Open Angle Glaucoma: Treatment01:27

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.
Drugs such as carbonic anhydrase inhibitors, α2- and...

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...

Glaucoma: Overview01:25

Glaucoma: Overview

1.7K
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: Therapeutic Uses01:11

Direct-Acting Cholinergic Agonists: Therapeutic Uses

2.0K
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...

Direct-Acting Cholinergic Agonists: Pharmacological Actions

2.6K
Direct-acting cholinergic agonists exert their pharmacological actions by mimicking the effects of acetylcholine on postsynaptic muscarinic receptors to generate parasympathetic responses. These agents elicit a range of physiological responses, including cardiovascular effects. For example, activation of muscarinic receptors induces bradycardia, decreased cardiac output, reduced peripheral resistance, and consequent hypotension. In the eye, stimulation of M3 receptors leads to smooth muscle...

Ophthalmic Drug Delivery Systems

212
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...

Summary
This summary is machine-generated.

Bimatoprost, a glaucoma medication, can cause temporary nearsightedness (pseudomyopia) and focusing spasms. This previously unreported side effect occurred in a young patient using bimatoprost eye drops.

Area of Science:

  • Ophthalmology
  • Pharmacology

Background:

  • Bimatoprost is a widely used topical prostaglandin analogue for glaucoma treatment.
  • Known side effects include eyelash growth, iris pigmentation, and conjunctival hyperemia.
  • Parasympathomimetics are known to cause pseudomyopia, but this effect is not previously reported for bimatoprost.

Observation:

  • A young glaucoma patient initiated treatment with bimatoprost 0.03% topical drops.
  • The patient subsequently developed symptoms suggestive of altered visual function.

Findings:

  • The case demonstrates a clear association between bimatoprost use and the onset of pseudomyopia.
  • Accommodative spasm was also observed in conjunction with the induced pseudomyopia.
  • This represents the first reported instance of bimatoprost precipitating pseudomyopia and accommodative spasm.

Implications:

  • Clinicians should be aware of the potential for bimatoprost to induce transient myopia and accommodative issues.
  • Ophthalmologists should consider bimatoprost-induced pseudomyopia in patients presenting with sudden-onset myopia.
  • Further research may be warranted to elucidate the mechanism behind this adverse effect.
