    Insights

    Therapeutic soft contact lenses effectively treated a child with congenital corneal anesthesia and recurrent epithelial breakdown, improving vision and preventing scarring. Continued remission was observed after lens discontinuation.

    Area of Science:

    • Ophthalmology
    • Corneal Disease
    • Pediatric Eye Care

    Background:

    • Congenital corneal anesthesia presents a challenge in pediatric ophthalmology.
    • Recurrent epithelial disruption can lead to significant visual impairment and corneal scarring.

    Observation:

    • A 6-year-old boy presented with poor visual acuity and diffuse corneal epithelial disruption.
    • Corneal sensation was significantly reduced, confirmed by aesthesiometry.
    • Standard treatments like artificial tears and eyelid taping were ineffective.

    Findings:

    • Therapeutic soft contact lenses improved visual acuity to 6/12 (20/40) in the right eye and 6/6 (20/20) in the left eye.
    • Contact lens use arrested the epithelial breakdown.
    • The corneal epithelium remained intact for a year after contact lens discontinuation.

    Implications:

    • Early intervention with therapeutic contact lenses can halt the cycle of epithelial breakdown in congenital corneal anesthesia.
    • This treatment can prevent long-term complications such as corneal scarring.
    • Maintaining remission after treatment cessation suggests a potential for lasting recovery.

    Glaucoma: Overview01:25

    Glaucoma: Overview

    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: Treatment01:28

    Angle Closure Glaucoma: Treatment

    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...

    Local Anesthetics: Common Agents and Their Applications

    Local anesthetics (LAs) are commonly used for various applications in medical and dental procedures. Some of the common agents used are cocaine, lidocaine, and bupivacaine.
    Cocaine is an ester of benzoic acid and methylecgogine. It is used to anesthetize and vasoconstrict locally. Currently, it is used primarily for topical applications. It is beneficial for surgeries on the upper respiratory tract, providing anesthesia and shrinking the mucosa. Cocaine in the form of cocaine hydrochloride is...

    Local Anesthetics: Clinical Application as Surface, Infiltration, and Conduction Block Anesthesia

    Depending on the target organ, local anesthetics (LAs) can be administered via various routes. In surface anesthesia, LAs are applied directly to the surface of the skin or mucous membranes. It is widely used for topical skin numbing before venipuncture or minor surgical procedures. Commonly used surface local anesthetics are lidocaine or benzocaine sprays or creams. Surface anesthesia occurs within 5 minutes and lasts for about 60 minutes. One of the main disadvantages of topical anesthesia is...
    Photoreceptors and Visual Pathways01:22

    Photoreceptors and Visual Pathways

    At the molecular level, visual signals trigger transformations in photopigment molecules, resulting in changes in the photoreceptor cell's membrane potential. The photon's energy level is denoted by its wavelength, with each specific wavelength of visible light associated with a distinct color. The spectral range of visible light, classified as electromagnetic radiation, spans from 380 to 720 nm. Electromagnetic radiation wavelengths exceeding 720 nm fall under the infrared category, whereas...
    General Anesthesia: Overview01:24

    General Anesthesia: Overview

    Anesthesia is a medical procedure that uses drugs for CNS suppression to enable painless surgeries and procedures. The selection of anesthetics is influenced by their pharmacokinetic properties, side effects, and patient characteristics. Various types of anesthesia include general, local, regional, spinal, and inhalational.
    General anesthesia induces unconsciousness in the whole body, while the others target specific areas or sensations. It is administered to minimize adverse effects, maintain...
