ABSTRACTImplants are essential for the repair of retinal detachments. The implant buckles the wall of the eye and apposes the detached retina with the choroid, thus restoring light sensitivity to the retina. The scleral buckling also relieves traction on the retina from a shrinking vitreous body. The implant materials most commonly used are solid silicone rubber and silicone sponges, but both types have some disadvantages. A poly(hydroxyethyl acrylate-co-methyl acrylate) hydrogel implant with improved properties of softness and antibiotic absorption is also available for retinal detachment surgery. Proliferative vitreoretinopathy involves various conditions of retinal detachment complicated by vitreous fibrosis, which, after vitrectomy, may be treated with intraocular injection of fluids that support the retina against the choroid. For conditions requiring a long-term implant, silicone oil although controversial is the material of choice. Many other substances have been investigated but none better has yet been found.

Purpose. To evaluate the effectiveness of using platelet-rich plasma (PRP) as a blocking of retinal rupture without the use of silicone and gas tamponade (SF6, C2F6, C3F8). Material and methods. In the period from September 2020 to February 2021, in the conditions of the BUZ UR "Republican Ophthalmological Clinical Hospital" of the Ministry of Health of the Udmurt Republic, 12 patients aged 48 to 70 years were treated with a diagnosis of rhegmatogenous retinal detachment with the presence of peripheral tears. In 12 patients, breaks of different localization were revealed - in eight, in the upper half, in four in the lower half of the retina. Myopia was identified as a risk factor in 6 patients. Visual acuity before surgery ranged from 0.001 to 0.3. The operations were performed under retrobulbar anesthesia. In all cases, a subtotal 25Ga vitrectomy was performed with the removal of the posterior hyaloid membrane (PCM) to the extreme periphery and careful excision of the vitreous body in the area of retinal ruptures. The next stage is the introduction of PFOS to the level of the retinal defect, replacing it with air and draining the SRF, minimal endolaser coagulation of the retina around the retinal ruptures. At the final stage of the operation, platelet-enriched plasma was sequentially multi-layered on the rupture area until the rupture was blocked with a PRP layer. In all patients, the operation was completed with air endotamponade. Results. On the first day, visualization of the fundus was reduced in all patients due to air tamponade. By the 4th day, plasma enriched with platelets in the form of a gray film was determined on the surface of the retina in the zone of rupture, the resorption of which occurred within 2 weeks. The duration of the air tamponade averaged 7-10 days. Retinal adhesion in the early postoperative period was achieved in all patients. In 6 patients with the introduction of PRP, a picture of mild uveitis was observed, which was stopped within 1-3 days against the background of anti-inflammatory treatment. No other complications were observed. In the late postoperative period (after 2 weeks), complete retinal adhesion was maintained in 12 patients, visual acuity was 0.05-0.2. According to the data of the performed echography, phosphene and the study of the visual fields, no pathological changes were revealed. In the long-term postoperative period, complete retinal adhesion was noted in 10 patients, visual acuity with correction ranged from 0.3 to 0.5. At different times after the operation, a relapse of retinal detachment occurred in two patients. In one patient with multiple degenerative changes in the periphery of the retina, a relapse of detachment was revealed 2 months after surgery. In all likelihood, the relapse was associated with the emergence of new ruptures in the dystrophy zone and the presence of a proliferative process. In another patient, a relapse of retinal detachment was also observed 4 months after surgery due to the progression of PVR (post-traumatic retinal detachment). All patients with a relapse of retinal detachment within 1–2 days after the detection of a relapse underwent a second operation with revision of the vitreous cavity and subsequent silicone tamponade, which led to complete adhesion of the retina. Conclusion. ROS surgery by subtotal vitrectomy with blocking of retinal tears with platelet-rich plasma and air tamponade is an effective one-stage technique that minimizes the traumatic effect of the operation, reduces postoperative inflammatory complications, and also reduces economic losses.

(1) Background: The aim of the study was to test the hypothesis that the antioxidant status in the vitreous body of eyes, which had been vitrectomized due to rhegmatogenous retinal detachment (RRD) with or without proliferative vitreoretinopathy (PVR), is higher than in eyes vitrectomized due to other retinal diseases. (2) Methods: four patient groups were analyzed: 22 eyes of patients with RRD without PVR, 27 eyes with RRD and PVR, 22 eyes with macular hole (MH) and 10 eyes with epiretinal membrane (ERM). Spectrophotometric methods were used to determine the total antioxidant status (TAS) values as well as superoxide dismutase (SOD) and glutathione reductase (GR) activities in the vitreous fluid samples. (3) Results: no significant differences in TAS values and antioxidant enzyme activities were observed among patient with RRD with and without PVR and with MH and ERM. The longer the duration of RRD leading to PVR and better postoperative visual acuity, the higher the TAS level. No significant differences were found between “macula on” and “macula off” subgroups within the RRD group and the RRD combined with PVR group. (4) Conclusions: The preliminary results do not support the thesis that the antioxidant status of vitrectomized eyes is different in patients with RRD with or without PVR in comparison to patients with MH and ERM. In patients with RRD, PVR presence and detached macula do not affect the values of TAS, SOD and GR in the vitreous fluid. The duration of the disease influences TAS in the vitreous in eyes with RRD complicated with PVR.

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.
