Surgical Treatment Of Rhegmatogenous Retinal Detachment Research Articles

Сравнение анатомической и функциональной эффективности радиального эписклерального пломбирования и комбинированной лазер-хирургической технологии при локальной macula-on отслойке сетчатки

Aim: to compare anatomical and functional outcomes of scleral buckling (SB) and combined laser and surgical intervention for focal macula-on rhegmatogenous retinal detachment (RRD). Patients and Methods: surgical outcomes of 84 patients (84 eyes) with focal RRD were analyzed. The study group included 43 patients (43 eyes) who underwent combined laser and surgical treatment for RRD that involved Nd:YAG laser excision of vitreoretinal adhesions followed by pneumoretinopexy and barrier laser photocoagulation. The control group that included 41 patients (41 eyes) was a retrospective sample of patients who underwent radial SB as described. Anatomical (the number of patients with attached retinal after a single surgical intervention and recurrence rate after surgery) and functional efficacy of the surgery were compared over a 2-year follow-up. Results: complete retinal reattachment was reported in 40 patients (93%) in the study group and 39 patients (95.1%) in the control group. Recurrent RD occurred in 3 patients (7.5%) in the study group and 4 patients (9.7%) in the control group over a 2-year follow-up. After 2 years, the final anatomical efficacy was 86% in the study group and 85% in the control group. Notably, no recurrent RD at the site of surgery was reported in the study group. Meanwhile, recurrent RD in the area of the primary retinal tear was reported in 1 patient in the control group. When comparing functional outcomes between the groups, a significant decrease in BCVA accounted for by an increase in astigmatism and spherical equivalent was reported after SB. Conclusions: the combined laser and surgical treatment is not inferior to SB in terms of anatomical efficacy and significantly superior to SB in terms of functional efficacy due to no changes in refractive indices after surgery.

25-gauge vitrectomy and gas for the management of rhegmatogenous retinal detachment.

To evaluate the anatomical and functional results in patients with rhegmatogenous retinal detachment (RRD) who underwent 25-gauge pars plana vitrectomy (PPV) with gas tamponade. A retrospective evaluation of 126 eyes of 126 patients (79 men, 47 women) with RRD who underwent 25-gauge PPV with gas tamponade (13% C3F8 in 87 eyes, 20% SF6 in 39 eyes). 113 patients (89.7%), were operated on under local anaesthesia, 13 patients (10.3%) under general anaesthesia. Macula was detached in 85 eyes (67.5%). 53 eyes had pseudophakic RRD, 73 eyes were phakic. Anatomical success of the primary intervention, change in best corrected visual acuity (BCVA) and incidence of complications were assessed. An average follow-up period is 7.2 months (6-15). With single operation, retinal attachment was achieved in 125 eyes (99.2%); the final anatomical success was 100%. The initial mean BCVA was 0.89 logMar (2.00 to 0.00); at the end of the follow-up period, it improved to 0.23logMAR (1.00 to -0.10), P < 0,0001. During the first post-intervention day, hypotony of the eye below 10 mmHg was observed in 1 patient (0.8%); on the contrary, intraocular pressure was temporarily increased to 25 mmHg and more in 36 patients (28.6%). The surgical treatment of RRD using 25-gauge PPV with expansive gas tamponade renders excellent anatomical results and improvement in BCVA. The incidence of complications and necessity of sclerotomy suturing are low.
