Angle Closure Glaucoma: Treatment

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...

Endoscopic Procedures III: Video Capsule Endoscopy

Endoscopic Procedures III: Video Capsule Endoscopy

Capsule endoscopy, or wireless or video capsule endoscopy, is a diagnostic procedure for examining the entire gastrointestinal tract. Patients swallow a capsule about the size of a vitamin tablet. The capsule is equipped with a transmitter, a battery, an LED light source, and a color video camera to capture images throughout the gastrointestinal tract. This procedure is particularly useful for diagnosing conditions such as Crohn's disease, ulcerative colitis, tumors, polyps, ulcers, unexplained...

Endoscopic Procedures I: Esophagogastroduodenoscopy

Endoscopic Procedures I: Esophagogastroduodenoscopy

An Esophagogastroduodenoscopy (EGD) is a diagnostic procedure in which an endoscopist uses a flexible, lighted endoscope to visualize the upper gastrointestinal (GI) tract. The procedure includes visualizing the oropharynx, esophagus, stomach, and the first part of the small intestine, the duodenum.
During an EGD, the endoscope can be used to:

Endoscopic Procedures V: ERCP

Endoscopic Procedures V: ERCP

Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Endoscopic Procedures IV: Sigmoidoscopy and Laproscopy

Sigmoidoscopy and laparoscopy are distinct medical procedures that enable physicians to internally inspect different parts of the GI tract. Although they serve different purposes, each is essential for diagnosing and, in some cases, treating various medical conditions.
Sigmoidoscopy
Sigmoidoscopy is a diagnostic procedure that uses a flexible sigmoidoscope equipped with a light source and camera to examine the rectum and sigmoid colon. The procedure involves inserting the tube through the anus...

Summary

The oculocardiac reflex, a response to eye stimulation, can cause severe arrhythmia. This reflex can occur during endoscopic sinus surgery, not just eye surgery.

Area of Science:

Ophthalmology
Cardiology
Otorhinolaryngology

Background:

The oculocardiac reflex is a well-documented phenomenon triggered by stimulation of the eyeball or orbital tissues.
It typically involves manipulation of extraocular muscles during ocular surgery.
Previous cardiac evaluations are crucial to rule out pre-existing heart conditions.

Observation:

A case of severe arrhythmia was observed during endoscopic sinus surgery.
The arrhythmia was attributed to the oculocardiac reflex.
The reflex was triggered by stimulation of orbital tissue due to injury of the lamina papyracea.

Findings:

The oculocardiac reflex can be induced by surgical procedures beyond ocular surgery, such as endoscopic sinus surgery.
Injury to the lamina papyracea during endoscopic sinus surgery can stimulate orbital tissue and elicit the reflex.
The patient had no prior cardiac abnormalities, highlighting the reflex as the cause of arrhythmia.

Implications:

Endoscopic sinus surgery carries a potential risk of inducing the oculocardiac reflex and subsequent arrhythmia.
Awareness of this risk is important for surgeons performing endoscopic sinus surgery.
This finding expands the known triggers for the oculocardiac reflex beyond traditional ocular procedures.
