Aim: to evaluate the long-term clinical efficacy of the combined (laser plus surgical) minimally invasive technique for rhegmatogenous retinal detachment (RRD). Patients and Methods: treatment results of 41 patients (41 eyes) with local RRD resulting from horseshoe retinal tear were analyzed. All patients underwent wide-field optical coherence tomography (OCT) to localize and measure pathological vitreoretinal adhesions at the site of retinal tear. The next step was a combined laser surgical procedure that included Nd: YAG dissection of pathological vitreoretinal adhesion zone, pneumatic retinopexy (10% C3F8), and barrier laser retinal photocoagulation (LRP) after reattachment. Postoperatively, eye exams were performed after 3 and 7 days, 3, 6, 12, 18, and 24 months. Results: complete reattachment was achieved in 38 patients (92.7%) on day 2 or 3. No reattachment was seen in three patients (7.3%); of them, subretinal gas migration was observed in two patients (4.9%), and partial reattachment was detected in one patient (2.4%) with pseudophakia. Recurrent RRD occurred in 3 patients (7.9%) because of new inferior retinal breaks. In four patients (10.5%), postoperative wide-field OCT of the area of the initial retinal tear performed after reattachment revealed additional pathological vitreoretinal adhesions in the adjacent areas (that were not identified preoperatively). These patients underwent additional LRP around the areas of pathological vitreoretinal adhesions. No recurrent RRDs were seen during follow-up. Conclusion: combined minimally invasive laser surgical technique for local PPDs demonstrated high efficacy (92.7%). This technique was the effective in local retinal detachment resulting from a single superior horseshoe retinal tear in patients with crystalline lens. In some cases, pseudophakia is a technical obstacle to this procedure. Postoperative wide-field OCT is recommended to detect additional pathological vitreoretinal adhesions and to perform LRP around them to reduce the risks of recurrent RRDs greatly.

Objective: To evaluate the efficacy and safety of combined laser-surgical treatment of rhegmatogenous retinal detachment (RRD). Methods: The 32 eyes from 32 patients with a local RRD due to horseshoe tear were enrolled. In addition to standard examination, all patients underwent multispectral laser scanning and wide-field optical coherence tomography (WFOCT) to determine the extention and localization of vitreoretinal tractions (VRT). All patients underwent the combined microinvasive laser-surgical technology of RRD treatment, including YAG-laser excision of the VRT area, pneumatic retinopexy, and barrier laser photocoagulation around the retinal tear after complete retinal attachment (2-3 days). The post-operative examination was performed on days 3 and 7, and in 3, 6, 12, 18, and 24 months. The follow-up period was 2 years. Results: Retinal attachment was achieved in 30 patients (93.8%). The retina did not attach in 2 cases (6.4%) – in a patient with pseudophakia and in a patient who did not follow the recommendations on the proper head position after surgery. The recurrence of retinal detachment occurred in 2 cases (6.7%) as a result of the new tears formation in lower parts of the fundus periphery. The rest of the patients had a stable anatomical and functional result and no recurrence of the disease during the follow-up period. In 2 cases (6.7%) post-operative WFOCT revealed an additional zone of VRT in the adjacent areas to primary retinal tear which could not be visualized when retina was detached. These patients underwent additional barrier laser photocoagulation around revealed areas. No relapses occurred in these patients. Clinically insignificant retinal bleeding was observed in 4 cases (12.5%) during combined laser angiotomy. Full haemostasis was achieved by the 3-mirror contact lens pressure on the eye. Conclusions: The presented technology demonstrates efficiency in 93.8% of cases after a single surgical intervention. The advantage of the technology is the complete elimination of VRT, as the main factor of the disease pathogenesis, which increases the anatomical efficacy of surgery and reduces the risk of recurrence. The micro-invasiveness and low trauma of this type of treatment help to minimize complications and accelerate the rehabilitation of patients. Further study of this technology with a large number of patients and a long follow-up period is required.

Purpose: Assess changes on spectral domain optical coherence tomography (OCT) before, during, and after removal of silicone oil (SO). Methods: Retrospective series of patients who underwent SO tamponade for macula-on rhegmatogenous retinal detachment. OCT scans of the affected eye were taken before, during, and 3 months after SO tamponade. Qualitative assessment of foveal contour and quantitative comparison of OCT parameters (central macular, cube, ganglion cell layer [GCL], and outer retinal thicknesses) were done between 3 time points. Results: Ten eyes of 9 patients were included. Flattening of the foveal contour during SO tamponade was completely reversed after SO removal. Average cube and GCL thicknesses decreased with SO tamponade and increased after SO removal ( P = .01 and P = .02, respectively). Outer retinal thicknesses did not vary among 3 time points ( P = .09). Conclusions: SO tamponade causes foveal flattening and thinning of the inner retinal layers, which is reversible on removal.

Abstract Rhegmatogenous retinal detachment (RRD) is a vision-threatening pathology. Optical coherence tomography (OCT) is useful for evaluating retinal damage and visual prognosis in patients with RRD. Outer retinal undulation (ORU) is often observed on preoperative OCT in RRD. Therefore, we evaluated the correlation between ORU seen on preoperative OCT and pre/post-operative factors in RRD. Patients with RRD (114 eyes) underwent reattachment surgery and ≥ 6 months of follow-up. According to the condition of the macula on preoperative OCT, cases were divided into macula-on RRD (65 eyes) or macula-off RRD (49 eyes). Patients were classified into acute (< 10 days), subacute (10–30 days), and chronic (> 30 days) symptom duration groups. Clinical findings, histories, and relationships with OCT findings, including ORU, were analyzed. Subacute symptom duration was significantly associated with ORU on preoperative OCT (p = 0.001) and had a higher prevalence of ORU (73.7%) than did acute (OR = 4.48) or chronic (OR = 7.467) durations. Ellipsoid zone (EZ) disruption was significantly associated with poorer best-corrected visual acuity (BCVA) than normal EZ integrity at 6 months postoperatively (p = 0.012). ORU on preoperative OCT suggests a 10–30 days morbidity duration in RRD. EZ integrity is useful for predicting postoperative BCVA in macula-off RRD.
