Summary:
Purpose: to assess the diagnostic capabilities of optical coherence tomography (OCT) in En Face mode for planning and conducting surgical navigation using Navilas 577s laser system in patients with central serous chorioretinopa-thy (CSC). Material and Methods. 12 patients (12 eyes) with CSC underwent high-resolution OCT in En Face mode showing morphological changes in the retinal pigment epithelium (RPE). The treatment was performed on Navilas 577s laser device with an individual selection of the necessary energy parameters in the micropulse mode. The follow-up was performed at 1, 3 and 6 months. Results. According to the OCT data in the En Face mode, all patients had morphological changes in RPE, which made it possible to plan and perform computer-assisted laser surgery. 1, 3 and 6 months after treatment, positive dynamics was observed in all cases. Conclusion. The OCT method in En Face mode allows detailed study of architectonics and identifes pathological changes in RPE, which play an important role in the manifestation of CSC, as it enables planning and implementation of topographic-oriented treatment using the Navilas 577s navigation laser system in the areas of RPE detachments.
