Methods:

This study included 28 eyes of 28 patients (21 M, 7 F) with pseudophakic retinal detachment. Twenty patients (71,4%) underwent combined scleral encircling and PPV operations, and 8 patients (28,6%) underwent only PPV. The time interval between the retinal detachment and the surgery date, macular involvement, visibility of retinal tear, visual acuity, anatomical status and postoperative complications were reviewed retrospectively. Results: Mean age of the patients was 60,35 (SD:13,32) years. Mean follow-up time was 17,37   (SD:7,27) months. Retinal detachment developed after phacoemulsification (n=27) and intracapsular lens extraction (n=1). Two patients had undergone Nd:YAG laser capsulotomy. Macular detachment was recorded in 22 (78,6%) patients. Retinal tears were detected in 25 eyes. Two recurrences of RD in only PPV group and 6 recurrences in combined PPV and scleral encircling group were observed. The anatomical success rate at first operation was 70,0% in combined PPV and scleral encircling group and 75.0% in only PPV group. Among all the patients, at last visit there was only one recurrent retinal detachment which was in the combined PPV and scleral encircling group. The mean time interval between the onset of the symptoms and the surgery date was 71,6 days (SD:9,6) in patients who had recurrent RD; however this time was 22,5 days (SD:12,4) in patients with no recurrent RD. Final anatomical success rate was 96%. Visual acuity improved in 16 eyes (57%), remained the same in 9 eyes (32%) and became worse in 3 eyes (11%).

Take home message:

Pars plana vitrectomy may yield high rates of anatomical and visual success. Scleral encircling seems to have no additional effect in the success rate. Recurrence rate of retinal detachment increases as the time interval between the onset of symptoms and the surgery date increases.
