Local Anesthetics: Common Agents and Their Applications01:23

Local Anesthetics: Common Agents and Their Applications

1.3K
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...

Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

1.7K
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...

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

2.8K
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...

General Anesthesia: Overview01:24

General Anesthesia: Overview

1.2K
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...

Photoreceptors and Visual Pathways01:22

Photoreceptors and Visual Pathways

11.3K
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,...

Area of Science:

  • Ophthalmology
  • Neurology
  • Genetics

Background:

  • Congenital corneal anesthesia is a rare condition affecting corneal sensation from birth.
  • It can lead to severe ocular surface disease and vision impairment.
  • Understanding its varied presentations is crucial for timely intervention.

Purpose of the Study:

  • To describe the clinical spectrum of congenital corneal anesthesia in children.
  • To identify associated neurological and systemic findings.
  • To evaluate treatment outcomes for ocular complications.

Main Methods:

  • Retrospective review of medical records of 40 children diagnosed with congenital corneal anesthesia.
  • Data collected included demographics, clinical characteristics, and ocular findings.
  • Analysis of treatment interventions and visual outcomes.

Main Results:

  • The study included 40 patients, with 70% having bilateral involvement.
  • Common corneal lesions included epithelial defects and sterile ulcers.
  • Associated findings included generalized insensitivity to pain and anhidrosis in 25% of cases.
  • Tarsorrhaphy led to ulcer resolution in most cases, but some eyes had poor visual outcomes after keratoplasty.

Conclusions:

  • Congenital corneal anesthesia requires accurate diagnosis and comprehensive neurological assessment.
  • Prompt management with tear substitutes and tarsorrhaphy is essential for visual rehabilitation.
  • Long-term sequelae can be minimized with early and appropriate care.
