    Insights

    The Icare-Pro rebound tonometer provides reliable intraocular pressure (IOP) measurements in children, closely correlating with the Goldmann applanation tonometer. This new device offers a viable option for pediatric eye exams without anesthesia.

    Area of Science:

    • Ophthalmology
    • Pediatric Optometry
    • Ocular Diagnostics

    Background:

    • Accurate intraocular pressure (IOP) measurement is crucial for diagnosing and monitoring pediatric glaucoma and other eye conditions.
    • Traditional tonometry methods in children may require anesthesia, complicating clinical practice.
    • The development of non-invasive, anesthesia-free IOP measurement devices is essential for pediatric eye care.

    Purpose of the Study:

    • To compare intraocular pressure (IOP) measurements between the new Icare-Pro rebound tonometer and the hand-held Goldmann applanation tonometer (Perkins).
    • To evaluate the reliability and agreement of the Icare-Pro for pediatric IOP assessment in a clinical setting.
    • To determine if the Icare-Pro can be used effectively in children without the need for general anesthesia.

    Main Methods:

    • A prospective study involving 173 healthy children aged 1-16 years.
    • Three IOP measurements were taken with both the Icare-Pro and Perkins tonometers in a single session.
    • Central corneal thickness, anterior chamber depth, and axial length were also recorded for correlation analysis.

    Main Results:

    • A strong linear correlation (r = 0.87) was found between Icare-Pro and Perkins IOP readings.
    • Icare-Pro measurements were slightly higher (mean difference: 0.26 ± 1.58 mm Hg), with good agreement (ICC = 0.857).
    • Low correlations were observed between IOP and central corneal thickness or age; no correlation with axial length or anterior chamber depth.

    Conclusions:

    • The Icare-Pro rebound tonometer demonstrates good correlation and agreement with the Perkins tonometer for pediatric IOP measurements.
    • The Icare-Pro is a suitable device for routine clinical IOP assessment in children, eliminating the need for general anesthesia.
    • This finding supports the use of the Icare-Pro as a practical and reliable tool in pediatric ophthalmology.

    Hand hygiene

    Asepsis is the practice of preventing or breaking the chain of infection. The nurse employs aseptic techniques to prevent the spread of microorganisms and reduce the risk of diseases. Hand hygiene is the cornerstone of aseptic techniques and is classified into medical and surgical asepsis. Medical asepsis includes hand hygiene and the use of gloves. Surgical asepsis, or the sterile technique, refers to practices that render and keep objects and areas free of microorganisms.

    Pharmacokinetics in Pediatric Patients: Drug Excretion

    In pediatric medicine, understanding the renal function and drug elimination nuances is crucial for administering safe and effective treatments. Newborns, in particular, display markedly slower renal functions than adults, profoundly affecting how drugs are cleared from their bodies. This slower drug clearance requires clinicians to extend the dosing intervals for many medications to prevent drug accumulation and toxicity while ensuring therapeutic efficacy.One key area where these adjustments...

    Muscles of the Forearm that Move the Hand and Fingers

    The muscles of the forearm that move the wrist, hand, and digits are numerous and diverse. They can be classified into two groups based on their location and function — the anterior and posterior compartment muscles.
    Anterior Compartment
    The anterior compartment muscles originate from the humerus. They primarily function as flexors and are also known as flexor muscles. They typically insert on the carpals, metacarpals, and phalanges. The superficial layer includes the flexor carpi...

    Pharmacokinetics in Pediatric Patients: Drug Distribution

    Drug distribution in the pediatric population exhibits unique challenges and considerations due to the physiological differences between children, particularly neonates and infants, and adults. A crucial aspect of pediatric pharmacology is understanding how these differences impact the pharmacokinetics of various drugs, necessitating age-specific dosing strategies to ensure efficacy and safety.Neonates and infants have a higher total body water content, ~75%–90% of their body weight,...

    Pharmacokinetics in Pediatric Patients: Drug Metabolism

    In pediatric care, understanding the nuances of hepatic drug metabolism is crucial, as it significantly differs from that of adults. This divergence is primarily due to the developmental stage of drug-metabolizing enzymes, which affects how medications are processed in the body. In neonates, for instance, the activity of Phase I enzymes—critical for the initial breakdown of drugs—is markedly reduced, functioning at just 20–40% of the levels seen in adults. This reduction poses...
