Summary
Methylphenidate (MTX) can increase intraocular pressure (IOP) in children, especially those with pre-existing eye conditions. Careful monitoring and alternative treatments like atomoxetine are crucial for managing attention deficit hyperactivity disorder safely.
Area of Science:
- Ophthalmology
- Pediatrics
- Pharmacology
Background:
- Methylphenidate (MTX) is a central nervous system stimulant used for Attention Deficit Hyperactivity Disorder (ADHD).
- Existing literature suggests a potential link between MTX and elevated intraocular pressure (IOP).
- Nuanced risk factors for MTX-induced IOP elevation require further investigation.
Observation:
- A 6-year-old girl with ADHD and a family history of eye conditions developed increased IOP after 12 days of MTX treatment.
- The patient presented with high hyperopia, a potential contributing factor to IOP elevation.
- MTX was discontinued due to the observed increase in IOP.
Findings:
- The patient's IOP normalized after MTX discontinuation.
- Transitioning to atomoxetine resulted in normalized IOP and improved attention duration.
- High hyperopia may exacerbate the effect of MTX on IOP in susceptible pediatric patients.
Implications:
- This case highlights the importance of considering pre-existing eye conditions and family history when prescribing MTX in pediatric ADHD patients.
- Close monitoring of IOP is recommended for children on MTX, particularly those with risk factors like hyperopia.
- Individualized treatment strategies and careful patient selection are essential for safe and effective ADHD management.

01:27Open Angle Glaucoma: Treatment
413
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.

Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder characterized by persistent inattention, hyperactivity, and impulsivity. It affects approximately 5-8% of children globally, with around 60-70% of cases persisting into adulthood. ADHD has significant implications for educational attainment, social interactions, and occupational success.

710
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
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...

01:28Adrenergic Agonists: Mixed-Action Agents

Mixed-action adrenergic agonists, like ephedrine and pseudoephedrine, directly and indirectly affect adrenergic receptors. These agents stimulate adrenoceptors and indirectly release stored neurotransmitters, amplifying the adrenergic response.
Ephedrine and pseudoephedrine lack a catecholamine group, making them less susceptible to degradation by metabolic enzymes. They have increased oral bioavailability and lipophilicity, resulting in a longer duration of action. Their response is reduced by...

Adrenergic agonists have diverse therapeutic uses across various medical conditions and emergencies.
Emergency and Intensive Care Unit (ICU) applications: Pressor agents increase blood pressure, heart rate, and contractility in shock and organ failure situations. Dopamine can induce vasodilation and stimulate adrenoceptors. Endogenous catecholamines are effective in treating cardiogenic shock. α2-agonists like clonidine can reverse anesthesia-induced hypertension.
