Imaging Studies for Cardiovascular System II:Types of Echocardiography

Echocardiography plays a role in assessing cardiac health and detecting heart conditions, with various types providing critical insights for diagnosis and treatment.
Types of Echocardiography
Transthoracic Echocardiography (TTE)
TTE is the most common type of echocardiogram which involves placing a transducer on the patient's chest, emitting sound waves to create heart images. TTE is invaluable for evaluating the heart's size, structure, and motion, making it particularly useful for diagnosing...
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...

Summary

Intraoperative anterior segment optical coherence tomography (AS-OCT) can assess corneal depth during deep anterior lamellar keratoplasty. Deeper cannula insertion correlates with failed big-bubble formation, suggesting AS-OCT can guide technique for better outcomes.

Area of Science:

  • Ophthalmology
  • Surgical Technology
  • Corneal Surgery

Background:

  • Deep anterior lamellar keratoplasty (DALK) is a surgical procedure for corneal diseases.
  • The big-bubble technique in DALK aims for a successful separation of corneal layers.
  • Accurate assessment of dissection depth is crucial for big-bubble formation.

Purpose of the Study:

  • To assess the feasibility of intraoperative anterior segment optical coherence tomography (AS-OCT).
  • To quantify the corneal depth achieved by the dissecting cannula in DALK.
  • To correlate AS-OCT findings with the success rate of big-bubble formation.

Main Methods:

  • Retrospective case series of 100 keratoconus patients undergoing DALK.
  • Cannula insertion for pneumatic dissection, followed by AS-OCT imaging.
  • Attempted big-bubble formation after AS-OCT assessment.

Main Results:

  • Big-bubble formation achieved in 70% of cases.
  • Average cannula tip depth was 104.3±34.1 μm.
  • Lower mean depths (90.4±27.7 μm) were associated with successful big-bubble formation compared to failed attempts (136.7±24.2 μm).

Conclusions:

  • Sufficient dissection depth is key for successful big-bubble formation in DALK.
  • AS-OCT provides objective intraoperative assessment of cannula depth.
  • AS-OCT may guide cannula repositioning to improve big-bubble success rates.
