    OBJECTIVES: The purpose of this study was to examine the incidence of, and risk factors for, epiretinal membrane (ERM) surgery after an initial pars plana vitrectomy (PPV) for rhegmatogenous retinal detachment (RRD). METHODS: The records of consecutive patients (3,495 eyes of 3,387 patients) who underwent RRD repair at Fujita Health University Hospital between January 1, 2008, and February 28, 2019, were retrospectively reviewed. A total of 1,736 eyes without an ERM in preoperative optical coherence tomography were included in this study. RESULTS: The incidence of ERM surgery after RRD repair was 2.4%. The mean time from RRD repair to ERM surgery was 19.5±27.2 months. The odds ratios after adjusting for age and sex were as follows: the preoperative visual acuity (logarithm of the minimum angle of resolution, logMAR), 2.17 (p=0.02; 95% confidence interval [CI], 1.11-5.16); axial length, 1.38 (p=0.002; 95% CI, 1.12-1.72); 20-gauge vitreous surgery instruments, 3.82 (p<0.0001; 95% CI, 2.02-7.16); internal limiting membrane (ILM) peeling, 0.28 (p=0.033; 95% CI, 0.05-0.92). ERM surgery improved visual acuity from 0.36 to 0.01 logMAR, even at ≥1.5 years after RRD repair. CONCLUSIONS: Careful follow-up is required in the following cases: long axial length before RRD repair, low visual acuity, use of 20-gauge vitreous surgery instruments, and a lack of ILM peeling.

    OBJECTIVES: We compared the effects of sub-Tenon's capsule anesthesia (STA) and trans-Tenon's capsule retrobulbar anesthesia (TTRBA) in 68 patients with epiretinal membrane. METHODS: Either STA or TTRBA was induced with 3 mL of lidocaine (2%) before vitrectomy combined with phacoemulsification and aspiration (phacovitrectomy). Akinesia was evaluated by range of eye movement (ROEM) in upward, downward, nasal, and temporal directions at 4, 10, and 30 minutes after injection. Analgesia was evaluated with a visual analogue pain score, which ranged from 0 to 10. RESULTS: The mean cumulative ROEMs were 1.44±1.02 corneal diameters (CDs) at 4 minutes, 0.55±0.76 CDs at 10 minutes, and 0.26±0.33 CDs at 30 minutes in patients who received STA; these values were 0.39±0.35 CDs at 4 minutes, 0.22±0.30 CDs at 10 minutes, and 0.13±0.29 CDs at 30 minutes in patients who received TTRBA. At both 4 and 10 minutes, the cumulative ROEMs in all directions, as well as the temporal ROEMs, were significantly larger in patients who received STA than in patients who received TTRBA. Pain scores did not significantly differ between groups at any time point. CONCLUSIONS: STA and TTRBA produced identical degrees of analgesia, but akinesia was slower in patients who received STA. TTRBA might be preferable for patients undergoing brief vitrectomy.

    BACKGROUND AND OBJECTIVE: The authors developed a new technique for retrobulbar anesthesia and compared it with the conventional transcuta-neous method in 223 eyes undergoing vitrectomy. PATIENTS AND METHODS: In the new technique, a 24-mm-long 19-gauge curved cannula with a 27-gauge straight needle with an oval tip was inserted into the sub-Tenon's space, and then the oval-tipped needle was replaced with a 50-mm-long 25-gauge curved needle. Anesthetic was then injected into the muscle cone from the syringe. The authors compared 118 eyes undergoing vitrectomy with the new technique and 105 eyes undergoing the procedure with conventional anesthesia. RESULTS: The pain scores were 0.1 ± 0.32 for the new technique and 1.57 ± 0.73 for the conventional technique (P &lt .001). Additional anesthetic required was 0.1 ± 0.33 mL using the new technique and 0.3 ± 0.68 mL using the conventional method (P = .03). CONCLUSION: This novel approach to retrobulbar anesthesia using a guarded cannula is safe and effective, causing less pain than the conventional technique.

    Purpose. MaQaid (MaQ) is a new triamcinolone acetonide commercialised in Japan to visualize the vitreous. Because MaQ is preservative-free, it has a lower risk of ocular toxicities. However, since MaQ is only available as a powder, it needs suspenssion. Suspension does not always result uniformally, which causes poor visibility. This study reports a new MaQ suspension for better visibility. Methods. After medium addition to a MaQ vial, various methods were used. These included the use of (1) vortex mixer, (2) two syringes and a three-way stopcock, and (3) ultrasonic washer. We calculated suspended MaQ concentration (n = 5). To evaluate the reproducibility, we estimated the coefficient of variance (CV, n = 3). We used this MaQ for pig eyes, and vitreous visualization was simulated. Subsequently, we used this MaQ suspension for humans. Results. MaQ suspensions were sucessfull, and the concentrations of single particles increased significantly (P &lt; 0.01). The CV was 36.1% for the routine method and 9.03% ffor the new method. Administration of a suspended MaQ made it possible to clearly visualize the vitreous in both pig and human eyes. Conclusions. We devised new techniques for uniformal MaQ suspension. These new methods can compensate for the MaQ disadvantages and ensure a safety surgery.
