[Intraoperative optical coherence tomography in retinal detachment]

Abstract

Background: Using intraoperative optical coherence tomography (iOCT) can be advantageous during macular surgery and lamellar keratoplasty. It is yet unknown if there is a distinct benefit in its application in retinal detachment surgery.

Objective: What can be shown using iOCT during retinal detachment surgery? Can therapeutically relevant decisions be made and do they have a prognostic implication on postoperative results?

Methods: Based on already published (11 patients/eyes) and our own new data (23 patients/eyes),findings by iOCT during retinal detachment surgery are presented.

Results: Outer retinal corrugations are a frequent feature in iOCT in retinal detachment. These corrugations persist during the application of heavy liquids. Even when the retina seems clinically reattached under the use of perfluoroctane, there is significant subfoveal fluid. Using perfluordecaline, there seems to be less subfoveal fluid. In patients with retinal detachment and macula off situation, subclinical full thickness macular holes seem to be more common than assumed. It is unclear if their incidence is influenced by the use of heavy liquids. They appear to have a negative predictive value regarding postoperative visual acuity.

Conclusion: Even if there are no obvious benefits in using iOCT in retinal detachment surgery, this new technique offers deeper insights into the microarchitecture of the detached retina. Further investigations in more patients will show if the use of the iOCT will result in a better prognosis for our patients.
