communication and functions of the nervous system. They allow the influx of ions across the membrane once the neurotransmitter binds, allowing the subsequent transmission of electrical excitation across the neurons. Other ligand-gated ion channels, like the γ-aminobutyric acid (GABA) receptor, permit anions like chloride into the cells on the binding of the GABA molecule. Their entry into the cell...
