Summary
Transient cortical blindness is a rare complication following general anesthesia in children undergoing urological surgery. Early diagnosis and risk identification by anesthesiologists are crucial for managing this visual impairment.
Area of Science:
- Anesthesiology
- Pediatric Ophthalmology
- Neurology
Background:
- Transient cortical blindness is a rare complication associated with general anesthesia.
- Urological surgery in children can be complex and carry specific risks.
Purpose of the Study:
- To report a case of transient cortical blindness in a pediatric patient following urological surgery.
- To highlight the importance of recognizing and managing this rare complication.
Main Methods:
- Case report of a 4-year-old boy undergoing general anesthesia for hydrocelectomy.
- Diagnosis confirmed by extinguished flash visual-evoked potential (flash VEP) despite normal ophthalmological examinations.
- Symptoms included blindness and fine motor activity derangements.
Main Results:
- The patient experienced transient cortical blindness post-anesthesia.
- Visual acuity remained at hand motion level at 4 months post-procedure.
- Flash VEP was extinguished, indicating significant visual pathway dysfunction.
Conclusions:
- Cortical blindness is an underrecognized complication in children after surgery.
- Anesthesiologists play a key role in identifying risks and managing such cases.
- Increased awareness among parents and healthcare providers is necessary due to the long-term implications.

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...

Various sedation levels offer significant advantages in facilitating procedural interventions for patients undergoing medical or invasive surgical procedures. These levels span from anxiolysis to general anesthesia, providing a spectrum of sedative effects to cater to specific patient needs. Anxiolysis reduces anxiety and is achieved through minimal sedation, enabling patients to remain awake and responsive while feeling more at ease during the procedure. This level can benefit minor...

01:25Glaucoma: 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...

01:28Angle 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...
