“…On the other hand, retinal tacks insertion may lead to concerns about complications such as bleeding and glial cell proliferation. In fact, the safety of retinal tacking had previously been clinically confirmed in retinal detachment repair surgery, including follow-up cases for ten years [ 18 ]. According to our results, no retinal detachment was observed after our surgery.…”

Background To develop an effective surgical procedure for cellular scaffold epiretinal implantation in rhesus, facilitating subsequent epiretinal stem cell transplantation. Methods Retinal progenitors were seeded onto a poly(lactic-co-glycolic) acid (PLGA) scaffold. First, the cellular scaffolds were delivered by 18G catheter or retinal forceps into rabbit epiretinal space (n = 50). Then, the cell survival rate was evaluated by Cell Counting Kit-8 (CCK-8). Second, three methods of scaffold fixation, including adhesion after gas-liquid exchange (n = 1), tamponade by hydrogel (n = 1), and fixation by retinal tacks (n = 4), were performed in rhesus monkeys. After one month, fundus photography and SD-OCT were performed to assess the outcomes, and histological examination was performed to evaluate proliferation. Results The cell survival rate was significantly higher in the catheter group. Follow-up examination showed that retinal tack fixation was the only method to maintain the scaffolds attached to host retina for at least 3 weeks, which is the minimal time required for cell integration. Histological staining demonstrated slight glial fibrillary acidic protein (GFAP) accumulation in the retinal tack insertion area. Conclusions The established surgical procedure offers a new insight into research of epiretinal cell replacement therapy in rhesus eyes. The successful delivery and long-term fixation provide a prerequisite for cell migration and integration.

“…In addition, WAVs can improve the intraoperative field of view and offer better visibility and sharpness image of peripheral retina [ 5 ]. Currently, retinal tack had been abandoned by many surgeons due to unavailability and the concern of safety, we found it might be irreplaceable in cases of GRT with large inverted and rigid flap [ 8 ] and it may cause minimal or no retinal toxicity during as long as 21 years of follow-up [ 9 ]. To our knowledge, this is the first report of managing GRT with MIVS and retinal tacks in Taiwan.…”

BackgroundGiant retinal tear is usually challenging among retinal detachment with recurrent rate up to 45%. Here we presented a case of giant retinal tear being treated by microincision vitrectomy and retinal tacks fixation.Case presentationA 53-year-old male presented to our hospital with blurred vision of his right eye for one week with floaters and obscured sensation over nasal visual field. Ocular examination showed a 120 degree giant tear with large inverted flap and retinal detachment of his right eye. The BCVA was only naming digit. Under the impression of giant retinal tear with retinal detachment, 23-gauge pars plana vitrectomy were performed using Constellation high speed vitrectomy system and Topcon non-contact wide angle viewing system. During surgery, the vitreous was removed and perfluorocarbon liquids (PFCL) was injected to help unfolding the large inverted retinal flap. Three retinal tacks were applied to help fixating the large inverted retinal flap. Then, fluid-gas exchange, endolaser photocoagulation and intraocular silicone oil tamponade were performed as well. Initial reattachment of his right retina was achieved and his best corrected visual acuity improved to 0.3 of his right eye postoperatively. There was no recurrent retinal detachment during follow up period of 19 months.ConclusionsPrimary microincision vitrectomy using wide-angle viewing system with intraoperative perfluorocarbon liquids (PFCL) assistant, retinal tacks fixation and intraocular silicone oil tamponade appears to be safe and feasible for managing giant retinal tear with retinal detachment.

“…Such tacks were originally developed to treat retinal detachments (Puustjarvi and Terasvirta, 2001 ). They are pushed through the retina and anchored in the sclera.…”
