Retinal Morphology in Successfully Treated Macula-Off Retinal Detachment Based on Semiautomated Layer Quantification...

Area of Science:

• Ophthalmology
• Medical Imaging
• Retinal Diseases

Background:

• Retinal detachment (RD) is a serious condition affecting vision.
• Accurate assessment of retinal layer thickness (RLT) is crucial for understanding RD outcomes.
• High-resolution optical coherence tomography (OCT) offers potential for improved RLT evaluation.

Purpose of the Study:

• To evaluate retinal layer thickness (RLT) in patients after successfully treated macula-off retinal detachment (RD).
• To compare the imaging capabilities of high-resolution (HighRes) OCT versus Spectralis OCT for assessing RLT.

Main Methods:

• Prospective, cross-sectional, observational study of 44 patients with macula-off RD.
• HighRes OCT and Spectralis OCT scans were acquired for study eyes and healthy fellow eyes.
• Semiautomatic layer segmentation analysis was performed to measure RLT.

Main Results:

• Inner retinal layers (GCL-IPL and INL) were thicker in study eyes compared to fellow eyes.
• HighRes OCT revealed thinner GCL-IPL and EZ, but thicker INL, OPL-MZ, and PROS-IZ compared to Spectralis OCT.
• HighRes OCT visualized distinct hyperreflective bands not visible with Spectralis OCT.

Conclusions:

• Inner retinal layers are thicker post-RD, and RLT measurements vary between OCT devices.
• HighRes OCT offers superior imaging of outer retinal layers, important for predicting visual outcomes in RD patients.
• HighRes OCT may enhance diagnostic accuracy and clinical management of RD.
