- Title: Evaluating Ultra-Widefield Imaging Utility in the Detection of Treatment-Requiring Peripheral Retinal Tears and Holes

- Purpose: To assess the effectiveness of ultra-widefield (UWF) imaging in detecting peripheral retinal tears and holes that require treatment, compared to the gold standard of indirect ophthalmoscopy with scleral depression.

- Methods:

  - Study Design: Retrospective, observational study.

  - Participants: 198 eyes of 198 patients with acute posterior vitreous detachment (PVD), divided into:

    - Treatment Group: 89 eyes with peripheral retinal tears or holes requiring laser retinopexy.

    - Control Group: 109 eyes with PVD but no retinal tears or holes.

  - Imaging: UWF imaging (Optos Optomap) and indirect ophthalmoscopy with scleral depression.

  - Image Analysis: Two blinded retina specialists reviewed UWF images, with interrater agreement calculated.

- Results:

  - Sensitivity: UWF imaging identified 60 of 89 eyes with treatment-requiring lesions (67.4% sensitivity).

  - Specificity: UWF imaging correctly identified 107 of 109 control eyes (98.2% specificity).

  - Missed Lesions: Lesions anterior to the equator were more likely to be missed (51.2%) compared to those at or posterior to the equator.

  - Interrater Agreement: 87.9% agreement between graders.

  - False Positives/Negatives: False-positive rate was 1.82%, and false-negative rate was 32.6%.

- Key Findings:

  - UWF imaging showed moderate sensitivity and high specificity for detecting treatment-requiring retinal lesions.

  - Lesions in the superior, inferior, and nasal quadrants were more likely to be missed.

  - Pseudophakic eyes (with artificial lenses) had a higher rate of missed lesions (25 of 29 misses).

- Discussion:

  - UWF imaging is useful but has limitations, particularly in detecting lesions anterior to the equator and in pseudophakic eyes.

  - The study highlights the importance of scleral depressed examination as the gold standard for diagnosing retinal tears and holes.

  - UWF imaging can assist in clinical examination but should not replace scleral depression, especially in patients with acute symptoms.

- Limitations:

  - Retrospective study design.

  - Image quality depended on the photographer and patient compliance.

  - The study population had a higher prevalence of retinal lesions than typical clinical practice, potentially inflating sensitivity.

- Conclusion:

  - UWF imaging has moderate sensitivity and high specificity for detecting treatment-requiring retinal tears and holes.

  - It should be used as an adjunct to, not a replacement for, scleral depressed examination.

  - A 360-degree scleral depressed examination remains the gold standard for evaluating patients with acute symptoms.
