Optical coherence tomography-based positioning regimen for macular hole surgery.

Area of Science:

• Ophthalmology
• Surgical Innovation
• Medical Imaging

Background:

• Macular hole surgery aims for anatomical and visual recovery.
• Postoperative positioning is crucial for successful macular hole closure.
• Standard positioning protocols may not account for individual patient risk factors.

Purpose of the Study:

• To evaluate an optical coherence tomography (OCT)-based postoperative positioning regimen for macular hole repair.
• To determine the efficacy of this regimen in achieving persistent hole closure.
• To assess the impact of risk factors on closure rates with the OCT-guided approach.

Main Methods:

• Retrospective review of 33 patients (35 eyes) undergoing macular hole repair.
• Implementation of a modified prone positioning regimen guided by daily OCT imaging.
• Data collection included visual acuity, hole characteristics (stage, size, chronicity), and OCT findings.
• Analysis of closure rates based on the presence of risk factors like myopic degeneration, chronic, or large holes.

Main Results:

• Overall persistent closure rate of 80% (28 eyes) using the OCT-based positioning regimen.
• Closure rate was 92% in the absence of high-risk factors.
• Closure rates were 85% and 74% in the presence of 2 or 3 high-risk factors, respectively.
• Mean baseline visual acuity was 20/220, improving to 20/135 postoperatively.

Conclusions:

• The OCT-based positioning regimen demonstrates effectiveness in achieving persistent macular hole closure.
• High-risk factors (myopic degeneration, chronic, large holes) can compromise closure and may necessitate modified positioning.
• This tailored approach can optimize outcomes for patients undergoing macular hole surgery.
