Resumen
Las gotas para los ojos de atropina a baja dosis controlan eficazmente la exotropía intermitente en niños, mostrando resultados similares a los de las lentes de sobrecorrección. Esto convierte a la atropina al 0,05% en una opción de tratamiento alternativa viable para controlar esta afección.
Área de la Ciencia:
- Oftalmología
- Oftalmología Pediátrica
- Manejo del Estrabismo
Sus antecedentes:
- La exotropía intermitente requiere estrategias de tratamiento no quirúrgicas eficaces.
- Identificar tratamientos con riesgos y efectos secundarios mínimos es crucial para la atención del paciente.
Objetivo del estudio:
- Evaluar la eficacia de las gotas oftálmicas de atropina al 0,05% para controlar la exotropía intermitente en niños.
- Comparar la eficacia de la atropina a baja dosis con las lentes de sobrecorrección.
Principales métodos:
- Un ensayo clínico aleatorizado en el que participaron niños de 2 a 8 años con exotropía intermitente.
- Los participantes fueron asignados a recibir atropina al 0,05% o lentes de sobrecorrección durante 3 meses.
- El control de la desviación se evaluó utilizando escalas de 3 y 6 puntos.
Principales resultados:
- Tanto la atropina al 0,05% como las lentes de sobrecorrección mejoraron significativamente el control de la desviación a los 1 y 3 meses posteriores a la intervención.
- Se observaron mejoras en el control de la desviación a distancia y de cerca en ambos grupos durante el período de 3 meses.
- La atropina a baja dosis demostró mejoras significativas en el control de la desviación de cerca a los 3 meses en comparación con el mes 1.
Conclusiones:
- Las gotas oftálmicas de atropina al 0,05% son eficaces para controlar la exotropía intermitente en niños.
- La atropina a baja dosis muestra una eficacia comparable a las lentes de sobrecorrección.
- La atropina presenta una alternativa de tratamiento potencialmente eficaz para la exotropía intermitente.

01:27Open Angle Glaucoma: Treatment
1.0K
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.

1.9K
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...

01:28Angle Closure Glaucoma: Treatment
1.4K
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...

01:23Ophthalmic Drug Delivery Systems
95
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...

01:30Indirect-Acting Cholinergic Agonists: Pharmacological Actions
1.7K
Indirect-acting cholinergic agonists, also known as anticholinesterases, exert their pharmacological effects by enhancing cholinergic transmission in various body parts, including the neuromuscular junction, autonomic cholinergic synapses, and the brain.
At the neuromuscular junction, these agents work by inhibiting the breakdown of acetylcholine, allowing it to remain bound to the receptor and bind to nearby receptors. This process leads to repetitive firing of the endplate, causing muscle...
