Wide-feld retinal optical coherence tomography for imaging of peripheral vitreoretinal interface and stratifcation of risk for rhegmatogenous retinal detachment recurrence

Purpose: to evaluate the peripheral vitreoretinal interface changes after combined laser-surgical treatment of local rhegmatogenous retinal detachments revealed by wide-feld OCT. Material and Methods. 21 patients (21 eyes) with local rhegmatogenous retinal detachment localized in the upper half of the fundus were enrolled in this study. All patients underwent a combined laser-surgical treatment, which included 3 steps: 1) Nd: YAG laser excision of the vitreoretinal adhesion zone, determined by wide-feld OCT; 2) pneumatic retinopexy; 3) barrier laser photocoagulation at the edge of the tear after retinal reattachment. All patients underwent OCT of the peripheral vitreoretinal interface to identify areas of pathological vitreoretinal adhesions in the post-operative period. Results. OCT analysis of 21 patients has demonstrated the complete elimination of the traction component in the treatment area. However, vitreoretinal adhesions near the tear area were found in 4 patients. These patients underwent additional barrier laser photocoagulation at zones of pathological vitreoretinal traction. Conclusion. Visualization of
