Peritomy-sparing scleral buckle.

ABSTRACT:

Purpose

To introduce a modified technique for encircling circumferential scleral buckling without peritomy thorough a small conjunctival opening for the repair of uncomplicated rhegmatogenous retinal detachment (RD).

Methods

This technique was performed in 10 eyes of 10 patients with primary rhegmatogenous RD who underwent encircling circumferential scleral buckling without peritomy. Transconjunctival traction sutures were placed in four rectus muscles. After transconjunctival location of the retinal break, a 5- to 6-mm radial conjunctival incision was performed in 4 quadrants without cutting the limbal conjunctiva-Tenon's capsule. A 240-silicone band in scleral belt loops was used for an encircling circumferential buckle. After drainage and cryopexy, SF6 was used for tamponade. The incision was closed via layered closure only ocassionally.

Results

Primary attachment success of 100% was achieved by single procedure. The intraoperative and postoperative complications observed included subconjunctival hemorrhage observed in 5 (50%) of eyes. These disappeared in the postoperative period.

Conclusions

Minimal conjunctival incision in scleral buckle without peritomy can achieve excellent anatomical success in patients with rhegmatogenous RD without distorting ocular surface anatomy. This is the first description of technique preserving corneal limbus anatomy that could convert buckling surgery to more attractive option for retina surgeons.

Project description:IntroductionScleral buckling (SB) tends to be more challenging and time-consuming for compared to the pars plana vitrectomy for repairing rhegmatogenous retinal detachments (RRDs). This study characterizes a novel and simplified technique for SB.MethodsIn this single-masked randomized interventional study, patients with RRDs who were eligible for SB were randomly assigned to either the standard (S) or modified (M) technique of SB. In the modified approach, neither intraoperative break localization nor cryopexy or subretinal fluid drainage was done. A large tire (276/279) was placed where preoperative retinal breaks had been localized with a 240 encircling band placed for support of the remaining retina. Patients were followed for 12 months and the primary outcomes were differences between the surgical groups in operative time, anatomical success, visual acuity, and complication rate.ResultsThirty-six eyes were included in the study (18 in each arm). There were no differences in baseline patient demographics or characteristics including gender, age, lens and macular status, preoperative vision, and symptom duration. The mean length of surgery was 72.2 ± 13.2 and 56.2 ± 9.5 min in groups S and M, respectively (P = 0.001). Complete retinal reattachment at the end of month 12 after single surgery was 80.6% overall; 77.8% (14/18) in group S and 83.3% (15/18) in group M (P > 0.999). After 12 months, both groups achieved similar final best-corrected visual acuity (BCVA): 0.26 ± 0.23 and 0.23 ± 0.17 logMAR in groups S and M, respectively (P = 0.231). Controlling for preoperative BCVA on ANCOVA testing, there were no significant differences in visual improvement between the two groups [F (1,26) = 0.02, P = 0.966 (95% CI) - 0.128 to 0.123)]. Scleral perforation (2:1), vitreous hemorrhage (3:2), and transient rise of intraocular pressure (3:4) all occurred at a low and similar rate between the two groups (S:M).ConclusionModified SB technique was non-inferior compared to the standard approach for anatomical and visual outcomes. Shortening surgical time while maintaining low complication rates makes this an appropriate approach to SB, especially for vitreoretinal surgery trainees.
