Angle Closure Glaucoma: Treatment01:28

Angle Closure Glaucoma: Treatment

958
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...

Computed Tomography

7.6K
Tomography refers to imaging by sections. Computed tomography (CT) is a non-invasive imaging technique that uses computers to analyze several cross-sectional X-rays to reveal minute details about structures in the body.
The technique was invented in the 1970s and is based on the principle that as X-rays pass through the body, they are absorbed or reflected at different levels. In the technique, a patient lies on a motorized platform while a computerized axial tomography (CAT) scanner rotates...

Open Angle Glaucoma: Treatment

832
In open-angle glaucoma, the iridocorneal angle remains open, but the trabecular meshwork becomes stiff, slowing down the outflow of aqueous humor. This causes a buildup of aqueous humor in the anterior chamber, leading to a sudden increase in intraocular pressure. The treatment for open-angle glaucoma focuses on reducing the elevated intraocular pressure by either decreasing the secretion of aqueous humor or increasing its outflow.
Drugs such as carbonic anhydrase inhibitors, α2- and...

DefinitionComputed Tomography (CT) of the genitourinary (GU) tract is a non-invasive imaging modality that utilizes X-rays and computer processing to generate detailed cross-sectional images of the urinary system, encompassing the kidneys, ureters, bladder, and adjacent structures such as the adrenal glands.PurposeCT scans of the GU tract serve several diagnostic and therapeutic purposes, including:Diagnosis of Urinary Tract Diseases: Detects kidney stones, tumors, cysts, and congenital...

Summary

Operator eye lens doses during computed tomography (CT)-guided interventions are typically low, averaging 22 μSv per procedure. These doses are unlikely to exceed annual limits, and can be estimated using dose length product (DLP) or collar dose.

Area of Science:

  • Medical Physics
  • Radiology
  • Radiation Protection

Background:

  • Computed tomography (CT)-guided interventions involve potential radiation exposure to operators.
  • Estimating operator eye lens dose is crucial for radiation safety in interventional radiology.

Purpose of the Study:

  • To assess operator eye lens doses during CT-guided interventions.
  • To investigate the correlation between dose length product (DLP) and operator dose.
  • To explore methods for estimating eye lens dose in clinical practice.

Main Methods:

  • Prospective measurement of eye lens doses for 16 radiologists over 6 months in 164 CT-guided procedures.
  • Calculation of descriptive statistics and correlation analysis between DLP and measured doses.
  • Evaluation of radioprotective garment effectiveness.

Main Results:

  • Average operator eye lens dose (DEL) was 22 μSv per procedure; collar dose (Hp(10)) was 21 μSv.
  • Mean procedure DLP was 320 mGy cm, with 54% from fluoroscopy (mean 18s exposure).
  • Equations derived: DEL (μSv) = 0.10 × fluoro DLP (mGycm) and DEL (μSv) = 0.7 × collar dose (μSv).

Conclusions:

  • Eye lens doses in CT-guided interventions are generally low, unlikely to exceed the 20 mSv annual limit.
  • Operator eye lens dose can be reliably estimated using the procedure's DLP or collar-level dose.
  • These findings support optimized radiation protection strategies for interventional radiologists.
