Pars Plana Vitrectomy for Epiretinal Membrane Removal

Check if the same lab product or an alternative is used in the 5 most similar protocols
Surgeries were performed by 3 surgeons (H.T., T.I., T.A.) using 25-gauge pars plana vitrectomy with the Stellaris PC (Bausch + Lomb, Rochester, NY, USA) or Constellation Vision System (Alcon Surgical, Fort Worth, TX, USA). Triamcinolone acetonide (TA; MaQaid, Wakamoto Pharmaceutical, Tokyo, Japan) was used to visualize the vitreous 21 . After cutting the core vitreous, TA was reinjected over the macula to grasp and peel the ERM with end-gripping forceps (Alcon Surgical). After removing the ERM, brilliant blue G (BBG; #0770 Sigma-Aldrich, St.
Louis, MO, USA)-the use of which was approved by the Institutional Review Board of the Nippon Medical School Hospital (approval number: 2012-033)-was used for ILM staining. ILM peeling was performed with an extendible diamond dusted sweeper (Alcon Surgical) and endgripping forceps (Fig. 1). Cataract surgery was combined with vitrectomy for 16 phakic eyes; 2 phakic eyes and 9 aphakic eyes were treated by vitrectomy only. Fluid-gas exchange (FGX) and intraocular gas tamponade with 20% SF6 were performed for all eyes with ERM in which intraoperative retinal breaks were found during a thorough peripheral vitreous shaving.

All surgeries were performed by a single surgeon (YGP). A three-port 25-gauge transconjunctival sutureless vitrectomy was performed to remove the ERM. After vitrectomy, the ERM was removed using end-gripping forceps (Alcon, Fort Worth, TX, USA). After removing the ERM, internal limiting membrane peeling was performed with 0.25% indocyanine green dye. ERM and internal limiting membrane peeling were started at the outer region around the fovea, particularly in the parafoveal area.

The surgeries were performed by 5 surgeons (P.K., D.P., J.C., N.W., and V.C.) with more than 10 years of experience in vitreoretinal surgery. A 3-port 23-gauge transconjunctival sutureless vitrectomy was performed using the CONSTELLATION Vision System (Alcon Laboratories, Inc, Fort Worth, Texas, USA). In all eyes, a central vitrectomy was performed and the posterior vitreous humor was separated from the retina. After vitrectomy the ERM and internal limiting membrane were removed using end-gripping forceps (Alcon, Fort Worth, TX, USA) with the assistance of Brilliant Blue G dye (0.05% w/v, Aurolab, India) or triamcinolone (40 mg/mL, Triesence; Alcon, Fort Worth, Texas, USA). The ERM and internal limiting membrane were removed from the central macular area up to the arcades.

PPV was performed by 2 experienced retinal specialists (SJW and KHP). A 23/25-gauge transconjunctival sutureless vitrectomy was performed using an Accurus 800CS surgical system (Alcon, Fort Worth, TX, USA) or Constellation system (Alcon) with contact lens (Hoya, Tokyo, Japan). Phacoemulsification with intraocular lens implantation was performed before vitrectomy in patients with significant cataract. The peeling of the ILM was performed using end-gripping forceps (Alcon). Triamcinolone acetonide (1%; Hanmi Pharmaceutical, Seoul, Korea) or 0.05% indocyanine green (Dong In Dang Pharmaceutical, Siheung, Korea) were used for staining and peeling of ILM. Foveal sparing ILM peeling was performed in 7 eyes and complete ILM peeling up to the temporal arcade was performed in the remaining 33 eyes. Gas tamponade with 14% perfluoropropane or 18% sulfur hexafluoride was done in 19 eyes. Prednisolone acetate (1%; Pred Forte, Allergan, Irvine, CA, USA) and 0.5% levofloxacin (Cravit; Santen Pharmaceutical, Osaka, Japan), were topically instilled 4 times a day for 4 weeks.

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
