Background: To report the surgical safety of reinforced bio-interventional cyclodialysis with scleral allograft reinforcement. Methods: This was a consecutive case series of 243 eyes with open-angle glaucoma who underwent a bio-scaffolded cyclodialysis (BSC) procedure for uveoscleral outflow enhancement using allogeneic bio-spacers to maintain patency of the internal filtration conduit. Results: 79% of the eyes underwent concomitant phacoemulsification cataract surgery prior to BSC intervention, while the remaining eyes underwent stand-alone BSC surgery. All patients had a postoperative surgical safety period of at least 30 days. There were no sight-threatening or serious ocular adverse events. There was one case of prolonged iritis beyond 30 days, which resolved with topical treatment. Two cases (0.8%) of intraoperative and five (2%) of postoperative non-sight-threatening hyphema were without clinical sequelae, which resolved with conservative management. There were 11 cases of IOP elevation and one case of numeric hypotony without maculopathy, which resolved within the study period. The rate of secondary surgical intervention for IOP control was low, and overall, IOP for the cohort improved in the postoperative period, with 78.6% of eyes achieving IOP ≤ 18 mmHg without an increase in medications. Conclusions: Allogeneic biotissue for cyclodialysis intervention demonstrates a biocompatible ocular profile as an implantable material for internal scleral reinforcement during uveoscleral outflow enhancement surgery.

Our aim was to assess the therapeutic efficacy of a modified single-arm suture technique on traumatic cyclodialysis cleft with vitreoretinal injury. The procedure involved fixing a detached ciliary body using a single-armed 10-0 polypropylene suture under the assistance of a 29-gauge needle. Patients with a traumatic cyclodialysis cleft combined with an anterior and posterior segment injury who underwent modified internal cyclopexy together with vitreoretinal surgery were enrolled in this study. Ultrasound biomicroscopy (UBM) was used to diagnose and evaluate the cyclodialysis and anterior segment injury. B-scan ultrasonography was performed to assess the condition of the vitreous, retina and choroid. The surgical time and successful rate for repairing the cyclodialysis cleft were recorded. Preoperative and postoperative best-corrected visual acuity (BCVA), and intraocular pressure (IOP) were documented for assessment. The study included 20 eyes. The extent of the cyclodialysis cleft was from 30° to 360°. Besides a traumatic cyclodialysis cleft, the included cases also combined this with vitreous hemorrhages, retinal detachment, macular holes, choroid avulsion, and suprachoroidal hemorrhage. All the clefts were anatomically closed in one surgery. The average surgical time for fixing the cyclodialysis cleft was 2.68 ± 0.54 min/30° cleft. A significant improvement in LogMAR BCVA was observed from 2.94 ± 0.93 preoperatively to 1.81 ± 1.11 at the 6-month follow-up. IOP was elevated from 10.90 ± 6.18 mmHg preoperatively to 14.45 ± 2.35 mmHg at the 6-month follow-up. The modified single-armed suture technique was proved to be an effective method to fix the traumatic cyclodialysis cleft, which could facilitate the use of the procedure to repair chorioretinal disorders. It improved the BCVA and maintained the IOP with less postoperative complications. Full article
